//删除短信
private void DeleteSMS()
{
/*
* 其中，delete方法中支持的协议为：
* SMS_ALL 根据参数中的条件删除sms表数据
* SMS_ALL_ID 根据_id删除sms表数据
* SMS_CONVERSATIONS_ID 根据thread_id删除sms表数据，可以带其它条件
* SMS_RAW_MESSAGE 根据参数中的条件删除 raw表
* SMS_STATUS_PENDING 根据参数中的条件删除 sr_pending表
* SMS_SIM 从Sim卡上删除数据
* 试一下SMS_CONVERSATIONS_ID："content://sms/conversations/3 "，删除thread_id="3", _id="5"的数据 在eclipse中的Emulator
* Control中，以13800给模拟器发送三条数据，然后以13900发送一条
* this.getContentResolver().delete
* (Uri.parse("content://sms/conversations/3"), "_id=?", new
* String[]{"5"}); 成功删除一条数据。
* 在数据库中每个发送者的thread_id虽然一样，但不是固定的，如果把一个发送者的全部数据删除掉，
* 然后换一个新号码发送短信时，thread_id是以数据库中最大的id+1赋值的。

看了一下android的源代码，sms支持的协议有：

sURLMatcher.addURI("sms", "#", SMS_ALL_ID);
sURLMatcher.addURI("sms", "inbox", SMS_INBOX);
sURLMatcher.addURI("sms", "inbox/#", SMS_INBOX_ID);
sURLMatcher.addURI("sms", "sent", SMS_SENT);
sURLMatcher.addURI("sms", "sent/#", SMS_SENT_ID);
sURLMatcher.addURI("sms", "draft", SMS_DRAFT);
sURLMatcher.addURI("sms", "draft/#", SMS_DRAFT_ID);
sURLMatcher.addURI("sms", "outbox", SMS_OUTBOX);
sURLMatcher.addURI("sms", "outbox/#", SMS_OUTBOX_ID);
sURLMatcher.addURI("sms", "undelivered", SMS_UNDELIVERED);
sURLMatcher.addURI("sms", "failed", SMS_FAILED);
sURLMatcher.addURI("sms", "failed/#", SMS_FAILED_ID);
sURLMatcher.addURI("sms", "queued", SMS_QUEUED);
sURLMatcher.addURI("sms", "conversations", SMS_CONVERSATIONS);
sURLMatcher.addURI("sms", "conversations/*", SMS_CONVERSATIONS_ID);
sURLMatcher.addURI("sms", "raw", SMS_RAW_MESSAGE);
sURLMatcher.addURI("sms", "attachments", SMS_ATTACHMENT);
sURLMatcher.addURI("sms", "attachments/#", SMS_ATTACHMENT_ID);

sURLMatcher.addURI("sms", "sim", SMS_ALL_SIM);
sURLMatcher.addURI("sms", "sim/#", SMS_SIM);*/

*
* 向sms表插入数据时，type是根据协议来自动设置，
* 如果传入的数据中没有设置date时，自动设置为当前系统时间；非SMS_INBOX协议时，read标志设置为1
* SMS_INBOX协议时，系统会自动查询并设置PERSON threadId为null或者0时，系统也会自动设置

* 一直为造不了"发送失败"的邮件而发愁，现在来做一个： content://sms/failed

* 同一个联系人的thread_id是一样的，通过遍历thread id和对比就能知道一个联系人有几条短信；

* address 发件人手机号码
* person 联系人列表里的序号，陌生人为null ；即rawcontact表的contact_id，或者contact表的_id；
