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<String> list = new ArrayList<String>();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;}
