我想在视图组中显示所有文本视图后画一条线。我面临的问题是它抛出一个错误 scrollview can have only one direct child。但我试图在最后划清界限。怎么做？当我在模拟器上 运行 时，我的图像视图也不可见。

该错误说明了您不能将多个视图作为直接子视图放置到滚动视图中。您将线性布局和视图直接放在滚动视图中。它只能有一个视图作为直接子视图。所以附上你最外层的线性布局并在另一个垂直方向的线性布局中查看
试试这个

你可以给ScrollView添加background(#000000)属性和paddingButtom来实现这个功能，最后一个视图就不需要了。
您不能在滚动视图中添加两个单独的子视图。这就是它给出例外的原因。

删除ImageView的layout_weight属性，像这样：
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageView4"
android:src="@drawable/ic"
android:layout_marginRight="10dp"/>

我想在视图组中显示所有文本视图后画一条线。我面临的问题是它抛出一个错误 scrollview can have only one direct child。但我试图在最后划清界限。怎么做？当我在模拟器上 运行 时，我的图像视图也不可见。

该错误说明了您不能将多个视图作为直接子视图放置到滚动视图中。您将线性布局和视图直接放在滚动视图中。它只能有一个视图作为直接子视图。所以附上你最外层的线性布局并在另一个垂直方向的线性布局中查看
试试这个

你可以给ScrollView添加background(#000000)属性和paddingButtom来实现这个功能，最后一个视图就不需要了。
您不能在滚动视图中添加两个单独的子视图。这就是它给出例外的原因。

删除ImageView的layout_weight属性，像这样：
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageView4"
android:src="@drawable/ic"
android:layout_marginRight="10dp"/>
