BaseQuickAdapter上拉加载下拉刷新2

上一中方法，条件太多，比较复杂，现在再写一种implements OnRefreshListener, OnLoadMoreListener的方法。
首先，类必须实现OnRefreshListener, OnLoadMoreListener。

public class AListFragment implements OnRefreshListener, OnLoadMoreListener

重写两种方法：onLoadMore（加载更多），onRefresh（刷新）

在获取到数据的时候，

                    if (RechargeListBean == null || RechargeListBean.size() == 0) {//没有获取到数据
                        return;
                    }

                    if (RechargeListBean.size() < PAGE_SIZE) {//获取的数据小于一页
                        // 禁止上拉
                        mRefreshLy.setEnableLoadMore(false);
                    } else {
                        //大于等于1页，可以上拉
                        mRefreshLy.setEnableLoadMore(true);
                    }
                    //mLoaderMore为false时，没有下拉，此时数据messageDatas可以清空再在下面addAll。
                    //为true时，说明有下拉数据，不用清空，在下面addAll的是下一页（++page）的数据。
                    if (!mLoaderMore) {
                        messageDatas.clear();
                    }

                    stopRefresh(false);
                    stopLoadMore();
                    messageDatas.addAll(RechargeListBean);
                    mRechargeListItemAdapter.setNewData(messageDatas);

具体代码：

public class AListFragment extends BaseFragment implements View.OnClickListener, OnRefreshListener, OnLoadMoreListener {

    static final int PAGE_SIZE = 15;

    int page = 1;

    // 刷新
    private boolean mRefreshing = false;
    // 加载更多
    private boolean mLoaderMore = false;

    // 显示的数据集合
    private ArrayList<RechargeListBean> messageDatas = new ArrayList<>();

    private RefreshHeader mRefreshHeader;

    RechargeListItemAdapter mRechargeListItemAdapter;

    @BindView(R.id.ly_pull_refresh)

    @BindView(R.id.recharge_list)

    @BindView(R.id.iv_goback)
    ImageView iv_goback;


    @Override
    public void onLazyInitView(@Nullable Bundle savedInstanceState) {
        super.onLazyInitView(savedInstanceState);
        ImmersionBar.with(this).titleBar(R.id.ly_title_bar).autoDarkModeEnable(true).statusBarColor(R.color.color_white).init();
        iv_goback.setOnClickListener(this);

        mRefreshHeader = getRefreshHeader();
        mRefreshLy.setEnableRefresh(true);
        mRefreshLy.setHeaderHeight(50);
        mRefreshLy.setRefreshHeader(mRefreshHeader);
        mRefreshLy.setEnableRefresh(true);
        mRefreshLy.setOnRefreshListener(this);
        mRefreshLy.setOnLoadMoreListener(this);
        mRefreshLy.setEnableLoadMore(true);
        mRefreshLy.setFooterHeight(50);

        mRechargeListItemAdapter = new RechargeListItemAdapter(null);
        mRechargeListItemAdapter.setEmptyView(new YJGEmptyView(getContext(), YJGEmptyView.TYPE_ORDER));

        mRechargeListRV.setAdapter(mRechargeListItemAdapter);
        Log.v("re22","0000===");
        selectBill(page);
    }

    public void selectBill(int page){
        showLoading();

        RetrofitClient.getInstance().getApiService()
                .getRechargeList(page,PAGE_SIZE)
                .map(new ResultTransformFunction<>())
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(RechargeListBean -> {
                    hideLoading();

                    if (RechargeListBean == null || RechargeListBean.size() == 0) {
                        return;
                    }

                    if (RechargeListBean.size() < PAGE_SIZE) {
                        // 禁止上拉
                        mRefreshLy.setEnableLoadMore(false);
                    } else {
                        mRefreshLy.setEnableLoadMore(true);
