具体方法如下：
①.、定义封装一条记录的实体类
import java.util.Scanner;
class Contact {
String cellPhone;
String name;
}
public class Main {
private static void menu () {
System.out.println("************** 菜单 ******"
+ "************");
System.out.println(" 1.显示全部通讯录");
System.out.println(" 0.退出");
public static void main(String[] args) {
Scanner scn = new Scanner(System.in);
int size = 0;
String cmd = "";
do {
menu();
cmd = scn.nextLine();
if (cmd.equals("1")) {
if (size == 0)
System.out.println("系统当前无记录！");
else
for (int i = 0; i size; i++) {
System.out.println(contacts[i].name + ":"
+ contacts[i].cellPhone);
System.out.print("请输入手机号：");
String cellphone = scn.nextLine();
System.out.print("请输入姓名：");
String name = scn.nextLine();
Contact contact = new Contact();
contact.cellPhone = cellphone;
contact.name = name;
if (size contacts.length) {
contacts[size++] = contact;
System.out.println("添加成功！");
} else {
System.out.println("你最多只能添加" +
contacts.length + "条记录");
System.out.print("请输入要删除的手机号：");
int index = -1;
for (int i = 0; i size i contacts.length;
i++) {
if (contacts[i].cellPhone.equals(cellphone)) {
index = i;
break;
if (index == -1) {
System.out.println("该记录不存在！");
for (int i = index; i size; i++) {
contacts[index] = contacts[index + 1];
contacts[size - 1] = null;
size--;
System.out.println("删除成功！");
System.out.print("请输入要修改的手机号：");
contacts[index].name = name;
} while (!cmd.equals("0"));
System.out.println("退出成功！");
scn.close();
System.exit(0);
翻了半天找到以前写的,只写了部分,你可以参考一下

你就怎么那么小气呢！给个几十分也不亏你！
算了,刚写的就便宜你了！
public class Shopping {
System.out.println("\t\t\t\t1.添加联系人信息\n");
System.out.println("请选择,输入数字或按"n"返回上一级菜单：");
num = scanner.nextLine();
if (num.equals("n"))
isR = true;
else if(num.equals("1")){
System.out.println("添加联系人信息");
System.out.println("输入联系人的姓名: ");
String birthDayNum = num;
System.out.println("输入联系人的电话: ");
System.out.print("是否继续添加（y/e）：");
String numJixu = scanner.nextLine();
if (numJixu.equals("y"))
else {
isEnd = true;
System.out.println("查看联系人");
System.out.print("请输入联系人姓名：");
String snum = scanner.nextLine();
int numberNum = Integer.parseInt(snum);
就给你发这么多吧！还有一点点自己琢磨吧！我也没时间整理了！！
getContentResolver().delete()需要填入三个参数,才能删除全部联系人,代码如下：
ContentResolver?cr?=?getContentResolver();
Cursor?cur?=?cr.query(ContactsContract.Contacts.CONTENT_URI,
null,?null,?null,?null);
while?(cur.moveToNext())?{
try{
String?lookupKey?=?cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.LOOKUP_KEY));
Uri?uri?=?Uri.withAppendedPath(ContactsContract.
Contacts.CONTENT_LOOKUP_URI,?lookupKey);
System.out.println("The?uri?is?"?+?uri.toString());
cr.delete(uri,?null,?null);//删除所有的联系人
catch(Exception?e)

System.out.println(e.getStackTrace());
