代码实现

权限申请

在config.json文件添加ohos.permission.READ_CONTACTS和ohos.permission.WRITE_CONTACTS，并且在mainAbility文件动态申请权限，代码如下

"reqPermissions": [
      {"name": "ohos.permission.READ_CONTACTS"},
      {
        "name": "ohos.permission.WRITE_CONTACTS"

代码实现

在MainAbilitySlice代码onstart方法中实现添加联系人，代码如下

package com.example.myapplication.slice;

import com.example.myapplication.ResourceTable;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.sysappcomponents.contact.ContactsHelper;
import ohos.sysappcomponents.contact.entity.Contact;
import ohos.sysappcomponents.contact.entity.Name;
import ohos.sysappcomponents.contact.entity.PhoneNumber;

public class MainAbilitySlice extends AbilitySlice {
    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_ability_main);
        //初始化 ContactsHelper 对象
        ContactsHelper contactsHelper = new ContactsHelper(getContext());
        //todo 初始化 Contact
        Contact contact = new Contact();
        //todo 初始化 Name
        Name name = new Name();
        //todo 设置姓名
        name.setFullName("小明");
        //todo 初始化 PhoneNumber
        PhoneNumber phoneNumber=new PhoneNumber(getContext(),"13888888888",0);
        //todo 添加电话对象
        contact.addPhoneNumber(phoneNumber);
        //todo 添加姓名对象
        contact.setName(name);
        //todo 添加contact对象
