I am working on a Android app since I am new I can't find a way to get the fragment class name ReadFragment into the Adapter onBindViewHolder method.Any hint how can I get the class name or index of the fragment since I am using 2 fragments and want to display diferent data in each.

Fragment:

public class ReadFragment extends Fragment {

View view;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,


    return view;


}

Adapter

@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {}
adapter android java

  1. Adapter Side
// ..
private Class fragmentCls;

public MyRecyclerViewAdapter(..., Class fragmentCls) {
    // ..
    this.fragmentCls = fragmentCls;
}
// ..
  1. Fragment Side
// ..
adapter = new MyRecyclerViewAdapter(.., MyFragment.class);
// ..
// recyclerView.setAdapter(adapter);
// ..

So then you can use the fragmentCls field to get to know which is the caller fragment..

You can check if the fragment in the container is instanceof any Fragment

Fragment fragment = context.getFragmentManager().findFragmentById(R.id.fragment_container);
if(fragment instanceof FirstFragmentClass){
   //do something
} else if(fragment instanceif SecondFragmentClass){
   //do something
}
