系统短信库的一些用法

1、查询所有短信，按发件人进行分组

Cursor  mCursor =                      managedQuery(Uri.parse("content://sms"),                          new String[] {"_id,address,date,read,status,type,body,count(address) as "                              + "totleCount from (select _id,substr(address,4) as address,date,read,status,type,body "                              + "from sms where address like \"+86%\" union select _id,address,date,read,status,type,body "                              + "from sms where address not like \"+86%\") r group by r.address order by r.date desc --"},                          null,                          null,                          null);

2、删除一个联系人的所有短信会话,包括+86的号码

    /**       * 删除一个联系人的所有短信会话,包括+86的号码       * @param phone       */      public int deleteMsgSession(Context context, String phone)      {          String phoneBytitle = "";          if (!phone.startsWith("+86"))          {              phoneBytitle = "+86" + phone;          }          else          {                  phoneBytitle = phone.substring(3);          }                    Cursor cursor =              context.getContentResolver()                  .query(Uri.parse("content://sms"), new String[] {"distinct thread_id"}, "address = ? or address = ?", new String[] {phone, phoneBytitle}, null);          List list = new ArrayList();          if (null != cursor)          {              if (cursor.moveToFirst())              {                  do                  {                      int thread_id = cursor.getInt(0);                      list.add(String.valueOf(thread_id));                    } while (cursor.moveToNext());              }          }           if (null != cursor)          {              cursor.close();              cursor = null;          }                  int size = list.size();          if(size == 0)          {              return -1;          }          else          {              int num = 0;              for (int i = 0; i < size; i++)              {                  int res = context.getContentResolver().delete(Uri.parse("content://sms/conversations/" + list.get(i)),                      null, null);                  num = num + res;              }  //            System.out.println("sms_num:" + num);              return num;          }      }

3、向系统库插入短信、版本不同插入的字段有所区别

 

 /**       * 将发送的短信保存到系统短信库中       */      private void foreverSendMsg(String content)      {          ContentValues values = new ContentValues();          //系统SDK的版本号          String sdkVersion = android.os.Build.VERSION.SDK;          try          {              // 发送时间              values.put("date", System.currentTimeMillis());              // 阅读状态              values.put("read", 1);              // 送达号码              values.put("address", phoneNumberTextView.getText().toString());              // 送达内容              values.put("body", content);                         //SDK为2.1时，插入的字段              if(ConstValue.SDK_VERSION == Integer.valueOf(sdkVersion))              {                  values.put("status", -1);                  values.put("type", 2);  //                values.put("locked", 0);              }              else              {                  // 设置可见                values.put("seen", 1);              }                         getContentResolver().insert(Uri.parse("content://sms/sent"), values);          }          catch (Exception e)          {              e.printStackTrace();          }          finally          {              values = null;          }
