クリップ:

  wm = (WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE);

  // muteFlag = true;
  WindowManager.LayoutParams params = new WindowManager.LayoutParams();
  params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;
  params.width = WindowManager.LayoutParams.WRAP_CONTENT;
  params.height = WindowManager.LayoutParams.WRAP_CONTENT;
  params.format = PixelFormat.RGBA_8888;
  params.gravity = Gravity.TOP | Gravity.LEFT;
  params.x = 85;
  params.y = 25;
  LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  muteView = inflater.inflate(R.layout.mute, null); 
  wm.addView(muteView, params);

 mute.xmlはlayoutファイルです
