常用代码:
// 查询通讯录中联系人?
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
// 获取手机号
Cursor phone =
cursor.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +"="+ ContactId, null, null);
// 复杂点:
Cursor phone = cursor.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +"="+ ContactId +" AND "+ ContactsContract.CommonDataKinds.Phone.TYPE +"="+ ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE, null, null);
ContactsContract.CommonDataKinds.Phone.TYPE 表示联系人电话的类型,
主要对应如下:
TYPE_MOBILE : 手机号码
TYPE_HOME : 住宅电话
TYPE_WORK : 公司电话
