Setting different `onclick listener` to each `button` in `recyclerView`

Question

hi I'm making a cheats app which have cheat codes for a game (gtav), how can I set a different onclicklistener to each button in recyclerView. For example I have a button in recyclerView called copytoclip board and I want each button in the recyclerView to copy a different text. How can I do that?

@Override

    Cheats cheats = cheatList.get(position);
    holder.title.setText(cheats.getTitle());
    holder.cheat.setText(cheats.getCheat());
    holder.description.setText(cheats.getDescription());

    holder.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                // TO DO
                // if this happens to all the buttons..insert here a switch recognizing which button is pressed through getting an info of the button maybe

                }
            });

change into your adapter class

  public class CheatsAdapter extends` `RecyclerView.Adapter`<CheatsAdapter.MyViewHolder> `{`

    private List<Cheats> cheatList;
    public class MyViewHolder extends RecyclerView.ViewHolder{
        public TextView title, cheat, description;
        public Button btnClick;
        public MyViewHolder(View view){
            super(view);
            btnClick= (Button )view.findViewById(R.id.cpytocp);

            title = (TextView)view.findViewById(R.id.title);
            cheat = (TextView) view.findViewById(R.id.cheat);
            description = (TextView) view.findViewById(R.id.description);
        }
    }

    public CheatsAdapter(List<Cheats> cheatList){
        this.cheatList = cheatList;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.cheat_list, parent, false);

        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
        Cheats cheats = cheatList.get(position);
btnClick.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // do that you want to perform on click
            }
        });        holder.title.setText(cheats.getTitle());
        holder.cheat.setText(cheats.getCheat());
        holder.description.setText(cheats.getDescription());
    }

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

Add onclick event in the button xml android:onClick="doSomething"

<Button
  android:layout_height="wrap_content"
  android:layout_width="wrap_content"
  android:text="Copy"
  android:id="@+id/cpytocp"
  android:layout_gravity="top|right" 
  android:onClick="copyToClipboard" />

Then you need to create the referenced method in your activity / fragment:

public void copyToClipboard(View v) {
    ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); 
    ClipData clip = ClipData.newPlainText(label, text);
    clipboard.setPrimaryClip(clip);
}

---

NOTES:

• If you want to manage various buttons / elements you must add a switch(v.getId()) to know which element was clicked
• copyToClipboard code is taken as example from here
