Google Maps Android API v2使GoogleMap View动画

Question

I am trying to animate that wraps the Google Maps Fragment in my layout. The following animation appears to have no effect.

ObjectAnimator mapAnimator = ObjectAnimator.ofFloat(view, "translationY", -view.getHeight(), view.getHeight());

I have tried wrapping the fragment in FrameLayout and animating that with no luck. I can only seem to hide and show the map with the FragmentManager.

According to this issue the Google Map uses a SurfaceView which can't be animated. I cannot find anything official to support this. Can anyone confirm?

Answer 1

I cannot find anything official to support this.

If "this" means the fact that Maps V2 uses SurfaceView , drop a ViewServer in your app , hook up Hierarchy View to your app running on a Maps V2-capable device, and see what you see. Cyril Mottier wrote comment #1 on the issue you cited; since he says it is a SurfaceView , I believe him.

If "this" means the fact that SurfaceView cannot be animated, that is confirmed by reading the documentation for TextureView .
