Question

在找到一些人说FirebaseRecyclerAdapters在片段内部被破坏（并且在此之前尝试了大约4个小时才能使其工作）之后，我决定切换到FirebaseListAdapter，因为我发现在片段内工作的例子。但是，我遇到了问题。 populateView()方法似乎永远不会被触发，我没有错误。这是片段的代码：

public class PasteFromFirebasePopup extends DialogFragment implements AdapterView.OnClickListener {
Activity activity;

private FirebaseListAdapter mFirebaseAdapter;
private DatabaseReference mClipboardHistoryReference;
private ListView mListView;

public PasteFromFirebasePopup() {}

@Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container,
                                   Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.clip_history_popup_list, container, false);

    mListView = (ListView) rootView.findViewById(R.id.clipboardHistoryListView);

    activity = getActivity();
    mClipboardHistoryReference = FirebaseDatabase.getInstance().getReference(Constants.FIREBASE_CHILD_CLIPBOARD_HISTORY);
    Log.d("clipboardRef", mClipboardHistoryReference.toString());

    mFirebaseAdapter = new FirebaseListAdapter<FirebaseString>
            (activity, FirebaseString.class, R.layout.clip_history_popup_item, mClipboardHistoryReference) {
            TextView mTextView;

        @Override protected void populateView(View v, FirebaseString model, int position) {

            mTextView = (TextView) v.findViewById(R.id.clipboardHistoryTextView);
            Log.d("model text", model.getText());
            mTextView.setText(model.getText());
        }
    };

    mListView.setAdapter(mFirebaseAdapter);

    return rootView;
}

@Override public void onClick(View v) {}

@Override public void onDestroy() {
    super.onDestroy();
    mFirebaseAdapter.cleanup();
}

}

无论我尝试什么，populateView()内的日志绝对不会触发。我已经三次检查了我的参考，并且确实有一些东西（目前只有一个项目，但据我所知，这不重要）。我错过了什么吗？这在DialogFragments内部不起作用吗？如果没有，是否有人建议popup可以成功保留FirebaseListAdapter/RecyclerAdapter？

任何帮助都得到了适当的赞赏。

编辑：我的build.gradle (app)，因为我认为这可能与它有关。

FirebaseListAdapter没有触发populateView（）
