本文介绍了一种使用Android平台实现自定义活动过渡动画的方法。通过监听按钮点击事件触发不同的动画效果，如淡入淡出和缩放动画。代码示例展示了如何使用`overridePendingTransition`来指定进入和退出动画资源。

public class Animation extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.activity_animation);

// Watch for button clicks.
Button button = (Button)findViewById(R.id.fade_animation);
button.setOnClickListener(mFadeListener);
button = (Button)findViewById(R.id.zoom_animation);
button.setOnClickListener(mZoomListener);
}

private OnClickListener mFadeListener = new OnClickListener() {
public void onClick(View v) {
// Request the next activity transition (here starting a new one).
startActivity(new Intent(Animation.this, Controls1.class));
// Supply a custom animation. This one will just fade the new
// activity on top. Note that we need to also supply an animation
// (here just doing nothing for the same amount of time) for the
// old activity to prevent it from going away too soon.
overridePendingTransition(R.anim.fade, R.anim.hold);

API Level 5

Call immediately after one of the flavors of startActivity(Intent) or finish() to specify an explicit transition animation to perform next.

Parameters

enterAnim	A resource ID of the animation resource to use for the incoming activity. Use 0 for no animation.
exitAnim	A resource ID of the animation resource to use for the outgoing activity. Use 0 for no animation.

}
};

private OnClickListener mZoomListener = new OnClickListener() {
public void onClick(View v) {
// Request the next activity transition (here starting a new one).
startActivity(new Intent(Animation.this, Controls1.class));
// This is a more complicated animation, involving transformations
// on both this (exit) and the new (enter) activity. Note how for
// the duration of the animation we force the exiting activity
// to be Z-ordered on top (even though it really isn't) to achieve
// the effect we want.
overridePendingTransition(R.anim.zoom_enter, R.anim.zoom_exit);
}
};
}
