LifecycleForm接口切换
| FA模型接口 | Stage模型接口对应d.ts文件 | Stage模型对应接口 |
|---|---|---|
| onCreate?(want: Want): formBindingData.FormBindingData; | @ohos.app.form.FormExtensionAbility.d.ts | onAddForm(want: Want): formBindingData.FormBindingData; |
| onCastToNormal?(formId: string): void; | @ohos.app.form.FormExtensionAbility.d.ts | onCastToNormalForm(formId: string): void; |
| onUpdate?(formId: string): void; | @ohos.app.form.FormExtensionAbility.d.ts | onUpdateForm(formId: string): void; |
| onVisibilityChange?(newStatus: Record<string, number>): void; | @ohos.app.form.FormExtensionAbility.d.ts | onChangeFormVisibility(newStatus: Record<string, number>): void; |
| onEvent?(formId: string, message: string): void; | @ohos.app.form.FormExtensionAbility.d.ts | onFormEvent(formId: string, message: string): void; |
| onDestroy?(formId: string): void; | @ohos.app.form.FormExtensionAbility.d.ts | onRemoveForm(formId: string): void; |
| onAcquireFormState?(want: Want): formInfo.FormState; | @ohos.app.form.FormExtensionAbility.d.ts | onAcquireFormState?(want: Want): formInfo.FormState; |
| onShareForm?(formId: string): Record<string, Object>; | @ohos.app.form.FormExtensionAbility.d.ts | onShareForm?(formId: string): Record<string, Object>; |
LifecycleApp接口切换
| FA模型接口 | Stage模型接口对应d.ts文件 | Stage模型对应接口 |
|---|---|---|
| onShow?(): void; | @ohos.window.d.ts | on(eventType: ‘windowStageEvent’, callback: Callback<WindowStageEventType>): void; 监听FOREGROUND切到前台状态 |
| onHide?(): void; | @ohos.window.d.ts | on(eventType: ‘windowStageEvent’, callback: Callback<WindowStageEventType>): void; 监听 BACKGROUND 切到后台状态 |
| onDestroy?(): void; | @ohos.app.ability.UIAbility.d.ts | onDestroy(): void; |
| onCreate?(): void; | @ohos.app.ability.UIAbility.d.ts | onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void; |
| onWindowDisplayModeChanged?(isShownInMultiWindow: boolean, newConfig: resourceManager.Configuration): void; | Stage模型无对应接口 | 暂时未提供对应接口 |
| onStartContinuation?(): boolean; | Stage模型无对应接口 | Stage模型上，应用无需感知迁移是否成功（由应用发起迁移请求时感知），onStartContinuation废弃 |
| onSaveData?(data: Object): boolean; | @ohos.app.ability.UIAbility.d.ts | onContinue(wantParam: Record<string, Object>): AbilityConstant.OnContinueResult; |
| onCompleteContinuation?(result: number): void; | application\ContinueCallback.d.ts | onContinueDone(result: number): void; |
| onRestoreData?(data: Object): void; | @ohos.app.ability.UIAbility.d.ts | onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void; onNewWant(want: Want, launchParam: AbilityConstant.LaunchParam): void; 多实例模式Ability迁移目标端在onCreate回调中完成数据恢复，单实例模式应用迁移目标端在onCreate回调中完成数据恢复，回调中通过判断launchParam.launchReason可获取迁移启动的场景，从而可以从Want中获取迁移前保存的数据 |
| onRemoteTerminated?(): void; | application\ContinueCallback.d.ts | onContinueDone(result: number): void; |
| onSaveAbilityState?(outState: PacMap): void; | @ohos.app.ability.UIAbility.d.ts | onSaveState(reason: AbilityConstant.StateType, wantParam : Record<string, Object>): AbilityConstant.OnSaveResult; |
| onRestoreAbilityState?(inState: PacMap): void; | @ohos.app.ability.UIAbility.d.ts | onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void; 应用重启后会触发Ability的onCreate方法，通过判断launchParam.launchReason可获取自恢复的场景，从而可以从Want中获取重启前保存的数据 |
| onInactive?(): void; | @ohos.app.ability.UIAbility.d.ts | onBackground(): void; |
| onActive?(): void; | @ohos.app.ability.UIAbility.d.ts | onForeground(): void; |
| onNewWant?(want: Want): void; | @ohos.app.ability.UIAbility.d.ts | onNewWant(want: Want, launchParam: AbilityConstant.LaunchParam): void; |
| onMemoryLevel?(level: number): void | @ohos.app.ability.UIAbility.d.ts | onMemoryLevel(level: AbilityConstant.MemoryLevel): void; |
