在Android中监听通知的超时，可以使用以下方法：

1. 创建一个BroadcastReceiver类来接收通知超时的广播：

public class NotificationTimeoutReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 处理通知超时的逻辑
        String notificationId = intent.getStringExtra("notificationId");
        // 根据notificationId取消相应的通知
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.cancel(notificationId);
    }
}

2. 在发送通知的地方设置超时的定时器，并发送通知：

// 设置通知超时时间
long timeoutMillis = 5000; // 5秒

// 创建PendingIntent，用于发送通知超时广播
Intent timeoutIntent = new Intent(context, NotificationTimeoutReceiver.class);
timeoutIntent.putExtra("notificationId", notificationId);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, timeoutIntent, PendingIntent.FLAG_CANCEL_CURRENT);

// 设置定时器，当超时时发送广播
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    alarmManager.setExactAndAllowWhileIdle(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + timeoutMillis, pendingIntent);
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    alarmManager.setExact(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + timeoutMillis, pendingIntent);
} else {
    alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + timeoutMillis, pendingIntent);
}

// 发送通知
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(notificationId, notification);

3. 在AndroidManifest.xml文件中注册BroadcastReceiver：

这样，当发送的通知超过指定的时间后，会触发BroadcastReceiver接收到通知超时的广播，然后在广播接收器中取消对应的通知。
