Vertical android seekbar from 0 to max starting from the top

view story

http://stackoverflow.com – I'm using the following class to draw a vertical seekbar: http://560b.sakura.ne.jp/android/VerticalSlidebarExample.zip As shown in the answer of the following question: How to make a vertical SeekBar in Android? All though this works perfectly, I would like to display the vertical seekbar the other way around. Starting with 0 and then going down to the max value, as opposed to having to seek upwards towards the max value. I have tried adjusting the rotation of the seekbar on draw, but with no luck: protected void onDraw(Canvas c) { c.rotate(-90); // Tried chaging this to 90 (HowTos)
