我在一个活动中有一个tablayout和一个viewpager,在viewpager内,我正在显示一个带有scrollview的片段作为其根布局,由于某种原因它没有滚动。我一直在努力使其工作数小时,但到目前为止仍无任何效果,请提供帮助。
这是我的活动:

您可以尝试在AppBarLayout之外获取ViewPager标签吗?因此,您的活动xml应该类似于:
<CoordinatorLayout>
<AppBarLayout>
//...
</AppBarLayout>
<ViewPager>
//...
</ViewPager>
</CoordinatorLayout>
并且不要忘记将此属性添加到您的视图寻呼机:
app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior"
