android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<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;

        }
