Question

有没有办法从匿名函数中继承多个变量？我知道只是继承一个数组，但我很好奇是否有另一种方法来继承除使用数组之外的变量。

也许是这样的：

function($arg) use ($inherited1, $inherited2){
    // access the $inherited1 and $inherited2 variables directly 
}

你可以这样做

private void buildNotification() {

        Intent intentPlayPause = new Intent(NOTIFICATION_INTENT_PLAY_PAUSE);
        Intent intentOpenPlayer = new Intent(NOTIFICATION_INTENT_OPEN_PLAYER);
        Intent intentCancel = new Intent(NOTIFICATION_INTENT_CANCEL);

        PendingIntent playPausePending = PendingIntent.getBroadcast(this, 23, intentPlayPause, 0);
        PendingIntent openPending = PendingIntent.getBroadcast(this, 31, intentOpenPlayer, 0);
        PendingIntent cancelPending = PendingIntent.getBroadcast(this, 12, intentCancel, 0);


        RemoteViews mNotificationTemplate = new RemoteViews(this.getPackageName(), R.layout.notification);
        Notification.Builder notificationBuilder = new Notification.Builder(this);

        if (artImage == null)
            artImage = BitmapFactory.decodeResource(getResources(), R.drawable.default_art);

        mNotificationTemplate.setTextViewText(R.id.notification_line_one, singerName);
        mNotificationTemplate.setTextViewText(R.id.notification_line_two, songName);
        mNotificationTemplate.setImageViewResource(R.id.notification_play, isPlaying() ? R.drawable.btn_playback_pause : R.drawable.btn_playback_play);
        mNotificationTemplate.setImageViewBitmap(R.id.notification_image, artImage);

        mNotificationTemplate.setOnClickPendingIntent(R.id.notification_play, playPausePending);




        Notification notification = notificationBuilder
                .setSmallIcon(smallImage)
                .setContentIntent(openPending)
                .setPriority(Notification.PRIORITY_DEFAULT)
                .setContent(mNotificationTemplate)
                .setUsesChronometer(true)
                .build();


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {

            RemoteViews mExpandedView = new RemoteViews(this.getPackageName(), R.layout.notification_expanded);

            mExpandedView.setTextViewText(R.id.notification_line_one, singerName);
            mExpandedView.setTextViewText(R.id.notification_line_two, songName);
            mExpandedView.setImageViewResource(R.id.notification_expanded_play, isPlaying() ? R.drawable.btn_playback_pause : R.drawable.btn_playback_play);
            mExpandedView.setImageViewBitmap(R.id.notification_image, artImage);

            mExpandedView.setOnClickPendingIntent(R.id.notification_expanded_play, playPausePending);

            notification.bigContentView = mExpandedView;
        }

        if (mNotificationManager != null)
            mNotificationManager.notify(NOTIFICATION_ID, notification);

    }
