              //here is the origin props of ListView

onTopReachedThreshold threshold to trigger refresh number 10 Android no
renderHeaderRefresh render the custom component of refresh header, and the gestureStatus and offset will be passed, see example for detail func default function all no
onHeaderRefreshing when release to refresh, this fun will be called, see example for detail func default function all no
pullFriction when scroll component is not full of children, pull to refresh is controlled by gesture, and this prop controls how fast to pull down, range: 0 ~ 1 number 0.6 Android no
enableFooterInfinite whether to enable footer load-more bool true all no
setFooterHeight if footer load-more is set, this prop mark the footer height, if footer load-more is set, this prop should be set number 60 Android no

onFooterInfiniting when release to load-more, this fun will be called, see example for detail func default function all no

onHeaderRefreshing and onFooterInfiniting

this props should be passed a function, and gestureStatus and offset will be the params, something like that

onHeaderRefreshing = {(gestureStatus, offset) => <HeaderRefresh gestureStatus={gestureStatus} offset={offset/>}

onFooterInfiniting = {(gestureStatus, offset) => <FooterInfinite gestureStatus={gestureStatus} offset={offset/>}

gestureStatus

  • 0: gesture none
  • 1: pull-up to load-more
  • 2: pull-down to refresh
  • 3: release to refresh or load-more
  • 4: on header refreshing
  • 5: on footer loading-more

offset

  • when pull-down to refresh or pull-up to load-more, this offset params represent the pull distance

static methods

Important: when header refresh done, or footer load-more done, should call this static method

  • headerRefreshDone PTRControl.headerRefreshDone()

    after onHeaderRefreshing, when refresh done, and the data load complete, call this method to stop refresh

  • footerInfiniteDone PTRControl.footerInfiniteDone()

    after onFooterInfiniting, when load-more done, and the data load complete, call this method to stop load-more
