[Android]如何获取设备真实尺寸

    private static Point getPhysicalScreenSize(Context context){
        Point p = new Point();
        DisplayManager dm = (DisplayManager) context.getSystemService(Context.DISPLAY_SERVICE);
        Display[] displays = dm.getDisplays();
        int maxWidth = -1, maxHeight = -1;
        DisplayMetrics met = new DisplayMetrics();
        for(Display d : displays){
            d.getMetrics(met);
            maxWidth = met.widthPixels > maxWidth ? met.widthPixels : maxWidth;
            maxHeight = met.heightPixels > maxHeight ? met.heightPixels : maxHeight;
        }
        p.x = maxWidth;
        p.y = maxHeight;
        return p;
    }
