public class ReactScrollViewManager extends ViewGroupManager<ReactScrollView> implements ReactScrollViewCommandHelper.ScrollCommandHandler<ReactScrollView>
ReactScrollView components.
Note that ReactScrollView and ReactHorizontalScrollView are exposed to JS
as a single ScrollView component, configured via the horizontal boolean property.

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

Subclasses of
ViewManager that expect to receive commands through

map between names of the commands and IDs that are then used in ViewManager.receiveCommand(T, int, com.facebook.react.bridge.ReadableArray) method
whenever the command is dispatched for this particular ViewManager. |

Returns a map of config data passed to JS that defines eligible events that can be placed on
native views.

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

java.lang.String value)
Controls overScroll behaviour

setScrollPerfTag(ReactScrollView view,
java.lang.String scrollPerfTag)
Tag used for logging scroll performance on this scroll view.
|
void |
setSendMomentumEvents(ReactScrollView view,
boolean sendMomentumEvents)
Computing momentum events is potentially expensive since we post a runnable on the UI thread
to see when it is done.

ViewManagerViewManager that expect to receive commands through
UIManagerModule.dispatchViewManagerCommand(int, int, com.facebook.react.bridge.ReadableArray) should override this method returning the
map between names of the commands and IDs that are then used in ViewManager.receiveCommand(T, int, com.facebook.react.bridge.ReadableArray) method
whenever the command is dispatched for this particular ViewManager.
As an example we may consider ReactWebViewManager that expose the following commands:
goBack, goForward, reload. In this case the map returned from ViewManager.getCommandsMap() from
ReactWebViewManager will look as follows:
{
"goBack": 1,
"goForward": 2,
"reload": 3,
}
Now assuming that "reload" command is dispatched through UIManagerModule we trigger
ReactWebViewManager#receiveCommand passing "3" as commandId argument.getCommandsMap in class ViewManager<ReactScrollView,LayoutShadowNode>public void receiveCommand(ReactScrollView scrollView, int commandId, @Nullable ReadableArray args)
ViewManagerUIManager. Good example of such a command would be scrollTo request with
coordinates for a ScrollView or goBack request for a WebView instance.receiveCommand in class ViewManager<ReactScrollView,LayoutShadowNode>scrollView - View instance that should receive the commandcommandId - code of the commandargs - optional arguments for the commandpublic void flashScrollIndicators(ReactScrollView scrollView)
