ConnectivityManager.OnNetworkActiveListener WI-FI问题

Question

我在ConnectivityManager.OnNetworkActiveListener界面上遇到问题，调用了移动数据onNetworkActive()方法，但是当我用 WI-FI 测试它时，没有调用此方法。

我在做什么错？ android是否应具有监视WIFI网络连接的权限才能解决此问题？

    @Override
public void onNetworkActive() {
    Log.d(TAG, "onNetworkActive: called");
    if (photos == null || photos.size() < 1) {
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
        String queryResult = sharedPreferences.getString(FLICKR_QUERY, "");

        if (queryResult.length() > 0) {
            GetFlickrJsonData getFlickrJsonData = new GetFlickrJsonData("https://api.flickr.com/services/feeds/photos_public.gne", "en-us", true, this);
            getFlickrJsonData.execute(queryResult);
        }
    }
}
