title: Weight proportions not respected in nested LinearLayout
body: <p>I have a code like this:</p>
  
  <pre><code>...
      &lt;LinearLayout
         android:layout_width="fill_parent" 
         android:layout_height="wrap_content"
         android:weightSum="10"&gt;
  
      &lt;LinearLayout
          android:layout_width="fill_parent" 
          android:layout_height="wrap_content" 
          android:layout_weight="1" /&gt; 
  
      &lt;LinearLayout
          android:layout_width="fill_parent" 
          android:layout_height="wrap_content" 
          android:layout_weight="8"&gt; 
  
      &lt;TextView android:id="@+id/text2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/&gt;
  
      &lt;/LinearLayout&gt;
  
      &lt;LinearLayout
          android:layout_width="fill_parent" 
          android:layout_height="wrap_content" 
          android:layout_weight="1" /&gt; 
  
       &lt;/LinearLayout&gt;
  ...
  </code></pre>
  
  <p>This code is nested in other linearlayout's which have the same weightSum and weight.
  The SDK I use is 1.6 Android. I cannot figure out why the amount of space assigned to the elements with weight equal to 1 is different if I remove the <code>TextView</code> in the middle. It seems that even if the Text size (number of chars) of the <code>TextView</code> are more, the <code>LinearLayout</code>s with weight 1 got's smaller .. How is this possible?</p>
