问题
I'd like to make a custom scrollbar for one of my scrollview, and impossible to find how to do.
I want my scrollbar to be more visible, and controllable like the fastScroll of the ListViews. Unfortunately there is no setFastScrollEnabled(true) on the ScrollView.
\o/ So say welcome to my two first questions :
How to change the scrollbar appearence?
How to activate fast scrolling on a ScrollView?
Then another idea come to me : adding buttons and indicators on the scrollbar, as a goToTop and a goToBottom, a progressBar, etc... and so making this little bar an ergonomic tool for users. (for exemple a expandable contextual menu)
So if the first questions have good answers, I've a second step question :
How to add buttons and setOnClickListener this new ScrollBar?
To illustrate it :
On the left : FastScroll on ScrollView
On the right : ErgonomicScrollBar on ScrollView
An image to illustrate it
