接口 AbilitySlice.FormCallback

封闭类:

AbilitySlice

public static interface AbilitySlice.FormCallback

Provides callbacks that will be invoked when a Form instance is obtained or when the Form provider is uninstalled.

This interface must be implemented to listen for the Form acquisition result and uninstallation event of the form provider if your application needs to call AbilitySlice.acquireForm(ohos.aafwk.content.Intent,ohos.aafwk.ability.AbilitySlice.FormCallback) to obtain a Form instance.
