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。
