Method Detail

• getName

   String getName()

• createViewInstance

   ReactScrollView createViewInstance(ThemedReactContext context)

  Subclasses should return a new View instance of the proper type.

• setScrollEnabled

   void setScrollEnabled(ReactScrollView view, boolean value)

• setShowsVerticalScrollIndicator

   void setShowsVerticalScrollIndicator(ReactScrollView view, boolean value)

• setDecelerationRate

   void setDecelerationRate(ReactScrollView view, float decelerationRate)

• setDisableIntervalMomentum

   void setDisableIntervalMomentum(ReactScrollView view, boolean disbaleIntervalMomentum)

• setSnapToInterval

   void setSnapToInterval(ReactScrollView view, float snapToInterval)

• setSnapToOffsets

   void setSnapToOffsets(ReactScrollView view, @Nullable() ReadableArray snapToOffsets)

• setSnapToAlignment

   void setSnapToAlignment(ReactScrollView view, String alignment)

• setSnapToStart

   void setSnapToStart(ReactScrollView view, boolean snapToStart)

• setSnapToEnd

   void setSnapToEnd(ReactScrollView view, boolean snapToEnd)

• setRemoveClippedSubviews

   void setRemoveClippedSubviews(ReactScrollView view, boolean removeClippedSubviews)

• setSendMomentumEvents

   void setSendMomentumEvents(ReactScrollView view, boolean sendMomentumEvents)

  Computing momentum events is potentially expensive since we post a runnable on the UI thread tosee when it is done. We only do that if {@param sendMomentumEvents} is set to true. This ishandled automatically in js by checking if there is a listener on the momentum events.

• setScrollPerfTag

   void setScrollPerfTag(ReactScrollView view, @Nullable() String scrollPerfTag)

  Tag used for logging scroll performance on this scroll view. Will force momentum events to beturned on (see setSendMomentumEvents).

• setPagingEnabled

   void setPagingEnabled(ReactScrollView view, boolean pagingEnabled)

• setBottomFillColor

   void setBottomFillColor(ReactScrollView view, int color)

  When set, fills the rest of the scrollview with a color to avoid setting a background andcreating unnecessary overdraw.

• setOverScrollMode

   void setOverScrollMode(ReactScrollView view, String value)

  Controls overScroll behaviour

• setNestedScrollEnabled

   void setNestedScrollEnabled(ReactScrollView view, boolean value)

• getCommandsMap

  @Nullable() Map<String, Integer> getCommandsMap()

  Subclasses of ViewManager that expect to receive commands through should override this method returning the mapbetween names of the commands and IDs that are then used in receiveCommand methodwhenever the command is dispatched for this particular ViewManager.

• receiveCommand

   void receiveCommand(ReactScrollView scrollView, int commandId, @Nullable() ReadableArray args)

  Subclasses may use this method to receive events/commands directly from JS through the . Good example of such a command would be {@code scrollTo} request with coordinatesfor a ScrollView instance.

  This method is deprecated use receiveCommand instead.

  Parameters:

  commandId - code of the command

  args - optional arguments for the command

• receiveCommand

   void receiveCommand(ReactScrollView scrollView, String commandId, @Nullable() ReadableArray args)

  Subclasses may use this method to receive events/commands directly from JS through the . Good example of such a command would be {@code scrollTo} request with coordinatesfor a ReactScrollView instance.

  Parameters:

  commandId - code of the command

  args - optional arguments for the command

• flashScrollIndicators

   void flashScrollIndicators(ReactScrollView scrollView)

• scrollTo

   void scrollTo(ReactScrollView scrollView, ReactScrollViewCommandHelper.ScrollToCommandData data)

• setBorderRadius

   void setBorderRadius(ReactScrollView view, int index, float borderRadius)

• setBorderStyle

   void setBorderStyle(ReactScrollView view, @Nullable() String borderStyle)

• setBorderWidth

   void setBorderWidth(ReactScrollView view, int index, float width)

• setBorderColor

   void setBorderColor(ReactScrollView view, int index, Integer color)

• setOverflow

   void setOverflow(ReactScrollView view, @Nullable() String overflow)

• scrollToEnd

   void scrollToEnd(ReactScrollView scrollView, ReactScrollViewCommandHelper.ScrollToEndCommandData data)

• setPersistentScrollbar

   void setPersistentScrollbar(ReactScrollView view, boolean value)

• setFadingEdgeLength

   void setFadingEdgeLength(ReactScrollView view, int value)

• setContentOffset

   void setContentOffset(ReactScrollView view, ReadableMap value)

• updateState

   Object updateState(ReactScrollView view, ReactStylesDiffMap props, @Nullable() StateWrapper stateWrapper)

  Subclasses can implement this method to receive state updates shared between all instances ofthis component type.

• getExportedCustomDirectEventTypeConstants

  @Nullable() Map<String, Object> getExportedCustomDirectEventTypeConstants()

  Returns a map of config data passed to JS that defines eligible events that can be placed onnative views. This should return non-bubbling directly-dispatched event types.

  Returned map should be of the form:

  {
    "onTwirl": {
      "registrationName": "onTwirl"
    }
  }
  

• createExportedCustomDirectEventTypeConstants

   static Map<String, Object> createExportedCustomDirectEventTypeConstants()

• setPointerEvents

   void setPointerEvents(ReactScrollView view, @Nullable() String pointerEventsStr)
