我试图在xml布局中滚动视图,其中包含recycleview和viewpager,但不知道nestedScrollView不会向上滚动视图。

布局文件。

export

Java文件

 <android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/swipe_refresh"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

我在StackOverFlow的帮助下找出了解决方案。我只使用ViewpagerRecycleView getItemViewType部分作为行项目,并删除了NestedScrollView,所以现在布局看起来像..

mainLayout.xml

  

<data>

    <variable
        name="MediaDiscoverFragmentNew"
        type="com.hpc.fragments.media.MediaDiscoverFragmentNew" />
</data>


<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/swipe_refresh"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">


    <android.support.v7.widget.RecyclerView
        android:id="@+id/rc_media"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />


</android.support.v4.widget.SwipeRefreshLayout>

为顶级Viewpager创建了两个单独的项目xmls raw_media_top.xml ,为其余项目创建了另一个 raw_media.xml

      if(viewType == HEADER_VIEW) {
        RawMediaTopBinding mediaTopBinding = 
        DataBindingUtil.inflate(mLayoutInflater, R.layout.raw_media_top, parent, false);
        mediaTopBinding.setMediaDiscoverAdapterNew(this);
        return new HeaderViewHolder(mediaTopBinding);
    } else {
        RawMediaBinding inspirationItemsBinding = DataBindingUtil.inflate(mLayoutInflater, R.layout.raw_media, parent, false);
        inspirationItemsBinding.setMediaDiscoverAdapterNew(this);
        return new ItemViewHolder(inspirationItemsBinding);
    }

干杯!
