Question

我正在使用此功能滚动到水平回收站视图中的选定位置。问题是，如果我滚动回收器，然后单击某个项目，则它不会到达视图的中心。相反，如果我不滚动回收站，它将起作用。当我单击一个项目时，我正在使用此方法。该位置是adapterPosition。

override fun scrollToSelected(position: Int, isLeftScroll: Boolean) {
if(!isLeftScroll || position == 0) contactRV.layoutManager?.smoothScrollToPosition(contactRV, RecyclerView.State(), position +1)
    else contactRV.layoutManager?.smoothScrollToPosition(contactRV, RecyclerView.State(), position-1)

我该怎么做才能解决此问题？

您将实现[ERROR] : Script Error Couldn't find module: /com.alcoapps.socialshare/com.alcoapps.socialshare for architecture: x86_64的方法RecyclerView.SmoothScroller。

onTargetFound(View, State, Action)

特别是在/** * Called when the target position is laid out. This is the last callback SmoothScroller * will receive and it should update the provided {@link Action} to define the scroll * details towards the target view. * @param targetView The view element which render the target position. * @param state Transient state of RecyclerView * @param action Action instance that you should update to define final scroll action * towards the targetView */ abstract protected void onTargetFound(View targetView, State state, Action action);和LinearLayoutManager中：

LinearSmoothScroller

Android smoothScrollToPosition无法正常工作
