Android SeekBar with limited enabled range

view story

http://stackoverflow.com – I've got effectively a media player. I want a SeekBar to both display and change the current point in the media. Some portion, maybe all maybe only part, of the media is currently loaded. I want to display the range that is loaded (and thus, the user can seek to) with the blue highlight that normally just displays to the left of the thumb. I specifically do not want a "range" selector with two thumbs. There's one thumb controlling one value: the current point of playback. What I want is a programmatically set range, from 0 to max which represents the entire media, that can be seeked to. (HowTos)
