我有一个RecyclerView
,我创建了一个标题。当我按下键盘时,当我尝试单击EditText
时,键盘会隐藏标题。 ListView
的{{1}}部分显示完美,但RecyclerView
没有显示,当我尝试向上滚动时,操作栏也没有显示。我试图将RecyclerView header
包裹在RecyclerView header
中,但似乎没有效果。我知道我无法将ScrollView
包裹在RecyclerView
中,因为这会导致嵌套垂直ScrollView
,因为ScrollViews
已经有内置RecyclerView
。任何帮助,将不胜感激。谢谢!

如您所见,如果我尝试向上滚动,则隐藏第一张图像的标题。
