如何从联系人列表中获取电子邮件地址。下面的代码我得到了号码和名称并显示在列表上。但我想要号码，姓名和电子邮件地址，请查看以下代码
ContentResolver contactResolver = context.getContentResolver();
Cursor c = contactResolver.query(ContactsContract.Contacts.CONTENT_URI, new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.HAS_PHONE_NUMBER }, null, null, null);
Cursor cursor = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
null, null, null);
if(cursor.getCount()>0)
while ( cursor.moveToNext()) {
String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String number = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
// String photoUri = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_THUMBNAIL_URI));
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
// String lookupKey = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
Log.e("TAG", " Name: " + displayName+"==>phone Number==>"+number);
contactNameArrayList.add(displayName);
contactNumberArrayList.add(number);
if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
Cursor pCur = contactResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { contactId }, null);
while (pCur.moveToNext())
{
String phone = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String type = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
String s = (String) ContactsContract.CommonDataKinds.Phone.getTypeLabel(context.getResources(), Integer.parseInt(type), "");
// Log.e("TAG", s + " phone: " + phone);
}
pCur.close();
}
Cursor emailCursor = contactResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
null, null, null);
while (emailCursor.moveToNext())
{
String email = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
int type = emailCursor.getInt(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
String s = (String) ContactsContract.CommonDataKinds.Email.getTypeLabel(context.getResources(), type, "");
Log.e("TAG", s + " email: " + email);
}
emailCursor.close();
} cursor.close();
Log.e(TAG,"contactNameArrayList sIZE==>"+contactNameArrayList.size()+"contactNumberArrayList size==>"+contactNumberArrayList.size()+"contactEmailAddressArrayList size==>"+contactEmailAddressArrayList.size());

public List<String> getEmail(int contactId) {
List<String> emailStr = new ArrayList<String>();
ContentResolver cr = context.getContentResolver();
Cursor emailCur = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{String.valueOf(contactId)}, null);
while (emailCur.moveToNext()) {
String email = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
emailStr.add(email);
System.out.println("Email " + email );
}
emailCur.close();
return emailStr;
}

使用以下代码从一个联系人和电话簿中的所有联系人处获取多个号码和电子邮件。
private void getContactsFromPhoneBook() {
String unique_id = ApplicationConstant.phone_id;
System.out.println("Unique_ID : " + unique_id);
Contact_To_Sync contact_to_sync = new Contact_To_Sync();
List<Contacts> AllContact_toSync = new ArrayList<>();
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
System.out.println("Contacts Count : " + cur.getCount());
if (cur.getCount() > 0) {
Contacts contacts = null;
List<String> Phones;
List<String> Emails;
while (cur.moveToNext()) {
contacts = new Contacts();
Phones = new ArrayList<>();
Emails = new ArrayList<>();
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String timeStamp = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.CONTACT_LAST_UPDATED_TIMESTAMP));
contacts.setContact_id(id);
contacts.setName(name);
System.out.println("name : " + name + ", ID : " + id + " Status : " + timeStamp);
// get the phone number
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
String phone = pCur.getString(
pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
System.out.println("phone" + phone);
Phones.add(phone);
}
pCur.close();
// get email and type
Cursor emailCur = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
while (emailCur.moveToNext()) {
// This would allow you get several email addresses
// if the email addresses were stored in an array
String email = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
String emailType = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
Emails.add(email);
System.out.println("Email " + email + " Email Type : " + emailType);
}
emailCur.close();
contacts.setEmails(Emails);
contacts.setPhones(Phones);
AllContact_toSync.add(contacts);
}
contact_to_sync.setContacts(AllContact_toSync);
contact_to_sync.setPhone_device_name(unique_id);
if (!contact_to_sync.getContacts().isEmpty()) {
Sync_Contacts_To_Server(contact_to_sync);
}
}
