content://com.android.contacts/data/emails 联系人Email
Uri

读取联系人信息
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
null,
null, null, null);
while
(cursor.moveToNext()) {
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+" = "+ contactId,
null,
null);
while
(phones.moveToNext()) {
String phoneNumber = phones.getString(phones.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.i("RongActivity",
"phoneNumber="+phoneNumber);
}
phones.close();

Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = " + contactId,
null,
null);
while
(emails.moveToNext()) {
// This would allow you get several email addresses
String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
Log.i("RongActivity",
"emailAddress="+ emailAddress);
}
emails.close();
}
cursor.close();
