alt="" /></p><p>MainActivity的布局：3个Button，点击后，分别跳转到不同的Activity。</p><p></p><pre name="code" class="java"><Button android:id="@+id/btn1"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginBottom="10dp"android:text="Alpha Aniamtion"/><Button android:id="@+id/btn2"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginBottom="10dp"android:text="Translate Animation"/><Button android:id="@+id/btn3"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginBottom="10dp"android:text="Translate slide from right to left"/>

一开始采取了比较麻烦的方法，

@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.btn1:Intent intent_alpha = new Intent(MainActivity.this, ActivityAlpha.class);startActivity(intent_alpha);overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);break;case R.id.btn2:Intent intent_trans = new Intent(MainActivity.this, ActivityTranslation.class);startActivity(intent_trans);overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right);break;case R.id.btn3:Intent intent_slide = new Intent(MainActivity.this, ActivityTranslation.class);startActivity(intent_slide);overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);break;default:break;}}

在每个startActivity（）方法后面加上 overridePendingTransition(android.R.anim.XXin, android.R.anim.XXout);

这两个参数跟别是即将进入的新的Activity要执行的动画，和即将看不见的原来的Activity要执行的动画。

同样，别忘了，在新的Activity退出时也要执行动画的话，可以覆写onKeyDown方法。

@Overridepublic boolean onKeyDown(int keyCode, KeyEvent event){if (keyCode == KeyEvent.KEYCODE_BACK) {this.finish();overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);}return false;}

这次是在finish的后面加上那个方法。如果在一些非Activity类中调用的话，fragment啥的，因为调用者是Activity（我猜），就在前面加getActivity（），getParent（）啥的就行啦。

这里用到的有几个是android自带的动画的方法。

如果要自己写的话，可以在res里面新建文件夹anim，在里面新建动画的xml，如：

in_from_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"android:interpolator="@android:anim/accelerate_interpolator" ><translateandroid:duration="500"android:fromXDelta="100%p"android:toXDelta="0%p" /></set>

集合set里面可以添加多种属性的动画，translate，scale，alpha等。

——————————————————————————————分————割————线————————————————————————————————

另外一种实现的方法是，在style中声明一个style，并在想要执行动画的Activity的Manifest文件中设置theme

<style name="XXXX" parent="@android:style/XXXXX" mce_bogus="1">      <item name="android:activityOpenEnterAnimation">@anim/push_left_in</item>          <span style="color:#ff0000;">打开</span>Activity时，<span style="font-family: Arial, Helvetica, sans-serif;"><span style="color:#ff0000;">即将进入</span>的Activity执行的动画</span><item name="android:activityOpenExitAnimation">@anim/push_left_out</item>           <span style="color:#ff0000;"> </span><span style="font-family: Arial, Helvetica, sans-serif;"><span style="color:#ff0000;">打开</span>Activity时，</span><span style="font-family: Arial, Helvetica, sans-serif;"><span style="color:#ff0000;">即将退出</span>的Activity执行的</span><span style="font-family: Arial, Helvetica, sans-serif;">动画 </span><span style="font-family: Arial, Helvetica, sans-serif;">  </span>
