In this post I’m going to address scroll state saving of nested RecyclerViews.
By default, if you scroll the parent RecyclerView, the nested RecyclerViews don’t save and restore state automatically.
A while ago, I released the 2.0 version of GravitySnapHelper with an extra goodie class called OrientationAwareRecyclerView.
I didn’t have the chance to properly explain the reason for that class, so I figured I would write some blog posts with some tips for nested RecyclerViews.
Since Material Design was introduced, Android has 3 main types of buttons:
According to the spec, the raised button definition is:
A typically rectangular material button that lifts and displays ink reactions on press.
But why should it lift? Does your finger work like a magnet? When you press any real button, the force you apply makes the button go down.
The 24.2.0 version of the support library introduced two new classes (SnapHelper and LinearSnapHelper) that should be used to handle snapping in a RecyclerView.
The support library 23.2.0 introduced a couple of classes to create BottomSheets, so I figured out we should have an easy way to setup a simple BottomSheet with some options.
