Android get display size

  If you want the the display dimensions in pixels you can use getSize:

Display display = getWindowManager().getDefaultDisplay();

Point size = new Point();

display.getSize(size);

int width = size.x;

int height = size.y;

  If you're not in an Activity you can get the default Display via WINDOW_SERVICE:

WindowManager wm = (WindowManager) ctx.getSystemService(Context.WINDOW_SERVICE);

Display display = wm.getDefaultDisplay();

  Before getSize was introduced (in API level 13), you could use the getWidth and getHeight methods that are now deprecated:

Display display = getWindowManager().getDefaultDisplay(); 

int width = display.getWidth();  // deprecated

int height = display.getHeight();  // deprecated

  For the use case you're describing however a margin/padding in the layout seems more appropriate.
