要取得联系人的姓名sample code如下:
final Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

while(people.moveToNext())
{
int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
}

要取得联系人的号码sample code如下:

        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 hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

            if (hasPhone.compareTo("1") == 0)
            {
                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));
                    String phoneTpye = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));

                    Log.d(TAG,"testNum="+ phoneNumber + "type:"+phoneTpye);
                }
                phones.close();
            }
            Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null);
            while (emails.moveToNext())
            {
                String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
                String emailType = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));

                Log.d(TAG,"testNum="+ emailAddress + "type:"+emailType);
            }
            emails.close();
        }
        cursor.close();
