如果您发送的邮件在Android中成功发送,请通知您

Question

我这里有一些代码发送消息:

SmsManager sms = new SmsManager.getDefault();
sms.sendTextMessage("911", null, "HALP!", PendingIntent, null);

Developer.android说PendingIntent:

如果没有NULL这个PendingIntent当成功发送的消息是广播,还是失败.结果代码将Activity.RESULT_OK成功,或者其中一个错误:

RESULT_ERROR_GENERIC_FAILURE

RESULT_ERROR_RADIO_OFF

RESULT_ERROR_NULL_PDU

对于RESULT_ERROR_GENERIC_FAILURE该sentIntent可包括额外的"的errorCode"含有的无线技术特定的值,通常只对故障排除.

基于每个应用程序的SMS控制检查sentIntent.如果sentIntent是NULL,则将针对所有未知应用程序检查呼叫者,这导致在检查时段中发送较少数量的SMS.

我的问题是:如何让一个PendingIntent喂到sendTextMessage,仅仅显示了一个Toast说法或者消息被发送或没有？

谢谢.

这可以简单地通过注册您可以实现PendingIntent与BroadcastReceiver该通知您,当您的邮件发送成功,当它交付给收件人.请按照以下步骤_

1. 构建两个PendingIntent,一个用于发送,另一个用于传递通知.
2. 构建两个BroadcastReceiver.一个用于发送,另一个用于发送.
3. 最后,这些注册用的PendingIntent相应的广播接收器通过registerReceiver,因此,他们的 广播接收器得到通知并做needfull.

我已经构建了一个简单的类来完成我上面解释过的工作.你可以通过这门课程来完全理解它_

public class SendDeliverSMSActivity extends Activity {
Button btnSendSMS;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);
    btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
    btnSendSMS.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            // Your method that send sms
            sendSMS("5556", "Hi You got a message!");
        }
    });

}

/**
 * ---sends an SMS message to another device---
 * 
 * @param phoneNumber
 * @param message
 */
private void sendSMS(String phoneNumber, String message) {
    // Intent Filter Tags for SMS SEND and DELIVER
    String SENT = "SMS_SENT";
    String DELIVERED = "SMS_DELIVERED";
// STEP-1___
    // SEND PendingIntent
    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(
            SENT), 0);

    // DELIVER PendingIntent
    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
            new Intent(DELIVERED), 0);
// STEP-2___
    // SEND BroadcastReceiver
    BroadcastReceiver sendSMS = new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {
            case Activity.RESULT_OK:
                Toast.makeText(getBaseContext(), "SMS sent",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                Toast.makeText(getBaseContext(), "Generic failure",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_NO_SERVICE:
                Toast.makeText(getBaseContext(), "No service",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_NULL_PDU:
                Toast.makeText(getBaseContext(), "Null PDU",
                        Toast.LENGTH_SHORT).show();
                break;
            case SmsManager.RESULT_ERROR_RADIO_OFF:
                Toast.makeText(getBaseContext(), "Radio off",
                        Toast.LENGTH_SHORT).show();
                break;
            }
        }
    };

    // DELIVERY BroadcastReceiver
    BroadcastReceiver deliverSMS = new BroadcastReceiver() {
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode()) {
            case Activity.RESULT_OK:
                Toast.makeText(getBaseContext(), "SMS delivered",
                        Toast.LENGTH_SHORT).show();
                break;
            case Activity.RESULT_CANCELED:
                Toast.makeText(getBaseContext(), "SMS not delivered",
                        Toast.LENGTH_SHORT).show();
                break;
            }
        }
    };
// STEP-3___
    // ---Notify when the SMS has been sent---
    registerReceiver(sendSMS, new IntentFilter(SENT));

    // ---Notify when the SMS has been delivered---
    registerReceiver(deliverSMS, new IntentFilter(DELIVERED));

    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
 }
}

我希望这能帮到您!:)
