title: Material design suggestions for lists with avatar, text and icon
body: <p>I want to create <code>Material Designed</code> Android application and I try to follow all Google's suggestions about making nice layouts specially for the new <code>RecylcerView</code>. The <code>RecyclerView</code> has avatar <code>ImageView</code>, title and subtitle <code>TextView</code> and action icon <code>ImageView</code>.</p>
  
  <p>What values should I put in ImageView's properites for <code>width</code> and <code>height</code> so it supports different screen sizes and densities, and what size of those drawables should I choose from the system icons pack?</p>
