如何解决屏幕上的弹出窗口

Question

嗨在我的应用程序中，我想改变设备的调用者屏幕的外观和感觉，现在（我可能是错的）唯一的方法是调用弹出窗口在默认的android调用者屏幕上，因为你不能改变它。

我的弹出窗口出现时，用户按拨号，但然后它被默认的来电者屏幕取代，我的弹出窗口后面的默认调用者屏幕。

我该如何解决我的弹出窗口在屏幕上，以便它不被任何其他屏幕取代。

我DialerFragment.java：

发现这个代码，它使用广播Reciever 即时得到一个“无法解析变量为arg0和ARG1”错误任何想法如何清理？

// onReceive function of the Broadcast Receiver 
    public void onReceive(Context arg0, Intent arg1) { 
     String state = arg1.getStringExtra(TelephonyManager.EXTRA_STATE); 

     // Adds a view on top of the dialer app when it launches. 
     if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){ 
      wm = (WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE); 
      params1 = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.MATCH_PARENT, 
        WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT | 
        WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, 
        WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | 
          WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, 
        PixelFormat.TRANSPARENT); 

      params1.height = 75; 
      params1.width = 512; 
      params1.x = 265; 
      params1.y = 400; 
      params1.format = PixelFormat.TRANSLUCENT; 

      mLinearLayout = new LinearLayout(getContext()); 
      mLinearLayout.setBackgroundColor(Color.BLACK); 
      mLinearLayout.setOrientation(LinearLayout.VERTICAL); 

      wm.addView(mLinearLayout, params1); 
     } 

     // To remove the view once the dialer app is closed. 
     if(arg1.getAction().equals("android.intent.action.PHONE_STATE")){ 
      state = arg1.getStringExtra(TelephonyManager.EXTRA_STATE); 
      if(state.equals(TelephonyManager.EXTRA_STATE_IDLE)){ 
       WindowManager wm = (WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE); 
       if(mLinearLayout!=null) 
       { 
        wm.removeView(mLinearLayout); 
        mLinearLayout = null; 
       } 
      } 
     } 
    }
