xrecyclerview 下拉刷新上拉加载

依赖

implementation 'com.jcodecraeer:xrecyclerview:1.3.2'
implementation 'com.android.support:design:27.1.0' 解决编译有误

写入适配器

//刷新
public  void refresh(List temlist){
    this.list.clear();
    this.list.addAll(temlist);
}
//加载更多
public  void loadMore(List list){
    this.list.addAll(list);
    notifyDataSetChanged();
}

写在MainActivivy
