title: Android - Get data from many webservice (JSON) on a fragment same time
body: <p>I am developing a fragment that allow get data from many webservice (JSON) same time. Let's imagine with this image:
  <a href="https://i.stack.imgur.com/rEX3s.png" rel="nofollow noreferrer"><strong>demo image</strong></a></p>
  
  <ul>
  <li>Request data ( this method will call a function that download json and send the response via callback listener </li>
  </ul>
  
  <blockquote>
  <pre><code>&gt; @Override
      public void onCreate(@Nullable Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          BaseDataReponsitory baseDataReponsitory = new BaseDataReponsitory();
          baseDataReponsitory.getDataFromURL(url1, this);
          baseDataReponsitory.getDataFromURL(url2, this);
      }
  </code></pre>
  </blockquote>
  
  <ul>
  <li>Receive data:</li>
  </ul>
  
  <blockquote>
  <pre><code> @Override
      public void loadListFromURLFinish(String json) {
          ListEntity listEntity = gson.fromJson(json, ListEntity.class);
          mList.addAll(listEntity.getEntityList());
          Log.d(TAG, "loadListFromURLFinish: " + mList.size());
      }
  </code></pre>
  </blockquote>
  
  <p>Data log is 4 and 9 . It is correct ( JSON 1 has 4 element, JSON 2 has 9 element). 
  My question is how I split data to set for view (see the above image)? </p>
