Call the Contacts Database in Android (froyo) to add, delete, modify, and query contacts and groups. The effect diagram and source code are provided.

Note: ThisProgramBased on froyo. The program contains some froyo built-in contacts source code. The project code is UTF-8, based on 2.2

Main content:

1. add, delete, modify, and query contacts:

Quickcontactbadge is used when all contacts are displayed;

When displaying the details of a contact, quickcontactbadge + checkbox (the pentagram) + listview is used.

You can set an avatar for editing and creating contacts, and add multiple types of phone, email, and other information. the type of information is the same as that of froyo contacts.

Ii. Group Function

You can move contacts to or from a group;

This program differs from other programs:

The addition, deletion, modification, and query functions are relatively complete.

The information that can be added when creating a contact is consistent with the built-in contacts.

Creating and editing the Contact Interface and grouping are the highlights of this program.

I believe that it will definitely help you understand Android contacts!
