設置Path路徑，貝賽爾曲線

1:  //設置Path路徑2:      private static void makePath(Path p) {3:          p.moveTo(10, 0);4:          p.cubicTo(100, -50, 200, 50, 300, 0);//貝賽爾曲線5:      }//mPos存的是字符串中每個字符的位置坐標

 1:  private float[] buildTextPositions(String text, float y, Paint paint) { 2:          float[] widths = new float[text.length()]; 3:          // initially get the widths for each char 4:          int n = paint.getTextWidths(text, widths); 5:          // now popuplate the array, interleaving spaces for the Y values X值為字符的寬 6:          float[] pos = new float[n * 2]; 7:          float accumulatedX = 0; 8:          for (int i = 0; i < n; i++) { 9:              pos[i * 2 + 0] = accumulatedX;10:              pos[i * 2 + 1] = y;11:              accumulatedX += widths[i];12:          }13:          return pos;14:      }

onDraw（）方法中：

畫 

1:  p.setColor(0x80FF0000);2:              canvas.drawLine(x, y, x, y + DY * 3, p);//(x,y)為基准線3:              p.setColor(Color.BLACK);4:   5:              canvas.translate(0, DY);6:              p.setTextAlign(Paint.Align.LEFT);7:              canvas.drawText(TEXT_L, x, y, p);//以（x,y）點Paint.Align.LEFT，畫畫 

1:  p.setColor(0xBB00FF00);2:      for (int i = 0; i < pos.length / 2; i++) {3:          canvas.drawLine(pos[i * 2 + 0], pos[i * 2 + 1] - DY, pos[i * 2 + 0],4:              pos[i * 2 + 1] + DY * 2, p);5:      }6:      p.setColor(Color.BLACK);7:   8:      p.setTextAlign(Paint.Align.LEFT);9:      canvas.drawPosText(POSTEXT, pos, p);

24.Typefaces：

 

獲得assets/fonts下的字體

1:  mFace = Typeface.createFromAsset(getContext().getAssets(),2:              "fonts/samplefont.ttf");onDraw()方法

1:  @Override2:          protected void onDraw(Canvas canvas) {3:              canvas.drawColor(Color.WHITE);4:   5:              mPaint.setTypeface(null);6:              canvas.drawText("Default", 10, 100, mPaint);7:              mPaint.setTypeface(mFace);8:              canvas.drawText("Custom", 10, 200, mPaint);9:          }

25.UnicodeChart：（沒看）

 

26.Vertices:(沒看) 觸摸一下，圖片走形

 

27.Xfermodes：

 

圓形畫法：

1:  static Bitmap makeDst(int w, int h) {2:          Bitmap bm = Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_8888);3:          Canvas c = new Canvas(bm);4:          Paint p = new Paint(Paint.ANTI_ALIAS_FLAG);5:          p.setColor(0xFFFFCC44);6:          c.drawOval(new RectF(0, 0, w * 3 / 4, h * 3 / 4), p);7:          return bm;8:      }正方形的畫法：

1:  static Bitmap makeSrc(int w, int h) {2:          Bitmap bm = Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_8888);3:          Canvas c = new Canvas(bm);4:          Paint p = new Paint(Paint.ANTI_ALIAS_FLAG);5:   6:          p.setColor(0xFF66AAFF);7:          c.drawRect(w / 3, h / 3, w * 19 / 20, h * 19 / 20, p);8:          return bm;9:      }背景馬塞克畫法：

1:  Bitmap bm = Bitmap.createBitmap(new int[] { 0xFFFFFFFF, 0xFFCCCCCC,2:                  0xFFCCCCCC, 0xFFFFFFFF }, 2, 2, Bitmap.Config.RGB_565);3:              mBG = new BitmapShader(bm, Shader.TileMode.REPEAT, Shader.TileMode.REPEAT);4:              Matrix m = new Matrix();5:              m.setScale(6, 6);// 放大6倍6:              mBG.setLocalMatrix(m);Xfermode數組：

