android之获取屏幕的宽度和高度

获取屏幕的宽度和高度：

方法一:

        //获取屏幕的宽度
	public static int getScreenWidth(Context context) {
		WindowManager manager = (WindowManager) context
				.getSystemService(Context.WINDOW_SERVICE);
		Display display = manager.getDefaultDisplay();
		return display.getWidth();
	}
	//获取屏幕的高度
	public static int getScreenHeight(Context context) {
		WindowManager manager = (WindowManager) context
				.getSystemService(Context.WINDOW_SERVICE);
		Display display = manager.getDefaultDisplay();
		return display.getHeight();
	}

 方法二：

DisplayMetrics  dm = new DisplayMetrics();    

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

int screenWidth = dm.widthPixels;              

int screenHeight = dm.heightPixels;
