Your question is not that clear. Please add some more details like what is you want, what you have implemented and what issue is coming.
You may also try my implementation. I am not using Recycler view in my implementation, but you could follow the following article I wrote for integrating Dialogflow with Android. Try an follow the V2 version as V1 will phase out by October this year.
Also, Do not use fragment for Chatbot as it somehow does not work. Try and make a simple chatbot using my implementation and then you can work towards your own implementation.
Hope it works.

I tried the solutions on the other similar posts that I found here but they did not help me. I hope someone can help.
I get data from Unsplash's API and the ArrayList contains 10 items once I get a response, that's why I think It has to be something with the way the view is inflated.
This is code:
public class MainActivity extends AppCompatActivity {
private static final String TAG = "unsplash";
private final String CLIENT_ID = "...myclientID...";
// testing keyword used on the API to search for pictures
private final String KEYWORD = "stackOverflow";
private final String urlBase = "https://api.unsplash.com/";
private Retrofit retrofit;
private RecyclerView recyclerView;
private RecyclerViewAdapter recyclerViewAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
retrofit = new Retrofit.Builder()
.baseUrl(urlBase)
.addConverterFactory(GsonConverterFactory.create())
.build();
recyclerView = findViewById(R.id.recyclerview);
recyclerView.setHasFixedSize(true);
GridLayoutManager layoutManager = new GridLayoutManager(this, 2);
recyclerView.setLayoutManager(layoutManager);
recyclerViewAdapter = new RecyclerViewAdapter();
recyclerView.setAdapter(recyclerViewAdapter);
getData();
}
private void getData() {
PictureService service = retrofit.create(PictureService.class);
Call<PictureResponse> pictureResponseCall = service.getPictureList(KEYWORD, CLIENT_ID);
pictureResponseCall.enqueue(new Callback<PictureResponse>() {
#Override
public void onResponse(Call<PictureResponse> call, Response<PictureResponse> response) {
if (response.isSuccessful()){
PictureResponse pictureResponse = response.body();
ArrayList<UnsplashPic> pictureList = pictureResponse.getResults();
recyclerViewAdapter.addPictures(pictureList);
}else{
Log.e (TAG, " onResponse " + response.errorBody());
}
}
#Override
public void onFailure(Call<PictureResponse> call, Throwable t) {
Log.e (TAG, " onFailure " + t.getMessage());
}
});
}
}
My adapter class:
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {
private ArrayList<UnsplashPic> pictureList;
public RecyclerViewAdapter (){
pictureList = new ArrayList<>();
}

#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {

}
#Override

viewHolder.artistName.setText(pic.user.getUsername());
viewHolder.unsplash.setText("Unsplash");
}
#Override

Here:
public void addPictures(ArrayList<UnsplashPic> pictureList) {
pictureList.addAll(pictureList);
notifyDataSetChanged();
}
you are actually adding the content of the pictureList you send as parameter of the function to that same list, your list from adapter is not updated.
You should do like this instead:
public void addPictures(ArrayList<UnsplashPic> pictureList) {
this.pictureList.addAll(pictureList);
notifyDataSetChanged();
}
I tried below code to implement an expend and collapse content using recyclerview(listview) a link
final boolean isExpanded = position==mExpandedPosition;
holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);
holder.itemView.setActivated(isExpanded);
if (isExpanded)
previousExpandedPosition = position;
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mExpandedPosition = isExpanded ? -1:position;
notifyItemChanged(previousExpandedPosition);
notifyItemChanged(position);
}
});
In my case when i click the particular position in recyclerview its expanding but it goes above the recyclerview.I cant see the full expanded content.i can see only partial content.In this case i need to scroll the recyclerview to view the full content.But i am searching for a solution to view the content without scroll the recyclerview. If i click another position in recyclerview that should be placed over an recyclerview.
Hear is My Code

Try to use NestedScrollView instead of ScrollView and set below to your activity :-
recyclerView.setNestedScrollingEnabled(false);
For more information you can refer below stackoverflow links:-

Hi I ma trying to build an app that has a list of events retrieved from a firebase database but when I run it it displays just the first event stored.
there is the code I used to generate the list:
private RecyclerView recyclerView;
private FirebaseRecyclerAdapter<Event,EventViewHolder> firebaseRecyclerAdapter;
#Override

{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_calendario);
recyclerView = (RecyclerView) findViewById(R.id.eventiList);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
Query query = FirebaseDatabase.getInstance().getReference("Eventi");
FirebaseRecyclerOptions<Event> options =
new FirebaseRecyclerOptions.Builder<Event>().setQuery(query, Event.class).build();
firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Event, EventViewHolder>(options) {
#NonNull

holder.setDay(model.getData().substring(0,2));
holder.setMonth(model.getMese());
holder.setName(model.getNome());
holder.setLuogo(model.getLuogo());
holder.setendStart(model.getOra_inizio()+ " - "+ model.getOra_fine());
holder.mview.setOnClickListener(new View.OnClickListener() {
#Override

});
}
};
recyclerView.setAdapter(firebaseRecyclerAdapter);

