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。

import featureAbility from '@ohos.ability.featureAbility';

let parameter = {
    "want": {
        bundleName: "com.ohos.stage",
        abilityName: "com.ohos.stage.EntryAbility"
    }
};
featureAbility.startAbility(parameter).then((code) => {
    console.info('Ability verify code: ' + JSON.stringify(code));
}).catch((error) => {
    console.error("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。

import featureAbility from '@ohos.ability.featureAbility';

let parameter = {
    "want": {
        bundleName: "com.ohos.stage",
        abilityName: "com.ohos.stage.EntryAbility"
    }
};
featureAbility.startAbilityForResult(parameter).then((result) => {
    console.info('Ability verify result: ' + JSON.stringify(result));
}).catch((error) => {
    console.error("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。

import particleAbility from '@ohos.ability.particleAbility';

let parameter = {
    "want": {
        bundleName: "com.ohos.stage",
        abilityName: "com.ohos.stage.EntryAbility"
    }
};
particleAbility.startAbility(parameter).then(() => {
    console.info('Start Ability successfully.');
}).catch((error) => {
    console.error("Ability failed: " + JSON.stringify(error));
});
