title: Clear custom ListAdapter
body: <p>I have a problem with my adapter. All works fine but i have a problem with clearing my list.</p>
  
  <p>I clear it like this:</p>
  
  <pre><code>public void onResetClicked(View v) {
      Log.d(TAG, "reset button clicked");
      m_stopwatchService.reset();
  
          alist.clear();
      }
  </code></pre>
  
  <p>It doesn't work.</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>It works but I can not re-create the list.</p>
  
  <pre><code>public void onResetClicked(View v) {
      Log.d(TAG, "reset button clicked");
      m_stopwatchService.reset();
  
          alist.clear();
          listView.setAdapter(null);
      }
  </code></pre>
  
  <p>It is a stopwatch. My adapter creates lap. When I press the "Reset Button" wants to clean the list of my laps.</p>
  
  <p><strong>EDIT2</strong></p>
  
  <p>I solved my problem.</p>
  
  <p>I called it like this :</p>
  
  <pre><code>listView.setAdapter(null);
          listView.setAdapter(adapter);
  </code></pre>
