java - 查找动态创建的 fragment 的内部 View

Question

我已动态地将一个 fragment 添加到另一个 fragment 。

我需要在该 fragment 中找到一些 View 。

我如何实现这一目标？

这是我的代码:

@Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState)
    {
        View view = inflater.inflate(R.layout.fragment_educational, container, false);

        if (view != null)
        {
            ButterKnife.inject(this, view);
        }


        DisposableEducationalFragment disposableEducationalFragment = new DisposableEducationalFragment();
        getChildFragmentManager().beginTransaction().add(R.id.fragmentContainer,disposableEducationalFragment).addToBackStack(null).commit();

我想在该动态 fragment 中找到这些 View :

howItWorks = (RelativeLayout) fragmentView.findViewById(R.id.HowItWorks);
            howWeHelp = (RelativeLayout) fragmentView.findViewById(R.id.HowWeHelp);
            knowYourBloodPressure = (RelativeLayout) fragmentView.findViewById(R.id.KnowYourBloodPressure);
            learnAboutBirthControl = (RelativeLayout) fragmentView.findViewById(R.id.LearnAboutBirthControl);

Answer 1

因此，将View view保存到临时变量中并稍后调用它。

tmpView = View ；

稍后的某个地方:

howItWorks = (RelativeLayout) tempView.findViewById(R.id.HowItWorks);

或者，也许，只是尝试一下:

howItWorks = (RelativeLayout) getActivity().findViewById(R.id.HowItWorks);
