本文实例讲述了Android编程实现获得手机屏幕真实宽高的方法。分享给大家供大家参考，具体如下：

WindowManager w = activity.getWindowManager();Display d = w.getDefaultDisplay();DisplayMetrics metrics = new DisplayMetrics();d.getMetrics(metrics);// since SDK_INT = 1;widthPixels = metrics.widthPixels;heightPixels = metrics.heightPixels;try {  // used when 17 > SDK_INT >= 14; includes window decorations (statusbar bar/menu bar)  widthPixels = (Integer) Display.class.getMethod("getRawWidth").invoke(d);  heightPixels = (Integer) Display.class.getMethod("getRawHeight").invoke(d);} catch (Exception ignored) {}try {  // used when SDK_INT >= 17; includes window decorations (statusbar bar/menu bar)  Point realSize = new Point();  Display.class.getMethod("getRealSize", Point.class).invoke(d, realSize);  widthPixels = realSize.x;  heightPixels = realSize.y;} catch (Exception ignored) {}

补:改进版 (弥补了原先非支持版本的一些异常):

WindowManager w = activity.getWindowManager();Display d = w.getDefaultDisplay();DisplayMetrics metrics = new DisplayMetrics();d.getMetrics(metrics);// since SDK_INT = 1;widthPixels = metrics.widthPixels;heightPixels = metrics.heightPixels;// includes window decorations (statusbar bar/menu bar)if (Build.VERSION.SDK_INT >= 14 && Build.VERSION.SDK_INT < 17)try {  widthPixels = (Integer) Display.class.getMethod("getRawWidth").invoke(d);  heightPixels = (Integer) Display.class.getMethod("getRawHeight").invoke(d);} catch (Exception ignored) {}// includes window decorations (statusbar bar/menu bar)if (Build.VERSION.SDK_INT >= 17)try {  Point realSize = new Point();  Display.class.getMethod("getRealSize", Point.class).invoke(d, realSize);  widthPixels = realSize.x;  heightPixels = realSize.y;} catch (Exception ignored) {}

希望本文所述对大家Android程序设计有所帮助。
