• 方式三

  final RefreshLayout refreshLayout = (RefreshLayout) findViewById(R.id.refreshLayout);
  // Header为贝塞尔雷达样式
  refreshLayout.setRefreshHeader(new BezierRadarHeader(this).setEnableHorizontalDrag(true));
  // Footer为球脉冲样式
  refreshLayout.setRefreshFooter(new BallPulseFooter(this).setSpinnerStyle(SpinnerStyle.Scale));
  

监听

刷新

taskStatisticsRl.setOnRefreshListener(new OnRefreshListener() {
    @Override
    public void onRefresh(RefreshLayout refreshLayout) {
                           
    }
});

加载

taskStatisticsRl.setOnLoadMoreListener(new OnLoadMoreListener() {
    @Override
    public void onLoadMore(RefreshLayout refreshlayout) {
                    
    }

刷新加载

taskStatisticsRl.setOnRefreshLoadMoreListener(new OnRefreshLoadMoreListener() {
    @Override
    public void onLoadMore(RefreshLayout refreshLayout) {

    }

    @Override
    public void onRefresh(RefreshLayout refreshLayout) {

    }
});

问题

显全部加载完并不再触发加载事件。
