我正在开发网球应用程序,我想在这里展示现场比分锦标赛(可扩展的 Recyclerview) 我在这里添加了一个屏幕截图

想要达到这样的成绩

我正在将此库用于可扩展的 recyclerview这里我不知道如何在可扩展中添加自定义子数据和父数据。

我复制了这个样本,但我不知道该怎么做。我解析这个 json 看这里

      if (responseString != null) {

                try {
                    String tournament = null, home_player = null, home_player_point = null, away_player = null, away_player_point = null,HomeOne=null,AwayOne=null,HomeTwo=null,AwayTwo=null,HomeThree=null,AwayThree=null,HomeFour=null,AwayFour=null,HomeFive=null,AwayFive=null;

                    JSONObject MainObject = new JSONObject(responseString).getJSONObject("list").getJSONObject("Sport").getJSONObject("2").getJSONObject("Matchday").getJSONObject("2016-08-20").getJSONObject("Match");

//                    Log.d("", "onPostExecute: jObject = " + MainObject);

                    Iterator<String> keys = MainObject.keys();
                    while (keys.hasNext()) {
                        String MatchNoKey = keys.next();
                        Log.v("list MatchNoKey = ", MatchNoKey);

                        JSONObject MatchNoObj;

                        if(MainObject.get(MatchNoKey) instanceof JSONObject) {

                            MatchNoObj = MainObject.getJSONObject(MatchNoKey);
                            String id = MatchNoObj.getString("id");
                            String leagueType = MatchNoObj.getString("leagueType");
                            String startTime = MatchNoObj.getString("startTime");
                            String status = MatchNoObj.getString("status");
                            String leagueCode = MatchNoObj.getString("leagueCode");
                            Log.v("details", "id = " + id + ", " + "leagueType = " + leagueType + ", " + "startTime = " + startTime + ", " + "status = " + status + ", " + "leagueCode = " + leagueCode );
//                            after complete matchno object info
//                            now we get the home Object
                            if(MatchNoObj.has("Home")) {

                                JSONObject HomeObj = MatchNoObj.getJSONObject("Home");

                                Log.d(TAG, "onPostExecute: Home pass");

                                String id_home = HomeObj.getString("id");
                                home_player = HomeObj.getString("name");
                                String serve = HomeObj.getString("serve");

                                Log.v("details", "id_home = " + id_home + ", " + "player0ne = " + home_player + ", " + "serve = " + serve );

                            }

//                            Away Object
                            if(MatchNoObj.has("Away")){

                                JSONObject AwayObj = MatchNoObj.getJSONObject("Away");

                                Log.d(TAG, "onPostExecute: Away pass");

                                String id_away = AwayObj.getString("id");

                                    String[] score = CurrentScore.split("-");

                Toast.makeText(getApplicationContext(), "Couldn't get Data from server", Toast.LENGTH_SHORT).show();
            }

        }

这是我的样本

我不知道如何在其中添加子数据。因为我在孩子中有多个数据。

Ingredient beef = new Ingredient("beef");
    Ingredient cheese = new Ingredient("cheese");
    Ingredient salsa = new Ingredient("salsa");
    Ingredient tortilla = new Ingredient("tortilla");
    Ingredient ketchup = new Ingredient("ketchup");
    Ingredient bun = new Ingredient("bun");

    Recipe taco = new Recipe("taco", Arrays.asList(beef, cheese, salsa, tortilla));
    Recipe quesadilla = new Recipe("quesadilla", Arrays.asList(cheese, tortilla));
    Recipe burger = new Recipe("burger", Arrays.asList(beef, cheese, ketchup, bun));
    final List<Recipe> recipes = Arrays.asList(taco, quesadilla, burger);

    RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
    mAdapter = new RecipeAdapter(this, recipes);
    mAdapter.setExpandCollapseListener(new ExpandableRecyclerAdapter.ExpandCollapseListener() {
        @Override
        public void onListItemExpanded(int position) {
            Recipe expandedRecipe = recipes.get(position);

            String toastMsg = getResources().getString(R.string.expanded, expandedRecipe.getName());
            Toast.makeText(MainActivity.this,
                    toastMsg,
                    Toast.LENGTH_SHORT)
                    .show();
        }

        @Override
        public void onListItemCollapsed(int position) {
            Recipe collapsedRecipe = recipes.get(position);

            String toastMsg = getResources().getString(R.string.collapsed, collapsedRecipe.getName());
            Toast.makeText(MainActivity.this,
                    toastMsg,
                    Toast.LENGTH_SHORT)
                    .show();
        }
    });

    recyclerView.setAdapter(mAdapter);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));

    new GetLiveData().execute();
}

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    mAdapter.onSaveInstanceState(outState);
}

@Override
protected void onRestoreInstanceState(@NonNull Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    mAdapter.onRestoreInstanceState(savedInstanceState);
}

这是我的 POJO

你可以用这个库来实现它,这里有一个完整的例子。

基本上,您将项目分组为几个部分:

class MySection extends StatelessSection {

    String header;
    List<MatchNoObj> list;
    boolean expanded = true;

    public MySection(String header, List<MatchNoObj> list) {
        // call constructor with layout resources for this Section header and items 
        super(R.layout.section_header, R.layout.section_item);
        this.myHeader = header;
        this.myList = list;
    }

    @Override
    public int getContentItemsTotal() {
        return expanded? list.size() : 0;
    }

    @Override
    public RecyclerView.ViewHolder getHeaderViewHolder(View view) {
        return new HeaderViewHolder(view);
    }

    @Override
    public void onBindHeaderViewHolder(RecyclerView.ViewHolder holder) {
        final HeaderViewHolder headerHolder = (HeaderViewHolder) holder;

        headerHolder.tvTitle.setText(title);

        headerHolder.rootView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                expanded = !expanded;
                headerHolder.imgArrow.setImageResource(
                        expanded ? R.drawable.ic_keyboard_arrow_up_black_18dp : R.drawable.ic_keyboard_arrow_down_black_18dp
                );
                sectionAdapter.notifyDataSetChanged();
            }
        });
    }

    @Override
    public RecyclerView.ViewHolder getItemViewHolder(View view) {
        // return a custom instance of ViewHolder for the items of this section
        return new MyItemViewHolder(view);
    }

    @Override
    public void onBindItemViewHolder(RecyclerView.ViewHolder holder, int position) {
        MyItemViewHolder itemHolder = (MyItemViewHolder) holder;

        // bind your view here
        MatchNoObj matchNoObj = list.get(position);
        itemHolder.tvItem.setText(matchNoObj.leagueName);
    }
}

然后创建您的部分的实例并设置您的适配器:

// Create an instance of SectionedRecyclerViewAdapter 
SectionedRecyclerViewAdapter sectionAdapter = new SectionedRecyclerViewAdapter();

// Add your Sections
sectionAdapter.addSection(new MySection("Western Southern Open - Cincinnati", westernSouthernMatchList));
sectionAdapter.addSection(new MySection("US Open", usOpenMatchList));

// Set up your RecyclerView with the SectionedRecyclerViewAdapter
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
recyclerView.setAdapter(sectionAdapter);
