android gets the screen size

Without further ado, I'll just hand in the code

DisplayMetrics dm = new DisplayMetrics();

                getWindowManager().getDefaultDisplay().getMetrics(dm);

                int width = dm.widthPixels;  //  Screen width (pixels) 

                int height = dm.heightPixels;  //  Screen height (pixels) 

                Toast.makeText(this,  width+":"+height, Toast.LENGTH_LONG).show();

Above is the code that this article shares to you, hope you can like.