 1:  private static final Xfermode[] sModes = { 2:              new PorterDuffXfermode(PorterDuff.Mode.CLEAR), 3:              new PorterDuffXfermode(PorterDuff.Mode.SRC), 4:              new PorterDuffXfermode(PorterDuff.Mode.DST), 5:              new PorterDuffXfermode(PorterDuff.Mode.SRC_OVER), 6:              new PorterDuffXfermode(PorterDuff.Mode.DST_OVER), 7:              new PorterDuffXfermode(PorterDuff.Mode.SRC_IN), 8:              new PorterDuffXfermode(PorterDuff.Mode.DST_IN), 9:              new PorterDuffXfermode(PorterDuff.Mode.SRC_OUT),10:              new PorterDuffXfermode(PorterDuff.Mode.DST_OUT),11:              new PorterDuffXfermode(PorterDuff.Mode.SRC_ATOP),12:              new PorterDuffXfermode(PorterDuff.Mode.DST_ATOP),13:              new PorterDuffXfermode(PorterDuff.Mode.XOR),14:              new PorterDuffXfermode(PorterDuff.Mode.DARKEN),15:              new PorterDuffXfermode(PorterDuff.Mode.LIGHTEN),16:              new PorterDuffXfermode(PorterDuff.Mode.MULTIPLY),17:              new PorterDuffXfermode(PorterDuff.Mode.SCREEN) };onDraw()方法：

 1:  @Override 2:          protected void onDraw(Canvas canvas) { 3:              canvas.drawColor(Color.WHITE); 4:    5:              Paint labelP = new Paint(Paint.ANTI_ALIAS_FLAG); 6:              labelP.setTextAlign(Paint.Align.CENTER); 7:    8:              Paint paint = new Paint(); 9:              paint.setFilterBitmap(false);10:   11:              canvas.translate(15, 35);12:   13:              int x = 0;14:              int y = 0;15:              for (int i = 0; i < sModes.length; i++) {16:                  // draw the border17:                  paint.setStyle(Paint.Style.STROKE);18:                  paint.setShader(null);// Pass null to clear any previous shader19:                  canvas.drawRect(x - 0.5f, y - 0.5f, x + W + 0.5f, y + H + 0.5f, paint);20:   21:                  // draw the checker-board pattern22:                  paint.setStyle(Paint.Style.FILL);23:                  paint.setShader(mBG);24:                  canvas.drawRect(x, y, x + W, y + H, paint);25:   26:                  // draw the src/dst example into our offscreen bitmap27:                  int sc = canvas.saveLayer(x, y, x + W, y + H, null,28:                      Canvas.MATRIX_SAVE_FLAG | Canvas.CLIP_SAVE_FLAG29:                          | Canvas.HAS_ALPHA_LAYER_SAVE_FLAG30:                          | Canvas.FULL_COLOR_LAYER_SAVE_FLAG31:                          | Canvas.CLIP_TO_LAYER_SAVE_FLAG);32:                  // canvas.save();33:                  canvas.translate(x, y);34:                  canvas.drawBitmap(mDstB, 0, 0, paint);35:                  paint.setXfermode(sModes[i]);36:                  canvas.drawBitmap(mSrcB, 0, 0, paint);37:                  paint.setXfermode(null);// Pass null to clear any previous xfermode38:                  canvas.restoreToCount(sc);39:                  // canvas.restore();40:  41:                  // draw the label42:                  canvas.drawText(sLabels[i], x + W / 2, y - labelP.getTextSize() / 2,43:                      labelP);44:   45:                  x += W + 10;46:   47:                  // wrap around when we've drawn enough for one row48:                  if ((i % ROW_MAX) == ROW_MAX - 1) {49:                      x = 0;50:                      y += H + 30;51:                  }52:              }53:          }注意：上面代碼一定要有這兩句，改成// canvas.save();都不成，會出現 

