title: wrap_content does not work for TextView in Android 4.0
body: <p>I have a LinearLayout that contains 2 TexView with layout_height set to <strong>wrap_content</strong>. Normally if the TextView does not contain any data, its Height becomes 0 (that's what wrap_content does). This works as expected in Android 3.2, but in Android 4.0, it leaves an empty space !!
  Any explanation please?</p>
  
  <pre><code>&lt;LinearLayout
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:orientation="vertical"&gt; 
  
      &lt;TextView
          android:id="@+id/tv_1"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:textSize="25sp"
          android:textStyle="bold" /&gt;
  
      &lt;TextView
          android:id="@+id/tv_2"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:textSize="25sp"
          android:textStyle="bold" /&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
