title: TextView background is stretching
body: <p>I want to set background to a <code>TextView</code> and I want the size of the <code>TextView</code> to be in size of the background and the text.</p>
  
  <p>here's my code:</p>
  
  <pre><code>    &lt;TextView 
          android:id="@+id/attackeNameTextView"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_centerHorizontal="true"
          android:layout_marginTop="13dp"
          android:paddingTop="8dp"
          android:paddingLeft="35dp"
          android:paddingRight="35dp"
          android:singleLine="true"
          android:ellipsize="end"
          android:textSize="12sp"
          android:text="thej hhekj hejk hjkesd ks dkl jsalkj dkl"
          android:background="@drawable/attackee_name_background"/&gt; 
  </code></pre>
  
  <p>the outcome is, that the text fits inside the 'padding box' just fine, but the background is stretched.</p>
  
  <p>do I have to assign a fixed <code>layout_width</code> to the <code>TextView</code> ?</p>