1:  int sc = canvas.saveLayer(x, y, x + W, y + H, null,2:                          Canvas.MATRIX_SAVE_FLAG | Canvas.CLIP_SAVE_FLAG3:                              | Canvas.HAS_ALPHA_LAYER_SAVE_FLAG4:                              | Canvas.FULL_COLOR_LAYER_SAVE_FLAG5:                              | Canvas.CLIP_TO_LAYER_SAVE_FLAG);6:                      // canvas.save();1:  canvas.restoreToCount(sc);2:                  // canvas.restore();

三.package com.example.android.apis.vIEw;

1.views/Animation/Shake,點Login按鈕後EditVIEw會有抖動

 

代碼如下：

 1:  public class Animation1 extends Activity implements View.OnClickListener {//設置單擊監聽，當然也可以直接在setOnClickListener裡new 2:   3:      @Override 4:      public void onCreate(Bundle savedInstanceState) { 5:          super.onCreate(savedInstanceState); 6:          setContentView(R.layout.animation_1); 7:    8:          View loginButton = findViewById(R.id.login); 9:          loginButton.setOnClickListener(this);10:      }11:   12:      public void onClick(View v) {//當loginButton被點擊時運行13:          Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);//Loads an Animation object from a resource14:          findViewById(R.id.pw).startAnimation(shake);//Start the specifIEd animation now.15:      }16:  }動畫文件在res/anim下

shake.XML為

1:  <?xml version="1.0" encoding="utf-8"?>2:  <translate XMLns:android="http://schemas.android.com/apk/res/android" android:fromXDelta="0" android:toXDelta="10" android:duration="1000" android:interpolator="@anim/cycle_7" />此為translate 類型動畫，從“0”移動到“10”，

注意：android:interpolator="@anim/cycle_7"這句為“插入器（竄改者）”

cycle_7.XML如下：

1:  <?xml version="1.0" encoding="utf-8"?>2:  <cycleInterpolator XMLns:android="http://schemas.android.com/apk/res/android" android:cycles="7" /> cycle為循環，表示shake的動畫在1秒內被循環7次

2.Animation2：最上面是一個ViewFlipper用於4個TextVIEw順序翻轉，最下面是一個Spinner，用於選擇翻轉方式（4種）

 

先學習下布局：（1個ViewFlipper 下面有4個TextVIEw）

 1:  <LinearLayout XMLns:android="http://schemas.android.com/apk/res/android" 2:          android:orientation="vertical" 3:          android:padding="10dip" 4:          android:layout_width="fill_parent" 5:          android:layout_height="wrap_content"> 6:   7:      <ViewFlipper android:id="@+id/flipper" 8:          android:layout_width="fill_parent" 9:          android:layout_height="wrap_content"10:          android:flipInterval="2000"11:                  android:layout_marginBottom="20dip" >12:                  <TextView13:                          android:layout_width="fill_parent"14:                          android:layout_height="wrap_content"15:                          android:gravity="center_horizontal"16:                          android:textSize="26sp"17:                          android:text="@string/animation_2_text_1"/>18:                  <TextView19:                          android:layout_width="fill_parent"20:                          android:layout_height="wrap_content"21:                          android:gravity="center_horizontal"22:                          android:textSize="26sp"23:                          android:text="@string/animation_2_text_2"/>24:                  <TextView25:                          android:layout_width="fill_parent"26:                          android:layout_height="wrap_content"27:                          android:gravity="center_horizontal"28:                          android:textSize="26sp"29:                          android:text="@string/animation_2_text_3"/>30:                  <TextView31:                          android:layout_width="fill_parent"32:                          android:layout_height="wrap_content"33:                          android:gravity="center_horizontal"34:                          android:textSize="26sp"35:                          android:text="@string/animation_2_text_4"/>36:      </ViewFlipper>37:  38:      <TextVIEw39:          android:layout_width="fill_parent"40:          android:layout_height="wrap_content"41:          android:layout_marginBottom="5dip"42:          android:text="@string/animation_2_instructions"43:      />44:  45:      <Spinner android:id="@+id/spinner"46:          android:layout_width="fill_parent"47:          android:layout_height="wrap_content"48:      />Spinner被選擇時，setInAnimation,setOutAnimation為Viewanimator的方法用於設置TextVIEw的入場，出場動畫

