setSelectedMinValue and setSelectedMaxValue wont call OnRangeSeekBarChangeListener about range-seek-bar HOT 2 OPEN

This could be considered a feature. If you're changing them manually you might 
as well call onRangeSeekBarChange(...) yourself. You may actually *want* to 
change the value without the listener being called in some circumstances. I 
don't know though.

Ok, I had the same trouble...  I agree with your idea that it's a kind of 
feature, but it would at least be more convenient if the listener inside 
RangeSeekBar were public instead of private, so you could more easily call a 
refresh, or just have a refresh function or something.  Usually a seekbar wants 
to trigger other code.
