获取手机屏幕尺寸的代码段[转自eoeandroid]

来个获取屏幕尺寸的代码，希望有人用的上：

 

 1        public static String getDisplayMetrics(Context cx) {
 2                String str = "";
 3                DisplayMetrics dm = new DisplayMetrics();
 4                dm = cx.getApplicationContext().getResources().getDisplayMetrics();
 5                int screenWidth = dm.widthPixels;
 6                int screenHeight = dm.heightPixels;
 7                float density = dm.density;
 8                float xdpi = dm.xdpi;
 9                float ydpi = dm.ydpi;
10                str += "The absolute width:" + String.valueOf(screenWidth) + "pixels\n";
11                str += "The absolute heightin:" + String.valueOf(screenHeight)
12                                + "pixels\n";
13                str += "The logical density of the display.:" + String.valueOf(density)
14                                + "\n";
15                str += "X dimension :" + String.valueOf(xdpi) + "pixels per inch\n";
16                str += "Y dimension :" + String.valueOf(ydpi) + "pixels per inch\n";
17                return str;
18        }