 1:  public void onItemSelected(AdapterView parent, VIEw v, int position, long id) { 2:          switch (position) { 3:    4:          case 0: 5:              mFlipper.setInAnimation(AnimationUtils.loadAnimation(this, 6:                  R.anim.push_up_in)); 7:              mFlipper.setOutAnimation(AnimationUtils.loadAnimation(this, 8:                  R.anim.push_up_out)); 9:              break;10:          case 1:11:              mFlipper.setInAnimation(AnimationUtils.loadAnimation(this,12:                  R.anim.push_left_in));13:              mFlipper.setOutAnimation(AnimationUtils.loadAnimation(this,14:                  R.anim.push_left_out));15:              break;16:          case 2:17:              mFlipper.setInAnimation(AnimationUtils.loadAnimation(this,18:                  android.R.anim.fade_in));19:              mFlipper.setOutAnimation(AnimationUtils.loadAnimation(this,20:                  android.R.anim.fade_out));21:              break;22:          default:23:              mFlipper.setInAnimation(AnimationUtils.loadAnimation(this,24:                  R.anim.hyperspace_in));25:              mFlipper.setOutAnimation(AnimationUtils.loadAnimation(this,26:                  R.anim.hyperspace_out));27:              break;28:          }29:      }res/anim/push_up_in.XML

1:  <?xml version="1.0" encoding="utf-8"?>2:  <set xmlns:android="http://schemas.android.com/apk/res/android">3:      <translate android:fromYDelta="100%p" android:toYDelta="0" android:duration="300"/>4:      <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="300" />5:  </set>6:  res/anim/push_up_out.XML

1:  <?xml version="1.0" encoding="utf-8"?>2:  <set xmlns:android="http://schemas.android.com/apk/res/android">3:      <translate android:fromYDelta="0" android:toYDelta="-100%p" android:duration="300"/>4:      <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="300" />5:  </set>6:  res/anim/push_left_in.XML

 1:  <?xml version="1.0" encoding="utf-8"?> 2:   3:  <set XMLns:android="http://schemas.android.com/apk/res/android" 4:      android:shareInterpolator="false"> 5:   6:      <scale android:interpolator="@android:anim/accelerate_decelerate_interpolator" 7:          android:fromXScale="1.0" android:toXScale="1.4" android:fromYScale="1.0" 8:          android:toYScale="0.6" android:pivotX="50%" android:pivotY="50%" 9:          android:fillAfter="false" android:duration="700" />10:  11:  12:      <set android:interpolator="@android:anim/accelerate_interpolator"13:          android:startOffset="700">14:  15:          <scale android:fromXScale="1.4" android:toXScale="0.0"16:              android:fromYScale="0.6" android:toYScale="0.0" android:pivotX="50%"17:              android:pivotY="50%" android:duration="400" />18:  19:          <rotate android:fromDegrees="0" android:toDegrees="-45"20:              android:toYScale="0.0" android:pivotX="50%" android:pivotY="50%"21:              android:duration="400" />22:      </set>23:  24:  </set>以上幾個動畫可以直接用在ImageVIEw上

3.Animation3:

主要是Interpolator的用法。public void setInterpolator (Interpolator i)Sets the acceleration curve for this animation. Defaults to a linear interpolation（設置動畫的加速度效果）

首先在第一個TextVIEw中加入動畫效果： 

 1:  final View target = findViewById(R.id.target);//TextView 2:  final View targetParent = (View) target.getParent();//TextView的父vIEw 3:   4:  Animation a = new TranslateAnimation(0.0f, targetParent.getWidth()//設置位移動畫 5:      - target.getWidth() - targetParent.getPaddingLeft() 6:      - targetParent.getPaddingRight(), 0.0f, 0.0f); 7:  a.setDuration(1000);//持續1秒 8:  a.setStartOffset(300); 9:  a.setRepeatMode(Animation.RESTART);//重復10:  a.setRepeatCount(Animation.INFINITE);//無限次android自帶的7種Interpolator 效果

