But i want to know how to implement for on clicking the product i want to get the name in list (ImageTitleNameView is represnted in my code). The below shows my code.

FriendsFragment.java

public class FriendsFragment extends android.support.v4.app.Fragment {



List<GetDataAdapter> GetDataAdapter1;

RecyclerView recyclerView;

RecyclerView.LayoutManager recyclerViewlayoutManager;

RecyclerView.Adapter recyclerViewadapter;

String GET_JSON_DATA_HTTP_URL = "http://192.168.xx.x/1.php";
String JSON_IMAGE_TITLE_NAME = "image_title";
String JSON_IMAGE_URL = "image_url";

JsonArrayRequest jsonArrayRequest ;

RequestQueue requestQueue ;

public FriendsFragment() {
    // Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_friends, container, false);


    GetDataAdapter1 = new ArrayList<>();
    recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerview1);
    recyclerView.setHasFixedSize(true);
    recyclerViewlayoutManager = new LinearLayoutManager(getContext());
    recyclerView.setLayoutManager(recyclerViewlayoutManager);






    JSON_DATA_WEB_CALL();



    // Inflate the layout for this fragment
    return rootView;
}

public void JSON_DATA_WEB_CALL(){

    jsonArrayRequest = new JsonArrayRequest(GET_JSON_DATA_HTTP_URL,

            new Response.Listener<JSONArray>() {
                @Override
                public void onResponse(JSONArray response) {

                    Log.d("LOGTAG", "Response :"+response);

                    JSON_PARSE_DATA_AFTER_WEBCALL(response);
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {

                }
            });

    requestQueue = Volley.newRequestQueue(getContext());

    requestQueue.add(jsonArrayRequest);
}

    for(int i = 0; i<array.length(); i++) {

        GetDataAdapter GetDataAdapter2 = new GetDataAdapter();

        JSONObject json = null;
        try {

            json = array.getJSONObject(i);

            GetDataAdapter2.setImageTitleNamee(json.getString(JSON_IMAGE_TITLE_NAME));

            GetDataAdapter2.setImageServerUrl(json.getString(JSON_IMAGE_URL));

        } catch (JSONException e) {

            e.printStackTrace();
        }
        GetDataAdapter1.add(GetDataAdapter2);
    }

Answer 1

i want to know how to implement for on clicking the product i want to get the name in list

Because click listener is set to recyclerview layout and other Views are child View of recyclerview View. parameter of onClick method is instance of The view that was clicked.

Use v to access clicked row TextView data:

@Override
public void onClick(View v) {
     TextView textView = (TextView) v.findViewById(R.id.textView_item) ;
     Log.d("LOGTAG", "clicked : name "+textView.getText().toString() );
}

Answer 2

class ViewHolder extends RecyclerView.ViewHolder{

    public TextView imageTitleNameView;
    public NetworkImageView networkImageView ;

    public ViewHolder(View itemView) {

        super(itemView);

        imageTitleNameView = (TextView) itemView.findViewById(R.id.textView_item) ;

        networkImageView = (NetworkImageView) itemView.findViewById(R.id.VollyNetworkImageView1) ;

        networkImageView.setOnClickListener(..);
        imageTitleNameView.setOnClickListener(..);

    }
}
