title: android.view.InflateException: Binary XML file line #9: Error inflating class <unknown>
body: <p>I've been looking into this issue for hours and similar errors that had solutions didn't do the trick.</p>
  
  <p>I'm reusing this XML file for multiple ListViews in different activities (which I'm assuming has something to do with it) but I do not see why it would break. The XML file represents the individual items in the ListView.</p>
  
  <p>Here's the XML:</p>
