ViewPager内的片段中的ScrollView不滚动

问题描述 投票:0回答:1

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"
