Android back button does not work while playing video in VideoView

Question

The Android back button does not work during video playback in VideoView. But it works before playing the video. I use a special MediaController for VideoView.
I tried using dispatchKeyEvent , its not working.

Action code using VideoView:

mc = new CustomMediaController(mVideo.getContext(), screenIcon) { @Override public void hide(){ } @Override public boolean dispatchKeyEvent(KeyEvent event){ if (event.getKeyCode() == KeyEvent.KEYCODE_BACK) { super.hide(); ((Activity) getContext()).finish(); return true; } return super.dispatchKeyEvent(event); } }; 

 @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_BACK)) { onBackPressed(); finish(); } return true; } @Override public void onBackPressed() { super.onBackPressed(); finish(); } 

CustomMediaController also contains dispatchKeyEvent:

 @Override public boolean dispatchKeyEvent(KeyEvent event) { if (event.getKeyCode() == KeyEvent.KEYCODE_BACK) { ((Activity) getContext()).finish(); } return super.dispatchKeyEvent(event); } 

Also, when I view the layout, mediaController did not save its position in the videoView. To fix this error, I added code to correct the position of the mediaController.

 FrameLayout f; RelativeLayout.LayoutParams lp; RelativeLayout.LayoutParams params; params = (RelativeLayout.LayoutParams) mVideo.getLayoutParams(); params.height = mp.getVideoHeight(); progress.dismiss(); f = (FrameLayout) mc.getParent(); lp = new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT); lp.addRule(RelativeLayout.ALIGN_BOTTOM, mVideo.getId()); try { ((LinearLayout) f.getParent()).removeView(f); } catch (Exception e) { ((RelativeLayout) f.getParent()).removeView(f); } ((RelativeLayout) mVideo.getParent()).addView(f, lp); //mc.setAnchorView(mVideo); mVideo.setLayoutParams(params);

Back works fine when I delete this code above.

I addressed the following issues in stack overflow, but did not solve the problem.
