嵌套的RecyclerView不会显示

Question

我想创建一个带有NestedScrollView的RecyclerView，但RecyclerView不会显示。

这是我的XML布局：

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" 
    tools:context="com.yarkoni.anybody.activities.OffersActivity" 
    tools:showIn="@layout/activity_offers"> 

    <!-- A RecyclerView with some commonly used attributes --> 
    <android.support.v7.widget.RecyclerView 
     android:id="@+id/offerContent_recyclerView" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@android:color/holo_red_dark" 
     android:scrollbars="vertical" /> 
</android.support.v4.widget.NestedScrollView> 

这是我的活动：

final LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false); 
layoutManager.setAutoMeasureEnabled(false); 
offersRecyclerView.setLayoutManager(layoutManager); 

ArrayList<Offer> offerList = new ArrayList<>(); 
offerList.add(new Offer("Lorem")); 
offerList.add(new Offer("Lorem")); 
OffersAdapter offersAdapter = new OffersAdapter(offerList); 
offersRecyclerView.setAdapter(offersAdapter); 
offersRecyclerView.setNestedScrollingEnabled(false);

尝试通过给recyclerview固定的高度。
