我想为我的应用程序添加一个自定义视图.为此,我使用WindowsManager：

        final WindowManager wm = getWindowManager();
        final View view = ((LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.game_menu, null);
        WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
        lp.flags |= WindowManager.LayoutParams.FLAG_DIM_BEHIND | WindowManager.LayoutParams.FLAG_FULLSCREEN;
        lp.dimAmount = (float) 0.6;
        lp.format = PixelFormat.TRANSPARENT;
        lp.windowAnimations = android.R.style.Animation_Dialog;
        view.setOnKeyListener(new OnKeyListener() 
        {
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event) 
            {
                Log.d("12", "12");
                if (keyCode == KeyEvent.KEYCODE_BACK)
                {
                    wm.removeView(view); // This I need to hide my menu
                }
                return false;
            }
        });
        wm.addView(view, lp); // I add menu like in Angry Birds and other games

但是我无法捕获用于隐藏此视图的设备按键事件.

为什么在WindowsManager添加的视图中未调用我的密钥侦听器？如何通过按下设备后退键隐藏我的视图？

解决方法:

您可以添加这些setFocusableInTouchMode(true);在你看来
