Android利用Java反射机制修改Android System Language

private void updateLanguage(Locale locale) {
        try {
            Object objIActMag, objActMagNative;
            Class clzIActMag = Class.forName("android.app.IActivityManager");
            Class clzActMagNative = Class.forName("android.app.ActivityManagerNative");
            Method mtdActMagNative$getDefault = clzActMagNative.getDeclaredMethod("getDefault");
            // IActivityManager iActMag = ActivityManagerNative.getDefault();
            objIActMag = mtdActMagNative$getDefault.invoke(clzActMagNative);
            // Configuration config = iActMag.getConfiguration();
            Method mtdIActMag$getConfiguration = clzIActMag.getDeclaredMethod("getConfiguration");
            Configuration config = (Configuration) mtdIActMag$getConfiguration.invoke(objIActMag);
            config.locale = locale;
            // iActMag.updateConfiguration(config);
            // 此处需要声明权限:android.permission.CHANGE_CONFIGURATION
            // 会重新调用 onCreate();
            Class[] clzParams = { Configuration.class };
            Method mtdIActMag$updateConfiguration = clzIActMag.getDeclaredMethod(
                    "updateConfiguration", clzParams);
            mtdIActMag$updateConfiguration.invoke(objIActMag, config);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
