如何仅在对话视图中使用最新的SMS? [英] How to get only most recent SMS to use in conversation view?

问题描述

我正在尝试创建短信对话列表.我正在使用以下代码来获取光标:

I am trying to create an sms conversation list. I am using this code to get a cursor:

Cursor cursor = activity.getContentResolver().query(Uri.parse("content://sms/inbox"), null, null, null, null); 

问题是，当我使用光标时，我从一个联系人那里收到多条消息.我试图仅从所有联系人中获取最新消息，以便可以在recyclerview中将其显示为对话列表.

The problem is that when I use the cursor, I get multiple messages from one contact. I am trying to get only the most recent message from all contacts so that I can show them in a recyclerview as a list of conversations.

提前谢谢！

推荐答案

查询"content://sms/conversations" URI( Telephony.Sms.Conversations.CONTENT_URI )将返回每个对话的摘要，其中"snippet" 列( Telephony.Sms.Conversations.SNIPPET )是每个对话中的最后一条消息.

Querying the "content://sms/conversations" URI (Telephony.Sms.Conversations.CONTENT_URI) will return a summary of each conversation, with the "snippet" column (Telephony.Sms.Conversations.SNIPPET) being the last message in each.

此查询还将返回一个"msg_count" 列( Telephony.Sms.Conversations.MESSAGE_COUNT )-这很不言自明-和一个"thread_id" 列( Telephony.Sms.Conversations.THREAD_ID )，可通过查询附加在对话URI上的ID来检索完整的对话.例如:

This query will also return with a "msg_count" column (Telephony.Sms.Conversations.MESSAGE_COUNT) - which is pretty self-explanatory - and a "thread_id" column (Telephony.Sms.Conversations.THREAD_ID), which can be used to retrieve a complete conversation, by querying with that ID appended to the conversations URI. For example:

String threadId = ...
Uri convoUri = Telephony.Sms.Conversations.CONTENT_URI
               .buildUpon().appendPath(threadId).build();

请注意，这些查询将仅返回SMS消息.如果还需要MMS，则 Telephony.Mms 和 Telephony.MmsSms 具有相似的URI.

Do note that these queries will return only SMS messages. If you want MMS as well, Telephony.Mms and Telephony.MmsSms have similar URIs.
