问题 I have a class which implements expandable list activity . In the XML code (or I can do it in java), I set fastScrollEnabled to true . This does in deed enable fast scroll.

问题 I am using GridLayoutManager with recyclerview, when i fast scroll down one item out of four visible grid items (bottom right ) is moved further down, I am using this tutorial to implement fast scroll and fast scroll indicator here 回答1: Guess i've found the solution.

Its source code shows an interesting field: /** * Current decoration state, one of: * <ul> * <li>{@link #STATE_NONE}, nothing visible * <li>{@link #STATE_VISIBLE},
