Android 更改通知的图像时出错

我有个问题。我想更新我的通知，以便在单击时将“暂停”更改为“播放”图像。但我一直在犯这样的错误：

android.app.RemoteServiceException: Bad notification posted from package m.com.musicbox: Couldn't expand RemoteViews for:StatusBarNotification(pkg=m.com.musicbox user=UserHandle{0} id=522 tag=null score=0: Notification(pri=0 icon=7f020067 contentView=m.com.musicbox/0x7f03003d vibrate=null sound=null defaults=0x0 flags=0x2 when=1416463928948 ledARGB=0x0 contentIntent=Y deleteIntent=N contentTitle=N contentText=N tickerText=N kind=[null]))

对于

RemoteView

、

NotificationManager

和

Notification

，我使用的与更新之前相同的方法。我不确定这是否是正确的方法，因为我仍在尝试找到解决方案。希望有人能帮忙。下面是我的代码：

void updateNotification() {

    if (Utils.isStatus.equalsIgnoreCase("pause")) {
        notificationView.setImageViewResource(R.id.play, R.drawable.ic_pause);
    } else {
        notificationView.setImageViewResource(R.id.play, R.drawable.ic_play);
    }
    notificationManager.notify(id, notification);
}


public void setNotification() {
    String ns = Context.NOTIFICATION_SERVICE;
    notificationManager = (NotificationManager) getSystemService(ns);

    notification = new Notification(R.drawable.ic_launcher, null,
            System.currentTimeMillis());

    notificationView = new RemoteViews(getPackageName(),
            R.layout.notification_bar);

    Intent notificationIntent = new Intent(context, Player.class);
    PendingIntent pendingNotificationIntent = PendingIntent.getActivity(
            this, 0, notificationIntent, 0);

    notification.contentView = notificationView;
    notification.contentIntent = pendingNotificationIntent;
    notification.flags |= Notification.FLAG_ONGOING_EVENT;

    Intent intentPlay = new Intent("m.com.musicbox.ACTION_PLAY");
    PendingIntent pendingPlayIntent = PendingIntent.getBroadcast(context,
            100, intentPlay, 0);

    Intent intentPrev = new Intent("m.com.musicbox.ACTION_PREVIOUS");
    PendingIntent pendingPrevIntent = PendingIntent.getBroadcast(context,
            100, intentPrev, 0);

    Intent intentNext = new Intent("m.com.musicbox.ACTION_NEXT");
    PendingIntent pendingNextIntent = PendingIntent.getBroadcast(context,
            100, intentNext, 0);

    Intent intentClose = new Intent("m.com.musicbox.ACTION_CLOSE");
    PendingIntent pendingCloseIntent = PendingIntent.getBroadcast(context,
            100, intentClose, 0);

    notificationView.setOnClickPendingIntent(R.id.play, pendingPlayIntent);
    notificationView.setOnClickPendingIntent(R.id.prev, pendingPrevIntent);
    notificationView.setOnClickPendingIntent(R.id.next, pendingNextIntent);
    notificationView
            .setOnClickPendingIntent(R.id.close, pendingCloseIntent);

    notificationManager.notify(id, notification);

}

你应该这样做：

void updateNotification() {

    Notification notification;
    long when = System.currentTimeMillis();

    if (Utils.isStatus.equalsIgnoreCase("pause")) {
        notification = new Notification(R.drawable.pause, "String message", when);
    } else {
        notification = new Notification(R.drawable.play, "String message", when);
    }
    notificationManager.notify(id, notification);
}

您是否尝试过像这样“notification.icon=R.drawable.icon；”我正在使用自定义布局，并希望在单击图像时更改图像。所以我想我不能使用你的方法，因为我需要原始图像的参考。我更新了关于如何设置通知的代码。
