title: SwipeRefreshLayout setRefreshing() not showing indicator initially
body: <p>I have a very simple layout but when I call <code>setRefreshing(true)</code> in <code>onActivityCreated()</code> of my fragment, it does not show initially.</p>
  
  <p>It only shows when I do a pull to refresh. Any ideas why it isn't showing up initially?</p>
  
  <p><strong>Fragment xml:</strong></p>
  
  <pre><code>&lt;android.support.v4.widget.SwipeRefreshLayout
      android:id="@+id/swipe_container"
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;ScrollView
          android:layout_width="match_parent"
          android:layout_height="match_parent"&gt;
  
          &lt;RelativeLayout
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:orientation="vertical"&gt;
  
          &lt;/RelativeLayout&gt;
