ScrollView在Android中不起作用
[英]ScrollView doesn't work in Android
问题描述
I have a fragment that contains a view pager, a recycler view, etc. I want to place all of that inside a scroll view , but it just refuses to scroll. 
我有一个包含视图寻呼机，回收站视图等的片段。我想将所有这些放在滚动视图中，但它只是拒绝滚动。 Am I missing something here? 我在这里错过了什么吗？ I've tried setting fillViewport false, and removing the scrollbars:none, and a couple of other things but nothing helps.. 我已经尝试设置fillViewport false，并删除滚动条：无，以及其他一些东西，但没有任何帮助..
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:scrollbars="none">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:id="@+id/headerLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:orientation="horizontal"
android:gravity="center_vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="abc"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/image"/>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:layout_below="@id/headerLayout"
android:id="@+id/recyclerView"
android:scrollbars="none"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<android.support.v4.view.ViewPager
android:layout_below="@id/recyclerView"
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content">

</android.support.v4.view.ViewPager>

As I responded in comment, check the adapter class of RecyclerView . 正如我在评论中回答的那样，检查RecyclerView的适配器类。 I won't be explaining it as it is too big to explain. 我不会解释它，因为它太大而无法解释。 But for starters follow the link Recyclerview and handling different type of row inflation 但对于初学者来说，请点击Recyclerview链接并处理不同类型的行通胀
