索尼 bravia tv 中 Surfaceview 高于另一个 Surfaceview 交换时的问题

Question

In my sample i need to swap big player and small player when clicking swap button but small player above big player is not visible, i am setting elevation for container for the each fragment when doing swap but this does not seems like working with surfaceview but with textureview it is working,

i have tried fix which mentioned in here

but that fix does not work for Sony Bravia TV.

Answer 1

A SurfaceView is "just an hole" where Android renders the Surface, so it depends of Order or Creation. If you Attach_to_window the BIG SurfaceView before the SMALL one, then the second will stay over the first and there isn't any method to change this order for this Special kind of View (Android references reports that SurfaceView cannot be managed as a normal View which supports all transformations).

The only secure solution is to Detach both SurfaceViews and then re-attach them in the right order (or just swap internal Render Threads Canvas/Surface target if you're using Render Threads).
