我使用一个片段来显示cardview,并为所有片段提供一个公共底部导航。在这里,根据我的数据,我有超过5张卡,但我无法滚动查看所有卡。只能向上滚动到第二张卡,由于底部导航,第二张卡也不完全可见。 main_activity.xml

<?xml version="1.0" encoding="utf-8"?>

    android:paddingTop="20dp">



    <fragment
        android:id="@+id/nav_host_fragment"

然后回顾

        </LinearLayout>

请检查我的代码并帮我解决这个问题。

这是错误的,在你的main\u activity.xml中,碎片
android:layout\u over=“@id/nav\u view”
,它用于相对论。使用
app:layout\u constraintBottom\u toTopOf=“@id/nav\u view”
。这将解决第二个问题(由于底部导航,第二个问题也不完全可见)

ScrollView
更改为
NestedScrollView

在cardview内容中,您不需要ConstraintLayout,LinearLayout作为根元素就足够了(删除ConstraintLayout,因为您没有利用其平面视图层次结构的功能)。如果您的LinearLayout背景可以移动到MaterialCardView的背景,那么您也不需要LinearLayout

对于您的recyclerview,通过xml或代码将
nestedScrollingEnabled
设置为
false
。试试这些东西,它会解决你的问题
