display getSize()
编辑：rootadminIf 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 ), 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
