}
Here is my app
I would do something like this:
Create an Interface for your activity to implement:
public interface CallbackIF {
double tally(double amount, int quantity)
}
public class PembelianActivity extends AppCompatActivity implements CallbackIF {
#Override
public double tally(double amount, int quantity) {
return amount * quantity;
}
}
Then when you initialize your recyclerview adapter pass in the interface like so:
adData = new AdapterDataPembelian(PembelianActivity.this, listDataPembelian, PembelianActivity.this);
And change your constructor for the data adapter to be
private CallbackIF callback;
public AdapterDataPembelian(Context ctx, List<DataModel> listDataPembelian, CallbackIF callback) {
this.ctx = ctx;
this.listDataPembelian = listDataPembelian;
this.callback = callback;
}
Then in your onClicklistener for your list / wherever you want to trigger a tally just call
double value = callback.tally(amount, quantity);
If you have any questions please ask

Here is the structure of my database
Follow these steps to show images in RecyclerView
Remove ImageView from ProductModel
Add String imageUrl to ProductModel and set its value with the image URL from Firestore (I see from the screenshot that it is named "Image").
In onBindViewHolder from the ProductAdapter, use the position provided to retrieve the appropriate ProductModel from productModelArrayList and pass its imageUrl value to ProductViewHolder.
In ProductViewHolder, use the imageUrl to load the image into the ImageView. (Glide and Picasso are two commonly used library to load images)
PS: Never add UI elements in your model. It will cause lifecycle issues in the future.
Let me know if you have any questions.
I want to filter what gonna appear in the recyclerview
is it possible ?
There is a CalendarView and i want that when someone clicks in a day from the calendarview, it shows itemviews just from that date, for example when someone click in day 15 of the month may, it shows just the tasks that is for that day
I do not know if is it possible.
If someone can help me, it would be great.

I'm getting an error E/RecyclerView: No adapter attached; skipping layout while using FirestoreRecylerAdapter INSIDE a FRAGMENT. After reading all answers to similar questions ,I'm not able to reach to a solution because most of them are for recylerAdapter inside activiy, i.e. they have an onCreate method where they can set up their adapter first. In fragments as you know,there is no view in onCreate method so I can't find my recyclerView there.Some answers are suggesting to setup an empty adapter and then notify for data change.
I'm not able to able to setup an empty adapter in onCreateView. Here's my code:
My adapter:
package com.example.XX;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import com.firebase.ui.firestore.FirestoreRecyclerAdapter;
import com.firebase.ui.firestore.FirestoreRecyclerOptions;
public class ProfileRecyclerAdapter extends FirestoreRecyclerAdapter<Profile,ProfileRecyclerAdapter.ProfileViewHolder> {
public ProfileRecyclerAdapter(#NonNull FirestoreRecyclerOptions<Profile> options) {
super(options);
}
#Override
protected void onBindViewHolder(#NonNull ProfileViewHolder holder, int position, #NonNull Profile profile) {
holder.Name_textView.setText(profile.getName());
holder.Sector_textView.setText(profile.getSector());
holder.Pincode_textView.setText(profile.getPincode());
}
#NonNull
#Override
public ProfileViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
LayoutInflater layoutInflater=LayoutInflater.from(parent.getContext());
View view=layoutInflater.inflate(R.layout.profile_row_item,parent,false);
return new ProfileViewHolder(view);
}
class ProfileViewHolder extends RecyclerView.ViewHolder{
TextView Name_textView;
TextView Sector_textView;
TextView Pincode_textView;
public ProfileViewHolder(#NonNull View itemView) {
super(itemView);
Name_textView=itemView.findViewById(R.id.Name_textView);
Sector_textView=itemView.findViewById(R.id.Sector_textView);
Pincode_textView=itemView.findViewById(R.id.Pincode_textView);
}
}
}

}
});
}
}
Even if I comment out my button and onclicklistener and then run the app,I should be technically running an empty adapter. Still I'm getting the same error.
Please suggest what i should do,keeping in mind I CANNOT use onCreate
Edit Here is my edited code. Now I'm getting null Pointer exception and my app is crashing:

When you first create your Adapter in onCreateView(), you are not initializing that adapter, instead, you are setting the adapter right from the property:
ProfileRecyclerAdapter profileRecyclerAdapter;
recyclerView.setAdapter(profileRecyclerAdapter);
You need to initialize your adapter to set that adapter to your RecyclerView.
Second, you should not have that asynchronous call inside your onCreateView(), instead, use onViewCreated() to handle your asynchronous calls after your view is created.
Then, you are also making your adapter instance in your onViewCreated() with:
FirestoreRecyclerOptions<Profile> options = new FirestoreRecyclerOptions.Builder<Profile>()
.setQuery(query,Profile.class)
.build();
profileRecyclerAdapter = new ProfileRecyclerAdapter(options);
recyclerView.setAdapter(profileRecyclerAdapter);
profileRecyclerAdapter.startListening();
And you should do:
profileRecyclerAdapter.startListening();
In your onStart() and profileRecyclerAdapter.stopListening(); at your onStop()
Instead of using adapter.startListening and
adapter.stopListening use .setLifecycleOwner(this)
Check out this working code:
FirestoreRecyclerOptions<Profile> options = new FirestoreRecyclerOptions.Builder<Profile>()
.setQuery(query,Profile.class)
.setLifecycleOwner(this)
.build();
profileRecyclerAdapter = new ProfileRecyclerAdapter(options);
recyclerView.setAdapter(profileRecyclerAdapter)

Note that getRef does not accept position,
returns an error, which could be done in the code, I already searched here in the Forum but I did not find a solution, thank you ,Note that getRef does not accept position,