 1:  switch (position) { 2:          case 0: 3:              a.setInterpolator(AnimationUtils.loadInterpolator(this, 4:                  android.R.anim.accelerate_interpolator)); 5:              break; 6:          case 1: 7:              a.setInterpolator(AnimationUtils.loadInterpolator(this, 8:                  android.R.anim.decelerate_interpolator)); 9:              break;10:          case 2:11:              a.setInterpolator(AnimationUtils.loadInterpolator(this,12:                  android.R.anim.accelerate_decelerate_interpolator));13:              break;14:          case 3:15:              a.setInterpolator(AnimationUtils.loadInterpolator(this,16:                  android.R.anim.anticipate_interpolator));17:              break;18:          case 4:19:              a.setInterpolator(AnimationUtils.loadInterpolator(this,20:                  android.R.anim.overshoot_interpolator));21:              break;22:          case 5:23:              a.setInterpolator(AnimationUtils.loadInterpolator(this,24:                  android.R.anim.anticipate_overshoot_interpolator));25:              break;26:          case 6:27:              a.setInterpolator(AnimationUtils.loadInterpolator(this,28:                  android.R.anim.bounce_interpolator));29:              break;30:          }31:   32:          target.startAnimation(a);

4. Transition3d：package com.example.android.apis.animation;（沒看全）

圖片切換3D效果的動畫

 

layout為一個FrameLayout裡放入一個ListView和一個ImageView ，動畫是這兩個VIEw的切換效果

5.AutoComplete1

自動完成TextVIEw，主要實現自動提示國家的英文

 

 這塊的layout布局

 1:  <LinearLayout 2:          android:orientation="horizontal" 3:          android:layout_width="fill_parent" 4:          android:layout_height="wrap_content"> 5:   6:          <TextView 7:              android:layout_width="wrap_content" 8:              android:layout_height="wrap_content" 9:              android:text="@string/autocomplete_1_country" />10:  11:          <AutoCompleteTextVIEw android:id="@+id/edit"12:              android:layout_width="fill_parent"13:              android:layout_height="wrap_content"/>14:  15:      </LinearLayout>在AutoCompeteTextVIEw裡設置個Adapter

1:  ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,2:              android.R.layout.simple_dropdown_item_1line, COUNTRIES);3:          AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.edit);4:          textView.setAdapter(adapter);第二行的COUNTRIES為一個數組：

