title: Android RecyclerView change all item imageviews
body: <p>I have a RecyclerView  with some items.
  <br/>
  I want to change all ImageView image on items (without scroll)
  <br/>
  My part code in onBindViewHolder is : 
  <br/></p>
  
  <pre><code>int count = parent.getChildCount();
  v = parent.getChildAt(position);
  while(i&lt;count)
     if (i != position) {
        v = parent.getChildAt(i);
        ImageView imageView1 = (ImageView) v.findViewById(R.id.imgPlaySound);
        imageView1.setImageResource(R.mipmap.playsound);
        LinearLayout linearSeek1 = (LinearLayout) v.findViewById(R.id.linearSeek);
        linearSeek1.setVisibility(View.GONE);
     }
     i++;
  }
  </code></pre>
  
  <p>This part code is working fine but if I add some items to my RecyclerView and scrolling my items my code cannot access to my all items
  <br/>
  My custom RecyclerView class is separate file of activity code </p>
