How to delay startactivity() in android. So that volleys data can be used

I have a code in my android project which retrieves data using volley. I have an onclick item. What I want is, when I click the item:

1) The volley should get the data from API and after that 2) the startactivity() line executes.

But what is happening is that the startactivity() executes before volley completes.

My question is: what can be done to delay startactivity() so that volley gets the data first?

Here is my code:

public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
       final String str = (String) adapterView.getItemAtPosition(position);

       String url1 = "https://maps.googleapis.com/maps/api/place/details/json?placeid="+placeids.get(position)+"&key="+browserKey;

     JsonObjectRequest jsonObjReq2 = new JsonObjectRequest(url1, null, new Response.Listener<JSONObject>(){

            @Override
            public void onResponse(JSONObject response) {

                try {
                            String latitude = response.getJSONObject("result").getJSONObject("geometry").getJSONObject("location").getString("lat");
                            String longitude = response.getJSONObject("result").getJSONObject("geometry").getJSONObject("location").getString("lng");
                            editor2.putString("udupitown_endingpointlat_1", latitude);
                            editor2.putString("udupitown_endingpointlon_1", longitude);
                            editor2.putString("udupitown_endingpointplacename_1", str);

                            editor2.commit();

                    }
                catch (Exception e) {
                }
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
            }
        });
        MyApplication.getInstance().addToReqQueue(jsonObjReq2, "jreq2");*/


        Intent m = new Intent(view.getContext(), VolleyMapviewerinside.class );
        startActivity(m);
    }

volley to get the data from api and after that startactivity() line executes.

Then instead of calling startActivity just before adding request to addToReqQueue, start Activity inside onResponse method Response.Listener :

   @Override
      public void onResponse(JSONObject response) {

        // 1. save data in SharedPreferences
        // call startActivity for starting VolleyMapviewerinside Activity
      }
