Try via context.getResources().getDisplayMetrics() if you have a context available.

Display display = getActivity().getWindowManager().getDefaultDisplay(); 
int screenWidth = display.getWidth();
int screenHeight = display.getHeight();
Log.d("Tag", "Getting Width >> " + screenWidth);
Log.d("Tag", "Getting Height >> " + screenHeight);

This worked properly in my application
