title: How to vertical scroll in Android Activity
body: <p>I have the following layout:</p>
  <pre><code>&lt;LinearLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
      android:layout_width=&quot;fill_parent&quot;
      android:layout_height=&quot;fill_parent&quot;
      android:isScrollContainer=&quot;true&quot;
      android:orientation=&quot;vertical&quot;&gt;
  
      &lt;Gallery
          android:id=&quot;@+id/gallery&quot;
          android:layout_width=&quot;fill_parent&quot;
          android:layout_height=&quot;wrap_content&quot;
          android:gravity=&quot;bottom&quot; /&gt;
  
      &lt;LinearLayout
          android:id=&quot;@+id/chart&quot;
          android:layout_width=&quot;fill_parent&quot;
          android:layout_height=&quot;wrap_content&quot;
          android:layout_weight=&quot;1&quot;
          android:orientation=&quot;horizontal&quot; /&gt;
      
  &lt;/LinearLayout&gt;
  </code></pre>
  <p>Gallery is filled at runtime and when the user taps on an item I fill the LinearLayout with a series of images.<br />
  I would like to scroll vertically but if I add a ScrollView when the user taps the Gallery the LinearLayout is not filled anymore.</p>
  <p>Is it normal? How can I add a vertical scroll?</p>