 1:  static final String[] COUNTRIES = new String[] { "Afghanistan", "Albania", 2:          "Algeria", "American Samoa", "Andorra", "Angola", "Anguilla", 3:          "Antarctica", "Antigua and Barbuda", "Argentina", "Armenia", "Aruba", 4:          "Australia", "Austria", "Azerbaijan", "Bahrain", "Bangladesh", 5:          "BarbaDOS", "Belarus", "Belgium", "Belize", "Benin", "Bermuda", "Bhutan", 6:          "Bolivia", "Bosnia and Herzegovina", "Botswana", "Bouvet Island", 7:          "Brazil", "British Indian Ocean Territory", "British Virgin Islands", 8:          "Brunei", "Bulgaria", "Burkina Faso", "Burundi", "Cote d'Ivoire", 9:          "Cambodia", "Cameroon", "Canada", "Cape Verde", "Cayman Islands",10:          "Central African Republic", "Chad", "Chile", "China", "Christmas Island",11:          "Cocos (Keeling) Islands", "Colombia", "Comoros", "Congo",12:          "Cook Islands", "Costa Rica", "Croatia", "Cuba", "Cyprus",13:          "Czech Republic", "Democratic Republic of the Congo", "Denmark",14:          "Djibouti", "Dominica", "Dominican Republic", "East Timor", "Ecuador",15:          "Egypt", "El Salvador", "Equatorial Guinea", "Eritrea", "Estonia",16:          "Ethiopia", "Faeroe Islands", "Falkland Islands", "Fiji", "Finland",17:          "Former Yugoslav Republic of Macedonia", "France", "French Guiana",18:          "French Polynesia", "French Southern Territories", "Gabon", "Georgia",19:          "Germany", "Ghana", "Gibraltar", "Greece", "Greenland", "Grenada",20:          "Guadeloupe", "Guam", "Guatemala", "Guinea", "Guinea-Bissau", "Guyana",21:          "Haiti", "Heard Island and McDonald Islands", "Honduras", "Hong Kong",22:          "Hungary", "Iceland", "India", "Indonesia", "Iran", "Iraq", "Ireland",23:          "Israel", "Italy", "Jamaica", "Japan", "Jordan", "Kazakhstan", "Kenya",24:          "Kiribati", "Kuwait", "Kyrgyzstan", "Laos", "Latvia", "Lebanon",25:          "Lesotho", "Liberia", "Libya", "Liechtenstein", "Lithuania",26:          "Luxembourg", "Macau", "Madagascar", "Malawi", "Malaysia", "Maldives",27:          "Mali", "Malta", "Marshall Islands", "Martinique", "Mauritania",28:          "Mauritius", "Mayotte", "Mexico", "Micronesia", "Moldova", "Monaco",29:          "Mongolia", "Montserrat", "Morocco", "Mozambique", "Myanmar", "Namibia",30:          "Nauru", "Nepal", "Netherlands", "Netherlands Antilles", "New Caledonia",31:          "New Zealand", "Nicaragua", "Niger", "Nigeria", "Niue", "Norfolk Island",32:          "North Korea", "Northern Marianas", "Norway", "Oman", "Pakistan",33:          "Palau", "Panama", "Papua New Guinea", "Paraguay", "Peru", "Philippines",34:          "Pitcairn Islands", "Poland", "Portugal", "Puerto Rico", "Qatar",35:          "Reunion", "Romania", "Russia", "Rwanda", "Sqo Tome and Principe",36:          "Saint Helena", "Saint Kitts and Nevis", "Saint Lucia",37:          "Saint Pierre and Miquelon", "Saint Vincent and the Grenadines", "Samoa",38:          "San Marino", "Saudi Arabia", "Senegal", "Seychelles", "Sierra Leone",39:          "Singapore", "Slovakia", "Slovenia", "Solomon Islands", "Somalia",40:          "South Africa", "South Georgia and the South Sandwich Islands",41:          "South Korea", "Spain", "Sri Lanka", "Sudan", "Suriname",42:          "Svalbard and Jan Mayen", "Swaziland", "Sweden", "Switzerland", "Syria",43:          "Taiwan", "Tajikistan", "Tanzania", "Thailand", "The Bahamas",44:          "The Gambia", "Togo", "Tokelau", "Tonga", "Trinidad and Tobago",45:          "Tunisia", "Turkey", "Turkmenistan", "Turks and Caicos Islands",46:          "Tuvalu", "Virgin Islands", "Uganda", "Ukraine", "United Arab Emirates",47:          "United Kingdom", "United States",48:          "United States Minor Outlying Islands", "Uruguay", "Uzbekistan",49:          "Vanuatu", "Vatican City", "Venezuela", "VIEtnam", "Wallis and Futuna",50:          "Western Sahara", "Yemen", "Yugoslavia", "Zambia", "Zimbabwe" };

6.AutoComplete2

 

和AutoComplete1只是布局不一樣，注意第5行的android:gravity=”bottom”

 1:  <LinearLayout XMLns:android="http://schemas.android.com/apk/res/android"  2:      android:orIEntation="vertical" 3:      android:layout_width="fill_parent"  4:      android:layout_height="fill_parent" 5:      android:gravity="bottom"> 6:   7:      <Button 8:          android:layout_width="wrap_content" 9:          android:layout_height="wrap_content"10:          android:text="@string/autocomplete_2_focus" />11:  12:      <LinearLayout

7.AutoComplete6（沒看出和上面的有什麼不同的功能）

 

