Method Detail

getName

public java.lang.String getName()

Specified by:

getName in class ViewManager<ReactViewGroup,ReactShadowNode>

Returns:

the name of this view manager. This will be the name used to reference this view manager from JavaScript in createReactNativeComponentClass.

createViewInstance

public ReactViewGroup createViewInstance(ThemedReactContext context)

Description copied from class: ViewManager

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

Specified by:

createViewInstance in class ViewManager<ReactViewGroup,ReactShadowNode>

getNativeProps

public java.util.Map<java.lang.String,java.lang.String> getNativeProps()

Overrides:

getNativeProps in class ViewManager<ReactViewGroup,ReactShadowNode>

updateView

public void updateView(ReactViewGroup view,
              CatalystStylesDiffMap props)

Description copied from class: ViewManager

Subclass should use this method to populate native view with updated style properties. In case when a certain property is present in map but the value is null, this property should be reset to the default value TODO(krzysztof) This method should be replaced by updateProperties and removed completely after all view managers adapt @ReactProp

Overrides:

updateView in class ViewGroupManager<ReactViewGroup>

getCommandsMap

public java.util.Map<java.lang.String,java.lang.Integer> getCommandsMap()

Description copied from class: ViewManager

Subclasses of ViewManager 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.

Overrides:

getCommandsMap in class ViewManager<ReactViewGroup,ReactShadowNode>

Returns:

map of string to int mapping of the expected commands

receiveCommand

public void receiveCommand(ReactViewGroup root,
                  int commandId,
                  @Nullable
                  ReadableArray args)

Description copied from class: ViewManager

Subclasses may use this method to receive events/commands directly from JS through the UIManager. Good example of such a command would be scrollTo request with coordinates for a ScrollView or goBack request for a WebView instance.

Overrides:

receiveCommand in class ViewManager<ReactViewGroup,ReactShadowNode>

Parameters:

root - View instance that should receive the command

commandId - code of the command

args - optional arguments for the command

addView

public void addView(ReactViewGroup parent,
           android.view.View child,
           int index)

Overrides:

addView in class ViewGroupManager<ReactViewGroup>

getChildCount

public int getChildCount(ReactViewGroup parent)

Overrides:

getChildCount in class ViewGroupManager<ReactViewGroup>

getChildAt

public android.view.View getChildAt(ReactViewGroup parent,
                           int index)

Overrides:

getChildAt in class ViewGroupManager<ReactViewGroup>

removeView

public void removeView(ReactViewGroup parent,
              android.view.View child)

Overrides:

removeView in class ViewGroupManager<ReactViewGroup>
