我有一个嵌套的滚动视图,在其中有一个图像视图和一个回收站视图。每当调用onResume()片段方法时,我都希望回收站视图一直滚动到底部。当前行为是它像正常屏幕一样打开屏幕,并且根本没有滚动。
我尝试了各种解决方案,但没有任何效果。
这是用于布局和Fragment类的代码。请帮我。没事

override fun onResume() {
super.onResume()
mainActivity.supportActionBar?.title = args.name
recyclerViewTrnsaction.layoutManager = LinearLayoutManager(activity)
launch {
context?.let {
val transactions = getAllTransactions(args.id)
recyclerViewTrnsaction.adapter = TransactionAdapter(transactions)
nestedScrollView.smoothScrollTo(0, nestedScrollView.height)
recyclerViewTrnsaction.smoothScrollToPosition(recyclerViewTrnsaction.adapter!!.itemCount)
}
}
}
尝试使用此滚动NestedScrollView
而不是RecyclerView
。
将平滑的滚动代码替换为
nestedScrollView.post {
nestedScrollView.fullScroll(View.FOCUS_DOWN)
}
