ViewTreeObserver.OnWindowFocusChangeListener in a service

How to implement ViewTreeObserver.OnWindowFocusChangeListener in a service in Android . The code does not show any type of error when i use it in my java file . Is there any other way to use OnWindowFocusChangeListener in a service ? Please help me. Thanks in advance !!

Solution

  • Do it like this way 

    WindowManager windowManager=(WindowManager)getSystemService(WINDOW_SERVICE);
LayoutInflater inflater= 
(LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
RelativeLayout layout=(RelativeLayout) inflater.inflate(R.layout.box,null);

    You need a WindowManager.LayoutParams object which should contain the parameters for the layout

    windowManager.addView(layout,params);

    now add ViewTreeObserver.OnWindowFocusChangeListener on your desired view.
