[游戏开发]Android 中Fragment之间传递数据

布局如图，外面是一个父fragment（即黑线部分，我们称它为fragment4），上面有两个按钮，点左边按钮fragment5，就会在下面content 布局处切换到fragment5的内容，如果点上面右边按钮fragment6，则会在content处显示fragment6 的内容。所以父类fragment4和fragment5之间怎么传递数据呢，fragment4 和fragment6之间怎么传递数据呢。

在frgment4页面添加changeFragment代码

  public void changeFragment(int flag) {
        flag2 = flag;
        if (flag == FRAGMENT_FLAG1) {
            binding.title.titleTab.setTabIndex(flag);
            transactionsTab5Fragment = new TransactionsTab5Fragment();
            transactionsTab6Fragment = null;
            if (!transactionsTab5Fragment.isAdded()) {
                Bundle bundle = new Bundle();
                bundle.putString("Type", type);
                transactionsTab5Fragment.setArguments(bundle);
                getChildFragmentManager().beginTransaction().replace(R.id.content, transactionsTab5Fragment).commitAllowingStateLoss();
            }

        } else if (flag == FRAGMENT_FLAG2) {
            binding.title.titleRight.setVisibility(View.VISIBLE);
            binding.title.titleRightImg.setVisibility(View.VISIBLE);
            binding.title.titleTab.setTabIndex(flag);
            transactionsTab6Fragment = new TransactionsTab6Fragment();
            transactionsTab5Fragment = null;
            if (!transactionsTab6Fragment.isAdded()) {
                Bundle bundle = new Bundle();
                bundle.putString("Type", type);
                transactionsTab6Fragment.setArguments(bundle);
                getChildFragmentManager().beginTransaction().replace(R.id.content, transactionsTab6Fragment).commitAllowingStateLoss();
            }
        }
    }

?主要代码：

Bundle bundle = new Bundle();
bundle.putString("Type", type);
transactionsTab5Fragment.setArguments(bundle);

在fragment5页面这样接收数据：

 @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        ctx = getActivity();
        if (getArguments() != null) {
            financeType = getArguments().getString("Type");
        }

        
    }
