我正在尝试使用他们的电话和电子邮件详细信息获取联系人列表，以将它们显示在列表中。我现在所做的是做三个单独的查询。

  1. 从 Contacts.CONTENT_URI 获取到 contactCursor 的联系人列表
  2. 从 Phone.CONTENT_ITEM_TYPE 获取所有电话号码到 phoneCursor
  3. 从 Email.CONTENT_ITEM_TYPE 获取所有电子邮件到 emailCursor

然后我将循环通过contactCursor。对于每个联系人，我将遍历 phoneCursor 和 emailCursor 以获取主要电话号码和电子邮件。但这需要一些时间来加载，并且在联系人数量很大时清晰可见。有什么方法可以让我在第一步中获得所有这些细节。

下面是代码片段：

    Cursor contacts = resolver.query(Contacts.CONTENT_URI, 
            CONTACT_PROJECTION, Contacts.HAS_PHONE_NUMBER + " != 0", null, Contacts._ID + " ASC");
    Cursor phone = resolver.query(Data.CONTENT_URI, PHONE_PROJECTION, 
            Data.MIMETYPE + "=? ", 
            new String[]{Phone.CONTENT_ITEM_TYPE}, 
            Data.CONTACT_ID + " ASC");

    Cursor email = resolver.query(Data.CONTENT_URI, EMAIL_PROJECTION, 
            Data.MIMETYPE + "=? ", 
            new String[]{Email.CONTENT_ITEM_TYPE}, 
            Data.CONTACT_ID + " ASC");

    if (contacts!=null && contacts.moveToFirst()) {
        do {

            String contactId = contacts.getString(0);

            if(phone!=null && phone.moveToFirst()){
                do{
                    if(contactId.equalsIgnoreCase(phone.getString(0))){
                        contact.setMobile(phone.getString(1));

                        break;
                    }
                }while(phone.moveToNext());
            }

            if(email!=null && email.moveToFirst()){
                do{
                    if(contactId.equalsIgnoreCase(email.getString(2))){
                        contact.setEmailWork(email.getString(1));
                        break;
                    }
                }while(email.moveToNext());
            }



        } while (contacts.moveToNext());

下面是获取所有联系人（包括电子邮件）的代码。

private void getContacts() {
        ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
        String id = null, name = null, email = null, phone = null, note = null, orgName = null, title = null;
        String Phone1 = "unknown", Phone2 = "unknown", Phone3 = "unknown", type1 = "unknown", type2 = "unknown", type3 = "unknown";
        int size = cur.getCount();
        StringBuilder addbuffer = null;
        if (cur.getCount() > 0) {
            int cnt = 1;
            while (cur.moveToNext()) {
                email = "";
                name = "";
                cnt++;
                id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
                name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

                if (name != null && name != "") {
                    // if (!checkEmail(name)) {
                    // email = "";
                    //
