Question

我有一个活动（称为 NMessageActivity ），其中包含发送短信的简单方法。只需使用此代码：

public void sendSMS(MBean dBean) {

    if (sentSMS != null && deliveredSMS != null) {
        SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage(dBean.getToInNumbers(), null,
                dBean.getMessage(), sentSMS, deliveredSMS);
    } else {
        ToastObject.postMessage("Error code 233!");
    }

}

在此之前，我确实初始化了我使用的 Pending Intents 。我把它们放在 onCreate方法我有：

smsSentReceiver = new SentReceiver(this);
smsDeliveredReceiver = new DeliveredReceiver(this);

然后我在 onResume（）：

注册它们

super.onResume();
registerReceiver(smsSentReceiver, new IntentFilter(TAG_SENT));
registerReceiver(smsDeliveredReceiver, new IntentFilter(TAG_DELIVERED));

并在 onPause（）我取消注册：

super.onPause();
unregisterReceiver(smsSentReceiver);
unregisterReceiver(smsDeliveredReceiver);

在发送短信之前，我准备 AlarmManager 来执行意图 2秒后使用此代码：

    MBean dbbean = new MBean(txt_destNum.getText().toString(), txt_date
            .getText().toString(), txt_time.getText().toString(),
            MBean.STATUS_WAIT, txt_msg.getText().toString());

    db.addMBean(dbbean);

    Intent intentAlarm = new Intent(TAG_SENT);
    Intent intentAlarm2 = new Intent(TAG_DELIVERED);

    // putting the values in
    intentAlarm.putExtra(MBean.MBEAN_NAME, dbbean.toString());

    sentSMS = PendingIntent.getBroadcast(getApplicationContext(), 0,
            intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT);

    deliveredSMS = PendingIntent.getBroadcast(getApplicationContext(),
            0, intentAlarm2, PendingIntent.FLAG_UPDATE_CURRENT);

    int sec = 2;

    // create the object
    AlarmManager alarmManager = (AlarmManager) getSystemService(getApplicationContext().ALARM_SERVICE);

    alarmManager.set(AlarmManager.RTC_WAKEUP,
            System.currentTimeMillis() + (sec * 1000), sentSMS);

问题不在于上述方法，也不在于AlarmManager。相反，问题出在我拥有的BroadcastReceiver上。从不调用广播接收器。为什么会这样？

以下是Broadcast Receiver类的详细信息：

SentReceiver.java

public class SentReceiver extends BroadcastReceiver {

    private MBean dBean;
    private Context dCont;
    private ToastSender dToast;
    private Activity dNMessageActivity;

    public SentReceiver(Activity obAct){
        dNMessageActivity = obAct;
    }

    private void sendMessage() {
        ((NMessageActivity)dNMessageActivity).sendSMS(dBean);
    }

    private void vibratePhone() {

        Vibrator vibrator = (Vibrator) dCont
                .getSystemService(Context.VIBRATOR_SERVICE);
        vibrator.vibrate(1000);

    }

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        dToast = new ToastSender(arg0);
        dCont = arg0;

        // TODO Auto-generated method stub
        switch (getResultCode()) {
        case Activity.RESULT_OK:
            // SMS has been sent
            dBean = new MBean(arg1.getStringExtra(MBean.MBEAN_NAME));

            vibratePhone();
            sendMessage();

            break;
        case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
            // Generic Failure

            dToast.postMessage("Error code 48!");

            break;
        case SmsManager.RESULT_ERROR_NO_SERVICE:
            // No Service

            dToast.postMessage("Error code 53!");

            break;
        case SmsManager.RESULT_ERROR_NULL_PDU:
            // Null PDU

            dToast.postMessage("Error code 58!");

            break;
        case SmsManager.RESULT_ERROR_RADIO_OFF:
            // Radio Off

            dToast.postMessage("Error code 63!");

            break;
        default:
            break;
        }

    }

}

和另一个接收者是

DeliveredReceiver.java

public class DeliveredReceiver extends BroadcastReceiver {

    private ToastSender dToast;
    private Context dCont;
    private Activity dNMessageActivity;

    public DeliveredReceiver(Activity obAct){
        dNMessageActivity = obAct;
    }

    private void vibratePhone() {

        Vibrator vibrator = (Vibrator) dCont
                .getSystemService(Context.VIBRATOR_SERVICE);
        vibrator.vibrate(2000);

    }

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        dCont = arg0;
        dToast = new ToastSender(arg0);

        switch (getResultCode()) {
        case Activity.RESULT_OK:
            dToast.postMessage("SMS Sent");

            vibratePhone();

            break;
        case Activity.RESULT_CANCELED:
            dToast.postMessage("SMS Pending");
            break;
        }
    }

}

我想知道广播接收器问题或我通过Alarmmanager传递的Pending Intent问题？为什么程序根本不调用广播接收器？

Alarmmanager发送短信广播接收器未调用
