android开发怎样获取通讯录联系人信息

给你个方法~

//定义一个获取联系人的方法,返回的是List的数据
public List getContacts()
{
List Contacts = new ArrayList();
//①查询raw_contacts表获得联系人的id
ContentResolver resolver = getContentResolver();
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
//查询联系人数据
Cursor cursor = resolver.query(uri, null, null, null, null);
while(cursor.moveToNext())
{
Contact contact = new Contact();
//获取联系人姓名,手机号码
contact.setId(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)));
contact.setName(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
contact.setPhone(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
Contacts.add(contact);
}
cursor.close();
return Contacts;
}

还有一个实体类Contact ：
private String id;
private String name;
private String phone;
