java - 显示具有相同类型适配器的多个 RecyclerView

问题描述

我试图在同一个片段中显示 3 个 RecyclerView，每个 RecyclerView 显示不同类型的匹配（已完成匹配、本周匹配和尚未匹配）。

我已经实例化了 3 个 RV 和 3 个适配器，如下面的代码所示：

matchesList_rv_finished = view.findViewById(R.id.finished_upcoming_matches_rv);
    matchesList_rv_finished.setHasFixedSize(true);
    LinearLayoutManager layoutManager1 = new LinearLayoutManager(view.getContext(), LinearLayoutManager.HORIZONTAL, false);
    matchesList_rv_finished.setLayoutManager(layoutManager1);

    matchesList_rv_Week = view.findViewById(R.id.Week_upcoming_matches_rv);
    matchesList_rv_Week.setHasFixedSize(true);
    LinearLayoutManager layoutManager2 = new LinearLayoutManager(view.getContext(), LinearLayoutManager.HORIZONTAL, false);
    matchesList_rv_Week.setLayoutManager(layoutManager2);

    matchesList_rv_NotYet = view.findViewById(R.id.NotYet_upcoming_matches_rv);
    matchesList_rv_NotYet.setHasFixedSize(true);
    LinearLayoutManager layoutManager3 = new LinearLayoutManager(view.getContext(), LinearLayoutManager.HORIZONTAL, false);
    matchesList_rv_NotYet.setLayoutManager(layoutManager3);

    matchAdapter1 = new MatchAdapter();
    matchAdapter2 = new MatchAdapter();
    matchAdapter3 = new MatchAdapter();

这就是我接收 3 个匹配列表并设置 3 个适配器的方式：

Model.instance.getUpComingMatches(new Model.MatchListener() {
        @Override
        public void onComplete(ArrayList<Match> finishedMatches,
                               ArrayList<Match> thisWeekMatches,
                               ArrayList<Match> notYetMatches) {
            finishedMatchList = finishedMatches;
            matchAdapter1.setMatchesData(finishedMatchList);
            matchesList_rv_finished.setAdapter(matchAdapter1);
            
            ThisWeekMatchList = thisWeekMatches;
            matchAdapter2.setMatchesData(ThisWeekMatchList);
            matchesList_rv_Week.setAdapter(matchAdapter2);
            
            NotYetMatchList = notYetMatches;
            matchAdapter3.setMatchesData(NotYetMatchList);
            matchesList_rv_NotYet.setAdapter(matchAdapter3);
            
        }
    });

我不确定我做错了什么，但似乎最后一个适配器覆盖了前 2 个适配器的数据，而不是在每个 RV 中显示 3 个不同的匹配项：

我想我在这里缺少一些基本信息，或者也许只有一种更简单的方法来实现这一点？谢谢您的帮助！
