So, I tried putting a recyclerView in a "popup" dialog using a firebaseRecyclerAdapter. My problem is, that I know for sure the adapter gets filled because I was using the Logcat to tell me when it adds another "user" to the adapter, but it wont show anything in the recyclerview in the dialog.
I'm having this problem for a couple of days and couldn't find an answer yet, glad if you could help me :)
I'm using a main screen which changes fragments, and from a certain fragment I'm calling this specific dialog.
These are my files: UserViewHolder - the class which holds the "sets" for the cardview:
public static class UserViewHolder extends RecyclerView.ViewHolder
{
View mView;
public UserViewHolder(View itemView)
{
super(itemView);
mView=itemView;
}
public void setName(String name)
{
TextView teacherName=(TextView) mView.findViewById(R.id.txtNameTea);
teacherName.setText(name);
}
public void setEmail(String email)
{
TextView txtEmailTea=(TextView) mView.findViewById(R.id.txtEmailTea);
txtEmailTea.setText(email);
}
public void setImage(final Context ctx, Uri imageUri, User cUser)
{
final ImageView imgProfileTea=(ImageView) mView.findViewById(R.id.imgProfileTea);
Picasso.with(ctx).load(cUser.getImageUri()).into(imgProfileTea);
if(imgProfileTea.getDrawable()==null) {
StorageReference load = FirebaseStorage.getInstance().getReference().child("usersProfilePic/" + cUser.getImageName());
load.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
Picasso.with(ctx).load(uri.toString()).into(imgProfileTea);
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Toast.makeText(ctx, e.getMessage(), Toast.LENGTH_LONG);
}
});
}
}
}
Schedules - the fragment which calls the dialog from its toolbar:

One more thing is that I know is that I'm already able to bring up users into the recyclerView in other fragments.. Here's the code in another fragment:
package com.example.android.aln4;
import android.net.Uri;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Toast;
import com.firebase.ui.database.FirebaseRecyclerAdapter;
import com.google.firebase.database.FirebaseDatabase;
import com.google.firebase.storage.FirebaseStorage;
import static com.example.android.aln4.dataBase.mDatabaseReference;
import static com.example.android.aln4.dataBase.mFirebaseDatabase;
import static com.example.android.aln4.dataBase.mStorageRef;
import static com.example.android.aln4.navDrawerMain.firebaseRecyclerAdapter;
import static com.example.android.aln4.navDrawerMain.teachersQuery;
public class TeachersList extends Fragment {
private RecyclerView mRecyclerViewTeacher;
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
getActivity().setTitle("מורים");
mFirebaseDatabase = FirebaseDatabase.getInstance();
mDatabaseReference = mFirebaseDatabase.getReference("users");
mStorageRef = FirebaseStorage.getInstance().getReference();
mRecyclerViewTeacher=(RecyclerView) getView().findViewById(R.id.mRecyclerViewTeacher);
mRecyclerViewTeacher.setHasFixedSize(true);
mRecyclerViewTeacher.setLayoutManager(new LinearLayoutManager(getContext()));
setTeachersList();
}
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.teachers_list_frag,container,false);
}
private void setTeachersList() {
teachersQuery=mDatabaseReference.orderByChild("type").equalTo("Teacher");
firebaseRecyclerAdapter=new FirebaseRecyclerAdapter<User, navDrawerMain.UserViewHolder>(
User.class,R.layout.card_view_teacher,navDrawerMain.UserViewHolder.class,teachersQuery) {
@Override
protected void populateViewHolder(navDrawerMain.UserViewHolder viewHolder, User model, int position) {
viewHolder.setName(model.getFirstName()+" "+model.getLastName());
viewHolder.setEmail(model.getEmail());
viewHolder.setImage(getContext(), Uri.parse(model.getImageUri()),model);
}
};
mRecyclerViewTeacher.setAdapter(firebaseRecyclerAdapter);
}
}
and its xml file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/mRecyclerViewTeacher"
android:layout_marginTop="57dp"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
It's one of my first questions here so I apologize if I missed something :) Any help would be appriciated.
