    <p>I have a listActivity that shows CAB on long click. If more than 1 item is selected I would like to hide one of my menu items. </p> <p>I keep track of the # of items selected in <code>onItemCheckedStateChanged()</code>. However I don't have access to the menu to remove the item from this function. See comments in code below to get an idea of what I was trying. I feel like I am missing some simple core understanding... code below is called from my <code>onCreate()</code> function.</p> <pre><code>private void setupActionBarContext() { ListView listView = getListView(); listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL); listView.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener() { private int selCount = 0; ArrayList&lt;Long&gt; idList = new ArrayList&lt;Long&gt;(); @Override public void onItemCheckedStateChanged(ActionMode mode, int position, long id, boolean checked) { if (checked) { selCount++; idList.add(id); } else { selCount--; idList.remove(id); } mode.setTitle(selCount + " selected"); // I WOULD LIKE TO HIDE ITEM ON MENU IF 'selCount' IS &gt; 1 // For example something like this... // if (selCount &gt; 1) { // MenuItem item = menu.findItem(R.id.edit_item); // item.setVisible(false); // } else { // MenuItem item = menu.findItem(R.id.edit_item); // item.setVisible(false); // } } @Override public boolean onActionItemClicked(ActionMode mode, MenuItem item) { switch (item.getItemId()) { case R.id.delete_item: for(Long i: idList){ mDbHelper.deleteItem(i); } mode.finish(); return true; case R.id.edit_item: Toast.makeText(getBaseContext(), "Edit Item", Toast.LENGTH_SHORT).show(); mode.finish(); // Action picked, so close the CAB return true; default: return false; } } @Override public boolean onCreateActionMode(ActionMode mode, Menu menu) { // Inflate the menu for the CAB MenuInflater inflater = mode.getMenuInflater(); inflater.inflate(R.menu.context_menu, menu); return true; } @Override public void onDestroyActionMode(ActionMode mode) { selCount = 0; idList.clear(); } @Override public boolean onPrepareActionMode(ActionMode mode, Menu menu) { return false; } }); </code></pre> <p>And my menu item...</p> <pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;item android:id="@+id/edit_item" android:title="@string/edit_item" android:showAsAction="ifRoom" android:orderInCategory="1"/&gt; &lt;item android:id="@+id/delete_item" android:title="@string/delete_item" android:icon="@drawable/ic_action_delete" android:showAsAction="ifRoom" android:orderInCategory="2"/&gt; &lt;/menu&gt; </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