As you can see from the image that follows it displays just one event and I have 5 in the database
Display
The code worked fine for other lists that are in the app I don't understand why it is not working for this one hope I can get an answer here, thanks
Edit: this is the Database tree
Database Tree
Problem Solved, the layout_height parameter was set to match_parent in the event_layout LinearLayout and CardView. I set it to wrap_content on both and it worked.
I want to display the firebase data into the custom recyclerview. The data is added to the firebase from the arduino which i want to display in the app itself.
i am trying to run the following code but the app simply opens and doesnt display anything. Each time the app runs on the android, it opens and doesnt diaplay anything. The same code is working with my other 2-3 projects but doesnt seem to work in this case.
1.MainActivity.java
public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private DatabaseReference myref;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = findViewById(R.id.mango);
myref = FirebaseDatabase.getInstance().getReference().child("database").child("values");
FirebaseRecyclerAdapter<valueretriever, ProgramViewHolder> recyclerAdapter = new FirebaseRecyclerAdapter<valueretriever, ProgramViewHolder>(
valueretriever.class,
R.layout.individual_row,
ProgramViewHolder.class,
myref
) {
#Override
protected void populateViewHolder(ProgramViewHolder viewHolder, valueretriever model, int position) {
viewHolder.setMoisture(model.getMoisture());
viewHolder.setMotor_time(model.getMotortime());
viewHolder.setPower(model.getPower());
}
};
recyclerView.setAdapter(recyclerAdapter);
}
public static class ProgramViewHolder extends RecyclerView.ViewHolder {
View mView;
TextView txtmoisture;
TextView txtmotor_time;
TextView txtpower;
String moisturee, motortimee, powerr;
public ProgramViewHolder(View itemView) {
super(itemView);
mView = itemView;
txtmoisture = itemView.findViewById(R.id.textview1);
txtmotor_time = itemView.findViewById(R.id.textview2);
txtpower = itemView.findViewById(R.id.textview3);
}
public void setMoisture(String moisture) {
txtmoisture.setText(moisture);
moisturee = txtmoisture.getText().toString();
}
public void setMotor_time(String motor_time) {
txtmotor_time.setText(motor_time);
motortimee = txtmotor_time.getText().toString();
}
public void setPower(String power) {
txtpower.setText(power);
powerr = txtpower.getText().toString();

I have used a FirebaseRecyclerAdapter in my application for displaying a series of events. When i select an event form the recycler view it must expand the recycler view item and show me the details and other items of that event such as dates, description and others. I used a concept from Google I/O 2016 but could't land anywhere as my event is not showing only. I want only a specific set of items to be displayed when expanded.
EventView.java
public class EventView extends AppCompatActivity {
DatabaseReference databaseReference;
RecyclerView recyclerView;
int mExpandedPosition = -1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_event_view);
databaseReference = FirebaseDatabase.getInstance().getReference().child("ApprovedEvents");
recyclerView = (RecyclerView) findViewById(R.id.request_EventList);
//Avoid unnecessary layout passes by setting setHasFixedSize to true
recyclerView.setHasFixedSize(true);
//Select the type of layout manager you would use for your recyclerView
recyclerView.setLayoutManager(new LinearLayoutManager(this));
}
#Override
protected void onStart() {
super.onStart();
final String event_cat = getIntent().getStringExtra("Category");
FirebaseRecyclerAdapter<Event, RequestViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Event, RequestViewHolder>(
Event.class,
R.layout.events_list_row,
RequestViewHolder.class,
databaseReference.orderByChild("category").equalTo(event_cat)
) {
#Override
protected void populateViewHolder(RequestViewHolder viewHolder, Event model, int position) {
viewHolder.setTitle(model.getTitle());
viewHolder.setDesc(model.getDesc());
viewHolder.setCategory(model.getCategory());
viewHolder.setLocation(model.getLocation());
viewHolder.setPrice(model.getPrice());
viewHolder.setImageUrl(getApplicationContext(), model.getImageUrl());
viewHolder.imageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(EventView.this, "Image Selected", Toast.LENGTH_SHORT).show();
}
});
}
#Override
public void onBindViewHolder(RequestViewHolder viewHolder, final int position) {
super.onBindViewHolder(viewHolder, position);
final boolean isExpanded = position == mExpandedPosition;
viewHolder.mView.setVisibility(isExpanded?View.VISIBLE:View.GONE);
viewHolder.mView.setActivated(isExpanded);
viewHolder.mView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mExpandedPosition = isExpanded ? -1:position;
TransitionManager.beginDelayedTransition(recyclerView);
notifyDataSetChanged();
}
});
}
};
recyclerView.setAdapter(firebaseRecyclerAdapter);
}
public static class RequestViewHolder extends RecyclerView.ViewHolder {
View mView;
ImageView imageButton;
public RequestViewHolder(View itemView) {
super(itemView);
mView = itemView;
imageButton = (ImageView) mView.findViewById(R.id.request_image);
}
public void setTitle(String title) {
TextView a_title = (TextView) mView.findViewById(R.id.request_title);
a_title.setText(title);
}

a_desc.setText(desc);
}
public void setLocation(String location) {

a_desc.setText(location);
}
public void setCategory(String category) {

a_category.setText(category);
}
public void setPrice(String price) {
TextView a_price = (TextView) mView.findViewById(R.id.request_price);
a_price.setText(price);
}
public void setImageUrl(Context ctx, String imageUrl) {
ImageView a_image = (ImageView) mView.findViewById(R.id.request_image);
Picasso.with(ctx).load(imageUrl).into(a_image);
}
