title: receiving error when inflating spinner layout
body: <p>So I am trying to set a custom image for my spinner drop down. I have went to a few stackoverflow questions and they all seem to have the same solution to get it done. For some reason when I try it I get this error <code>java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.plansly/com.example.plansly.planner}: android.view.InflateException: Binary XML file line #36: Binary XML file line #36: Error inflating class Spinner
