Android Address Book Management 3 short message acquisition and Sending Short Messages

The first two blogs respectively talked about how to obtain contacts and call records. This topic describes how to get short messages. Short Messages are a difficult point in communication management, because SMS involves two parts: Short Message session and text message details, and the text message data volume is large, you can use AsyncQueryHandler framework to query and use CursorAdapter to bind data.

You can obtain the contact's profile picture and name in the text message. This is implemented in the Code tool class. If a contact exists, the name is displayed. Otherwise, the number is displayed. If a contact profile exists, the Avatar is displayed. Otherwise, the default profile is displayed. These two functions can be implemented in contacts and call records, and can be modified if you are interested.
