如何在嵌套滚动视图中适应包含布局

Question

我在 NestedScrollView 中包含 ConstraintLayout 但遇到问题。\n当布局包含其与父级高度不匹配时。它意味着 ConstraintLayout 的底部到最后一个子视图。

\n\n

这是我的约束布局：

这是我的主要布局：

你有解决方案吗？\n我的 ConstraintLayout 与父级不匹配，布局高度是换行内容。

尝试将其添加到您的NestedScrollView布局中

android:layout_height="match_parent"
android:fillViewport="true"
