我想實現一個水平滾動RecyclerView裏面的另一個RecyclerView這意味着父RecyclerView中的父RecyclerView（垂直滾動）和子RecyclerView（水平滾動）。我提到了有關這個要求的幾個問題，並從這個問題How to have a ListView/RecyclerView inside a parent RecyclerView?找到了一個更好的解決方案，並且成功實施。 在子適配器的佈局文件編輯後，子RecyclerView的滾動功能被禁用。Android RecyclerView滾動不工作後佈局編輯
這是我的代碼， 這是父母的片段。
public class MarketFragment extends Fragment {
private String log = "abcpappaHomeFragment";
private Button loadMore ;
private ArrayList<ProductCategoryBean> productCategoryList=null;
private ProductCategoryService productCategoryService;
private RecyclerView.Adapter mAdapter;
private RecyclerView mRecyclerView;
private LinearLayoutManager mLayoutManager;
public MarketFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
productCategoryService = new ProductCategoryService();
productCategoryList =(ArrayList<ProductCategoryBean>)productCategoryService.getAllCategories();
View rootView = inflater.inflate(R.layout.market_fragment, container, false);
mRecyclerView = (RecyclerView)rootView.findViewById(R.id.market_recycle_list);
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(getContext());
mRecyclerView.setLayoutManager(mLayoutManager);
mAdapter = new MarketRecyclerAdapter(getContext(),productCategoryList,this);
mRecyclerView.setAdapter(mAdapter);
return rootView;
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
}
@Override
public void onDetach() {
super.onDetach();
}
}
這是LayoutFile
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

<android.support.v7.widget.RecyclerView
android:id="@+id/market_recycle_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="4dp" />

ChildCustomLinearLayoutManager是通過pptang在上述問題提供的同一類。 其實我是android的新手，如果你曾經交叉過這樣的問題，讓我知道我犯的錯誤。謝謝你們。
謝謝asnad你救了我的一天。其作品 –
