title: Click through a RecyclerView list item
body: <p>I have a <code>RecyclerView</code> with a <code>LinearLayoutManager</code> and an <code>Adapter</code>:</p>
  
  <pre><code>@Override public int getItemViewType(int position) {
      return position == 0? R.layout.header : R.layout.item;
  }
  </code></pre>
  
  <p>Here's <code>header.xml</code>:</p>
  
  <pre><code>&lt;View xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/header"
        android:layout_width="match_parent"
        android:layout_height="@dimen/header_height"
      /&gt;
  </code></pre>
  
  <p>What I want to achieve is to have a <strong>hole</strong> in the <code>RecyclerView</code> where I can click through to anything behind the <code>RecyclerView</code>. I tried a lot of combinations the following attributes to no avail:</p>
  
  <pre><code>      android:background="@android:color/transparent"
        android:background="@null"
        android:clickable="false"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:longClickable="false"
  </code></pre>
  
  <p><strong>How could I make the first item transparent (allowing touch events to anything behind it) in the list, but let it still occupy the space?</strong></p>
