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。
