Question

我有一个带有AppBar的ConstraintLayout，2个片段（每个片段包含一个RecyclerView）和一个底部导航。问题在于底部导航与RecyclerView的最后一行重叠。

这是我的布局

对于SwipeRefreshLayout，它什么也不做。

有什么问题的想法吗？

请将刷新刷新pattern = re.compile(r'-?\d*\.\d+') output = [item for item in lst if not pattern.fullmatch(item)]修改为*app:layout_constraintTop_toBottomOf="@+id/AppBar"，将app:layout_constraintTop_toBottomOf="@id/AppBar"修改为app:layout_constraintBottom_toTopOf="@id/+BottomNavigationLayout"，最后，将SwipeRefreshLayout的高度设置为0dp，以使其使用match_constraint， app:layout_constraintBottom_toTopOf="@id/BottomNavigationLayout"
