title: ScrollView inside RecyclerView won't scroll
body: <p>I want to make a <code>LinearLayout</code> (to which I'm adding items dynamically) scrollable inside a scrollable <code>RecyclerView</code>. On startup, I can see a little scrollbar initially (indicating it's a scrollable view, fades in seconds). Tried appCompat NestedScrollView as well as enabling <code>nestedScrollingEnabled</code>, with no success. How can I make the <code>LinearLayout</code> scrollable inside the <code>RecyclerView</code>?</p>
  
  <pre><code>&lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"&gt;
    &lt;ScrollView
        android:layout_width="wrap_content"
        android:layout_height="300dp"
        android:fillViewport="true"
        android:nestedScrollingEnabled="true"&gt;
        &lt;LinearLayout
            android:id="@+id/playerlist_linear"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="left|center_vertical"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginTop="5dp"
            android:layout_marginBottom="7dp"
            android:orientation="vertical"&gt;
        &lt;/LinearLayout&gt;
    &lt;/ScrollView&gt;
  
  &lt;/FrameLayout&gt;
  </code></pre>
  
  <p>RecyclerView code</p>
  
  <pre><code>&lt;android.support.v7.widget.RecyclerView
      android:id="@+id/messagesListView"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_gravity="bottom"
      android:layout_weight="1"
      android:nestedScrollingEnabled="false"/&gt;
  </code></pre>
  
  <p>UPDATE: I found out that scrolling does indeed work, but only if I spam the mouse or tap really fast inside the scrollview. It kind of gets focused and allows scrolling as long as mouse is held down. Really strange.</p>
