I\'ve add a View, by using WindowManager.
It shows properly what I wanted to do,
but I have a problem. this is the problem.
Override dispatchKeyEvent of your View
@Override public boolean dispatchKeyEvent(KeyEvent event) { if (event.getKeyCode() == KeyEvent.KEYCODE_BACK) { // handle back press // if (event.getAction() == KeyEvent.ACTION_DOWN) return true; } return super.dispatchKeyEvent(event); }
