android - 未决 Intent 未收到不同 notificationId 的 putExtraBudle

Question

我正在使用 PingService.java 的代码 https://github.com/android/platform_development/blob/master/samples/training/notify-user/src/com/example/android/pingme/PingService.javaPingService.Java

/**
  * PingService creates a notification that includes 2 buttons: one to snooze the
  * notification, and one to dismiss it.
  */

public class PingService extends IntentService {

private NotificationManager mNotificationManager;
private String mMessage;
private int mMillis;
NotificationCompat.Builder builder;

public PingService() {

    // The super call is required. The background thread that IntentService
    // starts is labeled with the string argument you pass.
    super("com.example.android.pingme");
}

@Override
protected void onHandleIntent(Intent intent) {
    // The reminder message the user set.
    mMessage = intent.getStringExtra(CommonConstants.EXTRA_MESSAGE);
    // The timer duration the user set. The default is 10 seconds.
    mMillis = intent.getIntExtra(CommonConstants.EXTRA_TIMER,
            CommonConstants.DEFAULT_TIMER_DURATION);
    NotificationManager nm = (NotificationManager)
            getSystemService(NOTIFICATION_SERVICE);

    String action = intent.getAction();
    // This section handles the 3 possible actions:
    // ping, snooze, and dismiss.
    if(action.equals(CommonConstants.ACTION_PING)) {
        issueNotification(intent, mMessage);
    } else if (action.equals(CommonConstants.ACTION_SNOOZE)) {
        nm.cancel(CommonConstants.NOTIFICATION_ID);
        Log.d(CommonConstants.DEBUG_TAG, getString(R.string.snoozing));
        // Sets a snooze-specific "done snoozing" message.
        issueNotification(intent, getString(R.string.done_snoozing));

    } else if (action.equals(CommonConstants.ACTION_DISMISS)) {
        nm.cancel(CommonConstants.NOTIFICATION_ID);
    }
}

private void issueNotification(Intent intent, String msg) {
    mNotificationManager = (NotificationManager)
            getSystemService(NOTIFICATION_SERVICE);

    // Sets up the Snooze and Dismiss action buttons that will appear in the
    // expanded view of the notification.
    Intent dismissIntent = new Intent(this, PingService.class);
    dismissIntent.setAction(CommonConstants.ACTION_DISMISS);
    PendingIntent piDismiss = PendingIntent.getService(this, 0, dismissIntent, 0);

    Intent snoozeIntent = new Intent(this, PingService.class);
    snoozeIntent.setAction(CommonConstants.ACTION_SNOOZE);
    PendingIntent piSnooze = PendingIntent.getService(this, 0, snoozeIntent, 0);

    // Constructs the Builder object.
    builder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_stat_notification)
            .setContentTitle(getString(R.string.notification))
            .setContentText(getString(R.string.ping))
            .setDefaults(Notification.DEFAULT_ALL) // requires VIBRATE permission
            /*
             * Sets the big view "big text" style and supplies the
             * text (the user's reminder message) that will be displayed
             * in the detail area of the expanded notification.
             * These calls are ignored by the support library for
             * pre-4.1 devices.
             */
            .setStyle(new NotificationCompat.BigTextStyle()
                 .bigText(msg))
            .addAction (R.drawable.ic_stat_dismiss,
                    getString(R.string.dismiss), piDismiss)
            .addAction (R.drawable.ic_stat_snooze,
                    getString(R.string.snooze), piSnooze);

    /*
     * Clicking the notification itself displays ResultActivity, which provides
     * UI for snoozing or dismissing the notification.
     * This is available through either the normal view or big view.
     */
     Intent resultIntent = new Intent(this, ResultActivity.class);
     resultIntent.putExtra(CommonConstants.EXTRA_MESSAGE, msg);
     resultIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

     // Because clicking the notification opens a new ("special") activity, there's
     // no need to create an artificial back stack.
     PendingIntent resultPendingIntent =
             PendingIntent.getActivity(
             this,
             0,
             resultIntent,
             PendingIntent.FLAG_UPDATE_CURRENT
     );

     builder.setContentIntent(resultPendingIntent);
     startTimer(mMillis);
}

private void issueNotification(NotificationCompat.Builder builder) {
    mNotificationManager = (NotificationManager)
            getSystemService(NOTIFICATION_SERVICE);
    // Including the notification ID allows you to update the notification later on.
    mNotificationManager.notify(CommonConstants.NOTIFICATION_ID, builder.build());
}


  private void startTimer(int millis) {
    Log.d(CommonConstants.DEBUG_TAG, getString(R.string.timer_start));
    try {
        Thread.sleep(millis);

    } catch (InterruptedException e) {
        Log.d(CommonConstants.DEBUG_TAG, getString(R.string.sleep_error));
    }
    Log.d(CommonConstants.DEBUG_TAG, getString(R.string.timer_finished));
    issueNotification(builder);
}
 }

---

 Intent mServiceIntent = new Intent(context.getApplicationContext(),             PingService.class);
    mServiceIntent.putExtra(Const.EXTRA_MESSAGE, "" + msg);
    mServiceIntent.putExtra(Const.ID, reminder_id);
    startService(mServiceIntent);

并将数据传递给 Action Button Intent 的 issueNotification 方法，例如

   Intent dismissIntent = new Intent(this, PingService.class);
    dismissIntent.setAction(CommonConstants.ACTION_DISMISS);
    dismissIntent.putExtra(CommonConstants.ID, reminder_id);
    PendingIntent piDismiss = PendingIntent.getService(this, 0,   dismissIntent, 0);

    Intent snoozeIntent = new Intent(this, PingService.class);
    snoozeIntent.setAction(CommonConstants.ACTION_SNOOZE);
    snoozeIntent.putExtra(CommonConstants.ID, reminder_id);
    PendingIntent piSnooze = PendingIntent.getService(this, 0, snoozeIntent, 0);

但是我没有从 issueNotification 获取 Action 按钮的 Click 事件时的 ID 并在 onHandleIntent 方法中传递 Intent

它在通知生成后自动设置为 1，由于在 PendingIntent 的 putExtra 中设置了错误的通知 ID，我无法取消该通知

我正在尝试传递不同的标志，例如

 PendingIntent piDismiss = PendingIntent.getService(this, 0, taken_intent,     PendingIntent.FLAG_UPDATE_CURRENT);

请帮助我，我已经尝试了很长时间，但没有得到正确的 ID。我的 putExtra 以某种方式被 1 覆盖....

提前谢谢你

Answer 1

经过如此多的研究终于找到了一个解决方案，我需要在 pending intent 中传递不同的代码，比如

PendingIntent piDismiss = PendingIntent.getBroadcast(this, CommonConstants.NOTIFICATION_ID,   dismissIntent, 0);

在每个 Action Button 案例中都是动态的和独特的。使用广播接收器代替服务 (getBroadcast) 来实现这一点。

谢谢。
