RecyclerView无法单击，不起作用

Question

The main problem is that recyclerview is not clickable. But I might use the wrong way to delete "!" when intent to the next pages, which is map. If I do this way the map only shows one user marker, but it is supposed to show two markers.

In ListOnline.java

private void updateList() {
    adapter = new FirebaseRecyclerAdapter<User, ListOnlineViewHolder>(
        User.class,
        R.layout.user_layout,
        ListOnlineViewHolder.class,
        counterRef
    ){

        @Override
        protected void populateViewHolder(ListOnlineViewHolder viewHolder, final User model, int position) {
            viewHolder.txtEmail.setText(model.getEmail());

            // item click recycler view
            viewHolder.itemClickListenener = new ItemClickListenener() {
                @Override
                public void onClick(View view, int position) {
                    //if model is current user , not set click event

                    if(!model.getEmail().equals(FirebaseAuth.getInstance().getCurrentUser().getEmail()))
                    {
                        Intent map = new Intent(ListOnline.this, MapTracking.class);
                        map.putExtra("email",FirebaseAuth.getInstance().getCurrentUser().getEmail());
                        map.putExtra("lat",mLastLocation.getLatitude());
                        map.putExtra("lng",mLastLocation.getLongitude());
                        startActivity(map);
                    }
                }
            };
        }
    };
    adapter.notifyDataSetChanged();
    listOnline.setAdapter(adapter);
}

After I change like this , i can be clickable but cant receive the friend marker.

if(model.getEmail().equals(FirebaseAuth.getInstance().getCurrentUser().getEmail()))

means, i delete the '!' it can be intent to google map.

In ListOnlineViewHolder.java

public class ListOnlineViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
    public TextView txtEmail;
    ItemClickListenener itemClickListenener;

    public ListOnlineViewHolder(View itemView) {
        super(itemView);
        txtEmail = (TextView)itemView.findViewById(R.id.txt_email);
        itemView.setOnClickListener(this);
    }

    public void setItemClickListenener(ItemClickListenener itemClickListenener){
        this.itemClickListenener = itemClickListenener;
    }

    @Override
    public void onClick(View view) {
        itemClickListenener.onClick(view,getAdapterPosition());
    }}

In ItemClickListenener Interface

public interface ItemClickListenener {
    void onClick(View view, int position);
}

In MapTracking

 private void loadLocationForThisUser(String email) {
        Query user_location = locations.orderByChild("email").equalTo(email);

        user_location.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
                for(DataSnapshot postSnapShot:dataSnapshot.getChildren())
                {
                    Tracking tracking = postSnapShot.getValue(Tracking.class);

                    //add marker for friend location
                    LatLng friendLocation = new LatLng(Double.parseDouble(tracking.getLat()),
                            Double.parseDouble(tracking.getLng()));

                    //create location from user coordinates
                    Location currentUser = new Location("");
                    currentUser.setLatitude(lat);
                    currentUser.setLongitude(lng);

                    //create location from friend coordinates
                    Location friend = new Location("");
                    friend.setLatitude(Double.parseDouble(tracking.getLat()));
                    friend.setLongitude(Double.parseDouble(tracking.getLng()));

                    //create function calculate distance between location
//                    distance(currentUser,friend);

                    //add friend marker on map
                    mMap.addMarker(new MarkerOptions()
                    .position(friendLocation)
                    .title(tracking.getEmail())
                            .snippet("Distance "+new DecimalFormat("#.#").format( distance(currentUser,friend)))
                    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE)));
                    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(lat,lng),12.0f));
                }
                //create marker for current user
                LatLng current = new LatLng(lat,lng);
                mMap.addMarker(new MarkerOptions().position(current).title(FirebaseAuth.getInstance().getCurrentUser().getEmail()));
            }

            @Override
            public void onCancelled(DatabaseError databaseError) {

            }
        });
    }
