高性能的简单列表组件，支持下面这些常用的功能：
完全跨平台。
支持水平布局模式。
行组件显示或隐藏时可配置回调事件。
支持单独的头部组件。
支持单独的尾部组件。
支持自定义行间分隔线。
支持下拉刷新。
支持上拉加载。
如果需要分组/类/区（section），请使用 SectionList
ItemSeparatorComponent：分割线组件，
ListFooterComponent：结尾组件
ListHeaderComponent：头组件
data：列表数据
horizontal：设置为true则变为水平列表。
numColumns：列数 组件内元素必须是等高的,无法支持瀑布流布局
columnWrapperStyle：numColumns大于1时，设置每行的样式
getItemLayout：如果我们知道行高可以用此方法节省动态计算行高的开销。
refreshing：是否正在加载数据
onRefresh：设置此属性需要一个标准的 RefreshControl 控件，刷新数据
renderItem：渲染每个组件
onViewableItemsChanged：当一个新的Item渲染或者隐藏 的时候调用此方法。参数：info: {viewableItems: Array, changed: Array} viewableItems：当前可见的Item，changed：渲染或者隐藏的Item。
scrollToEnd({params?: ?{animated?: ?boolean}})：滚动到末尾，如果不设置getItemLayout属性的话，可能会比较卡。
scrollToIndexparams: {animated?: ?boolean, index: number, viewPosition?: number}：滚动到制定的位置
scrollToOffset(params: {animated?: ?boolean, offset: number})：滚动到指定的偏移的位置。import React, {Component} from 'react';
