com.facebook.react.views.progressbar.ReactProgressBarViewManager

public class ReactProgressBarViewManager
extends ViewManager<android.widget.FrameLayout,ProgressBarShadowNode>

Manages instances of ProgressBar. ProgressBar is wrapped in a FrameLayout because the style of the ProgressBar can only be set in the constructor; whenever the style of a ProgressBar changes, we have to drop the existing ProgressBar (if there is one) and create a new one with the style given.

updateExtraData

public void updateExtraData(android.widget.FrameLayout root,
                   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<android.widget.FrameLayout,ProgressBarShadowNode>
