如何删除 constraintlayout 和 include 层之间的 space?

how can i remove space between constraintlayout and include layers?

我想去掉图片中的白色 space Picure

我在图片上画了白色的红圈space 我想删除它 我在 Whosebug 中搜索,但在那种情况下我找不到任何答案。

我的主要布局是 --> toolbar_normal.xml:

我该怎么做? 谢谢

删除文件 city_detail_act.xml 中的以下行父标记应该可以修复它

android:paddingBottom="65dp"

并将这些添加到您的包含标签

android:layout_width="match_parent"
android:layout_height="match_parent"

另外,考虑像这样 UI 使用底部导航布局。

首先删除这个:

android:paddingBottom="65dp"

那么你的include应该是这样的:

<include
    android:id="@+id/content"
    layout="@layout/city_detail_act"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    app:layout_constraintBottom_toTopOf="@id/tolbar_storyButton"
    app:layout_constraintTop_toTopOf="parent" />
