Java 如何从联系人处获取当前联系人的电子邮件和电话号码？

代码：获取当前联系人的号码和姓名

public void test111(View view) {
    ContentResolver cr = getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, null);

    if (cur != null && cur.getCount() > 0) {
        while (cur.moveToNext()) {
            String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

            if (cur.getInt(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
                Cursor pCur = cr.query(
                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
                if (pCur != null) {
                    while (pCur.moveToNext()) {
                        String phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

                        Logger.log(MainActivity.class, "!!!!!!!!! Name : " + name + ", Phone No: " + phoneNo, Logger.ERROR);
                    }
                }
                if (pCur != null) {
                    pCur.close();
                }
            }
        }
    }
}

但在下一种情况下，如果我需要从当前联系人处获得电子邮件，我必须再创建一个

光标

Cursor cur1 = cr.query(
                    ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
                    ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
                    new String[]{id}, null);

它会返回可用电子邮件的列表，但不会返回当前联系人的电子邮件

public void test111(View view) {
    ContentResolver cr = getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, null);

    if (cur != null && cur.getCount() > 0) {
        while (cur.moveToNext()) {
            String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

            if (cur.getInt(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
                Cursor pCur = cr.query(
                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
                if (pCur != null) {
                    while (pCur.moveToNext()) {
                        String phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

                        Logger.log(MainActivity.class, "!!!!!!!!! Name : " + name + ", Phone No: " + phoneNo, Logger.ERROR);
                    }
                }
                if (pCur != null) {
                    pCur.close();
                }
            }
        }
    }
}

如果电子邮件不可用，我需要获得如下信息

名称、号码、电子邮件

如果电子邮件不可用

名称、号码、空
