in SwipeRefreshLayout cannot be applied
to
(in.com.goalert.activity.MainActivity)

at

swipeRefreshLayout.setOnRefreshListener(this);


full code is below

// We first check for cached request

Answer

You can try to use below code for swipeRefreshLayout This code is work for me.

Here is SwipeRefreshLayout XML code snippiest.

  <android.support.v4.widget.SwipeRefreshLayout  xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/swipe_refresh_layout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:divider="@null"
        android:dividerHeight="0dp" />
</android.support.v4.widget.SwipeRefreshLayout>

Here is the java code snippiest look like as per your requirement or code

 final SwipeRefreshLayout swipeView = (SwipeRefreshLayout) findViewById(R.id.swipe_refresh_layout);

 swipeView.setEnabled(false);
 swipeView.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            swipeView.setRefreshing(true);
            (new Handler()).postDelayed(new Runnable() {
                @Override
                public void run() {
                    swipeView.setRefreshing(false);
                    try {
                        onRefresh();
                    } catch (Exception e) {
                       e.printStackTrace();
                    }
                }
            }, 3000);
        }
    });
  // user defined on-refresh method 
 private void onRefresh() {
    Log.i("onRefresh","onRefresh");
    fetchfeed();
}

private void fetchfeed() {
   Log.i("fetchfeed","fetchfeed");
   String URL_FEED = "http://www.goalert.in/feed/engineering.json";

   JsonObjectRequest jsonReq = new JsonObjectRequest(Request.Method.GET,
            URL_FEED, null, new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
            VolleyLog.d("Response",response.toString());
            if (response != null) {
                parseJsonFeed(response);
            }
        }
    }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            VolleyLog.d("", "Error: " + error.getMessage());
        }
    });
    AppController.getInstance().addToRequestQueue(jsonReq);
}

Remains you can use your code as per your requirement.

I suggest to try to use this solution. It will work
