Android Question smooth scrollbar position

[adastra]

i want to change the position of scrollbar smoothly. i am using timer to move positon but it is not smooth
can any one help

That's going to depend on what the scroll bar is doing. Is it reactive, i.e. moving as a result of processing in the app, or is the movement of the scrollbar driving the processing?

If you can move the scroll bar at an interval close to 40ms (equates to 25 frames per second) it should be very smooth, but if the app is doing a lot of processing in between, it may not be possible.

Do you have some code you can show that will help understanding?
