autoLoadMore bool Yes false when the value is true, pull up load more will be auto
onRefresh func Yes when refreshing, this function will be called
onLoadMore func Yes when loadingMore, this function will be called
onEndReachedThreshold number Yes 0 threshold in pixels (virtual, not physical) for calling onLoadMore
pullUpDistance number Yes 35 determines the pull up max distance
pullUpStayDistance number Yes 50 determines the pull up stay distance
pullDownDistance number Yes 35 determines the pull down max distance
pullDownStayDistance number Yes 50 determines the pull down stay distance
enabledPullUp bool Yes true when the value is false, pull up load more will be disabled
enabledPullDown bool Yes true when the value is false, pull down refresh will be disabled
listItemProps object Yes see react-native documents
renderRowWithVisibility bool Yes when the value is true, the children of the listRow can be controlled with 'hidden' state
pageTop number Yes 0 determines the top relative to the page of the float section header(sticky header) view

Special Props

  • listItemProps: when set this prop, listView will use special 'listRow', the listRow will remove its children to release memory when its position is outside viewport of device, and will undo when its position is inside viewport of device. Usually it is used with 'react-native-smart-image-loader'

  • renderRowWithVisibility: when the value is true, the children of the listRow can be controlled with 'hidden' state. This prop is valid when 'listItemProps' is being set, and it is only valid for android. Usually it is used with 'react-native-smart-image-loader'

  • pageTop, floatSectionHeaderWidth, renderFloatSectionHeader, listSectionProps are used for android to support ios-like sticky header

Method

  • beginRefresh(bounceDisabled): force begin pull down refresh, if bounceDisabled is true, the bounce animation will be disabled
  • endRefresh(bounceDisabled): end pull down refresh, if bounceDisabled is true, the bounce animation will be disabled