布局要注意：為MutiAutoCompleteTextVIEw

1:  <TextView2:              android:layout_width="wrap_content"3:              android:layout_height="wrap_content"4:              android:text="@string/autocomplete_7_country" />5:  6:          <MultiAutoCompleteTextVIEw android:id="@+id/edit"7:              android:layout_width="fill_parent"8:              android:layout_height="wrap_content"/>設置Adapter

1:  ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,2:                  android.R.layout.simple_dropdown_item_1line, COUNTRIES);3:          MultiAutoCompleteTextView textView = (MultiAutoCompleteTextView) findViewById(R.id.edit);4:          textView.setAdapter(adapter);5:          textView.setTokenizer(new MultiAutoCompleteTextVIEw.CommaTokenizer());

8.Baseline1:

 

直接加載的layout布局：

 1:  <TextVIEw 2:          android:layout_width="wrap_content" 3:          android:layout_height="wrap_content" 4:          android:layout_marginRight="30dip" 5:          android:text="@string/baseline_1_label" /> 6:   7:      <Button 8:          android:layout_width="wrap_content" 9:          android:layout_height="wrap_content"10:          android:layout_marginRight="30dip"11:          android:text="@string/baseline_1_button" />第4行和第10行的

android:layout_marginRight="30dip"

為此TextVIEw右邊有30像素的空白

9.Baseline3

 

布局：

注意：第11行的android:layout_gravity="center_vertical"表示在父VIEw的中心

 1:  <LinearLayout 2:          android:orientation="horizontal" 3:          android:layout_width="fill_parent" 4:          android:layout_weight="1.0" 5:          android:layout_height="0dip"> 6:   7:          <TextView 8:              android:layout_width="wrap_content" 9:              android:layout_height="wrap_content"10:              android:layout_marginRight="3dip"11:              android:layout_gravity="center_vertical"12:              android:text="@string/baseline_3_label" />13:  14:          <Button15:              android:layout_width="wrap_content"16:              android:layout_height="wrap_content"17:              android:layout_marginRight="3dip"18:              android:layout_gravity="center_vertical"19:              android:text="@string/baseline_3_button" />20:  21:          <TextVIEw22:              android:layout_width="wrap_content"23:              android:layout_height="wrap_content"24:              android:layout_gravity="center_vertical"25:              android:textSize="20sp"26:              android:text="@string/baseline_3_bigger" />27:  28:      </LinearLayout>

10.Baseline4

 

此布局就是父View的Layout為android:orientation="horizontal"水平布局，然後子vIEw再應用android:layout_gravity="center_vertical"和android:gravity="bottom"

11.Baseline6(沒明白效果)

 

布局:

 1:  <RelativeLayout XMLns:android="http://schemas.android.com/apk/res/android" 2:      android:layout_width="fill_parent" 3:      android:layout_height="fill_parent"> 4:   5:      <EditText android:id="@+id/anchor" 6:          android:layout_width="fill_parent" 7:          android:layout_height="fill_parent" 8:          android:textSize="20sp" 9:          android:text="@string/baseline_6_multi_line" />10:  11:      <TextVIEw12:          android:layout_width="wrap_content"13:          android:layout_height="wrap_content"14:          android:layout_alignBaseline="@id/anchor"15:          android:layout_alignRight="@id/anchor"16:          android:text="@string/baseline_6_baseline" />17:  18:  </RelativeLayout>

12.Baseline7

 

布局:

注意:TextVIEw android:id="@+id/anchor"的android:layout_alignParentTop="true"和android:layout_alignParentLeft="true"設置它為父VIEW的左上角

