我写了这样的xml，但如何在主要活动中调用它，需要在列表视图后显示卡片视图。在我的主要活动欢迎帖子不可见。我需要在列表视图末尾显示从我的数据库中获取的布局

您可以使用scrollView
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
// layout content
</ScrollView>
有关详细信息，请参阅此link

替换此
<ListView
android:id="@+id/post"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@null"
android:visibility="gone" />
用
<ListView
android:id="@+id/post"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@null"
android:layout_above="@+id/udyopro_post"
android:visibility="gone" />
也替换此
<RelativeLayout
android:layout_below="@+id/post"
android:id="@+id/udyopro_post"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="gone">
用这个
<RelativeLayout
android:layout_alignParentBottom="true"
android:id="@+id/udyopro_post"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="gone">
