将Android的contacts2.db导出成vcard联系人的方法

从Android的contacts2.db中导出vcard联系人方法，只简单说明下步骤

1：拿到contacts2.db文件

两种方法

(1):通过手机的RE管理工具将目录data/data/com.android.providers.contacts/databases/contacts2.db文件拷贝出来

(2):通过Recovery备份的文件data.img用unyaff程序解压缩后，可找到对应的data/data/com.android.providers.contacts/databases/contacts2.db文件，该方法适用于进不了系统的情况

2：使用java sqlite驱动包

下载地址：http://www.ch-werner.de/javasqlite/

3：使用android的vcard jar包

下载地址：http://code.google.com/p/android-vcard/

4：编写java代码进行数据的导出

(1)：先读取数据库中contacts表，生成用户名和ID的对象

(2)：遍历用户列表，根据用户ID读取raw_contacts和data表获取号码、地址等信息(两个表需要关联)

判断表中mimetype_id类型，一般mimetype_id值的定义：3: 地址 data1 5: 手机号码 data1 8: 名称 data1全名 data2名 data3姓 9:其他信息 data1地址 data4职位

(3)：遍历用户列表，将用户信息导出到vcard文件

附上代码：

    public void setAddress(String address) {

    }

    public String getDuty() {
        return duty;
    }

    public void setDuty(String duty) {
        this.duty = duty;
    }

    public String toString() {
        String result = "";
        result += "ID:(" + userid;
        result += ") 姓名:(" + name;

        result += ")";
        return result;
    }
}
