在android中使用fragment时如何管理onActivityResult()

// 在父Activity中重写onActivityResult()方法
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // 获取当前显示的Fragment实例
    FragmentManager fragmentManager = getSupportFragmentManager();
    Fragment fragment = fragmentManager.findFragmentById(R.id.container); // 使用容器的ID来替换

    if (fragment != null) {
        // 获取子Fragment的FragmentManager实例
        FragmentManager childFragmentManager = fragment.getChildFragmentManager();

        // 获取所有直接嵌套在子Fragment中的子Fragment列表
        List<Fragment> childFragments = childFragmentManager.getFragments();

        // 遍历子Fragment列表，调用子Fragment的onActivityResult()方法
        if (childFragments != null) {
            for (Fragment childFragment : childFragments) {
                if (childFragment != null) {
                    childFragment.onActivityResult(requestCode, resultCode, data);
                }
            }
        }
    }
}
