title: Shape dashed line, dash doesn't work
body: <p>I want to make dashed line using <code>shape</code>.</p>
  
  <p>This is my XML:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item&gt;
          &lt;shape android:shape="line"&gt;
              &lt;stroke android:color="@color/grey_divider"
                  android:width="1dip"
                  android:dashWidth="5dip"
                  android:dashGap="13dip"/&gt;
          &lt;/shape&gt;
      &lt;/item&gt;
  &lt;/selector&gt;
  </code></pre>
  
  <p>On my device I see this:
