android - ContactsContract如何枚举所有可用字段？

Question

在我的应用程序中，我需要让用户有机会查看/编辑 ContactsContract 的所有可用字段。

我应该如何获取/查看所有可用字段 - 包括任何自定义字段？

Answer 1

首先获取手机中存在的所有人的姓名:

Cursor phones = getContentResolver().query(
                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                    null,
                    null,
                    null,
                    ContactsContract.Contacts.DISPLAY_NAME
                            + " COLLATE LOCALIZED ASC");
            while (phones.moveToNext()) {

                name = phones
                        .getString(phones
                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                namelist.add(name);
                String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                 number_list.add(phoneNumber);
            detaillist.put(name, phoneNumber);
            }
            phones.close();
}

现在获取联系人 ID 并使用联系人 ID 获取其他信息，如电话号码、电子邮件 ID、地址、组织:

protected void get_UserContactId(String item_clicked) 
        {
            System.out.println("i m in fincution contact id");
            ContentResolver localContentResolver = this.getContentResolver();
            Cursor contactLookupCursor =  
               localContentResolver.query(
                        Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, 
                        Uri.encode(item_clicked)), 
                        new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup._ID}, 
                        null, 
                        null, 
                        null);
            try {
            while(contactLookupCursor.moveToNext()){
              contactName = contactLookupCursor.getString(contactLookupCursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
                user_contact_id = contactLookupCursor.getString(contactLookupCursor.getColumnIndexOrThrow(PhoneLookup._ID));

                 System.out.println("contatc id id"+user_contact_id);

                }

            }
        finally {
            contactLookupCursor.close();
            } 

        }


protected void get_UserEmail(String item_clicked) 
        {
            Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + user_contact_id, null, null); 
            while (emails.moveToNext()) { 
               // This would allow you get several email addresses 
               user_email_id = emails.getString( 
               emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)); 
               String user_email_type=emails.getString( 
                       emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE)); 
               System.out.println("the email type"+user_email_type);
               System.out.println("email address might be"+emailAddress);
            contact_attribute_type.add(EMAIL_TYPE[(Integer.parseInt(user_email_type))-1]);
            contact_attribute_value.add(user_email_id);
            } 
            emails.close(); 

        }

        protected void get_UserNumber(String item_clicked) {
            // TODO Auto-generated method stub
            final String[] CONTACTS_SUMMARY_PROJECTION = new String[] {
                ContactsContract.Contacts._ID,
                ContactsContract.Contacts.DISPLAY_NAME,
                ContactsContract.Contacts.STARRED,
                ContactsContract.Contacts.TIMES_CONTACTED,
                ContactsContract.Contacts.CONTACT_PRESENCE,
                ContactsContract.Contacts.PHOTO_ID,
                ContactsContract.Contacts.LOOKUP_KEY,
                ContactsContract.Contacts.HAS_PHONE_NUMBER,
            };



            String select = "(" + ContactsContract.Contacts.DISPLAY_NAME + " == \"" +item_clicked+ "\" )";
            Cursor c = this.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, CONTACTS_SUMMARY_PROJECTION, select, null, ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
            this.startManagingCursor(c);

            if (c.moveToNext())
            {
                String id = c.getString(0);
                ArrayList<String> phones = new ArrayList<String>();

                Cursor pCur = this.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", new String[]{id}, null);
                while (pCur.moveToNext())
                {
                    phones.add(pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
                    user_number=pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                   String number_type=pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
                   System.out.println("the number type---"+number_type); 
                   System.out.println("user no. in share is"+user_number);
                   contact_attribute_type.add(PHONE_TYPE[(Integer.parseInt(number_type))-1]);
                   contact_attribute_value.add(user_number);
                 //   Log.i("", name_to_search+ " has the following phone number "+ pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));

                } 
                pCur.close();   
            }

            }


        protected String get_UserAddress() {
            // TODO Auto-generated method stub
            try { 

                System.out.println(" i m in user address");
            Cursor address = getContentResolver().query(ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,null, ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID + " = " + client_contact_id, null, null); 
                while (address.moveToNext()) { 
                   // This would allow you get several email addresses 
                  user_home_address = address.getString(

                } 
                address.close(); 
            }

                                    + ContactsContract.CommonDataKinds.Website.CONTENT_ITEM_TYPE
                                    + "'",null,null);

                            websiteNameCursor.moveToNext();

                            }
            }   




    }

通过这样做你可以获得contacts-contract的所有字段。
