So I have a RecyclerView inside another RecyclerView. And in my onBind() method in recyclerView1 i am trying to set the data for recyclerView2 , the fact is that recyclerView1 has a FirebaseRecyclerAdapter and recyclerView2 has a custom RecyclerAdapter and the onCreate() method in recyclerView2's adapter is never called , so the data set is good but it doesn't create my recyclerView2 in the interface this recycler is empty.
I put a breakpoint on the OrderViewHolder onCreateViewHolder and it just skips this .
Here is the code from the recyclerView2's adapter onCreate and onBind methods :
adapterReceivedCommands = new FirebaseRecyclerAdapter<Comanda, ReceivedCommandsViewHolder>(optionsReceivedCommands) {
@NonNull
@Override
public ReceivedCommandsViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.item_command,parent,false);
layoutManagerOrder = new GridLayoutManager(parent.getContext(),3);
orderRecycler = (RecyclerView) itemView.findViewById(R.id.order_recycler);
orderRecycler.setLayoutManager(layoutManagerOrder);
fragmentItem = (LinearLayout)itemView.findViewById(R.id.item_layout);
return new ReceivedCommandsViewHolder(itemView);
}
@Override
protected void onBindViewHolder(@NonNull final ReceivedCommandsViewHolder receivedCommandsViewHolder, int i, @NonNull final Comanda comanda) {
receivedCommandsViewHolder.tableNmb.setText(comanda.getmasa());
orderModelArrayList = comanda.getcomanda();
mAdaptor = new RecyclerViewAdapter(this, orderModelArrayList);
receivedCommandsViewHolder.recyclerView.setAdapter(mAdaptor);
}
};
adapterReceivedCommands.startListening();
receivedCommandsRecycler.setAdapter(adapterReceivedCommands);
return view;
}
And here is the code from the custom recyclerView2's adapter :
public class RecyclerViewAdapter extends RecyclerView.Adapter<OrderViewHolder>{
private ArrayList<OrderModel> orderModels = new ArrayList<OrderModel>();
private FirebaseRecyclerAdapter<Comanda, ReceivedCommandsViewHolder> context;
public RecyclerViewAdapter(FirebaseRecyclerAdapter<Comanda, ReceivedCommandsViewHolder> context, ArrayList<OrderModel> orderModels) {
this.orderModels = orderModels;
this.context = context;
}
@NonNull
@Override
public OrderViewHolder onCreateViewHolder(@NonNull ViewGroup parent, final int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.item_order,parent,false);
OrderViewHolder holder = new OrderViewHolder(view);
return holder;
}
@Override
public void onBindViewHolder(@NonNull OrderViewHolder holder, int position) {
OrderModel curentModel = orderModels.get(position);
holder.cantitateTxt.setText(curentModel.getCantitate().toString());
holder.comandaTxt.setText(curentModel.getDenumireProdus());
}
@Override
public int getItemCount() {
return 0;
}
Your item count is zero:
@Override
public int getItemCount() {
return 0;
}
So RecyclerView doesn't see any items to inflate. You should fix it to return the size of your list:
@Override
public int getItemCount() {
return orderModels.size();
}
