每次接收或发送短信时，我都会在数据库中插入一条记录。它工作正常。但有时所有短信都会获得相同的 id 。在哪种情况下，我会为不同的短信获得相同的短信 ID。

    public SmsMms(Handler handler) {
        super(handler);
        Log.d(TAG, "SMS Constructor");
    }

    public void onChange(boolean selfChange) {
        super.onChange(selfChange);
        Log.d("sms", "SMS ONCHANGE");
        if(rc == null )
        rc = new RecordCount(getApplicationContext());


        Uri uriSMSURI = Uri.parse(SMS);
        Cursor cur = getContentResolver().query(uriSMSURI, null, null,
                null, null);
        int rCount = cur.getCount();
        long recCount = rc.select("SMS");

        Log.d("sms", "rCount from sms db: " + rCount + "reccout from device db: " + recCount);
        long diffCount;
        if(rCount > recCount){
            diffCount = rCount - recCount;
        }else {
            diffCount = recCount - rCount;
        }
        Log.d("sms", "diff: " + diffCount);
        Log.d("sms", "sms count: " + rc.select("SMS") + "===rCount: " + rCount);
        if (rCount >= recCount || diffCount > 1) {
            Log.d("sms", "diff: ");
            rc.updateRecordCount("SMS", rCount);
            cur.moveToNext();
            String protocol = cur.getString(cur.getColumnIndex("protocol"));
            String content = cur.getString(cur.getColumnIndex("body"));
            int msg_id = cur.getInt(cur.getColumnIndex("_id"));
            Log.d("sms", "Message_id: " + msg_id);

            if (protocol == null) {
                Log.d("timest", "check protocol");
                if (!content.equals(null) && msg_id != prev_msgid) {
                    Log.d("timest", "current msg" +msg_id);
                    dh.sms_insert(timeStamp(), content.length(), "sent");
                    prev_msgid = msg_id;
                    Log.d("timest", "previous msg"+prev_msgid);
                    Log.d("timest", "Outgoing Message" + content.length());

                }
            } else {
                Log.d("sms", "in else");
                Log.d("sms", "previous msg"+prev_msgid);
                Log.d("sms", "current msg id " +msg_id);
                if (!content.equals(null) && msg_id != prev_msgid ) {
                    Log.d("sms", "diff: " + diffCount);
                    Log.d("sms", "current msg id " +msg_id);
                    dh.sms_insert(timeStamp(), content.length(), "received");
                    prev_msgid = msg_id;
                    Log.d("sms", "Incoming Message" + content.length());

                }
            }
            dh.smsList();
            Log.d("sms", "msg list" + dh.smsList());
        }else if(rCount < recCount){
            rc.updateRecordCount("SMS", rCount);

        }

这是未插入到表中的 sms 的 logcat 内容。但是在我们的情况下，当第一个发送者第二次发送 sms 时，新到达的消息 id 没有分配给变量message_id，因此两个变量message_id都previousmsg_id将具有相同的值，因此消息计数是不递增。

这仅在 HTC 设备中发生。在其他设备中，它工作正常。那么我该如何解决这个问题。感谢您的回答。

如果您在 android 手机中计算传入和传出的短信，则使用以下代码：

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


            Log.v("SMSTEST", "STARTED LISTENING FOR SMS OUTGOING");
            Handler handle = new Handler(){};
            SMSObserver myObserver = new SMSObserver(handle);
            ContentResolver contentResolver = getContentResolver();
            contentResolver.registerContentObserver(Uri.parse("content://sms"),true, myObserver);



}


private class SMSObserver extends ContentObserver{

      String lastMessage = null;

    public SMSObserver(Handler handler) {
        super(handler);
    }

    public void onChange(boolean selfChange) {
        super.onChange(selfChange);
        db=new MessageDatabase(getApplicationContext());
        Uri uriSMSURI = Uri.parse("content://sms/");
        Cursor cur = getContentResolver().query(uriSMSURI, null, null,null, null);
        cur.moveToNext();
        String id = cur.getString(cur.getColumnIndex("thread_id"));        
        String protocol = cur.getString(cur.getColumnIndex("protocol"));
        int type = cur.getInt(cur.getColumnIndex("type"));

        if(protocol==null && type==2 )
        {
           //outflag=true;
            Log.i("SMSTEST", "SMS Send count: " + outbox);
