can you give me some reference about parent-child recycleview? i have successfully made parent-Recycleview but i'm stuck to pass child-Recycleview when im clicked item from parent
NB: i'm use dummy data
This is example of recyclerview I want to create:
and this is my code

Thanks for helping
you need to populate the RecycleChildAdapter.java in the onBindViewHolder of RecycleParentAdapter.java
like:
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private CircleImageView storeImage;
private TextView storeName;
public RecyclerView recycler_view_child;
ViewHolder(View itemView) {
super(itemView);
storeImage = itemView.findViewById(R.id.ivListStoreImage);
storeName = itemView.findViewById(R.id.tvListStoreName);
recycler_view_child = view.findViewById(R.id.recyclerchild);
itemView.setOnClickListener(this);
}
and:
public class RecycleParentMenuAdapter extends RecyclerView.Adapter<RecycleParentMenuAdapter.ViewHolder>{
private ArrayList<Store> mData;
private LayoutInflater mInflater;
private ItemClickListener mClickListener;
public RecycleChildAdapter adapter;
finally:
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, int position) {
holder.storeName.setText(mData.get(position).getName());
// holder.storeImage.setImageURI(mData.get(position).getImage());
LinearLayoutManager manager=new LinearLayoutManager(context);
manager.setOrientation(LinearLayoutManager.HORIZONTAL);
holder.recycler_view_child.setLayoutManager(manager);
adapter = new ChildAdapter(yourdatalist, context);
holder.recycler_view_child.setAdapter(adapter);
}

I need some help with two of my recycler views(one named "recentRecycler", and the other "topPlacesRecycler").My question is, how do I make to be redirected on a specific Activity when I click a specific item from the recycler. For example:
1- when I click the first item from the "recentRecycler" to be redirected to "Parlament.class"
2- when I click the first item from the "topPlacesRecycler" to be redirected to "Ramada.class"

I'm pretty new with Android Studio so every feedback would be gladly accepted.
Thanks in advance!
The best solution that does not overload the adapter would be to use interface.
Declare an interface in your adapter like this...
public class RecentsAdapter extends RecyclerView.Adapter<RecentsAdapter.RecentsViewHolder> {
Context context;
List<RecentsData> recentsDataList;
private RecentsAdapter.OnRecentItemclickListener listener;
public void setOnRecentItemclickListener(RecentsAdapter.OnRecentItemclickListener listener){
this.listener = listener;
}
public RecentsAdapter(Context context, List<RecentsData> recentsDataList) {
this.context = context;
this.recentsDataList = recentsDataList;
}
#NonNull
#Override
public RecentsViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.recents_row_item, parent, false);
return new RecentsViewHolder(view, listener);
}
#Override
public void onBindViewHolder(#NonNull RecentsViewHolder holder, int position) {
holder.countryName.setText(recentsDataList.get(position).getCountryName());
holder.placeName.setText(recentsDataList.get(position).getPlaceName());
holder.price.setText(recentsDataList.get(position).getPrice());
holder.placeImage.setImageResource(recentsDataList.get(position).getImageUrl());
}
#Override
public int getItemCount() {
return recentsDataList.size();
}
public static final class RecentsViewHolder extends RecyclerView.ViewHolder{
ImageView placeImage;
TextView placeName, countryName, price;
public RecentsViewHolder(#NonNull View itemView, RecentsAdapter.OnRecentItemclickListener listener) {
super(itemView);
placeImage = itemView.findViewById(R.id.place_image);
placeName = itemView.findViewById(R.id.place_name);
countryName = itemView.findViewById(R.id.country_name);
price = itemView.findViewById(R.id.price);
itemView.setOnclickListener( -> {
if(listner == null)return;
int pos = getAdapterposition()
if(pos == RecyclerView.NO_POSITION)return;
listner.onRecentItemclickListener(pos);
});
}
}
public interface OnRecentItemclickListener {
void onRecentItemClickListener(int position);
}
}
Add then in you activity
private void setRecentRecycler(List<RecentsData> recentsDataList){
recentRecycler = findViewById(R.id.recent_recycler);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this, RecyclerView.HORIZONTAL, false);
recentRecycler.setLayoutManager(layoutManager);
recentsAdapter = new RecentsAdapter(this, recentsDataList);
recentRecycler.setAdapter(recentsAdapter);
recentsAdapter.setOnRecentItemclickListener(this::onOpenParlamentClass)
}
private void onOpenParlamentClass(int position){
//perform your intent here. you can also get the clicked item using the position of the data list and pass it to the receiving activity
}
Happy coding. If you are new to android you can also consider Kotlin.
public static final class RecentsViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
ImageView placeImage;
TextView placeName, countryName, price;
public RecentsViewHolder(#NonNull View itemView) {
super(itemView);
placeImage = itemView.findViewById(R.id.place_image);
placeName = itemView.findViewById(R.id.place_name);
countryName = itemView.findViewById(R.id.country_name);
price = itemView.findViewById(R.id.price);
itemView.setOnClickListener(this);
//you can do same code for another recyclerview.
}
#Override
public void onClick(View view) {
Intent intent = new Intent(context, Parlament.class);
view.getContext().startActivity(intent);
}
}
I'm referring this tutorial ==> https://uniqueandrocode.com/add-to-favourites-and-display-favourites-in-recyclerview/ in my project I have bottom navigation...I am trying to add favourites in the first tab and displaying favourites in the second tab in the bottom navigation bar. I'm using Room library.
When activity loads favourites are all blank at first, but when I first row as favourite and go-to favourite tab it displays properly but when I came back to the first tab it fills all the favourites icon automatically (which I have not done I had only done the first row)
Really need help. Thanks in advance.

Steps to debug:
Add 2-3 items as Favs.
Restart the Application.
Check if it shows those items as fav after restarting application .
also add logs to those if conditions where you are changing the drawables.
After looking at your JSON it looks like id is what creating problems. Id is null for all your json items so when fav. one it shows fav. to all.
Solution : Use another field to check if the data is added to fav.list
Delete will not work either
Try
#Query("DELETE FROM favoritelist WHERE title = :title")
void deleteByUserId(String title);
To delete item
