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

Use the Context of the activity with getActivityContext()

DisplayMetrics metrics = new DisplayMetrics();
getActivityContext().getWindowManager().getDefaultDisplay().getMetrics(metrics);
width1 = metrics.widthPixels; 
height1 = metrics.heightPixels;
