ScrollView 和 ConstraintLayout 在底部留下一个巨大的白色 space
ScrollView and ConstraintLayout leave a huge white space at the bottom
我正在设计一个设置屏幕。由于可能有很多选项，我将 ConstraintLayout 包装在 ScrollView 中。但是，底部有一个巨大的白色space，我无法摆脱。我已经按照有关该主题的许多其他答案的建议将 fillViewPort="true" 添加到 ScrollView。
这是我的布局文件：

结果：
初始画面
完全滚动
看来你设置的约束有误。使用 ConstraintLayout 创建 xml 时要小心，注意不能相互连接的视图。这意味着出了点问题。
我复制了您的代码并重新连接了所有约束。对我来说，现在没有底space

我正在设计一个设置屏幕。由于可能有很多选项，我将 ConstraintLayout 包装在 ScrollView 中。但是，底部有一个巨大的白色space，我无法摆脱。我已经按照有关该主题的许多其他答案的建议将 fillViewPort="true" 添加到 ScrollView。
这是我的布局文件：

看来你设置的约束有误。使用 ConstraintLayout 创建 xml 时要小心，注意不能相互连接的视图。这意味着出了点问题。 我复制了您的代码并重新连接了所有约束。对我来说，现在没有底space
