[android-developers] Unexpected behavior with animated views / layouts
I am using a button to trigger an animation of a view. This button
toggles the view, such that the view slides on and off the screen...
Class Members:
final Animation animout = AnimationUtils.loadAnimation(this,
R.anim.slideout );
final Animation animin = AnimationUtils.loadAnimation(this,
R.anim.slidein );
Click handler for the button:
public void onClick(View v)
{
View sv = findViewById(R.id.SV);
if(mDialIsIn)
{
sv.clearAnimation();
sv.startAnimation(animout);
mDialIsIn = false;
}
else
{
sv.clearAnimation();
sv.startAnimation(animin);
mDialIsIn = true;
}
}
So... it works... but...
This view that is moving around has a handler for the touch event. The
strange thing is... when my view is off screen, it is still getting
touch events for its original position on screen. It seems the
animation is only moving the visual aspect of the view (drawing
surface) and not the rest of the view's guts.
Does this make sense?
Do I just need to manually turn off my handling of the touch event
while the view is animated off screen?
And...
My intention was to put other controls UNDER this view. If this view
is on top receiving touch events even when off screen, will controls
underneath get their events? Or... do I have to do something about the
Z order when the view is scrolled off screen?
Am I just going about this all wrong?
Thanks,
Buzz

Yes, AFAIK, that's how it works (I haven't actually used Animations yet). Animations make it look like the views are doing something, they're not actually doing anything. You need to update the layout once the view is done animating to make stick. - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Unexpected behavior with animated views / layouts
The views definentally don't update when you want them too, and it does this to save cpu, there is something in the documention that updates the view, im not sure if it will work with this. But you probably should disable the button when it is off screen.
