title: LinearLayout doesn't show view
body: <p>I'm using a <code>LinearLayout</code> that doesn't show every view.</p>
  
  <p>This is the xml-code:</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="160dp"
      android:layout_height="wrap_content"
      android:orientation="horizontal"
      tools:context="de.schumann_connection.yahtzee.DescriptionColumnFragment"&gt;
  
      &lt;View
          android:layout_width="1dp"
          android:layout_height="match_parent"
          android:background="#FF000000" /&gt;
  
      &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:tools="http://schemas.android.com/tools"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:orientation="vertical"
          tools:context="de.schumann_connection.yahtzee.DescriptionColumnFragment"&gt;
  
          &lt;View
              android:layout_width="match_parent"
              android:layout_height="1dp"
              android:background="#FF000000" /&gt;
          &lt;TextView
              android:layout_width="wrap_content"
              android:layout_height="43dp"
              android:text=""/&gt;
          &lt;View
              android:layout_width="match_parent"
              android:layout_height="1dp"
              android:background="#FF000000" /&gt;
      &lt;/LinearLayout&gt;
  
      &lt;View
          android:layout_width="1dp"
          android:layout_height="match_parent"
          android:background="#FF000000" /&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>There are much more controls contained but this is enough to demonstrate the problem.</p>
  
  <p>This should draw a black rectangle. But the right vertical line is missing.
  Why?</p>
