Romain,
Thank you for the suggestion. I just tried but rotation still starts
before GridView completes.
Correct me if I misunderstand but here is what may happen:
In GridView, a layoutAnimation is used. This
LayoutAnimationController in turns specifies animation for each child
view.
So what I need is an "onAnimationEnd" for LayoutAnimationController -
which should be "isDone()" based on API documentation.
##--
I applied Listener onAnimationEnd as follow:
LayoutAnimationController animControl = mImageView.getLayoutAnimation
();
...
Animation anim = animControl.getAnimation() // or getAnimationForView
(...);
anim.setAnimationListener(this);
,,,
The "anim" here is individual child view, instead of the entire
GridView whose completion is what I need.
Now if I count how many times onAnimationEnd is called & when count
reaches my child view count,
I can apply the 2nd animation. But that amounts to implementing my own
"isDone()" with hard coded child view count.
##---------------------------------------------------------------
In GridView, I specified a layoutAnimation (not android:anim which
appears in layout_random_fade):
<FrameLayout .../>
<GridView
android:layoutAnimation="@anim/layout_random_fade" <--
android:anim in layout_random_fade
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
<TextView
...
/>
