title: Android ScrollView Scrollbar Size
body: <p>I'm using a ScrollView and I want to set the ScrollBar size, but everything I tried failed.
  I tried with attribute android:scrollbarSize, with style, with the theme but nothing. The size of the scrollbar it's always the same.
  Any suggestions? Thanks</p>
  
  <p>I tried with this: </p>
  
  <pre><code>&lt;ScrollView 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent"
      android:layout_marginTop="10px"
      android:layout_marginBottom="15px"
      android:scrollbarSize="20px"
      android:scrollbarTrackVertical="@drawable/scrollbar_reflection"
      android:scrollbarThumbVertical="@drawable/scrollbar_state2"&gt;
  </code></pre>
  
  <p>but the width of the Scrollbar doesn't change.</p>
  
  <p>So I created a style file like this:</p>
  
  <pre><code>&lt;resources&gt;
      &lt;style name="ShowAllScrollBar1"&gt;
          &lt;item name="android:scrollbarSize"&gt;20px&lt;/item&gt;           
      &lt;/style&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>and then set style in AndroidManifest.</p>
