Question

json数据未在布局中显示但显示活动何时完成

我有以下Jsonobject代码。我在我的应用程序中使用选项卡。最初它没有显示但是当我从另一个选项卡移动到我的json选项卡时，它显示了json对象的数据。

请帮我找错。

RequestQueue queue = Volley.newRequestQueue(getActivity());
    JsonObjectRequest myReq = new JsonObjectRequest(Request.Method.GET, "http://192.168.18.235:7777/cric/news.php",
              null,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                   try {
                       JSONArray posts = response.getJSONArray("data");
                       for (int i = 0; i < posts.length(); i++) {
                           JSONObject temp = posts.getJSONObject(i);

                           String author = temp.getString("author");
                           String content = temp.getString("content");
                           String date = temp.getString("date");
                           String imageUrl = temp.getString("imageUrl");
                           String time = temp.getString("time");
                           String title = temp.getString("title");
                           String url = temp.getString("url");
                           Log.i("jsontag",title);
                           newsFeed.add(new NewsItem(title, content,R.drawable.ic_menu_gallery,author,"2-2-2018","1-05pm","https://www.inshorts.com/en/news/tardigrades-selected-among-1st-species-to-leave-solar-system-1509779328721","http://www.deepspace.ucsb.edu/projects/ets?utm_source=inshorts&utm_medium=referral&utm_campaign=fullarticle "));
                       }
                   }
                   catch (Exception e){
                       Log.i("myTag",e.toString());
                   }
                }
            },new Response.ErrorListener(){
                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.i("errorTaf",error.toString());

        }
    }
    );
    queue.add(myReq);
