How to pass data from Recyclerview to Fragment

If you are working with kotlin, the solution is much simpler. Original Answer here

pass the function val itemClick: (Int) -> Unit to your adapter.

class MyRecyclerViewAdapter(params , val itemClick: (Int) -> Unit): RecyclerView.Adapter<RecyclerView.ViewHolder>() {
internal inner class MyViewHolder(view: View) : RecyclerView.ViewHolder(view) {
    ...
    itemView.setOnClickListener( {itemClick(layoutPosition)} )
  } 
}  

In your fragment use the returned value position

val myAdapter = MyRecyclerViewAdapter(params) { position ->
    // do something
}

Either creating a listener interface in the adapter or using regular old getters, if I understand your question correctly.


thank you guys for the answer,I solved the problem using an interface with String values to connect the adapter with the fragment that contains the recyclerview and the other fragment here is what I did exactly : this is the interface

public interface FragmentCommunication {
    void respond(int position,String name,String job);
}

and this is the adapter

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.MyViewHolder> {
    private LayoutInflater inflater;
    private List<Information> mList;
    private FragmentCommunication mCommunicator;

    public RecyclerAdapter(Context context, List<Information> list,FragmentCommunication communication) {
        inflater = LayoutInflater.from(context);
        mList = list;
        mCommunicator=communication;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = inflater.inflate(R.layout.single_row, parent, false);
        MyViewHolder holder = new MyViewHolder(view,mCommunicator);
        return holder;
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, final int position) {

        final Information current = mList.get(position);
        holder.name.setText(current.name);
        holder.job.setText(current.job);

        FragmentB fragmentB=new FragmentB();
        Bundle bundle=new Bundle();
        bundle.putString("NAME",current.name);
        bundle.putString("JOB",current.job);
        fragmentB.setArguments(bundle);

    }

    @Override
    public int getItemCount() {
        return mList.size();
    }

    public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView name;
        TextView job;
        FragmentCommunication mComminication;

        public MyViewHolder(View itemView, FragmentCommunication Communicator) {
            super(itemView);
            name = (TextView) itemView.findViewById(R.id.tv_name);
            job = (TextView) itemView.findViewById(R.id.tv_gob);
            mComminication=Communicator;
            name.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
            mComminication.respond(getAdapterPosition(),mList.get(getAdapterPosition()).name,mList.get(getAdapterPosition()).job);
        }
    }
}

the fragment that contains the recyclerview

public class RecyclerViewFragment extends Fragment {
    RecyclerView mRecyclerView;
    RecyclerAdapter mRecyclerAdapter;
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view= inflater.inflate(R.layout.recycler_fragment,container,false);

        mRecyclerView= (RecyclerView) view.findViewById(R.id.recycler);
        mRecyclerAdapter=new RecyclerAdapter(getActivity(),getData(),communication);
        mRecyclerView.setAdapter(mRecyclerAdapter);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

        return view;
    }

    public static List<Information> getData() {
        List<Information>data=new ArrayList<>();
        String[] names={"ahmed","mohammed"};
        String[] jobs={"sacsd","csscs"};

        for (int i=0;i<names.length;i++){
            Information current=new Information();
            current.name=(names[i]);
            current.job=(jobs[i]);
            data.add(current);
        }
        return data;
    }

    FragmentCommunication communication=new FragmentCommunication() {
        @Override
        public void respond(int position,String name,String job) {
            FragmentB fragmentB=new FragmentB();
            Bundle bundle=new Bundle();
            bundle.putString("NAME",name);
            bundle.putString("JOB",job);
            fragmentB.setArguments(bundle);
            FragmentManager manager=getFragmentManager();
            FragmentTransaction transaction=manager.beginTransaction();
            transaction.replace(R.id.dumper,fragmentB).commit();
        }

    };

}

this is the fragmentB where I get the Strings from the Adapter

    public class FragmentB extends Fragment {
    TextView textview;
    TextView textview2;
    String name;
    String job;

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        name=getArguments().getString("NAME");
        job=getArguments().getString("JOB");

    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view= inflater.inflate(R.layout.fragment_b,container,false);

        textview= (TextView) view.findViewById(R.id.getName);
        textview2= (TextView) view.findViewById(R.id.getJob);
        textview.setText(name);
        textview2.setText(job);


        return view;

    }


}
