Error getting window size on android: “The method getWindowManager is undefined”

Question

I need to get the window height and the weight.
I have this in my code:

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDispl         


        

Answer 1

Where are you using this code?

The error of the getWindowManager says that cannot find the method because the root of your class doesn't have it.

Try this:

((Activity) getContext()).getWindowManager().getDefaultDisplay().getMetrics(metrics);

or

((WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE))
  .getDefaultDisplay().getMetrics(metrics);

If this doesn't work, please paste your activity
