title: Set SimpleAdapter in fragment for ListView
body: <p>i have successfully implemnted a listview based on a Simpleadapter. Now i wanted to split my application into three tabs. But if i want to set the simpleadapter on my fragment the listview shows nothing and i get no error.</p>
  
  <pre><code>protected void onPostExecute(Void result) {
          super.onPostExecute(result);
          // Dismiss the progress dialog
          if (pDialog.isShowing())
              pDialog.dismiss();
          /**
           * Updating parsed JSON data into ListView
           * */
          adapter = new SimpleAdapter(
                  this.getContext(), contactList,
                  R.layout.list_item, new String[]{"listTitle", "tonart"}, new int[]{R.id.id,
                  R.id.tonart});
  
          lv.setAdapter(adapter);
  </code></pre>
  
  <p>i used the same code as in the working app.</p>
  
  <p>Thanks</p>
