title: Scroll only in ExpandableListView's child group
body: <p>I am trying to disable scrolling in the groups when one group is expanded . And let the scrolling only in the expanded group's child zone.
  So far, the whole expandableListView 's scrolling is disabled.</p>
  
  <p>I created an ExpandableListView like this:</p>
  
  <pre><code>ExpandableListView mList;
  mList.setAdapter(new SimpleExpandableListAdapter(.... ));
  
  mList.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
      @Override
      public boolean onGroupClick(final ExpandableListView parent, final View v, final int groupPosition,
              final long id) {
  
          disableScroll(parent);
          return false;
      }
  });
  </code></pre>
  
  <p>The method <code>disableScroll</code> uses OnTouchListener ( see <a href="https://stackoverflow.com/questions/7611085/disable-scrolling-in-listview">Disable scrolling in listview</a> )</p>
  
  <pre><code>void disableScroll(final View view) {
      view.setOnTouchListener(new View.OnTouchListener() {
          @Override
          public boolean onTouch(final View v, final MotionEvent event) {
              return (event.getAction() == MotionEvent.ACTION_MOVE);
          }
      });
  }
  </code></pre>
  
  <p>Is it possible to enable the scrolling only in the ExpandableListView's childs when one group is expanded?</p>
