title: how to disable ExpandableListView Accessibility announcement (Talkback)
body: <p>I have an issue with <code>ExpandableListView</code> overlay another view.<br>
  I tried to disable the <code>ExpandableListView</code> by:</p>
  
  <pre><code>public void isAccisability(boolean isActive)
  {
      expandableListCategories.setEnabled(false);
  
     expandableListCategories.setImportantForAccessibility
     (View.IMPORTANT_FOR_ACCESSIBILITY_NO);
      expandableListCategories.setFocusable(false);   
  }
  </code></pre>
  
  <p>I was able to disable the on click but the contentdescription of the list is still working and the focusing as well.</p>
