3 个解决方案

#1

You can use NestedScrollView instead of ScrollView. and please replace Listview with RecyclerView.

您可以使用NestedScrollView而不是ScrollView。请将Listview替换为RecyclerView。

you can find example from here

你可以从这里找到例子

NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.

NestedScrollView就像ScrollView一样，但它支持在新旧版本的Android上充当嵌套滚动父级和子级。默认情况下启用嵌套滚动。

#2

In your LinearLayout, child of the ScrollView, change android:layout_height="match_parent" to android:layout_height="wrap_content".

在您的LinearLayout，ScrollView的子项中，将android：layout_height =“match_parent”更改为android：layout_height =“wrap_content”。

That will makes this container being greater than a screen.

这将使该容器大于屏幕。

Then, unfortunately, having a vertical sliding component in a ScrollView is never a good idea. If the ListView is not populated by changing the layout_height, try to add the comments manually like findviewbyid(R.id.xxx).addView(adapter.getView(...)). Of course, it is not the real code, but that's the idea.

然而，遗憾的是，在ScrollView中使用垂直滑动组件绝不是一个好主意。如果未通过更改layout_height来填充ListView，请尝试手动添加注释，如findviewbyid（R.id.xxx）.addView（adapter.getView（...））。当然，这不是真正的代码，但这就是主意。

Put Only one attribute on scroll view.

在滚动视图上只放置一个属性。

Like Only one Linear Layout in Scroll view and All other Attribute on Linear Layout.

类似于滚动视图中的一个线性布局和线性布局上的所有其他属性。
