Question Detail

You have made some Java files in Android Project like :

import android.view.View;

/**
 * Created by Hemant Sharma on 2/2/2018.
 */
public interface ClickListener{
    public void onClick(View view,int position);
    public void onLongClick(View view, int position);
}

RecyclerTouchListener

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;

/**
 * Created by Hemant Sharma on 2/2/2018.
 */

public class RecyclerTouchListener implements RecyclerView.OnItemTouchListener{

    private ClickListener clicklistener;
    private GestureDetector gestureDetector;

    public RecyclerTouchListener(Context context, final RecyclerView recycleView, final ClickListener clicklistener){

        this.clicklistener=clicklistener;
        gestureDetector=new GestureDetector(context,new GestureDetector.SimpleOnGestureListener(){
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }

            @Override
            public void onLongPress(MotionEvent e) {
                View child=recycleView.findChildViewUnder(e.getX(),e.getY());
                if(child!=null && clicklistener!=null){
                    clicklistener.onLongClick(child,recycleView.getChildAdapterPosition(child));
                }
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
        View child=rv.findChildViewUnder(e.getX(),e.getY());
        if(child!=null && clicklistener!=null && gestureDetector.onTouchEvent(e)){
            clicklistener.onClick(child,rv.getChildAdapterPosition(child));
        }

        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView rv, MotionEvent e) {

    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
}

ADD THIS IS IN YOUR MAIN ACTIVITY

googleSearchList_recycler_view.addOnItemTouchListener(new RecyclerTouchListener(getActivity(), googleSearchList_recycler_view, new ClickListener() {
    @Override
    public void onClick(View view, final int position) {
        Intent intent = new Intent(getActivity(), DetailsActivity.class);
        intent.putExtra("ID", YOUR_ID_OF_ARRAY[position]);
        startActivity(intent);
    }
    @Override
    public void onLongClick(View view, int position) {
        Toast.makeText(getActivity(), "Long press on position :" +position,Toast.LENGTH_LONG).show();
    }
}));
