滾動兩個recyclerView作爲一個

Question

我有兩個Recyclerview裏面NestedScrollView。第二個Recyclerview也有SwipeRefreshLayout。我嘗試爲兩個回收站設置一個滾動條，但我的解決方案沒有工作。兩個回收卷軸分開，我沒有解決方案，請幫助我。提前致謝。我的代碼

<android.support.v4.widget.NestedScrollView 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:fillViewport="true"> 
<RelativeLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 
    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/noFriendsTitle" 
     android:layout_marginTop="@dimen/marginTop" 
     android:layout_centerHorizontal="true" 
     android:visibility="gone" 
     android:text="@string/no_friends_title"/> 
    <ProgressBar 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/progressBarGetFriends" 
     android:layout_centerInParent="true"/> 
    <RelativeLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:id="@+id/mainFriendsRelative" 
     android:paddingTop="@dimen/marginTopSmall" 
     android:paddingBottom="@dimen/marginTopSmall" 
     android:visibility="invisible"> 
     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_marginStart="@dimen/paddingStart" 
      android:id="@+id/lastConversationTitle" 
      android:text="@string/friends_important_title"/> 
     <android.support.v7.widget.RecyclerView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:id="@+id/lastChatFriendsRecyclerView" 
      android:layout_below="@+id/lastConversationTitle" 
      android:layout_marginTop="@dimen/marginTopSmall"/> 
     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_marginStart="@dimen/paddingStart" 
      android:layout_below="@+id/lastChatFriendsRecyclerView" 
      android:layout_marginTop="@dimen/marginTopSmall" 
      android:id="@+id/allFriendsTitle" 
      android:text="@string/friends_all"/> 
     <android.support.v4.widget.SwipeRefreshLayout 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:id="@+id/friendSwipeToRefresh" 
      android:layout_below="@+id/allFriendsTitle" 
      android:layout_marginTop="@dimen/marginTopSmall"> 
      <android.support.v7.widget.RecyclerView 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:id="@+id/friendsRecyclerView" 
       android:scrollbars="vertical"/> 
     </android.support.v4.widget.SwipeRefreshLayout> 
    </RelativeLayout> 
</RelativeLayout> 

我的片段代碼

private void setLastConversationFriendsRecycler(RecyclerView lastConversationRecyclerView, List<Edge<Friends>> friends){ 
    lastConversationList.addAll(friends); 
    LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity()); 
    lastConversationRecyclerView.setHasFixedSize(true); 
    lastConversationRecyclerView.setLayoutManager(layoutManager); 
    lastConversationAdapter = new FriendsAdapter(getActivity(), lastConversationList, lastConversationRecyclerView); 
    lastConversationRecyclerView.setAdapter(lastConversationAdapter); 
} 

private void setFriendsRecycler(RecyclerView friendsRecyclerView, List<Edge<Friends>> friends){ 
    friendsList.addAll(friends); 
    LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity()); 
    friendsRecyclerView.setHasFixedSize(true); 
    friendsRecyclerView.setLayoutManager(layoutManager); 
    friendsAdapter = new FriendsAdapter(getActivity(), friendsList, friendsRecyclerView); 
    friendsAdapter.setOnLoadMoreListener(friendsListener); 
    friendsRecyclerView.setAdapter(friendsAdapter); 
} 

我也嘗試不同的組合setNestedScrollingEnabled，但結果是一樣的。

我已經找到了解決方案，我的代碼有什麼錯誤。這是工作代碼，也許有人有同樣的問題。
