一.导入依赖

在app-module中添加RecycleView和SmartRefreshLayout的依赖

    //recyclerview
    implementation 'com.android.support:recyclerview-v7:26.1.0'
    implementation 'com.android.support:design:26.1.0'
    //SmartRefreshLayout
    implementation 'com.scwang.smartrefresh:SmartRefreshLayout:1.0.4-7'
    implementation 'com.scwang.smartrefresh:SmartRefreshHeader:1.0.4-7'

二.在mainActivity中添加xml布局

这是SmartRefreshLayout的基本布局，其中：

 app:srlAccentColor="#00000000"//设置Header主题颜色
 app:srlPrimaryColor="#00000000"//设置Footer主题颜色
 app:srlEnablePreviewInEditMode="true"//开启和关闭预览功能

三.MainActivity中初始化和刷新加载事件

  private RecyclerView mRecyclerView;
    private RefreshLayout mRefreshLayout;

    //初始化
    mRecyclerView=findViewById(R.id.rv);
    mRefreshLayout = findViewById(R.id.refreshLayout);

           //刷新
        mRefreshLayout.setOnRefreshListener(new OnRefreshListener() {
            @Override
            public void onRefresh(RefreshLayout refreshlayout) {
                mData.clear();
                mNameAdapter.notifyDataSetChanged();
                refreshlayout.finishRefresh();
            }
        });
        //加载更多
        mRefreshLayout.setOnLoadmoreListener(new OnLoadmoreListener() {
            @Override
            public void onLoadmore(RefreshLayout refreshlayout) {
                for(int i=0;i<30;i++){
                    mData.add("小明"+i);
                }
                mNameAdapter.notifyDataSetChanged();
                refreshlayout.finishLoadmore();
            }
        });

开启/关闭下拉刷新和加载更多，结束刷新和加载

开始下拉
mRefreshLayout.setEnableRefresh(true);//启用刷新
mRefreshLayout.setEnableLoadmore(true);//启用加载
关闭下拉
mRefreshLayout.finishRefresh();
mRefreshLayout.finishLoadmore();
