Android Address Book Management three short-term acquisition and delivery of short-interest

The first two blogs and the knowledge to get contacts and call records, this article mainly introduces the knowledge of SMS, SMS in communication management should be said to be a difficult point, because SMS involves short-interest sessions and SMS details of two parts, and SMS data volume is larger, You can use the Asyncqueryhandler framework to query, while using CursorAdapter to bind the data

Text messages can be used to get the contact's avatar and name. This is implemented in the Code tool class, displays the name if the contact exists, otherwise displays the number, or displays the avatar if the contact avatar is present, otherwise displays the default avatar, as shown in the slice. Both of these functions can be implemented in contacts and call logs, and interested children's shoes can be modified.

Query Framework
