Question

我想发送多个短信。我有一个while循环，它从数据库中读取并将消息ID传递给广播接收器，将消息标记为已发送。如果我尝试发送多条消息，即使发送的消息不是第一条消息，广播也只接收第一条消息的ID。您可能希望广播接收器接收相应短信的ID，但事实并非如此。我该如何解决这个问题？

while (cursor.moveToNext()) {

            String _ID = cursor.getString(cursor.getColumnIndex(FeedContract.Entry._ID));
            int triesCount = cursor.getInt(cursor.getColumnIndex(FeedContract.Entry.TRIES_COUNT));
            triesCount += 1;

            Intent smsSentIntent = new Intent(Constants.SMS_SENT_BROADCAST_NAME);
            smsSentIntent.putExtra(FeedContract.Entry._ID, _ID);
            smsSentIntent.putExtra(FeedContract.Entry.TRIES_COUNT, triesCount);

            Intent smsDeliveredIntent = new Intent(Constants.SMS_DELIVERED_BROADCAST_NAME);
            smsDeliveredIntent.putExtra(FeedContract.Entry._ID, _ID);
            smsDeliveredIntent.putExtra(FeedContract.Entry.TRIES_COUNT, triesCount);

            ArrayList<PendingIntent> sentPendingIntents = new ArrayList<>();
            PendingIntent sentPI = PendingIntent.getBroadcast(context, 0, smsSentIntent, 0);

            ArrayList<PendingIntent> deliveredPendingIntents = new ArrayList<>();
            PendingIntent deliveredPI = PendingIntent.getBroadcast(context, 0, smsDeliveredIntent, 0);

            try {
                SmsManager sms = SmsManager.getDefault();
                ArrayList<String> mSMSMessage = sms.divideMessage(cursor.getString(cursor.getColumnIndex(FeedContract.Entry.SMS_BODY)));
                for (int i = 0; i < mSMSMessage.size(); i++) {
                    sentPendingIntents.add(i, sentPI);
                    deliveredPendingIntents.add(i, deliveredPI);
                }

                sms.sendMultipartTextMessage(cursor.getString(cursor.getColumnIndex(FeedContract.Entry.RECIPIENTS)), null, mSMSMessage, sentPendingIntents, deliveredPendingIntents);              

            } catch (Exception e) {
                e.printStackTrace();
            }

            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

        cursor.close();
    }

在广播接收器上我有以下内容。

@Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();
        String _ID = extras.getString(FeedContract.Entry._ID);   
        Toast.makeText(context, "Sent Message ID " + _ID, Toast.LENGTH_SHORT).show();   
        }

在意图中设置数据

Intent intent = new Intent(this, AlarmReceiver.class);
        intent.putExtra(INTENT_MEDICINE_KEY, medicineName);
        mPendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), REQUEST_CODE, intent, 0);

在onReceive（）

中

@Override
    public void onReceive(Context context, Intent intent) {

        String medName = intent.getStringExtra(ReminderActivity.INTENT_MEDICINE_KEY);

        NotificationManager  notificationManager = (NotificationManager)context.getSystemService(context.NOTIFICATION_SERVICE);

        Notification notification = new Notification(R.drawable.ic_launcher_notification, context.getString(R.string.medication_alarm), 
                System.currentTimeMillis());
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0, new Intent(context, MedicationActivity.class), 0);
        notification.setLatestEventInfo(context, context.getString(R.string.app_name), context.getString(R.string.notification_message)+" "+medName, 
                contentIntent);
        notificationManager.notify(R.string.alarm_tag, notification);

        // Vibrate the mobile phone
        Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
        vibrator.vibrate(2000);
    }

Android将数据传递给广播接收器不起作用
