如何拉起短信界面并指定联系人

开发者可以通过显式指定bundleName为com.ohos.mms、abilityName为com.ohos.mms.MainAbility来拉起联系人应用，其中contactsName为用户名，telephone为电话号码。具体可参考如下代码。

import { common, Want } from '@kit.AbilityKit'; 
import { BusinessError } from '@kit.BasicServicesKit'; 
interface ModelContactInfo { 
  contactsName: string; 
  telephone: string; 
} 
function startMMSAbility(context: common.UIAbilityContext): void { 
  let contactInfo: Array<ModelContactInfo> = [{ 
    contactsName: 'ZhangSan', 
    telephone: '16888888888' 
  }]; 
  let want: Want = { 
    bundleName: 'com.ohos.mms', 
    abilityName: 'com.ohos.mms.MainAbility', 
    parameters: { 
      contactObjects: JSON.stringify(contactInfo), 
      pageFlag: 'conversation' 
    } 
  }; 
  context.startAbility(want).then(() => { 
    console.info('Start MMSAbility successfully.'); 
  }).catch((err: BusinessError) => { 
    console.error(`Failed to startAbility. Code: ${err.code}, message: ${err.message}`); 
  }); 
} 
 
@Entry 
@Component 
struct StartMMSAbilityView { 
  @State message: string = '拉起短信界面并指定联系人'; 
  build() { 
    Row() { 
      Column() { 
        Button(this.message) 
          .fontSize(24) 
          .fontWeight(FontWeight.Bold) 
          .onClick(() => { 
            const context: common.UIAbilityContext = getContext(this) as common.UIAbilityContext; 
            startMMSAbility(context); 
          }) 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
}
