当我尝试绑定数据时，模拟器中只显示进度。但是在Logcat中，每件事都很好
我的基地FirebaseRecyclerAdapter：
public abstract class FirestoreAdapter<VH extends RecyclerView.ViewHolder> extends RecyclerView.Adapter<VH> implements EventListener<QuerySnapshot> {
private static final String TAG = "Firestore Adapter";
private Query mQuery;
private ListenerRegistration mRegistration;
protected ArrayList<DocumentSnapshot> mSnapshots = new ArrayList<>();
public FirestoreAdapter(Query query) {
mQuery = query;
}
@Override
public void onEvent(QuerySnapshot documentSnapshots, FirebaseFirestoreException e) {
if (e != null) {
Log.w(TAG, "onEvent:error", e);
onError(e);
return;
}
// Dispatch the event
Log.d(TAG, "onEvent:numChanges:" + documentSnapshots.getDocumentChanges().size());
for (DocumentChange change : documentSnapshots.getDocumentChanges()) {
switch (change.getType()) {
case ADDED:
onDocumentAdded(change);
break;
case MODIFIED:
onDocumentModified(change);
break;
case REMOVED:
onDocumentRemoved(change);
break;
}
}
onDataChanged();
}
public void startListening() {
if (mQuery != null && mRegistration == null) {
mRegistration = mQuery.addSnapshotListener(this);
}
}
public void stopListening() {
if (mRegistration != null) {
mRegistration.remove();
mRegistration = null;
}
mSnapshots.clear();
notifyDataSetChanged();
}
public void setQuery(Query query) {
// Stop listening
stopListening();
// Clear existing data
mSnapshots.clear();
notifyDataSetChanged();
// Listen to new query
mQuery = query;
startListening();
}
@Override
public int getItemCount() {
return mSnapshots.size();
}
public DocumentSnapshot getSnapshot(int index) {
return mSnapshots.get(index);
}
protected void onDocumentAdded(DocumentChange change) {
mSnapshots.add(change.getNewIndex(), change.getDocument());
notifyItemInserted(change.getNewIndex());
}
protected void onDocumentModified(DocumentChange change) {
if (change.getOldIndex() == change.getNewIndex()) {
// Item changed but remained in same position
mSnapshots.set(change.getOldIndex(), change.getDocument());
notifyItemChanged(change.getOldIndex());
} else {
// Item changed and changed position
mSnapshots.remove(change.getOldIndex());
mSnapshots.add(change.getNewIndex(), change.getDocument());
notifyItemMoved(change.getOldIndex(), change.getNewIndex());
}
}
protected void onDocumentRemoved(DocumentChange change) {
mSnapshots.remove(change.getOldIndex());
notifyItemRemoved(change.getOldIndex());
}
protected void onError(FirebaseFirestoreException e) {

用于查询的基本Firestore适配器：
CustomRecycler适配器：
public class Bidhaa_Recycler_Adapter extends FirestoreAdapter{

case BIDHAA_VIEW_TYPE:

}
}
@Override

switch (itemViewType){

}
adCardView.addView(adView);
break;
case BIDHAA_VIEW_TYPE:
default:
Bidhaa_Holder bidhaaHolder = (Bidhaa_Holder) holder;
//Bidhaa_Data bidhaaData = (Bidhaa_Data) mSnapshots.get(position);
bidhaaHolder.BindData(getSnapshot(itemViewType));
//((Bidhaa_Holder) holder).BindData(getSnapshot(position));
}
}
@Override
public int getItemCount() {

}
@Override
public int getItemViewType(int position) {
return (position % 2 == 0) ? NATIVE_EXPRESS_AD_VIEW_TYPE : BIDHAA_VIEW_TYPE;
}
@Override
public void onEvent(Object o, FirebaseFirestoreException e) {

}
First View Holder
Bidhaa ViewHolder：
