title: Add Multiple LinearLayout inside of another LinearLayout is not working as expected
body: <p>I have a LinearLayout which should contains a list of items (each item is a LinearLayout). 
   The problem is that the childs items (LinearLayouts) are not displayed one below another: just the fist one is visible. </p>
  
  <p>This is my layout.xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  </code></pre>
  
  <p></p>
  
  <pre><code>&lt;TextView

  <p>Do you know why this is happen? I thought that in a LinearLayout if there is not more available space on current line, the childs will be displayed on the next line. </p>
