title: How do I loop through all dynamically created radiobuttons and how do I identify them?
body: <p>I've got an app that dynamically adds radiobuttons from json data. I don't really know how to find out which ones are selected though. There are the <code>radioButton.isSelected()</code> and the <code>radioGroup.getCheckedRadioButtonId()</code> but since it's dynamically created I cannot use names for all the objects.</p>
  
  <p>Is there a way to add them to a group upon creation and cycle through all of them later? I've got multiple radiogroups and not all of them but most are supposed to be checked. </p>
  
  <p>I'm using api lvl 7 (2.1) and I'm fairly new to this. Please explain in detail.</p>
