public class ReactTextViewManager
extends BaseViewManager<ReactTextView,ReactTextShadowNode>

Manages instances of spannable TextView. This is a "shadowing" view manager, which means that the NativeViewHierarchyManager will not manage children of native TextView instances returned by this manager. Instead we use

Method Detail

getName

public java.lang.String getName()

Specified by:

getName in class ViewManager<ReactTextView,ReactTextShadowNode>

Returns:

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

createViewInstance

public ReactTextView 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<ReactTextView,ReactTextShadowNode>

setNumberOfLines

public void setNumberOfLines(ReactTextView view,
                    int numberOfLines)

setTextAlign

public void setTextAlign(ReactTextView view,
                @Nullable
                java.lang.String textAlign)

setLineHeight

public void setLineHeight(ReactTextView view,
                 float lineHeight)

updateExtraData

public void updateExtraData(ReactTextView view,
                   java.lang.Object extraData)

Description copied from class: ViewManager

Subclasses can implement this method to receive an optional extra data enqueued from the corresponding instance of ReactShadowNode in ReactShadowNode.onCollectExtraUpdates(com.facebook.react.uimanager.UIViewOperationQueue). Since css layout step and ui updates can be executed in separate thread apart of setting x/y/width/height this is the recommended and thread-safe way of passing extra data from css node to the native view counterpart. TODO(7247021): Replace updateExtraData with generic update props mechanism after D2086999

Specified by:

updateExtraData in class ViewManager<ReactTextView,ReactTextShadowNode>

createShadowNodeInstance

public ReactTextShadowNode createShadowNodeInstance()

Description copied from class: ViewManager

This method should return a subclass of ReactShadowNode which will be then used for measuring position and size of the view. In mose of the cases this should just return an instance of ReactShadowNode

Specified by:

createShadowNodeInstance in class ViewManager<ReactTextView,ReactTextShadowNode>

getShadowNodeClass

public java.lang.Class<ReactTextShadowNode> getShadowNodeClass()

Description copied from class: ViewManager

This method should return Class instance that represent type of shadow node that this manager will return from ViewManager.createShadowNodeInstance(). This method will be used in the bridge initialization phase to collect properties exposed using ReactProp (or ReactPropGroup) annotation from the ReactShadowNode subclass specific for native view this manager provides.

Specified by:

getShadowNodeClass in class ViewManager<ReactTextView,ReactTextShadowNode>

Returns:

Class object that represents type of shadow node used by this view manager.
