Stage模型啟動(dòng)FA模型PageAbility

本小節(jié)介紹Stage模型的兩種應(yīng)用組件如何啟動(dòng)FA模型的PageAbility組件。

UIAbility啟動(dòng)PageAbility

UIAbility啟動(dòng)PageAbility和UIAbility啟動(dòng)UIAbility的方式完全相同。

說明： 需注意FA模型中abilityName由bundleName + AbilityName組成，具體見示例。 開發(fā)前請(qǐng)熟悉鴻蒙開發(fā)指導(dǎo)文檔 ：[gitee.com/li-shizhen-skin/harmony-os/blob/master/README.md]

import { common, Want } from '@kit.AbilityKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@kit.BasicServicesKit';

const TAG: string = '[Page_StartFAModel]';
const DOMAIN_NUMBER: number = 0xFF00;

@Entry
@Component
struct Page_StartFAModel {
  private context = getContext(this) as common.UIAbilityContext;

  build() {
    Column() {
      //...
      List({ initialIndex: 0 }) {
        ListItem() {
          Row() {
            //...
          }
          .onClick(() = > {
            let want: Want = {
              bundleName: 'com.samples.famodelabilitydevelop',
              abilityName: 'com.samples.famodelabilitydevelop.MainAbility'
            };
            this.context.startAbility(want).then(() = > {
              hilog.info(DOMAIN_NUMBER, TAG, 'Start Ability successfully.');
            }).catch((error: BusinessError) = > {
              hilog.error(DOMAIN_NUMBER, TAG, `Ability failed: ` + JSON.stringify(error));
            });
          })
        }
        //...
      }
      //...
    }
    //...
  }
}

UIAbility訪問PageAbility（startAbilityForResult）

startAbilityForResult和startAbility的區(qū)別是當(dāng)PageAbility銷毀的時(shí)候會(huì)返回執(zhí)行結(jié)果。

UIAbility通過startAbilityForResult啟動(dòng)PageABility和UIAbility通過startAbilityForResult啟動(dòng)UIAbility的代碼一樣，沒有任何區(qū)別。

import { common, Want } from '@kit.AbilityKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { promptAction } from '@kit.ArkUI';

const TAG: string = '[Page_StartFAModel]';
const DOMAIN_NUMBER: number = 0xFF00;

@Entry
@Component
struct Page_StartFAModel {
  private context = getContext(this) as common.UIAbilityContext;

  build() {
    Column() {
      //...
      List({ initialIndex: 0 }) {
        ListItem() {
          Row() {
            //...
          }
          .onClick(() = > {
            let want: Want = {
              bundleName: 'com.samples.famodelabilitydevelop',
              abilityName: 'com.samples.famodelabilitydevelop.MainAbility',
            };
            this.context.startAbilityForResult(want).then((result) = > {
              hilog.info(DOMAIN_NUMBER, TAG, 'Ability verify result: ' + JSON.stringify(result));
              if (result !== null) {
                promptAction.showToast({
                  message: JSON.stringify(result)
                });
              }
            }).catch((error: BusinessError) = > {
              hilog.error(DOMAIN_NUMBER, TAG, `Ability failed: ` + JSON.stringify(error));
            });
          })
        }
        //...
      }
      //...
    }
    //...
  }
}

ExtensionAbility啟動(dòng)PageAbility

下面以ServiceExtensionAbility為例來說明ExtensionAbility啟動(dòng)PageAbility。ServiceExtensionAbility啟動(dòng)PageAbility和ServiceExtensionAbility啟動(dòng)UIAbility的方式完全相同。

import { Want, ServiceExtensionAbility } from '@kit.AbilityKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { rpc } from '@kit.IPCKit';
import ServiceExtImpl from '../IdlServiceExt/idl_service_ext_impl';

const TAG: string = '[ServiceExtAbility]';
const DOMAIN_NUMBER: number = 0xFF00;

export default class ServiceExtAbility extends ServiceExtensionAbility {
  serviceExtImpl: ServiceExtImpl = new ServiceExtImpl('ExtImpl');

  onCreate(want: Want): void {
    let serviceExtensionContext = this.context;
    hilog.info(DOMAIN_NUMBER, TAG, `onCreate, want: ${want.abilityName}`);
  };

  onRequest(want: Want, startId: number): void {
    hilog.info(DOMAIN_NUMBER, TAG, `onRequest, want: ${want.abilityName}`);
    if (want.parameters?.key === 'ConnectFaPageAbility') {
      let wantFA: Want = {
        bundleName: 'com.samples.famodelabilitydevelop',
        abilityName: 'com.samples.famodelabilitydevelop.MainAbility',
      };
      this.context.startAbility(wantFA).then(() = > {
        hilog.info(DOMAIN_NUMBER, TAG, 'Start Ability successfully.');
      }).catch((error: BusinessError) = > {
        hilog.info(DOMAIN_NUMBER, TAG, `Ability failed: ${JSON.stringify(error)}`);
      });
    }
  };

  onConnect(want: Want): rpc.RemoteObject {
    hilog.info(DOMAIN_NUMBER, TAG, `onConnect, want: ${want.abilityName}`);
    // 返回ServiceExtImpl對(duì)象，客戶端獲取后便可以與ServiceExtensionAbility進(jìn)行通信
    return this.serviceExtImpl as rpc.RemoteObject;
  };

  onDisconnect(want: Want): void {
    hilog.info(DOMAIN_NUMBER, TAG, `onDisconnect, want: ${want.abilityName}`);
  };

  onDestroy(): void {
    hilog.info(DOMAIN_NUMBER, TAG, 'onDestroy');
  };
}
