如何客制化某两个activity切换时的窗口动画？

[DESCRIPTION]
两个acitivity在做切换时会有一个过渡的窗口动画效果，默认情况下这个窗口动画的动画效果是由php?mod=tag&id=6090" target="_blank" class="relatedlink">Framework统一控制的。如果想客制化某两个窗口切换时的动画效果，应该怎么做?
[SOLUTION]
Activity.java中提供了一个可供ap端override窗口切换动画效果的方法：
public void overridePendingTransition(int enterAnim, int exitAnim)
以Launcher中使用这个API的代码为例：
// Launcher.java
public void onCLIckVoiceButton(View v) {
v.performHapticFeedback(HapticFeedbackConstants.VIRTUAL_KEY);
try {
final SearchManager searchManager =
(SearchManager) getSystEMService(Context.SEARCH_SERVICE);
ComponentName activityName = searchManager.getGlobalSearchActivity();
Intent intent = new Intent(RecognizerIntent.ACTION_WEB_SEARCH);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
if (activityName ！= null) {
intent.setPackage(activityName.getPackageName());
}
startActivity(null, intent, "onClickVoiceButton");
// R.anim.fade_in_fast和R.anim.fade_out_fast分别表示要启动的activity 窗口的
enterAnim资源ID和exitAnim资源ID
overridePendingTransition(R.anim.fade_in_fast, R.anim.fade_out_fast);
} catch (ActivityNotFoundException e) {
Intent intent = new Intent(RecognizerIntent.ACTION_WEB_SEARCH);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivitySafely(null, intent, "onClickVoiceButton");
}
}
