Question

我正在开发MVP架构下的应用程序，我正在使用DataBinding。我有一个ViewPager，在第一个视图页面片段中有一些TexViews

这是我的第一个片段，在ViewPager中，有TextViews，请注意setText（）方法只适用于我的bind（）方法，但不适用于它。

public class ViewPagerFragmentMe extends BaseFragment implements ViewPagerFragmentMeView {

    private ViewPagerFragmentMePresenter mPresenter;
    private FragmentViewPagerMeBinding mFragmentBinding;
    private TextView mFollowers;
    private TextView mFollowing;
    private TextView mPost;


        @Override
        protected View getBindView(LayoutInflater inflater, ViewGroup container) {
            mFragmentBinding = DataBindingUtil.inflate(inflater,
                    R.layout.fragment_view_pager_me,container,false);
            View view = mFragmentBinding.getRoot();
            bind(mFragmentBinding);
            return view;
        }

        @Override
        protected void getPresenter() {
            Log.d(Constans.LOG,"GET PRESENTER CALLED");
            mPresenter = new ViewPagerFragmentMePresenterImpl(this);
            mFollowers.setText("2");//does not work
            startSocialCounterUp(3,mFollowers);
        }

        @Override
        public void startSocialCounterUp(int number, TextView textView) {
            mPresenter.onSetNumberCounterUp(number,textView);
            mFollowers.setText(String.valueOf(number));//does not work
        }

        private void bind(FragmentViewPagerMeBinding binder) {
            mFollowers = binder.textViewPagerFollowersNumber;
            mFollowing = binder.textViewPagerFollowingNumber;
            mPost = binder.textViewPagerPostNumber;
            mFollowers.setText("1");//works
        }
    }

这是我的BaseFragment

public abstract class BaseFragment extends Fragment {

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container,
                             @Nullable Bundle savedInstanceState) {
        View view = getBindView(inflater,container);
        getBindView(inflater, container);
        getPresenter();
        return view;
    }

    protected abstract View getBindView(LayoutInflater inflater, ViewGroup container);
    protected abstract void getPresenter();
}

最后我的MVP视图与片段相关

public interface ViewPagerFragmentMeView {
    void startSocialCounterUp(int number, TextView textView);
}

很奇怪。是不是？我做错了什么？

MVP下的ViewPager上的setTex没有效果
