NestedScrollView滚动延迟，直到CollapsingToolbarLayout视图不折叠

Question

您好我正在经历一种滞后时NestedScrollView滚动和观察这个滚动滞后，直到视图崩溃一旦视图折叠滚动工作正常。

有没有解决方案不是这个。

以下是XML代码

看来你需要使用this库。我认为它会解决你的问题。

为了完整起见，我张贴从上述文库例如采取的代码起见

<android.support.design.widget.CoordinatorLayout

    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_height="match_parent"> 

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

    <android.support.design.widget.CollapsingToolbarLayout 
     android:id="@+id/collapsing_toolbar_layout" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     app:layout_scrollFlags="scroll|exitUntilCollapsed"> 

     <android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar" 
     app:layout_collapseMode="pin"
