#鸿蒙通关秘籍#如何在鸿蒙应用中启动应用内的UIAbility？

在鸿蒙应用中如需启动应用内的UIAbility，可通过如下步骤：

1. 在启动UIAbility的代码中使用 startAbility 方法，并传入 Want 对象作为参数。 Want 对象中需指定 bundleName 和 abilityName。

bash import { common, Want } from '@kit.AbilityKit'; const context = getContext(this) as common.UIAbilityContext; let wantInfo: Want = { deviceId: '', bundleName: 'com.samples.stagemodelabilitydevelop', moduleName: 'entry', abilityName: 'FuncAbilityA', parameters: { info: '来自EntryAbility Page_UIAbilityComponentsInteractive页面' }, }; context.startAbility(wantInfo);

2. 在被启动的UIAbility中，通过 onCreate 或 onNewWant 方法接收参数。

bash import { AbilityConstant, UIAbility, Want } from '@kit.AbilityKit'; export default class FuncAbilityA extends UIAbility { onCreate(want: Want, launchParam: AbilityConstant.LaunchParam) { let info = want.parameters?.info; } }

3. 业务完成后，调用 terminateSelf 方法关闭当前UIAbility。

bash import { common } from '@kit.AbilityKit'; const context: common.UIAbilityContext = getContext(this) as common.UIAbilityContext; context.terminateSelf();
