短信-选择-联系人

1.联系人存储业务bean

ContactInfo.java

2.ContactInfoSer.java

读取系统联系人数据库contacts.db 查找需要表字段 raw_contacts,data；

返回List<ContactInfo> contactInfos = new ArrayList<ContactInfo>(); 找到的联系人数据集合

3.ListContact.java

1.接收返回的联系人list集合。

2.设置adapter 讲数据显示在 list item

lv_select_contact.setAdapter(new ContactAdapter());

private class ContactAdapter extends BaseAdapter{}

3.设置list item 监听完成单击时返回单击的item数据

lv_select_contact.setOnItemClickListener(new OnItemClickListener(){});

MainActivity.java-获取返回的值

. Intent intent = new Intent(this,ListContact.class);

startActivityForResult(intent, 0);//获取新activity返回的值

重载 onActivityResult() 当创建的activity关闭时，调用此方法；并把数据 Intent data 传递給调用它的activity
