title: Android - How to add a dashed/dotted separator line for RecyclerView?
body: <p>I have used the code from <a href="https://stackoverflow.com/a/31243174/1617737">this answer</a> to create a solid separator line for my <code>RecyclerView</code>s.</p>
  
  <p>However, I would like the line to be dashed/dotted.</p>
  
  <p>I already have a <code>line_dashed.xml</code> resource that I am using elsewhere in my app:</p>
  
  <pre><code>&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"
         android:shape="line" &gt;
  
      &lt;stroke
          android:color="@color/blue"
          android:dashGap="12dp"
          android:dashWidth="12dp"
          android:width="1dp" /&gt;
  
  &lt;/shape&gt;
  </code></pre>
  
  <p>But if I try applying this as the drawable resource that is accessed via my call to <code>recyclerView.addItemDecoration(new SimpleDividerItemDecoration(getContext()))</code>, no line is drawn at all.</p>
  
  <p>How to solve so a dashed line is shown?</p>
