如何读取和显示交易消息从收件箱到android应用程序

Question

我已经知道如何从收件箱中读取消息，但我想实现一个android应用程序到只读交易消息并在列表视图中显示它与交易金额，信用卡借记卡等。当前完整的代码获取短信数据。如何根据需要过滤短信数据。

public List<SmsInfo> getSmsInfo() {
        String[] projection = new String[] { "_id", "address", "person",
                "body", "date", "type" };
//      @SuppressWarnings("deprecation")
//      Cursor cursor = activity.managedQuery(uri, projection, null, null,
//              "date desc");
        ContentResolver cr = activity.getContentResolver();
        Cursor cursor = cr.query(uri, projection, null, null, "date desc");
        int nameColumn = cursor.getColumnIndex("person");
        int phoneNumberColumn = cursor.getColumnIndex("address");
        int smsbodyColumn = cursor.getColumnIndex("body");
        int dateColumn = cursor.getColumnIndex("date");
        int typeColumn = cursor.getColumnIndex("type");
        if (cursor != null) {
            int i = 0;
            while (cursor.moveToNext() && i++ < 20) {
                SmsInfo smsInfo = new SmsInfo();
                smsInfo.setName(cursor.getString(nameColumn));
                smsInfo.setDate(dateFromLongToString(cursor.getString(dateColumn)));
                smsInfo.setPhoneNumber(cursor.getString(phoneNumberColumn));
                smsInfo.setSmsbody(cursor.getString(smsbodyColumn));
                smsInfo.setType(cursor.getString(typeColumn));
                String personName = getPeople2(smsInfo.getPhoneNumber());
                smsInfo.setName(null == personName ? smsInfo.getPhoneNumber()
                        : personName);
                infos.add(smsInfo);
            }
            cursor.close();
        }
        return infos;
    }

Answer 1

基本上跨国消息地址包含一些模式。例如。

AM-HDFCBK

因此，我用正则表达式来获取与模式相关的消息。

Pattern regEx =Pattern.compile("[a-zA-Z0-9] {2} [a-zA-Z0-9]{6}");

protected BroadcastReceiver myReceiver = new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
        final Bundle bundle = intent.getExtras();
        try {
            if (bundle != null) {
                final Object[] pdusObj = (Object[]) bundle.get("pdus");
                for (int i = 0; i < pdusObj.length; i++) {
                    SmsMessage currentMessage;
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        String format = bundle.getString("format");
                        currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i], format);
                        Log.e("Current Message", format + " : " + currentMessage.getDisplayOriginatingAddress());
                    } else {
                        currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    }
                    Pattern regEx =
                            Pattern.compile("[a-zA-Z0-9]{2}-[a-zA-Z0-9]{6}");
                    Matcher m = regEx.matcher(currentMessage.getDisplayOriginatingAddress());
                    if (m.find()) {
                        try {
                            String phoneNumber = m.group(0);
                            Long date = currentMessage.getTimestampMillis();
                            String message = currentMessage.getDisplayMessageBody();
                            Log.e("SmsReceiver Mine", "senderNum: " + phoneNumber + "; message: " + message);
                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                    } else {
                        Log.e("Mismatch", "Mismatch value");
                    }
                }
            }
        } catch (Exception e) {
            Log.e("SmsReceiver", "Exception smsReceiver" + e);
        }
    }
};

之后，您可以检查消息正文是否包含像credited , debited这样的单词，您可以访问它。

作为一个快速的想法，我想给你一些建议:

首先，从收件箱中对任何交易类型的消息进行排序将是相当具有挑战性的，您所能做的就是浏览每条消息并阅读正文并找到所需的消息列表，但这也不可行。

例如，您必须访问地址字段，并做必要的短信拥有所有字段，如:地址，正文，接收日期等。

也正如你提到的，你知道如何从收件箱中读取消息，我跳过了这一部分。附上一些链接，这可能会帮助你

读取事务消息:

private void readMessages(){
    final int textViewID = searchView.getContext().getResources().
            getIdentifier("android:id/search_src_text", null, null);
    final AutoCompleteTextView searchTextView = (AutoCompleteTextView)
            searchView.findViewById(textViewID);
    try {
        Field mCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
        mCursorDrawableRes.setAccessible(true);
        mCursorDrawableRes.set(searchTextView, 0); //This sets the cursor resource ID to 0 or @null which will make it visible on white background
    } catch (Exception e) {}

    SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
    String dateVal = "";
    Cursor cursor = this.getContentResolver().query(Uri.parse("content://sms/inbox"), null, null, null, null);
    if (cursor.moveToFirst()) { // must check the result to prevent exception
        do {
            String msgData = cursor.getString(cursor.getColumnIndexOrThrow("body")).toString();
            String date = cursor.getString(cursor.getColumnIndexOrThrow("date")).toString();
            Long dateV = Long.parseLong(date);
            int start = 0;
            int end = 0;
            String msg = "";
            String add = cursor.getString(2);
            dateVal = formatter.format(new Date(dateV));
            if(!(spam.contains(add) || promo.contains(add))) {
                if(msgData.contains("credited")|| msgData.contains("debited") || msgData.contains("withdrawn")) {
                    messages.add(dateVal + ":" + msgData + "axqw" + add);
                    contentMessage.add(msgData);
                }
            }
        } while (cursor.moveToNext());
    } else {
        // empty box, no SMS
    }
}

每个事务消息都具有以下特征:

1. 发送方的格式始终为XX-XXXX
2. 消息中会有一个/c, account no .
3. 将会有诸如可用平衡、可用平衡、平衡、组合平衡、可用平衡等关键词。
4. 将有交易关键字，如借记，贷记，付款。

如果你能结合所有这些条件，那么你会发现一个事务性消息。
