下拉刷新上拉加载第三方框架

依赖

implementation 'com.scwang.smartrefresh:SmartRefreshLayout:1.0.3'
    implementation 'com.scwang.smartrefresh:SmartRefreshHeader:1.0.3'
           

布局

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

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

java代码获取id 设置点击事件

smartrefresh.setOnRefreshListener(new OnRefreshListener() {
    @Override
    public void onRefresh(RefreshLayout refreshlayout) {

        smartrefresh.finishRefresh();//时间
        initData();//数据
    }
});
smartrefresh.setOnLoadmoreListener(new OnLoadmoreListener() {
    @Override
    public void onLoadmore(RefreshLayout refreshlayout) {
   smartrefresh.finishLoadmore();
    }
});
