Android 获取屏幕宽高值

note：单位为像素。

三个方法中都是根据Display来进行测量。

//方法一：
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
        Display display = wm.getDefaultDisplay();
        int width = display.getWidth();
        int height = display.getHeight();
        System.out.println("width = " + width + " , height = " + height);

//方法二：也可以获取到屏幕的密度density
 DisplayMetrics metrics = new DisplayMetrics();
        ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay().getMetrics(metrics);
        int widthPixels = metrics.widthPixels;
        int heightPixels = metrics.heightPixels;
        System.out.println("width = " + widthPixels + " , height = " + heightPixels);

//方法三：
WindowManager wm = (WindowManager)getSystemService(WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
Point point = new Point();
display.getSize(point);
int width = point.x;
int height = point.y;
System.out.println("width = " + width + " , height = " + height);
