Re: [android-developers] Re: SurfaceView#setZOrderMediaOverlay(true) not working as expected
I though z-order of SurfaceViews is nothing to do(and not guaranted) with order of layout.addView(SurfaceView). but this seems to have something to do with the order of the addView(). For example, // v2 should be on top of v1 SurfaceView v1; GLSurfaceView v2; // Case 1 : always v2 is on top of v1 v2.setZOrderMediaOverlay(true) parent.addView(v1); parent.addView(v2); // Case 2 : sometimes v2 is on top of v1 v2.setZOrderMediaOverlay(true) parent.addView(v2); parent.addView(v1); Does setZOrderMediaOverlay(true) only works if it is the last child? 2011년 9월 8일 목요일 오전 3시 29분 22초 UTC+9, Dianne Hackborn 님의 말: This is used by the standard launcher for its apps list, so it works correctly.
