        setContentView(R.layout.contact);
        TextView txt = (TextView)findViewById(R.id.con);
        String msg = "";

        ContentResolver cr = getContentResolver();
        Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
        while (cursor.moveToNext()) {
                String name = cursor.getString(cursor.getColumnIndexOrThrow(People.NAME));
                String number = cursor.getString(cursor.getColumnIndexOrThrow(People.NUMBER));
                String email = cursor.getString(cursor.getColumnIndexOrThrow(People.PRIMARY_EMAIL_ID));

                msg += name + " " + number + " " + email + "\n";
        }
        txt.setText(msg.toString());
    }
}

I am developing an application in which the application is able to send an email containing all the current phone contacts (name + phone number) as a backup alternative. I am trying out on how to extract all the phone contacts information and display them on the TextView... But I cannot do it, someone please consult me. Thanks...

使用ContactsContract.CommonDataKinds.Phone.CONTENT_URI而不是ContactsContract.Contacts.CONTENT_URI这样您就可以获得电话号码，并更改这些行

String name = cursor.getString(cursor.getColumnIndexOrThrow(People.NAME));
String number = cursor.getString(cursor.getColumnIndexOrThrow(People.NUMBER));
String email = cursor.getString(cursor.getColumnIndexOrThrow(People.PRIMARY_EMAIL_ID));

至

String name = cursor.getString(cursor.getColumnIndexOrThrow(Phone.DISPLAY_NAME));
String number = cursor.getString(cursor.getColumnIndexOrThrow(Phone.NUMBER));

您将需要另一个查询来获取 email_id。从第一个光标中，您可以像这样获取联系人 ID

long contactId = cursor.getLong(cursor.getColumnIndexOrThrow(Phone.CONTACT_ID));

contactId现在使用过滤器中的查询电子邮件 uri

long emailId;
Cursor cur = getContentResolver()
                    .query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
                     new String[]{"_id"},
                     "contact_id = " + contactId,
                     null,null);
if(cur != null && cur.moveToFirst()){
    emailId = cur.getLong(0);
}
