title: how to update data in recyclerview item from another item?
body: <p>I have a problem with <code>RecyclerView</code>, I have <code>RecyclerView</code> which has a <code>radio button</code> and few other views in each row item,</p>
  
  <p>What I wanted exactly is, when a <code>RadioButton</code> is checked by user I want to uncheck other <code>RadioButton</code>(if anything is checked earlier). Since it is a <code>Recyclerview</code> I cannot use radiogroup.</p>
  
  <p>In the adapter <code>onBindViewHolder</code> I write this listener for each radio button</p>
  
  <pre><code>  holder.radioButton.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              selectedPosition = holder.getAdapterPosition();
              Toast.makeText(activity, "section: " + selectedPosition, Toast.LENGTH_SHORT).show();
          }
      });
  </code></pre>
  
  <p>how can i make previous radio button selected uncheck?<br>
  in other words, how can i update view property in specific item of recyclerview from another item view listener?</p>
