LocalActivityManager destroyActivity with animation

Question

I wanna add animation effect when a activity call back method.And I use activityGroup to implement activitymanger and use LocalActivityManager to start and back any activity.

when start an activity add the animation use the follow code

public static void startActivity(Intent intent, String id) {

    View view = mLocalActivityManager.startActivity(id,
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();

    Animation hyperspaceJump = AnimationUtils.loadAnimation(mActivityGroup,
            R.anim.dync_in_from_right);
    view.startAnimation(hyperspaceJump);

    view.setTag(id);
    mPreviousActivityTag = getCurrentActivityTag();
    mViewContainer.addView(view);
}

but i don't know how to add the animation effect when an activity return back to the one , which start the cur activity. the back method is like that

public static void removeCurrentActivity() {

    String tag = getCurrentActivityTag();
    if (com.ct.ipaipai.global.Utily.isStringEmpty(tag) == false) {

        int cnt = getActivityCount();
        mViewContainer.removeViewAt(cnt - 1);
        View view = mLocalActivityManager.destroyActivity(tag, true).getDecorView();
    }
}

any one know that?

thanks

I don't know which ActivityGroup you are using, but when I used ActivityGroup sometimes in past, I did something like this

String tag = getCurrentActivityTag();
LocalActivityManager manager = getLocalActivityManager();
Animation animation = null;
animation = AnimationUtils.loadAnimation(this, R.anim.de_rail);
Window oldWindow = manager.getCurrentActivity().getWindow();
if(oldWindow != null)
{
    View v =oldWindow.getDecorView();
    v.setBackgroundResource(R.drawable.app_pink_background);
    v.startAnimation(animation);                
}
manager.destroyActivity(tag, true);
// now set old Activity View
Intent lastIntent = manager.getActivity(lastId).getIntent();
Window newWindow = manager.startActivity(lastId, lastIntent);
if(newWindow != null)
{
    View view = newWindow.getDecorView();
    setContentView(view);           
}

where R.anim.de_rail, which was actually de_rail.xml was something like this:

<?xml version="1.0" encoding="utf-8"?>
<translate
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="0%p"
    android:toXDelta="100%p"
    android:duration="400" />

You can find my modified version here. It shows animation on start child Activity and finishing child Activity.
