下拉刷新上拉加载控件PullToRefresh

1、添加依赖

    //下拉刷新
    //https://github.com/823546371/PullToRefresh
    implementation 'com.jwenfeng.pulltorefresh:library:1.2.7'

2、添加控件

<?xml version="1.0" encoding="utf-8"?>
<com.jwenfeng.library.pulltorefresh.PullToRefreshLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- 内容控件 有且只能有一个 -->
    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

      
    </ScrollView>

</com.jwenfeng.library.pulltorefresh.PullToRefreshLayout>

3、设置监听
查找控件后设置监听

@BindView(R.id.activity_main)
PullToRefreshLayout pullToRefreshLayout;

pullToRefreshLayout.setRefreshListener(new BaseRefreshListener() {
            @Override
            public void refresh() {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                
                        // 结束刷新
                        pullToRefreshLayout.finishRefresh();
                    }
                }, 2000);
            }

            @Override
            public void loadMore() {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                    
                        // 结束加载更多
                        pullToRefreshLayout.finishLoadMore();
                    }
                }, 2000);
            }
        });

结束刷新前处理刷新问题，结束加载前处理加载问题，我看到的资料是2016年，刚开始感觉太老了，刷新一搜一大堆，但是用起来还不错
