A scrollable time range picker, easy to understand and use.
It's a well built fragment, you can use it by new a fragment and set it's configurations like scrollSpeedand isTimeRangeDraggable(more features on the way).
You can also set OnTimeRangeChangeListener to do your own things like saving the time figure and update your own UI.
For I don't have enough time to make it a libary, so you have to import this project as a module or just add java files into your own projects, in that way, you also need to add propereties references into your strings.xml,styles.xml,dimens.xml,intergers.xml,colors.xmllike what I do in my project, then you can use it by newing the fragment.
I know adding reference lines is annoying, maybe in the future I'll post it in a more efficient way.
