Passing data from Recycler view onClick to Detail Activity with android databinding

Passing data from Recycler view onClick to Detail Activity with android databinding - android

I am having a list of items populating through recyclerview with android databinding technique and now I want to pass and populate the same data in detail Activity not getting the right thing to do such. So, kindly help to do this.
public class Fragment extends Fragment {
private FirebaseRecyclerAdapter adapter;
private Firebase mFirebaseRef = new Firebase("https://xyz.firebaseio.com/category/").child("list");
public Fragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
final View rootView = inflater.inflate(R.layout.recycler_view, container, false);
final RecyclerView recyclerView = (RecyclerView) rootView.findViewById(R.id.recycler_view);
adapter = new FirebaseRecyclerAdapter<List, ViewHolder>List.class, R.layout.fragment,
ViewHolder.class, mFirebaseRef) {
#Override
protected void populateViewHolder(ViewHolder viewHolder, List list, int i) {
FragmentBinding binding = viewHolder.getBinding();
binding.setList(list);
}
};
recyclerView.setAdapter(adapter);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
recyclerView.addItemDecoration(new DividerItemDecoration(getActivity(), null));
return rootView;
}
public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
public FragmentBinding binding;
public ViewHolder(View itemView) {
super(itemView);
binding = DataBindingUtil.bind(itemView);
itemView.setOnClickListener(this);
}
public FragmentBinding getBinding() {
return binding;
}
#Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), DetailedActivity.class);
**// need help here**
v.getContext().startActivity(intent);
}
}
#BindingAdapter("quantity")
public static void setQuantityText(TextView view, int quantity) {
view.setText(String.valueOf(quantity));
}
public static class Handlers {
public static void increment(View view, int max) {
FragmentBinding binding = DataBindingUtil.findBinding(view);
binding.setQuantity(Math.max(max, binding.getQuantity() + 1));
}
public static void decrement(View view, int min) {
FragmentBinding binding = DataBindingUtil.findBinding(view);
binding.setQuantity(Math.min(min, binding.getQuantity() - 1));
}
}
}

There are a few ways to do this. One is to make List Parcelable so that you can pass it as an Intent extra. You'll then be able to extract it and populate the Detail page.
public static final LIST = "ListContent";
#Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), DetailedActivity.class);
FragmentBinding binding = DataBindingUtil.findBinding(v);
intent.putExtra(LIST, binding.getList());
v.getContext().startActivity(intent);
}
Another is to pass only the ID for the List and read the information again in the detail binding. Add the ID to the List and then you'll be able to extract it when you start the activity:
public static final LIST_ID = "ListID";
#Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), DetailedActivity.class);
FragmentBinding binding = DataBindingUtil.findBinding(v);
intent.putExtra(LIST_ID, binding.getList().getId());
v.getContext().startActivity(intent);
}
Either way, you can pull the data from the intent in the onCreate of your details Activity:
public void onCreate(...) {
Intent intent = getIntent();
// Using ID:
int id = intent.getIntExtra(LIST_ID);
List list = loadListFromId(id);
// Using Parcelable:
List list = intent.getParcelableExtra(LIST);
//...
}

In the log.i that I have in the Post Execute of the async task I can see how the articles are formed (The Article class has a toString () function).
But I can't get the articles to be seen in the RecyclerView. What am I doing wrong?
Capture: Main screen with recyclerView empty...
Thanks!

Pass the instance of RecyclerView like -
new LoadArticlesTask().execute(MainScreen.mPrefs, MainScreen.hasRemember, view, rw_noticias, context);
Receive this on LoadArticlesTask as you are doing with View.
Don't re-initialize/use this code inside your class -
RecyclerView rw_noticias = view.findViewById(R.id.rw_noticias);

In your card_layout_article.xml, make height wrap_content for cardview:
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="wrap_content"
........
........
Also in the layout of your recycler view instead of ConstraintLayout try to use RelativeLayout as the parent:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/constraintLayout"
xmlns:tools="http://schemas.android.com/tools">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/rw_noticias"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>

Fragment not showing up after click button from adapter

I am trying to add a button in the end of my recycler view and make that add button appear as a fragment. Previously it worked. But I don't know why it doesn't work at the moment. I've changed it into Frame Layout according to google and some StackOverflow question but it is still not showing up. When I put a toast inside the onClick function, the toast showed up. It's weird. Is it wrong somewhere else?

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.

RecyclerView does not show list of objects

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<>();
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext())
.inflate(R.layout.item_view_holder, viewGroup, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull ViewHolder viewHolder, int i) {
UnsplashPic pic = pictureList.get(i);
viewHolder.artistName.setText(pic.user.getUsername());
viewHolder.unsplash.setText("Unsplash");
}
#Override
public int getItemCount() {
return pictureList.size();
}
public void addPictures(ArrayList<UnsplashPic> pictureList) {
pictureList.addAll(pictureList);
notifyDataSetChanged();
}
public class ViewHolder extends RecyclerView.ViewHolder {

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();
}

Recycler View with firebase just displaying the first instance

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
protected void onCreate(Bundle savedInstanceState)
{
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
#Override
public EventViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.event_layout, parent, false);
return new EventViewHolder(view);
}
#Override
protected void onBindViewHolder(#NonNull EventViewHolder holder, final int position, #NonNull Event model) {
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
public void onClick(View v) {
}
});
}
};
recyclerView.setAdapter(firebaseRecyclerAdapter);
}
public static class EventViewHolder extends RecyclerView.ViewHolder
{
View mview;
public EventViewHolder(View itemView)
{
super(itemView);
mview=itemView;
}
public void setDay(String day)
{
TextView mtext= (TextView)mview.findViewById(R.id.day);
mtext.setText(day);
}
public void setName(String name)
{
TextView maut=(TextView)mview.findViewById(R.id.Event_Name);
maut.setText(name);
}
public void setMonth(String month)
{
TextView maut=(TextView)mview.findViewById(R.id.month);
maut.setText(month);
}
public void setLuogo(String luogo)
{
TextView maut=(TextView)mview.findViewById(R.id.luogo);
maut.setText(luogo);
}
public void setendStart(String endStart)
{
TextView maut=(TextView)mview.findViewById(R.id.start_end);
maut.setText(endStart);
}
}
#Override
protected void onStart() {
super.onStart();
firebaseRecyclerAdapter.startListening();
}
#Override
protected void onStop() {
super.onStop();
//mAdapter.stopListening();
firebaseRecyclerAdapter.stopListening();
}
this is the code of the model class
public class Event {
private String Nome;
private String data;
private String descrizione;
private String luogo;
private String mese;
private String ora_fine;
private String ora_inizio;
private String type;
public Event()
{
}
public Event(String nome, String data, String descrizione, String luogo, String mese, String ora_fine, String ora_inizio, String type) {
Nome = nome;
this.data = data;
this.descrizione = descrizione;
this.luogo = luogo;
this.mese = mese;
this.ora_fine = ora_fine;
this.ora_inizio = ora_inizio;
this.type = type;
}
public String getNome() {
return Nome;
}
public String getData() {
return data;
}
public String getDescrizione() {
return descrizione;
}
public String getLuogo() {
return luogo;
}
public String getMese() {
return mese;
}
public String getOra_fine() {
return ora_fine;
}
public String getOra_inizio() {
return ora_inizio;
}
public String getType() {
return type;
}
}
this is the Calendar activity layout
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

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.
