QuickReturnHeader is a tiny Android library that implements the popular "quick return" design pattern for lists and scrollable content in general. In this pattern, which can be found for instance in the Google Keep app, the header hides as soon as we start scrolling down, and reappears inmediately (regardless of how far down the list we are) as soon as we scroll up again.
You can use WaveSideBar in the contacts page of your application.
