HarmonyOS 应用开发之FA模型启动Stage模型UIAbility

本文介绍FA模型的三种应用组件如何启动Stage模型的UIAbility组件。

PageAbility启动UIAbility

在PageAbility中启动UIAbility和在PageAbility中启动PageAbility的方式完全相同。

复制代码

import featureAbility from '@ohos.ability.featureAbility';
import { BusinessError } from '@ohos.base';
import Want from '@ohos.app.ability.Want';
import Logger from '../../utils/Logger';

const TAG: string = 'PageInterflowFaAndStage';

let want: Want = {
  bundleName: 'ohos.samples.etsclock',
  abilityName: 'MainAbility'
};
featureAbility.startAbility({ want }).then((code) => {
  Logger.info(TAG, 'Ability verify code: ' + JSON.stringify(code));
}).catch((error: BusinessError) => {
  Logger.error(TAG, 'Ability failed: ' + JSON.stringify(error));
});

PageAbility访问UIAbility（startAbilityForResult）

startAbilityForResult和startAbility的区别是当UIAbility销毁的时候会返回执行结果。

在PageAbility中通过startAbilityForResult启动UIAbility和在PageAbility中通过startAbilityForResult启动PageAbility的方式完全相同。

复制代码

import featureAbility from '@ohos.ability.featureAbility';
import { BusinessError } from '@ohos.base';
import Want from '@ohos.app.ability.Want';
import Logger from '../../utils/Logger';

const TAG: string = 'PageInterflowFaAndStage';

let want: Want = {
  bundleName: 'ohos.samples.etsclock',
  abilityName: 'MainAbility'
};
featureAbility.startAbilityForResult({ want }).then((result) => {
  Logger.info(TAG, 'Ability verify result: ' + JSON.stringify(result));
}).catch((error: BusinessError) => {
  Logger.error(TAG, 'Ability failed: ' + JSON.stringify(error));
});

ServiceAbility/DataAbility启动UIAbility

在ServiceAbility/DataAbility中启动UIAbility和在ServiceAbility/DataAbility中启动PageAbility的方式完全相同。

复制代码

import particleAbility from '@ohos.ability.particleAbility';
import { BusinessError } from '@ohos.base';
import Want from '@ohos.app.ability.Want';
import hilog from '@ohos.hilog';

const TAG: string = '[Sample_FAModelAbilityDevelop]';

let want: Want = {
  bundleName: 'ohos.samples.etsclock',
  abilityName: 'MainAbility'
};
particleAbility.startAbility({ want }).then(() => {
  hilog.info(TAG, 'StartUIAbility Start Ability successfully.');
}).catch((error: BusinessError) => {
  hilog.error(TAG, 'StartUIAbility Ability failed: ' + JSON.stringify(error));
});
hilog.info(TAG, 'StartUIAbility ServiceAbility onStart');