第16行android:layout_alignBaseline="@id/anchor",設置此VIEw在anchor的一條線上

 1:  <RelativeLayout XMLns:android="http://schemas.android.com/apk/res/android" 2:      android:layout_width="fill_parent" 3:      android:layout_height="fill_parent"> 4:   5:      <TextView android:id="@+id/anchor" 6:          android:layout_width="wrap_content" 7:          android:layout_height="wrap_content" 8:          android:layout_alignParentTop="true" 9:          android:layout_alignParentLeft="true"10:          android:textStyle="bold"11:          android:text="@string/baseline_7_fat" />12:  13:      <TextVIEw14:          android:layout_width="wrap_content"15:          android:layout_alignParentRight="true"16:          android:layout_alignBaseline="@id/anchor"17:          android:layout_height="wrap_content"18:          android:text="@string/baseline_7_lean" />19:      20:  </RelativeLayout>

13.Buttons1：

 

主要是布局：

第二個按鈕為小按鈕，第14行style="?android:attr/buttonStyleSmall" 

第三個按鈕為開關按鈕，ToggleButton

 1:  <LinearLayout 2:          android:layout_width="wrap_content" 3:          android:layout_height="wrap_content" 4:          android:orIEntation="vertical"> 5:           6:          <!-- Regular sized buttons --> 7:          <Button android:id="@+id/button_normal" 8:              android:text="@string/buttons_1_normal" 9:              android:layout_width="wrap_content"10:              android:layout_height="wrap_content" />11:  12:          <!-- Small buttons -->13:          <Button android:id="@+id/button_small"14:              style="?android:attr/buttonStyleSmall"15:              android:text="@string/buttons_1_small"16:              android:layout_width="wrap_content"17:              android:layout_height="wrap_content" />18:  19:          <ToggleButton android:id="@+id/button_toggle"20:              android:text="@string/buttons_1_toggle"21:              android:layout_width="wrap_content"22:              android:layout_height="wrap_content" />23:              24:      </LinearLayout>

14.ChronometerDemo 計時器

 

布局：

 1:  <Chronometer android:id="@+id/chronometer" 2:          android:format="@string/chronometer_initial_format" 3:          android:layout_width="wrap_content" android:layout_height="wrap_content" 4:          android:layout_weight="0" android:paddingBottom="30dip" 5:          android:paddingTop="30dip" /> 6:   7:      <Button android:id="@+id/start" android:layout_width="wrap_content" 8:          android:layout_height="wrap_content" android:text="@string/chronometer_start"> 9:          <requestFocus />10:      </Button>對Chronometer控件的操作：

設置監聽：

 1:  button = (Button) findViewById(R.id.start); 2:          button.setOnClickListener(mStartListener); 3:   4:          button = (Button) findViewById(R.id.stop); 5:          button.setOnClickListener(mStopListener); 6:   7:          button = (Button) findViewById(R.id.reset); 8:          button.setOnClickListener(mResetListener); 9:  10:          button = (Button) findViewById(R.id.set_format);11:          button.setOnClickListener(mSetFormatListener);12:  13:          button = (Button) findVIEwById(R.id.clear_format);14:          button.setOnClickListener(mClearFormatListener);監聽事件：

 1:  View.OnClickListener mStartListener = new OnClickListener() { 2:          public void onClick(View v) { 3:              mChronometer.start(); 4:          } 5:      }; 6:   7:      View.OnClickListener mStopListener = new OnClickListener() { 8:          public void onClick(View v) { 9:              mChronometer.stop();10:          }11:      };12:  13:      View.OnClickListener mResetListener = new OnClickListener() {14:          public void onClick(View v) {15:              mChronometer.setBase(SystemClock.elapsedRealtime());16:          }17:      };18:  19:      View.OnClickListener mSetFormatListener = new OnClickListener() {20:          public void onClick(View v) {21:              mChronometer.setFormat("Formatted time (%s)");22:          }23:      };24:  25:      View.OnClickListener mClearFormatListener = new OnClickListener() {26:          public void onClick(VIEw v) {27:              mChronometer.setFormat(null);28:          }29:      };

15.Controls1：

 

 

 
 此圖的布局：

1:  <CheckBox android:id="@+id/star"2:             style="?android:attr/starStyle"3:             android:layout_width="wrap_content"4:             android:layout_height="wrap_content"5:             android:text="@string/controls_1_star" />注意這幾個布局：
