SmartRefreshLayout上拉刷新下拉加载

首先导入依赖

//SmartRefreshLayout的依赖
    implementation 'com.scwang.smartrefresh:SmartRefreshLayout:1.0.4-6'

在需要刷新的写入控件

<com.scwang.smartrefresh.layout.SmartRefreshLayout
        android:id="@+id/smartrefresh"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    <com.scwang.smartrefresh.layout.header.ClassicsHeader
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/xrecycler"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"></android.support.v7.widget.RecyclerView>
    </com.scwang.smartrefresh.layout.SmartRefreshLayout>

在MainActivity中初始化然后写入方法

smartrefresh.setOnRefreshListener(new OnRefreshListener() {
            @Override
            public void onRefresh(RefreshLayout refreshlayout) {
                results.clear();
                page =1;
                shoppingPresenter.load(page);
                shopAdapter.notifyDataSetChanged();
                refreshlayout.finishRefresh();
            }
        });
        smartrefresh.setOnLoadmoreListener(new OnLoadmoreListener() {
            @Override
            public void onLoadmore(RefreshLayout refreshlayout) {

                page ++;
                shoppingPresenter.load(page);
                shopAdapter.notifyDataSetChanged();
                refreshlayout.finishLoadmore();
            }
        });
