Android自定義UI手勢密碼終結版

編輯：關於Android編程

之前寫過3篇手勢密碼的demo,不過沒有集成到真實的企業項目中，這幾天正好領到一個手勢密碼項目，昨天剛好弄完，今天抽空整理下，目前還沒有完善，有一些地方需要更改，不過基本的流程都可以跑通了。

源碼下載地址：http://xiazai.jb51.net/201610/yuanma/AndroidGestureLock(jb51.net).rar

先看主界面的入口把、裡面有2個button(一個是設置手勢密碼、一個是校驗手勢密碼)
activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 xmlns:tools="http://schemas.android.com/tools" 
 android:layout_width="match_parent" 
 android:layout_height="match_parent" 
 tools:context="com.example.gesturelock.MainActivity" > 
 
 <Button 
 android:id="@+id/setting" 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" 
 android:layout_alignParentLeft="true" 
 android:layout_alignParentTop="true" 
 android:text="設置" /> 
 
 <Button 
 android:id="@+id/verify" 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content" 
 android:layout_alignParentTop="true" 
 android:layout_toRightOf="@+id/setting" 
 android:text="校驗" /> 
 
</RelativeLayout>

在看主界面的代碼把
MainActivity

package com.example.gesturelock; 
 
import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
 
public class MainActivity extends Activity implements OnClickListener { 
 
 private Button setting, verify; 
 
 @Override 
 protected void onCreate(Bundle savedInstanceState) { 
 super.onCreate(savedInstanceState); 
 setContentView(R.layout.activity_main); 
 setting = (Button) findViewById(R.id.setting); 
 verify = (Button) findViewById(R.id.verify); 
 setting.setOnClickListener(this); 
 verify.setOnClickListener(this); 
 } 
 
 @Override 
 public void onClick(View v) { 
 switch (v.getId()) { 
 case R.id.setting: 
 
  startActivity(new Intent(this, GestureEditActivity.class)); 
  break; 
 case R.id.verify: 
  startActivity(new Intent(this, GestureVerifyActivity.class)); 
 
  break; 
 
 default: 
  break; 
 } 
 } 
 
}

想了想還是先貼數據庫把---就是存放手勢密碼、以及還可以輸入的手勢密碼次數
publicSQLiteOpenHelper

package com.example.gesturelock; 
 
import android.content.ContentValues; 
import android.content.Context;

接下裡再看工具類把--就是輸入的手勢密碼簡單MD5加密、以及屏幕尺寸工具類

/** 
 * 
 */ 
package com.example.gesturelock; 
 
import android.content.Context; 
import android.view.WindowManager; 
 
public class AppUtil { 
 
 /** 
 * 獲取屏幕分辨�? 
 * @param context 
 * @return 
 */ 
 public static int[] getScreenDispaly(Context context) { 
 WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); 
 @SuppressWarnings("deprecation") 
 int width = windowManager.getDefaultDisplay().getWidth(); 
 @SuppressWarnings("deprecation") 
 int height = windowManager.getDefaultDisplay().getHeight(); 
 int result[] = { width, height }; 
 return result; 
 } 
 
} 


package com.example.gesturelock; 
 
import java.security.MessageDigest; 
import java.security.NoSuchAlgorithmException; 
 
import android.util.Log; 
 
public class MD5EncodeUtil { 
 public static String MD5Ecode(String gesture){ 
 Log.i("GYL","gesture---"+gesture.toString()); 
 byte[] toencode=gesture.toString().getBytes(); 
 Log.i("GYL","byte[]----"+toencode.toString()); 
  
 try{ 
  MessageDigest md5=MessageDigest.getInstance("MD5"); 
  md5.reset(); 
  md5.update(toencode); 
  return HexEncode(md5.digest()); 
 }catch(NoSuchAlgorithmException e){ 
  e.printStackTrace(); 
 } 
 return ""; 
 } 
 public static String HexEncode(byte[] toencode){ 
 StringBuilder sb=new StringBuilder(toencode.length*2); 
 for(byte b:toencode){ 
  sb.append(Integer.toHexString((b&0xf0)>>>4)); 
  sb.append(Integer.toHexString(b&0x0f));  
 } 
 return sb.toString().toUpperCase(); 
 } 
}

一步步來，接下來看bean類，就是每個圓點的屬性
Constants

package com.example.gesturelock; 
 
public class Constants { 
 public static final int POINT_STATE_NORMAL = 0; // 正常狀態 
 public static final int POINT_STATE_SELECTED = 1; // 按下狀態 
 public static final int POINT_STATE_WRONG = 2; // 錯誤狀態 
 
}

GesturePoint

接下來就看那9個點的繪制界面
