Java 如何从联系人列表中获取电子邮件地址？

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姓名，并显示在列表中。但我想要号码、姓名和电子邮件地址，所以请检查下面的代码

 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());

}

我为姓名、号码和电子邮件id创建了三个数组，但上面的代码我只得到了手机和姓名。当我在数组中添加姓名和手机号码时，请同时在电子邮件id数组中存储电子邮件id特定手机号码。因此，请帮助…

您可以使用此代码从联系人处获取电子邮件

public List getEmail（int contactId）{
List emailStr=new ArrayList（）；
ContentResolver cr=context.getContentResolver（）；
游标emailCur=cr.query(
ContactsContract.CommonDataTypes.Email.CONTENT\u URI，
无效的
ContactsContract.CommonDataTypes.Email.CONTACT_ID+“=？”，
新字符串[]{String.valueOf（contactId）}，null）；
while（emailCur.moveToNext（））{
String email=emailCur.getString(
emailCur.getColumnIndex（ContactsContract.CommonDataTypes.Email.DATA））；
emailStr.add（电子邮件）；
System.out.println（“电子邮件”+电子邮件）；
}
emailCur.close（）；
返回emailStr；
}

使用以下代码从一个联系人和电话簿中的所有联系人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

                        ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
                        new String[]{id}, null);
                while (emailCur.moveToNext()) {
