title: how to scroll pull to refresh scrollview in normal scrollview
body: <p>Here is my layout xml.</p>
  
  <pre><code>&lt;ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:id="@+id/garae_scroll"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:background="@color/background"
  android:fillViewport="true"
  android:focusableInTouchMode="false" &gt;
     &lt;RelativeLayout&gt;
        ...
        &lt;com.handmark.pulltorefresh.library.PullToRefreshScrollView&gt;
           &lt;LinearLayout/&gt;
        &lt;/com.handmark.pulltorefresh.library.PullToRefreshScrollView&gt;
     &lt;/RelativeLayout&gt;
  &lt;/ScrollView&gt;
  </code></pre>
  
  <p>I already tried the solution in this link:
  <a href="https://stackoverflow.com/questions/4490821/scrollview-inside-scrollview">ScrollView Inside ScrollView</a></p>
  
  <p>However, it didn't work.  How can do use child PullToRefreshScrollView??
  Please help me.</p>
