当片段开始时,我只是试图将RecyclerView移到最后一个位置,但是找不到解决方案。当在数据库中插入新的“ Pagina”时,下面的代码可以正常工作,它将移动到最后一个位置。但是,如果我关闭然后重新打开,它将回到顶部。那么,如何在创建片段时使平滑滚动工作?
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
appDatabase = AppDatabase.getDatabase(requireContext())
val smoothScroller = object : LinearSmoothScroller(context) {
override fun getVerticalSnapPreference(): Int = SNAP_TO_START
}
viewModelo = ViewModelProviders.of(this).get(ViewModelo::class.java)
// Create the observer which updates the UI.
val listPaginas = Observer <List<Pagina>> {
// Update the UI, in this case, a TextView.
recyclerViewAdapter?.addItens(it)
if (it.size < 1) {
smoothScroller.targetPosition = it.size
} else {
smoothScroller.targetPosition = it.size-1
}
recyclerView?.layoutManager?.startSmoothScroll(smoothScroller)
}
viewModelo?.todasPaginas()?.observe(this, listPaginas)
}

尝试以下更改,它可以正常工作!
A.CallTo(() => fakeFoo.AccessTheWebAsync2(
A<List<SpecialString>>.That.IsSameSequenceAs(result)))
.Returns(5);
