从服务块触摸

Question

有没有办法阻止从服务的任何应用程序的触摸？我一直在想getWindow()，但这在服务中是不可能的。此外，我一直在考虑获取当前活动，然后使用getWindow()。我希望你明白我试图达成的目标。

感谢David Medenjak我设法解决了这个问题。该解决方案正在研究23以下的Android API，并且它将使屏幕变黑并阻止触摸，直到您在屏幕上长按。

 WindowManager windowManager = (WindowManager) getSystemService(WINDOW_SERVICE); 

     ImageView black = new ImageView(this); 
     black.setImageResource(R.drawable.black); 

     WindowManager.LayoutParams params = new  WindowManager.LayoutParams(
       WindowManager.LayoutParams.MATCH_PARENT, 
       WindowManager.LayoutParams.MATCH_PARENT, 
       WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, 
       WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | 
         WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, 
       PixelFormat.TRANSLUCENT); 

     params.gravity = Gravity.TOP | Gravity.LEFT; 
     params.x = 0; 
     params.y = 0; 

     windowManager.addView(black, params); 

     black.getLayoutParams().height = windowManager.getDefaultDisplay().getHeight(); 
     black.getLayoutParams().width = windowManager.getDefaultDisplay().getWidth(); 

     black.setOnLongClickListener(new View.OnLongClickListener() { 
      @Override 
      public boolean onLongClick(View v) { 
       return false; 
      } 
     });
