Android RecyclerView only display one item

Android RecyclerView only display one item - android

I tried other answers but nothing worked. for some reason RecyclerView only displaying one item. I tried changing layout height to wrap content but it didn't worked, still displaying only one item. I'm passing about 20 items.
I have to type more otherwise stackoverflow won't let me post this question. because it mostly code

check getItemCount() in your FeedAdapter.
it's must look like this:
#Override
public int getItemCount() {
return feed.size();

When we add listener Android create a separate thread for that and that thread run separately. So in your case we you are adding the listener android is creating the separate thread for that and then it immediately set the adapter for the recyclerView.
Create the adapter before adding the listener and set the adapter with recyclerView in the onDataChanged( ) method after the for loop.
#Override
public void onDataChange(#NonNull DataSnapshot dataSnapshot) {
usrs.clear();
for(DataSnapshot child:dataSnapshot.getChildren())
{
//String id=child.getKey();

firebaseRecyclerAdapter gets filled, yet wont show anything in a dialog - Android Studio

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.

Solved. All I did was regenerating the SHA1 in the firebase settings, and removing the setHasFixedSize line from Schedules activity and it worked just fine.

Integrating Tap Research sdk on Android

I integrated Tap Research sdk on my Android app, but application getting force stop.
Any idea why this might be happening?
This is my code tapresearchactivity.java
import android.app.Activity;
import android.app.Application;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ProgressBar;
import android.widget.Toast;
import com.tapr.sdk.TapResearch;
import com.tapr.sdk.TapResearchOnRewardListener;
class MyApp extends Application {
final private String YOUR_API_TOKEN = "fa7dbeeacebe7ae3e0b24e8dccaa6acb";
public class onCreate{} {
super.onCreate();
TapResearch.configure(YOUR_API_TOKEN, this);
}
}
public class TapresearchActivity extends Activity {
private Button show_button;
#Override
protected void onCreate(Bundle bundle) {
super.onCreate(bundle);
setContentView(R.layout.activity_tapresearch);
/** Set up button to show an ad when clicked */
show_button = (Button) findViewById(R.id.showbutton);
if (TapResearch.getInstance().isSurveyAvailable()) {
show_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
TapResearch.getInstance().showSurvey();
}
});
}
}
}
And this is my xml layout file here activity_tapreserch.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".TapresearchActivity">
<Button
android:layout_width="298dp"
android:layout_height="68dp"
android:enabled="false"
android:id="#+id/showbutton"
android:background="#drawable/button_blue"
android:layout_alignParentBottom="true"
android:layout_marginBottom="10dp"
android:layout_centerHorizontal="true"/>
</RelativeLayout>
