overridePendingTransition在TabActivity里失效的解决办法

I found out that the problem was because my view was a sub-activity inside a tab.
To correctly override the transitions I've overridden the onPause method on the TabActivity and it now works as expected.
翻译过来的意思大概是：

我发现这个问题是因为我的View是一个Tab里面的子Activity。我在继承了TabActivity的子类Activity中重写OnPause方法后，动画正常。

//没动画的代码
@Override
public void onClick(View v) {
    switch (v.getId()) {
    case R.id.rlUpdate:
        Intent intent = new Intent(v.getContext(), NeedUpdateActivity.class);
        startActivity(intent);
        overridePendingTransition(R.anim.push_left_in, R.anim.push_left_out);
        break;
    case .....
    }
}
//正常动画的代码
public class MainActivity extends TabActivity {
    .....
    @Override
    protected void onPause() {
        super.onPause();
        overridePendingTransition(R.anim.push_left_in, R.anim.push_left_out);
    }
}
