小编Evo*_*ion的帖子

我是android的新手,我在屏幕方向改变时遇到了这个问题.fragment每当屏幕方向改变时,都会调用两次.以下是我的代码示例.我检查了其他帖子,但无法找到答案.任何人都指导我完成这个.

public class SampleFragment extends Fragment {

    static final String TAG_NAME = SampleFragment.class.getSimpleName();


    List<PhrToolBar> mToolBarList;


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

        DaggerHelper.getAppProviderComponent().inject(this);

        mRootView = null;

        getActivity().setTitle("Personal Health Records");

        mRootView = inflater.inflate(R.layout.sample_phr_main_fragment, container, false);

        mBinding = DataBindingUtil.bind(mRootView);
        mBinding.setViewModel(mViewModel);

        setHasOptionsMenu(true);

        return mRootView;

    }
