title: Android ActionMode replace Action Items dynamically
body: <p>I have implemented an ActionMode via ActionBarSherlock (thanks Jake Wharton for ABS!).</p>
  
  <p>Anyways, i am calling the
  <code>mActionMode.invalidate();</code> each time i click on a ListView item, which also increments/decrements a checkedCounter.</p>
  
  <p>Then inside the public boolean <code>onPrepareActionMode(ActionMode mode, android.view.Menu menu)</code> , I have to set the ActionMode contents according to the value of the checkedCounter.</p>
  
  <p>Code for the onPrepareActionMode is below : </p>
  
  <blockquote>
  <pre><code>    public boolean onPrepareActionMode(ActionMode mode,
                  android.view.Menu menu) {
              Log.d("ASDASD", "INSIDE ONPREPARE!");
              if (mActionMode == null) {
                  MenuInflater inflater = mode.getMenuInflater();
                  inflater.inflate(R.menu.contextualmultiple, menu);
                  return false;
              }
              if (checkedCount == 0) {
                  mActionMode.finish();
              } else if (checkedCount == 1 &amp;&amp; mActionMode != null) {
                  mActionMode.setTitle(checkedCount + " Message Selected");
                  MenuInflater inflater = mode.getMenuInflater();
                  inflater.inflate(R.menu.contextualmultiple, menu);
                  return true;
              } else if (checkedCount &gt; 1) {
                  mActionMode.setTitle(checkedCount + " Messages Selected");
                  MenuInflater inflater = mode.getMenuInflater();
                  inflater.inflate(R.menu.contextual, menu);
                  return true;
              }
              return true;
          }
  </code></pre>
  </blockquote>
  
  <p>NOW, the problem is that, when the checkCount is 1, it inflates the menu with say, 3 items in it.
  But, when the counter increments to 2, it inflates the other menu with 1 item, BUT adds on to the previously inflated menu, without nullifying the contents first.
  I.E.; now the ActionMode has 2 of previous + 1 of current in the Contextual ActionBar!</p>
  
  <p>How can i change my code to remove the previously existing menu items from the ActionMode when the <code>mActionMode.invalidate()</code> is called?</p>
  
  <p>P.S. : the onCreateActionMode() function is empty, as the onPrepareActionMode() does everything, including when the mActionMode is null and has a menu to be inflated for the first time.</p>
