一旦你将实际的字符串放入一个数组中，字符串将不会被刷新，直到你再次调用 getAllTv() 方法。我可以建议的最好的方法是不要存储实际的字符串，而是更改逻辑以存储字符串数组资源的资源 id 和数组中字符串的索引，然后在准备好显示之前不要创建实际的字符串它在您的 RecyclerView 适配器中。这样，您可以在语言更改时刷新 RecyclerView 适配器中的数据，并且它将从正确的字符串资源中提取字符串。

您可以使用 BroadCastReceiver 来检测区域设置以及通过关联语言何时更改和刷新您的数据集：

 BroadcastReceiver receiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            // refresh your adapter dataset and notify dataset changed here
        }

    };

    IntentFilter intentFilter = new IntentFilter(Intent.ACTION_LOCALE_CHANGED);
    registerReceiver(receiver, intentFilter);
