title: How to put a button inside group item in an ExpandableListView?
body: <p>I'm developing an application for Android.</p>
  
  <p>How could I put a button in a group of a ExpandableListView?</p>
  
  <p>By clicking the button a dialog will be displayed instead of open or close the group. Click outside the button, the group should behave normally opening and closing.</p>
  
  <p>The image below shows where I would like to insert the button.</p>
