Why doesn't popwindow display content when recyclerview is nested?

1.popwindow nests recyclerview, but does not display content

2. The related code is as follows:
popwindow layout xml--

< FrameLayout xmlns:android= "http://schemas.android.com/apk/res/android"

android:id="@+id/fl_familyList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignTop="@+id/rl_family"
android:background="@color/colorRlBg">

<RelativeLayout
    android:id="@+id/ly_family_list"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/rv_mfamily_list"
            android:layout_width="match_parent"
            android:layout_height="200dp">
        </android.support.v7.widget.RecyclerView><!---->


 </RelativeLayout>

< / FrameLayout >

adapter code--
public class RvFamilyAdapter extends RecyclerView.Adapter < RvFamilyAdapter.ViewHolder > {

private List<Family> mfamilyList;

public RvFamilyAdapter(List<Family> familyList) {
    mfamilyList = familyList;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    //RecyclerViewitem.xml
    View view = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.family_familylist_recyclerview_item, parent, false);
    ViewHolder holder = new ViewHolder(view);
    return holder;
}

@Override
public void onBindViewHolder(@NonNull RvFamilyAdapter.ViewHolder holder, int position) {
    //positionIntelligent
    //viewfamily
    holder.tv_family_name.setText(mfamilyList.get(position).getFamilyName());
    holder.tv_family_owner_name.setText(mfamilyList.get(position).getFamilyOwner());
}

@Override
public int getItemCount() {
    return mfamilyList.size();
}
/*ViewHolder*/
static class ViewHolder extends RecyclerView.ViewHolder {
    ImageView iv_family_is_true;
    ImageView iv_family_logo;
    TextView tv_family_name;
    TextView tv_family_character;
    TextView tv_family_owner_name;
    /*
     *  ViewHolderview
     * */
     ViewHolder(View itemView) {
        super(itemView);
        //viewActivityitemViewfind
        iv_family_is_true = itemView.findViewById(R.id.iv_family_is_true);
        iv_family_logo = itemView.findViewById(R.id.iv_family_logo);
        tv_family_name = itemView.findViewById(R.id.tv_family_name);
        tv_family_character = itemView.findViewById(R.id.tv_family_character);
        tv_family_owner_name = itemView.findViewById(R.id.tv_family_owner_name);
    }
}

}

bind adapter:--
private void handRecyList () {

    View view = LayoutInflater.from(getActivity()).inflate(R.layout.family_popwindow_view,null);
    RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.rv_mfamily_list);
    LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
    linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
    recyclerView.setLayoutManager(linearLayoutManager);
    family_adapter = new RvFamilyAdapter(getFamilyList());
    recyclerView.setAdapter(family_adapter);
    family_adapter.notifyDataSetChanged();
}

3. Error message: RecyclerView: No adapter attached; skipping layout

4. I have tried many methods, such as changing linear layout to relative layout, setadapter at initialization, updating data source family_adapter.notifyDataSetChanged (), clean&&rebuild.. I can"t find out the reason all the time. Is it because I put popwindow in fragment? I have been looking for the reason for a week. I would appreciate it if you would like to ask the gods to help me.

I have a few questions for you. Is
1.recyclerview in popwindows?
2. Do you mean that the contents of the list can't be displayed, or that popwindow doesn't pop up at all?

do you have no
