Android 手勢滑動動畫效果收集整理

一 、 利用View自身的setAnimation來實現動畫（TextView、ImageView、ListView等都可以實現)

java代碼：
[java]
public void UpdateViewContent(){ 
    TextView txtview = (TextView)findViewById(R.id.content_view); 
    txtview.setText(MyGetNextText()); 
    txtview.setAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_in)); 
} 

Xml代碼：

[html] 
<span style="font-weight: normal;"><?xml version="1.0" encoding="utf-8"?> 
<set xmlns:android="http://schemas.android.com/apk/res/android"> 
    <translate android:fromXDelta="0" android:toXDelta="100%" android:duration="300"/> 
    <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="300" /> 
</set></span> 

關鍵代碼：
[html] 
<span style="font-weight: normal; ">txtview.setAnimation(AnimationUtils.loadAnimation(this, R.anim.push_left_in));</span>

<?xml version="1.0" encoding="utf-8"?>  
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"

為了使其滑動時有一定的特效，我們需要加入Animation效果，說到Animation，我們先看下如何在Android中實現自定義Animation。自定義的Animation是以XML格式定義的，定義好的XML文件存放在res/anim中。

　　一般的Animation有以下四種類型：
　　1. Alpha：漸變透明度動畫效果
　　2. Scale：漸變尺寸伸縮動畫效果
　　3. Translate：畫面轉換位置移動動畫效果
　　4. Rotate：畫面轉換位置移動動畫效果
