Recyclerview On Click Listener Not Working

When i want to click recycler view then it should open another Activity Data is fetching but the problem is when i click on recycleview it displays nothing. I tried RecyclerView.O

Solution 1:

Using Interface you can solve your problem:

 publicinterfaceOnItemClickListener {
        publicvoidonItemClick(View view, int position,  List<AllRestaurant> AllRestaurant);
    }

Implement interface in your adapter class like this.

publicclassMyViewHolderextendsRecyclerView.ViewHolder  implementsView.OnClickListener {
        //public TextView long1, medium, small;
        TextView t1,t2,t3,t4,t5;
        ImageView logo;

        publicMyViewHolder(View view) {
            super(view);

            t1=(TextView)view.findViewById(R.id.t1);
            t2=(TextView)view.findViewById(R.id.t2);
            t3=(TextView)view.findViewById(R.id.t3);
            t4=(TextView)view.findViewById(R.id.t4);
            t5=(TextView)view.findViewById(R.id.t5);
            logo=(ImageView) view.findViewById(R.id.image);
            //   final AllRestaurant items = getItem(position);//long1.setText(items.getRestaurent_id());// final NotifyUsers notifyUsers=new NotifyUsers(context);// username.setText(items.getResponse_by());// little.setText(items.g);

        }

        @OverridepublicvoidonClick(View v) {
            if (mItemClickListener != null) {
                mItemClickListener.onItemClick(v, getPosition(), getData());
            }
        }
    }

Then call like that:

mRecyclerView.setAdapter(adapter);
 adapter.setOnItemClickListener(newOnItemClickListener() {

            @OverridepublicvoidonItemClick(View view, int position, List<UserDetails> userDetailsList) {
                Toast.makeText(getActivity(), "index --> " + position, Toast.LENGTH_SHORT).show();

            }

        });

Solution 2:

if you want on item click for recycle view First you need to create the following class :

publicclassRecyclerItemClickListenerimplementsRecyclerView.OnItemTouchListener {

protected OnItemClickListener listener;

private GestureDetector gestureDetector;

@Nullableprivate View childView;

privateint childViewPosition;

publicRecyclerItemClickListener(Context context, OnItemClickListener listener) {
    this.gestureDetector = newGestureDetector(context, newGestureListener());
    this.listener = listener;
}

@OverridepublicbooleanonInterceptTouchEvent(RecyclerView view, MotionEvent event) {
    childView = view.findChildViewUnder(event.getX(), event.getY());
    childViewPosition = view.getChildPosition(childView);

    return childView != null && gestureDetector.onTouchEvent(event);
}

@OverridepublicvoidonTouchEvent(RecyclerView view, MotionEvent event) {
    // Not needed.
}

@OverridepublicvoidonRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

}

/**
 * A click listener for items.
 */publicinterfaceOnItemClickListener {

    /**
     * Called when an item is clicked.
     *
     * @param childView View of the item that was clicked.
     * @param position  Position of the item that was clicked.
     */voidonItemClick(View childView, int position);

    /**
     * Called when an item is long pressed.
     *
     * @param childView View of the item that was long pressed.
     * @param position  Position of the item that was long pressed.
     */voidonItemLongPress(View childView, int position);

}

/**
 * A simple click listener whose methods can be overridden one by one.
 */publicstaticabstractclassSimpleOnItemClickListenerimplementsOnItemClickListener {

    /**
     * Called when an item is clicked. The default implementation is a no-op.
     *
     * @param childView View of the item that was clicked.
     * @param position  Position of the item that was clicked.
     */publicvoidonItemClick(View childView, int position) {
        // Do nothing.
    }

    /**
     * Called when an item is long pressed. The default implementation is a no-op.
     *
     * @param childView View of the item that was long pressed.
     * @param position  Position of the item that was long pressed.
     */publicvoidonItemLongPress(View childView, int position) {
        // Do nothing.
    }

}

protectedclassGestureListenerextendsGestureDetector.SimpleOnGestureListener {

    @OverridepublicbooleanonSingleTapUp(MotionEvent event) {
        if (childView != null) {
            listener.onItemClick(childView, childViewPosition);
        }

        returntrue;
    }

    @OverridepublicvoidonLongPress(MotionEvent event) {
        if (childView != null) {
            listener.onItemLongPress(childView, childViewPosition);
        }
    }

    @OverridepublicbooleanonDown(MotionEvent event) {
        // Best practice to always return true here.// http://developer.android.com/training/gestures/detector.html#detectreturntrue;
    }

}

}

The in you fragment class:

publicclassRestaurantFragmentextendsFragmentimplementsRecyclerItemClickListener.OnItemClickListener{
@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        Viewv= inflater.inflate(R.layout.layout, container, false);




list.addOnItemTouchListener(newRecyclerItemClickListener(getActivity().getApplicationContext(), this));





.....
 }

@OverridepublicvoidonItemClick(View childView, int position) {
    // add the code for the click here
}

@OverridepublicvoidonItemLongPress(View childView, finalint position) {
}
}

Let me know if you need any help

Solution 3:

Here is the solution i got with the help of recyclerview.addonItemTouchListener and creating Interface.

publicclassRestaurantFragmentextendsFragment {
        RecyclerView recyclerView;
        LinkedList<AllRestaurant> allRestaurants;
        RestaurantAdapter allRestaurantAdapter;
        MethodModel methodModel;

        @Nullable@Overridepublic View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
            View view= inflater.inflate(R.layout.restaurantlist, container, false);
            methodModel=newMethodModel(getActivity());
            allRestaurants=methodModel.getAllRestaurant();
            allRestaurantAdapter=newRestaurantAdapter(allRestaurants);
            recyclerView=(RecyclerView)view.findViewById(R.id.recycler_view);

            RecyclerView.LayoutManagermLayoutManager=newLinearLayoutManager(getActivity());
            recyclerView.setLayoutManager(mLayoutManager);
            recyclerView.setItemAnimator(newDefaultItemAnimator());
            recyclerView.addItemDecoration(newDividerItemDecoration(getActivity(), LinearLayoutManager.VERTICAL));

    // set the adapter
            recyclerView.setAdapter(allRestaurantAdapter);
            recyclerView.addOnItemTouchListener(newRecyclerTouchListener(getActivity(), recyclerView, newClickListener() {
                @OverridepublicvoidonClick(View view, int position) {

                }

                @OverridepublicvoidonLongClick(View view, int position) {

                }
            }));
            return view;
        }

        classRecyclerTouchListenerimplementsRecyclerView.OnItemTouchListener{
    publicRecyclerTouchListener(Context context, RecyclerView recyclerView, ClickListener clicklistener){

            }

            @OverridepublicbooleanonInterceptTouchEvent(RecyclerView rv, MotionEvent e) {

                Log.d("Performing Better", "onInterceptTouchEvent: "+e);
                startActivity(newIntent(getActivity(), Details.class));

                returnfalse;
            }

            @OverridepublicvoidonTouchEvent(RecyclerView rv, MotionEvent e) {
                Log.d("On Touch Event Better", "onTouchEvent: "+e);
            }

            @OverridepublicvoidonRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

            }
        }
        publicstaticinterfaceClickListener {

            publicvoidonClick(View view, int position);
            publicvoidonLongClick(View view, int position);
        }
    }
