Java语言lang.IllegalArgumentException:setShowActionsInCompactView:action 1超出界限(最大0)

illegalstateexception android-notifications media-player android

我正在为android中的一个广播应用程序构建媒体风格的通知。以下是我的通知代码:

NotificationCompat.Action action = new android.support.v4.app.NotificationCompat.Action.Builder(imgNotificationAction, "playPause", pendingIntent).build();
    //create new notification
    NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
            .setShowWhen(false)
            .setStyle(new NotificationCompat.MediaStyle()
                    .setMediaSession(mediaSession.getSessionToken())
                    .setShowActionsInCompactView(0, 1, 2))
            .setColor(ContextCompat.getColor(this, R.color.colorPrimary))
            //.setLargeIcon(largeIcon)
            .setSmallIcon(android.R.drawable.stat_sys_headset)
            .setContentText(radioName)
            .setContentTitle("Igala Radio presents")
            .setContentInfo("Igala language radio")
            .setContentIntent(pendingIntent)
            .addAction(action);

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(NOTIFICATION_ID, notificationBuilder.build());

但我在Log cat中遇到以下异常:

Caused by: java.lang.IllegalArgumentException: setShowActionsInCompactView: action 1 out of bounds (max 0)
                                                                 at android.app.Notification$MediaStyle.makeMediaContentView(Notification.java:4493)

我想知道为什么会这样 操作1超出界限(最大值0) . 这是否意味着我不能在其中添加任何操作?

我认为发生错误是因为您正在定义操作( addAction() )之后 setShowActionsInCompactView() .

这样,你就可以 setShowActionsInCompactView 什么时候 notificationBuilder 尚未执行任何操作。换句话说,它的内部数组有0个元素(最大值为0)

你能试试这样的方法吗:

NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
        .addAction(action)
        ...
        .setStyle(new NotificationCompat.MediaStyle()
                .setMediaSession(mediaSession.getSessionToken())
                .setShowActionsInCompactView(0, 1, 2))
        ....;

我发现的另一个错误是:

您只创建一个操作:

NotificationCompat.Action action = new android.support.v4.app.NotificationCompat.Action.Builder(imgNotificationAction, "playPause", pendingIntent).build();

但在这里,您要设置3个操作:

.setShowActionsInCompactView(0, 1, 2))

操作数 设置ShowActionsInCompactView() 应与通过添加的操作数相匹配 addAction() .

您可以添加更多操作(创建新操作并调用 addAction() 再次或仅向发送一个参数 设置ShowActionsInCompactView()
