title: Treate DENSITY_560 as XXXHIGH or XXHIGH?
body: <p>In the documents, android says:</p>
  
  <pre><code>/**
   * Intermediate density for screens that sit somewhere between
   * {@link #DENSITY_XXHIGH} (480 dpi) and {@link #DENSITY_XXXHIGH} (640 dpi).
   * This is not a density that applications should target, instead relying
   * on the system to scale their {@link #DENSITY_XXXHIGH} assets for them.
   */
  </code></pre>
  
  <p>Android think its a XXXHIGH(4X) screen.</p>
  
  <p>But I have another function call <code>getResources().getDimensionPixelSize(R.dimen.line_list_item_height)</code>,
   it returns 3X height, it is so strange, how to fix this?</p>
  
  <ul>
  <li>Device is Nexus 6p</li>
  <li>Compile sdk version is  23</li>
  <li>I use a viewpage inside a listview, so must calculate a height to prop up the  viewpage.</li>
  </ul>
