我的 xml 由一个约束布局组成。这里面有 2 个按钮和 1 个嵌套的 ScrollView 。 ScrollView 中有各种元素,包括回收 View 。我希望回收 View 不滚动,而只滚动嵌套的 ScrollView 。我在这种模式下禁用了回收 View 的滚动(recyclerView.setNestedScrollingEnabled(false);)但问题是嵌套 ScrollView 不滚动。你能帮助我吗?我附上下面的代码。

代码以这种模式开始:

最佳答案

正如我在评论中的回答

对于其他面临同样问题的人。这可能会有所帮助。

由于某些原因,ScrollView 在包含 ConstraintLayout 时不会滚动。

对于解决方法,我们可以在 ScrollView 中使用 LinearLayoutRelativeLayout 而不是 ConstraintLayout。或者

由于 OP 确实将 ConstraintLayout 放在 Linear or Relative Layout 中,所以达到了目的。
