[Solved] No response from jsonArray request [closed]

by


1. Initialize your adapter and set it to RecyclerView from onCreate() method.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //Initializing Views
    recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
    recyclerView.setHasFixedSize(true);
    layoutManager = new LinearLayoutManager(this);
    recyclerView.setLayoutManager(layoutManager);

    listcollege = new ArrayList<>();
    adapter = new CardAdapter(this, listcollege);
    recyclerView.setAdapter(adapter);

    getData();
}

2. Instead of JsonArrayRequest, try using JsonObjectRequest: 

//Creating a json object request
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest (Config.DATA_URL,
        new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                //Dismissing progress dialog
                Toast.makeText(MainActivity.this, "sachin", Toast.LENGTH_SHORT).show();
                loading.dismiss();

                // College 
                JSONArray jsonArrayCollege = response.getJSONArray("College");

                // calling method to parse json array
                parseData(jsonArrayCollege);
            }
        },
        new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {

            }
        });

//Creating request queue
RequestQueue requestQueue = Volley.newRequestQueue(this);

//Adding request to the queue
requestQueue.add(jsonObjectRequest);

3. Update parseData() method as below:

public  void parseData(JSONArray array) {
    for (int i = 0; i < array.length(); i++) {
        College college = new College();
        JSONObject json = null;
        try {
            json = array.getJSONObject(i);
            college.setImageUrl(json.getString(Config.TAG_IMAGE_URL));
           String s = (json.getString(Config.TAG_NAME));
            Toast.makeText(this, s, Toast.LENGTH_SHORT).show();
            college.setName(s);

        } catch (JSONException e) {
            e.printStackTrace();
        }
        listcollege.add(college);
    }  
    adapter.notifyDataSetChanged();
}

Hope this will help~
