Question

我有以下情况： NavigationDrawer创建一个Fragment来处理用户信息。 onCreateView（）上的片段调用Web Service并返回View。当Web服务完成回调分离和附加自身的片段。第二次在onCreateView（）上附加片段时，应创建一个包含用户信息的视图。但实际上发生的事情是View不会改变。

我错过了什么？

提前谢谢你，

片段代码：

private boolean mIsRefresh = false;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    // Gets Application Context
    mContext = getActivity().getApplicationContext();

    // Set up environment to use DataBase
    mGlobal = (Global) getActivity().getApplicationContext();
    mDAOFactory = mGlobal.getDAOFactory();

    mFragment = this;

    mFragmentView = inflater.inflate(R.layout.fragment_user_info, container, false);


    buildView();

    if (mIsRefresh) {
        return mFragmentView;
    }else {
        return null;
    }
}

这是buildView（）代码：

private void buildView() {

    mEtUserName = (EditText) mFragmentView.findViewById(R.id.userName);
    mEtUserEmail = (EditText) mFragmentView.findViewById(R.id.userEmail);
    mEtPassword = (EditText) mFragmentView.findViewById(R.id.password);
    mEtPasswordConfirmation = (EditText) mFragmentView.findViewById(R.id.passwordConfirmation);
    mIbSendPassword = (ImageButton) mFragmentView.findViewById(R.id.sendPassword);
    mAcUserCountry = (AutoCompleteTextView) mFragmentView.findViewById(R.id.userCountry);
    mEtUserState = (EditText) mFragmentView.findViewById(R.id.userState);
    mEtUserCity = (EditText) mFragmentView.findViewById(R.id.userCity);
    mEtUserPhoneNumberCountry = (EditText) mFragmentView.findViewById(R.id.userPhoneNumberCountry);
    mEtUserPhoneNumberCity = (EditText) mFragmentView.findViewById(R.id.userPhoneNumberCity);
    mEtUserPhoneNumber = (EditText) mFragmentView.findViewById(R.id.userPhoneNumber);
    mCbTCAccepted = (CheckBox) mFragmentView.findViewById(R.id.cbTCAccepted);


    // User has not been created
    if (mGlobal.getUserUID() == 0) {
        getUserEmail();
        getUserLocation();

    } else {
        if (mIsRefresh) {
            formatView();
        } else {
            getDataOnServer();
        }
    }

}

以下是调用Web Service的代码：

private void getDataOnServer () {

    mUserDAO = mDAOFactory.getUserDAO(mContext);

    final ProgressDialog progressDialog = ProgressDialog.show (getActivity(),
            getString(R.string.msgConnectingServer), getString(R.string.msgGettingData), true);

    //TODO Retirar o set abaixo
    mGlobal.setUserUID(1);

    mUserDAO.getUserByUID(mGlobal.getUserUID(), new Callback<User>() {
        @Override
        public void success(User user, Response response) {
            mUser = user;
            mIsRefresh = true;
            refresh();
        }

        @Override
        public void failure(RetrofitError error) {
            mUser = null;
            Log.e(getClass().getName(), "Retrofit Error = " + error);
            refresh();
        }

        private void refresh() {
            progressDialog.dismiss();
            FragmentManager fm = getFragmentManager();
            FragmentTransaction ft = fm.beginTransaction();
            ft.detach(mFragment)
                    .attach(mFragment)
                    .commit();

        }
    });
}

最后是onStart（）

@Override
public void onStart() {
    super.onStart();

    if (mIsRefresh) {
        mIsRefresh = false;
        getFragmentManager().beginTransaction()
                .remove(mFragment)
                .add(R.id.content_frame, mFragment)
                .commit();
    }

}

Answer 1

而不是

[packed=true]

这样做：

FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.detach(mFragment).attach(mFragment).commit();

重新加载片段无法正常工作
