Android开发中如何获取屏幕宽高

Posted 2021-07-17 我想月薪过万

• 方法一

        WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
        DisplayMetrics metrics = new DisplayMetrics();
        wm.getDefaultDisplay().getMetrics(metrics);
        int mScreenHeight = metrics.heightPixels;
        int mScreenWidth = metrics.widthPixels;
        System.out.println("mScreenHeight ->" + mScreenHeight + "mScreenWidth ->" + mScreenWidth);

• 方法二（该方法被废弃了，不推荐使用）

        int mScreenHeight3 = wm.getDefaultDisplay().getHeight();
        int mScreenWidth3 = wm.getDefaultDisplay().getWidth();
        System.out.println("mScreenHeight3 ->" + mScreenHeight3 + "mScreenWidth3 ->" + mScreenWidth3);   

• 方法三

        Point point = new Point();
        wm.getDefaultDisplay().getSize(point);
        int mScreenHeight4 = point.y;
        int mScreenWidth4 = point.x;
        System.out.println("mScreenHeight4 ->" + mScreenHeight4 + "mScreenWidth4 ->" + mScreenWidth4);

• 方法四

        Resources rs = getResources();
        DisplayMetrics dm = rs.getDisplayMetrics();
        int mScreenHeight2 = dm.heightPixels;
        int mScreenWidth2 = dm.widthPixels;
        System.out.println("mScreenHeight2 ->" + mScreenHeight2 + "mScreenWidth2 ->" + mScreenWidth2);
