Method Detail

addRootView

public <T extends android.view.View> int addRootView(T rootView,
                                                     WritableMap initialProps,
                                                     java.lang.String initialUITemplate)

Description copied from interface: UIManager

Registers a new root view.

Specified by:

addRootView in interface UIManager

onRequestEventBeat

public void onRequestEventBeat()

Method called when an event has been dispatched on the C++ side.

removeRootView

public void removeRootView(int reactRootTag)

Description copied from interface: UIManager

Unregisters a new root view.

Specified by:

removeRootView in interface UIManager

initialize

public void initialize()

Description copied from interface: JSIModule

This is called at the end of CatalystApplicationFragment#createCatalystInstance() after the CatalystInstance has been created, in order to initialize NativeModules that require the CatalystInstance or JS modules.

Specified by:

initialize in interface JSIModule

onCatalystInstanceDestroy

public void onCatalystInstanceDestroy()

Description copied from interface: JSIModule

Called before {CatalystInstance#onHostDestroy}

Specified by:

onCatalystInstanceDestroy in interface JSIModule

synchronouslyUpdateViewOnUIThread

public void synchronouslyUpdateViewOnUIThread(int reactTag,
                                              ReadableMap props)

Description copied from interface: UIManager

Used by native animated module to bypass the process of updating the values through the shadow view hierarchy. This method will directly update native views, which means that updates for layout-related propertied won't be handled properly. Make sure you know what you're doing before calling this method :)

Specified by:

synchronouslyUpdateViewOnUIThread in interface UIManager

props - ReadableMap props that should be immediately updated in view

setBinding

public void setBinding(Binding binding)

updateRootLayoutSpecs

public void updateRootLayoutSpecs(int rootTag,
                                  int widthMeasureSpec,
                                  int heightMeasureSpec)

Updates the layout metrics of the root view based on the Measure specs received by parameters.

Specified by:

updateRootLayoutSpecs in interface UIManager

receiveEvent

public void receiveEvent(int reactTag,
                         java.lang.String eventName,
                         WritableMap params)

onHostResume

public void onHostResume()

Description copied from interface: LifecycleEventListener

Called either when the host activity receives a resume event (e.g. Activity#onResume or if the native module that implements this is initialized while the host activity is already resumed. Always called for the most current activity.

Specified by:

onHostResume in interface LifecycleEventListener

onHostPause

public void onHostPause()

Description copied from interface: LifecycleEventListener

Called when host activity receives pause event (e.g. Activity#onPause. Always called for the most current activity.

Specified by:

onHostPause in interface LifecycleEventListener

onHostDestroy

public void onHostDestroy()

Description copied from interface: LifecycleEventListener

Called when host activity receives destroy event (e.g. Activity#onDestroy. Only called for the last React activity to be destroyed.

Specified by:

onHostDestroy in interface LifecycleEventListener

                            int commandId,
                            ReadableArray commandArgs)

Description copied from interface: UIManager

Specified by:

dispatchCommand in interface UIManager

Parameters:

reactTag - int that identifies the view that will receive this command

commandId - int command id

commandArgs - ReadableArray parameters associated with the command
