public class ArrayAdapter extends RecyclerView.Adapter<ArrayAdapter.ViewHolder> {
private String[] divisionName;
ArrayAdapter(String[] phoneNumebr) {
    this.divisionName = phoneNumebr;
}

@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    Context context = parent.getContext();
    LayoutInflater inflater = LayoutInflater.from( context );
    View v = inflater.inflate( R.layout.element, parent, false );
    return new ViewHolder( v );
}

@Override
public void onBindViewHolder(@NonNull ViewHolder holder, final int position) {
    holder.cNumbers.setText(divisionName[position] );
    holder.itemView.setOnClickListener( new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Toast.makeText(this,divisionName[position],Toast.LENGTH_LONG).show();
        }
    } );

}

@Override
public int getItemCount() {
    return divisionName.length;
}

static class ViewHolder extends RecyclerView.ViewHolder{
    TextView cNumbers;

    ViewHolder(@NonNull View itemView) {

How to add OnClickListener in recyclerView according to the item position

Answer 1

How to add OnClickListener in recyclerView according to the item position

To add OnClickListener to RecyclerView items, you achieve that within your custom RecyclerView.ViewHolder class, by setting. onClickListener() to the View passed into the ViewHolder constructor

snippet from your code:

static class ViewHolder extends RecyclerView.ViewHolder{
    TextView cNumbers;

    ViewHolder(@NonNull View itemView) {
        super( itemView );
        this.cNumbers = itemView.findViewById( R.id.cNumbers );
        
        listItem.setOnClickListener(){
            @Override
            public void onClick(View v) {
                Toast.makeText(v.getContext(), "Click on position number: " + getAdapterPosition(), Toast.LENGTH_SHORT).show();
                Toast.makeText(v.getContext(), divisionName[getAdapterPosition()],Toast.LENGTH_LONG).show(); 
            }
        }
    }
}

Answer 2

Just Change Your Toast.

        Toast.makeText(holder.itemView.getContext(),"You clicked "+divisionName[position],Toast.LENGTH_SHORT).show();
