How to get screen width and height

Question

I tried to use following code to get screen width and height in android app development:

Display display = getWindowManager().getDefaultDisplay(); 
int scree         


        

Answer 1

Alternative way using function

private int[] getScreenSIze(){
        DisplayMetrics displaymetrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        int h = displaymetrics.heightPixels;
        int w = displaymetrics.widthPixels;

        int[] size={w,h};
        return size;

    }

on button click or on your create function add the following code

int[] screenSize= getScreenSIze();
        int width=screenSize[0];
        int height=screenSize[1];
        screenSizes.setText("Phone Screen sizes \n\n  width = "+width+" \n Height = "+height);
