API

Properties	Descrition	Type	Default
dataSource	An instance of ListView.DataSource to use	ListViewDataSource	-
initialListSize	How many rows to render on initial component mount.	number	-
onEndReached	Called when all rows have been rendered and the list has been scrolled to within onEndReachedThreshold of the bottom.	(event?) => {}	-
onEndReachedThreshold	Threshold in pixels (virtual, not physical) for calling onEndReached.	number	1000
pageSize	Number of rows to render per event loop.	number	1
renderHeader / renderFooter	The header and footer are always rendered (if these props are provided) on every render pass. If they are expensive to re-render, wrap them in StaticContainer or other mechanism as appropriate. Footer is always at the bottom of the list, and header at the top, on every render pass.	() => renderable	-
renderRow	Takes a data entry from the data source and its ids and should return a renderable component to be rendered as the row. By default the data is exactly what was put into the data source, but it's also possible to provide custom extractors. ListView can be notified when a row is being highlighted by calling highlightRow function.	(rowData, sectionID, rowID, highlightRow) => renderable	-
renderScrollComponent	A function that returns the scrollable component in which the list rows are rendered. Defaults to returning a ScrollView with the given props.	(props) => renderable	-
renderSectionHeader	If provided, a header is rendered for this section.	(sectionData, sectionID) => renderable	-
renderSeparator	If provided, a renderable component to be rendered as the separator below each row but not the last row if there is a section header below. Take a sectionID and rowID of the row above and whether its adjacent row is highlighted.	(sectionID, rowID, adjacentRowHighlighted) => renderable	-
scrollRenderAheadDistance	How early to start rendering rows before they come on screen, in pixels.	number	1000
contentContainerStyle	These styles will be applied to the scroll view content container which wraps all of the child views.	Object	-
horizontal	When true, the scroll view's children are arranged horizontally in a row instead of vertically in a column.	bool	false
onContentSizeChange	Called when scrollable content view of the ScrollView changes.	(contentWidth, contentHeight) => {}	-
onScroll	Fires at most once per frame during scrolling. The frequency of the events can be controlled using the scrollEventThrottle prop.	e => {}	-
scrollEventThrottle	This controls how often the scroll event will be fired while scrolling	number	50
onLayout	Invoked on mount and layout changes with	({nativeEvent:{ layout:{ width, height }}}) => {}	-
----
renderBodyComponent (web only)	render listview body wrapper component	() => renderable	-
renderSectionWrapper (web only)		render listview section wrapper component	(sectionID) => renderable
renderSectionBodyWrapper (web only)	render listview section body wrapper component	(sectionID) => renderable	-
useBodyScroll (web only)	use html body's scroll	bool	false
pullToRefresh (web only)	Whether enable pullToRefresh, you need use it with rmc-pull-to-refresh	bool	false

Methods

• getMetrics() - Exports some data, e.g. for perf investigations or analytics.
• scrollTo(...args) - Scrolls to a given x, y offset(not support smooth animation).

ListView.IndexedList

This component is often used in the "Contacts" / "city list" scenes, support for index navigation.

You can use almost all APIs on the ListView.

Note: Only two-step rendering is supported, so that the first screen priority display can be achieved, but if the list data volume is too large, the overall performance will still be affected.

Properties	Descrition	Type	Default
quickSearchBarTop	top button object of navigation bar	object{value:string, label:string}	{ value: '#', label: '#' }
quickSearchBarStyle	quickSearchBar's style	object	-
onQuickSearch	fire on clicking navigation bar.	(sectionID: any, topId?:any) => void	-
showQuickSearchIndicator	whether show quick search indicator	bool	false
delayTime	delay rendering time setting (for the first screen optimization, the initial rendering of the number of initialListSize data, after which time rendering the remaining data items, ie totalRowCount - initialListSize)	number	100ms
delayActivityIndicator	the loading indicator for delayed rendering.	react node	-

Tips

ListView has two types of scroll containers:

1. Partial div container
   • default, note: need to manually set the height of the ListView
2. html body container
   • set useBodyScroll to take effect (do not need to set height)

please see 0.11.0 upgrade tips.

变量 “prevDataBlob” 被使用却未被声明

当使用 rowHasChanged 方法对比数据是否有变化时， 第一个参数使用到了 prevDataBlob变量，该变量从哪里取到的呢？
