RecyclerView smoothScrollToPosition()无法与nestedScrollView一起使用。每当创建片段时,我都想滚动到底部

问题描述 投票:0回答:1

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

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)
 }
