MTK短消息编程

 

1.获取短消息,

MTK没有专门用于获取短消息内容的函数,这给我们操作短消息带来了不便.比如有时我们需要分析短消息的内容,再比如有时要把短消息写入T卡了,再或者有时要把某条短消息显示到某些应用场合了,这时就需要获取短消息的内容.这里提供一个我经常使用的接口:

#include "SMSApi.h"
#include "med_utility.h"
extern unsigned short mmi_frm_sms_show_list_index[];
S8 g_sms_buffer[160] = {0};
char *ConvertString(char * str)
{
 char temp;
 int i;
       int len = wstrlen(str);
   
 for (i = 0; i < len ; i += 2)
 {
            temp = str[i];
      str[i] = str[i+1];
      str[i+1] = temp;
 }
 
 return str;
}
int wstrlen(char * txt)
{
 int lenth=0;
 unsigned char * ss=(unsigned char*)txt;

 while(((*ss<<8)+*(ss+1))!=0)
 {
  lenth+=2;
  ss+=2;
 }
 return lenth;
}

void my_msg_get_msg_rsp(void* data, module_type mod, U16 result)
{
 //U8 type=*(U8*)data;
 EMSData* pEms;
 int len = 0;
 
 GetEMSDataForView (&pEms, 0); 

 len = wstrlen((char *)(pEms->textBuffer))+2;

//把获取的信息复制到g_sms_buffer以备使用
 if (len < 20)
 {
  memcpy(g_sms_buffer, pEms->textBuffer, len);
 }
 else
 {
  memcpy(g_sms_buffer, pEms->textBuffer, 20);
 }
}
// type: MMI_FRM_SMS_APP_INBOX, MMI_FRM_SMS_APP_OUTBOX, MMI_FRM_SMS_APP_DRAFTS
// index: 0~0XFF
S32 my_msg_get_msg_req (U8 type, U16 req_index, E_MTPNP_AD_FILTER_RULE  cur_sim)
{
 int count =0;
 U16 index;
 /* disallow re-entering SMS application when there is a pending SMS job running in the background */
 if(mmi_frm_sms_check_action_pending())
 {
  return 1;
 }
 
#ifdef __MMI_DUAL_SIM_MASTER__
 if(cur_sim == MTPNP_AD_FILTER_MASTER)
 {
  MTPNP_AD_SMS_Set_Filter_Rule(MTPNP_AD_FILTER_MASTER);
  count =MTPNP_PFAL_SMS_Get_SMS_List_Size(type);
 }
 else
 {
  MTPNP_AD_SMS_Set_Filter_Rule(MTPNP_AD_FILTER_SLAVE);
  count = MTPNP_PFAL_SMS_Get_SMS_List_Size(type);
 }
 
 if((count <=0)||(req_index >= count))
 {
  return -1;
 }
 
 MTPNP_PFAL_SMS_Set_Current_Index(req_index);
 index = mmi_frm_sms_show_list_index[req_index];
#else
 index = req_index;
#endif  

 mmi_frm_sms_read_sms(my_msg_get_msg_rsp, MOD_MMI, type, index, MMI_TRUE);

 return 0;
}

2.发短信,有时我们需要向网络或者别的基站发送一条自填充内容的短信.比如订阅某种服务,或者查询话费,或者定时发送短信,或者拒接电话时给MT发一条提示短信等场合.函数有5个参数,mobileNo为手机号码,ASC类型字串,mobileNoLen号码长度,smsMsg短消息内容,应为UCS2编码,smsMsgLen长度,simid双卡情况下,0为主卡,1为副卡

#include "SMSApi.h"
#include "ProtocolEvents.h"
#ifndef __MMI_DUAL_SIM_MASTER__
void my_send_sms(S8 mobileNo[], U32 mobileNoLen, U8 smsMsg[], U32 smsMsgLen)
#else
void my_send_sms(S8 mobileNo[], U32 mobileNoLen, U8 smsMsg[], U32 smsMsgLen,
U8 simid)

#endif
{
 
 mmi_sms_send_msg_req_struct *sendSms;
 
 sendSms = (mmi_sms_send_msg_req_struct*)OslConstructDataPtr(sizeof(*sendSms));
 
 sendSms->dcs = SMSAL_UCS2_DCS;
 sendSms->udhi = 0;
 sendSms->length = smsMsgLen;
 memset(sendSms->msg,0,SMSAL_MAX_MSG_LEN);
 
 memcpy(sendSms->msg,smsMsg,sendSms->length);
 
 sendSms->profile = 0;
 sendSms->para = 0;
 sendSms->reply_index = MMI_FRM_SMS_INVALID_INDEX;
 sendSms->dest.type = CSMCC_DEFAULT_ADDR_TYPE;
 memset((S8*)sendSms->dest.number,0,MAX_CC_ADDR_LEN);
 
 sendSms->dest.length = mobileNoLen;
 memcpy(sendSms->dest.number,mobileNo,sendSms->dest.length);
 
 sendSms->seq_num = 0;
 sendSms->mms_mode = 0;

//  simsp_set_sms_ProtocolEventHandler();
#ifndef __MMI_DUAL_SIM_MASTER__
 mmi_frm_sms_send_message(MOD_MMI,MOD_L4C,0,PRT_MSG_ID_MMI_SMS_SEND_MSG_REQ,(
oslParaType*)sendSms,NULL);

#else//__MMI_DUAL_SIM_MASTER__
  
 if(simid == 0)
 {
  mmi_frm_sms_send_message(MOD_MMI, MOD_L4C, 0,PRT_MSG_ID_MMI_SMS_SEND_MSG_REQ
, (oslParaType *)sendSms, NULL);

 }
 else
 {
  MTPNP_PFAL_Send_Message_Segment((void *)sendSms);
 } 
#endif//__MMI_DUAL_SIM_MASTER__
}
