一、跳转应用详情页

鸿蒙跳转应用详情页功能，使用场景可以是引导用户进入应用详情页授予应用权限。

TypeScript 复制代码

  gotoAppDetail(context:common.UIAbilityContext){

    let bundleName = bundleManager.getBundleInfoForSelfSync(bundleManager.BundleFlag.GET_BUNDLE_INFO_DEFAULT).name

    let wantInfo: Want = {
      bundleName: 'com.huawei.hmos.settings',
      abilityName: 'com.huawei.hmos.settings.MainAbility',
      uri: 'application_info_entry',
      parameters: {
        pushParams: bundleName // 打开指定应用的详情页面
      }
    }
    context.startAbility(wantInfo)
  }

二、如何获取 UIAbilityContext

1.在 UIAbility 中获取

TypeScript 复制代码

import UIAbility from '@ohos.app.ability.UIAbility';
import AbilityConstant from '@ohos.app.ability.AbilityConstant';
import Want from '@ohos.app.ability.Want';

export default class EntryAbility extends UIAbility {
  onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
    // 获取UIAbility实例的上下文
    let context = this.context;
  }
}

2.在页面中获取

TypeScript 复制代码

import common from '@ohos.app.ability.common';
import Want from '@ohos.app.ability.Want';

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

  // 页面展示
  build() {
  }
}
