title: Seekbar - How can i unlink SecondaryProgress and Progress?
body: <p>i'd like to use a seekbar to show the current value and adjust the desired value. I managed to change the desired value via thumb (Progress) and the current value with the bar (SecondaryProgress). There is only one little bug/problem:</p>
  
  <p>When SecondaryProgress becomes lower than Progress, the bar shows the same value as Progress, even the value of SecondaryProgress really becomes lower or even 0 (checked that in debugger). </p>
  
  <p>What it should look like:</p>
  
  <pre><code>SecondaryProgress &lt; Progress   &lt;-- doesnt work, shows: 
  (====   O    )                               (=======O    )
  
  SecondaryProgress == Progress   &lt;-- works
  (=======O    )
  
  SecondaryProgress &gt; Progress   &lt;-- works
  (=======O==  )
  </code></pre>
  
  <p>Is there a setting that enables me to adjust that? Or do I have to customize the seekbar? And if so, where should i start? For me this doesnt look like a thing i can do in Layout...</p>
  
  <p>Thanks for your help</p>
