Android, How to set animation listener for view group?

Question

I have an image view which acts as menu. When user click it a view group (including 5 other image view) will slide from left to right. When user click on menu again view group slides from right to left.

I can simulate this behavior but after sliding right to left I expect to not see view group however view group will put on its place. I tried to use LinearLayout.setVisibiliy(View.Invisible) but at that moment i couldn't see sliding right to left animation.

This is my code, any suggestion would be appreciated.

menu_open.xml

<layoutAnimation 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:delay="10%"
    android:animation="@anim/slide_out" />

slide_out.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">

    <translate 
        android:fromXDelta="-100%p" 
        android:toXDelta="0"
        android:duration="@android:integer/config_mediumAnimTime" />

    <alpha 
        android:fromAlpha="0.0" 
        android:toAlpha="1.0"
        android:duration="@android:integer/config_mediumAnimTime" />
</set>

menu_close.xml

<layoutAnimation 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:delay="10%"
    android:animation="@anim/slide_in" />

slide_in.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" >

Finally I found the solution. In this case we should use aViewGroup.setLayoutAnimationListener(new AnimationListener()...) and override its methods.

Therefore I added:

 groupLayout.setLayoutAnimationListener(new AnimationListener() {

            @Override
            public void onAnimationStart(Animation animation) {}

            @Override
            public void onAnimationRepeat(Animation animation) {}

            @Override
            public void onAnimationEnd(Animation animation) {
                if(menuState)
                    groupLayout.setVisibility(View.INVISIBLE);

                menuState = !menuState;
                Log.i("Menu state", "" + menuState);
            }
        });
