用ListSwipeRefreshLayout实现安卓listView下拉刷新，上拉加载

二级列表做完例子

1、XML布局

<com.android.mgwaiter.view.ListSwipeRefreshLayout
        android:id="@+id/srl_swipe_refresh_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/list_tasking_color">

        <ExpandableListView
            android:id="@+id/task_expandablelistview"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#00FFFFFF"
            android:divider="@null" />

</com.android.mgwaiter.view.ListSwipeRefreshLayout>

2、刷新方法

private void swipeRefresh() {
        // 设置顶部下拉刷新
        srl_swipe_refresh_layout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                reLoadList();
                getTaskInfoStatic();    //网络请求
            }
        });
        // 设置底部上拉加载更多
        srl_swipe_refresh_layout.setOnLoadListener(new ListSwipeRefreshLayout.OnLoadListener() {
            @Override
            public void onLoad() {
                page++;
                getTaskInfoStatic();
            }
        });
    }

/**
     *list清除数据
     */
    private void reLoadList() {
        if (dataList != null) {
            dataList.clear();
            page = 1;
            mealExpandableListAdapter.refresh();
        }

    }

3、上拉加载更多自定义ListSwipeRefreshLayout
