我已经使用了这个很棒的扩展(写在kotlin，但也可以在Java中使用)

https://github.com/Widgetlabs/expedition-nestedscrollview

基本上你在任何包中都有NestedRecyclerView比如在项目中的utils，然后创建你的recyclerview

 <com.your_package.utils.NestedRecyclerView
      android:id="@+id/rv_test"
      android:layout_width="match_parent"
      android:layout_height="match_parent" />

看看Marc Knaup写的这篇很棒的文章

我必须实现带有工具栏滚动的CoordinatorLayout，这花了我一整天的时间。我已经通过移除NestedScrollView工作了。我只是在根处使用RelativeLayout。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/rv_nearby"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior" />

</RelativeLayout>

简单地添加recyclerView.setNestedScrollingEnabled(false);在setAdapter本身为我工作之前。我没有添加app:layout_behavior="@string/appbar_scrolling_view_behavior"任何地方&没有设置任何自定义布局管理器

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

        <LinearLayout

                android:text="Some Text..."
                android:padding="15dp" />

        </LinearLayout>

        <LinearLayout

                android:textSize="16sp"/>

            <View

                android:layout_height="1dp"
                android:background="#efefef"/>

                </LinearLayout>




            </LinearLayout>

        </androidx.core.widget.NestedScrollView>
    </LinearLayout>

</layout>

这里使用recyclerview的属性

app:layout_behavior="@string/appbar_scrolling_view_behavior"

并像这样关闭recyclerview嵌套滚动

android:nestedScrollingEnabled="false"

如果您使用的是RecyclerView-23.2.1或更高版本。下面的解决方案可以很好地工作:

在你的布局中添加这样的RecyclerView:

<android.support.v7.widget.RecyclerView
        android:id="@+id/review_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:scrollbars="vertical" />

在你的java文件中:

RecyclerView mRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
LinearLayoutManager layoutManager=new LinearLayoutManager(getContext());
layoutManager.setAutoMeasureEnabled(true);
mRecyclerView.setLayoutManager(layoutManager);
mRecyclerView.setHasFixedSize(true);
mRecyclerView.setAdapter(new YourListAdapter(getContext()));

这里layoutManager.setAutoMeasureEnabled(真正的);会成功的。

查看这个问题和这个开发者博客以获得更多信息。

你可以使用android:fillViewport="true"来让NestedScrollView测量RecyclerView。RecyclerView将填充剩余的高度。所以如果你想滚动NestScrollView，你可以设置RecyclerView的minHeight。
