title: Select only one radiobutton in a recyclerview
body: <p>I have a recyclerview in which every item has 3 radiobuttons grouped in a radiogroup. Now a user can select only one radiobutton per item in recyclerview. But I want the user to select only one radiobutton throughout the recyclerview. How can this be achieved?</p>
  
  <p>This is how it looks currently. </p>

  <p>I would like to make it possible to check only 1 radiobutton throughout the recycler view. If 1st radio button in first item is checked and after that the user clicks on the 2nd radiobutton in 2nd item, then the 1st radiobutton in the 1st item should get unchecked.</p>
