title: RecyclerView inside HorizontalScrollView Android
body: <p>I am using a Recycler view inside a Horizontal Scroll View to display threaded comments like below:</p>
  
  <blockquote>
    <p>Comment1
        Comment1Child1
        Comment1Child2
              Comment1Child2Child1
        Comment1Child3 Comment2</p>
  </blockquote>
  
  <p>etc.</p>
  
  <p>I have done this with the following XML:</p>
  
  <pre><code>&lt;HorizontalScrollView
                  android:id="@+id/horizontalScrollView"
                  android:layout_width="match_parent"
                  android:layout_height="wrap_content"
                  android:fillViewport="true"
                  android:scrollbarSize="2dp"&gt;
  
                  &lt;android.support.v7.widget.RecyclerView
                      android:id="@+id/commentRV"
                      android:layout_width="match_parent"
                      android:layout_height="wrap_content"
                      android:layout_alignParentStart="true"
                      android:layout_marginLeft="47dp"
                      android:minWidth="200dp" /&gt;
              &lt;/HorizontalScrollView&gt;
  </code></pre>
  
  <p>You'll see I set a min width of 200dp so that the comments never get too small and the deeper down the thread they go the further off screen it will be pushed.</p>
  
  <p>It is displaying perfectly but I am unable to scroll horizontally. I can see the scroll bars but I cannot scroll horizontally.</p>
  
  <p>I have fiddled with disabling Touch and nestedScrollingEnabled in the RV but not sure what the real solution is. Nothing seems to work?</p>
  
  <p>Any help would be much appreciated! Thank you</p>
