RecyclerView Scroll to specified location (Kotlin)

Var mShouldScroll:Boolean = false var mShouldScroll:Boolean = false var mShouldScroll:Boolean = false  smoothMoveToPosition(mRecyclerView: RecyclerView, position: Int) {/ / position of the first visible var firstItem = mRecyclerView getChildLayoutPosition (mRecyclerView. GetChildAt (0)) / / the last visible position var lastItem = mRecyclerView. GetChildLayoutPosition (mRecyclerView. GetChildAt (mRecyclerView. ChildCount - 1)) If (position < firstItem){// If (position < firstItem){ SmoothScrollToPosition can jump straight mRecyclerView. SmoothScrollToPosition (position)} else if (position < = lastItem) {/ / SmoothScrollToPosition does not move at all, Var movePosition = position-Firstitem if (movePosition >= 0 && movePosition<mRecyclerView.childCount){ var top = mRecyclerView.getChildAt(movePosition).top MRecyclerView. SmoothScrollBy (0, top)}} else {/ / if you want to jump the position after the last visible items, Call smoothScrollToPosition to scroll to visible location and onScrollStateChanged to call smoothMoveToPosition again. Execute on a judgment method of mRecyclerView. SmoothScrollToPosition (position) mToPosition = position mShouldScroll = true}}Copy the code
