title: Recycler View repeats background colour
body: <p>I have a songs list in recycler view. and i need to change the background colour of rows previously played.</p>
  
  <p>so in my <code>onBindViewHolder</code> i have this.</p>
  
  <pre><code>               if(activeAudioIndex &gt; activeList.indexOf(currentSong)) {
                      currentRow.setBackgroundColor(R.color.colorPink)
                  }
  </code></pre>
  
  <p>in this <code>activeAudioIndex</code> is the actual index of playing song.</p>
  
  <p><code>activeList</code> is the array used for recyclerView </p>
  
  <p>But i can see changed background colours repeating for unnecessary rows. when i scroll down.</p>
  
  <p>HOW TO FIX THIS ISSUE ?</p>
