[Android] 动态语言切换

直接上代码：

public static void updateLocale(Context context, Locale locale) {
        Resources resources = context.getResources();
        Configuration configuration = resources.getConfiguration();
        if (configuration.locale.equals(locale))
            return;

        DisplayMetrics displayMetrics = resources.getDisplayMetrics();
        configuration.locale = locale;
        resources.updateConfiguration(configuration, displayMetrics);
        Resources.getSystem().updateConfiguration(configuration, displayMetrics);
    }
