我无法让Android的Big Text通知按照此处的说明运行:NotificationCompat.BigTextStyle。这是我用来显示通知的代码。我知道所有数据都正确回归,因为我可以将它显示在控制台上,并作为传统的内容文本和标题。难道我做错了什么?我是否还需要在其他地方定义bigTestStyle?希望你们中的一个人之前已经做过这件事,并且知道可能会遗漏什么。感谢。

As you can see the big text message text is not displaying

我的代码:

    NotificationCompat.BigTextStyle bigTextStyle = new NotificationCompat.BigTextStyle();
    bigTextStyle.bigText(extras.getString("message"));
    NotificationCompat.Builder bigTextNotification = new NotificationCompat.Builder(context)
            .setContentTitle("My App")
            .setContentIntent(pendingIntent)
            .setContentText("Message:")
            .setSound(soundUri)
            .setTicker(extras.getString("message"))
            .setWhen(System.currentTimeMillis())
            .setSmallIcon(R.drawable.splash)
            .setAutoCancel(true)
            .setVibrate(new long[] { 0, 100, 200, 300 })
            .setStyle(bigTextStyle);
    final int notificationId = (int) (System.currentTimeMillis() / 1000L);
    NotificationManager thisone = (NotificationManager) getApplicationContext()
            .getSystemService(Context.NOTIFICATION_SERVICE);

    thisone.notify(notificationId, bigTextNotification.build());

来自NotificationCompat.BigTextStyle文档:

  

Helper类,用于生成包含大量文本的大格式通知。   如果平台未提供大幅面通知,则此方法无效。用户将始终看到正常的通知视图。

也许您的平台不支持大幅面通知。

编辑:

另一方面,你的问题可能就在这里:

NotificationCompat.BigTextStyle bigTextStyle = new NotificationCompat.BigTextStyle();
bigTextStyle.bigText(extras.getString("message"));

您没有使用bigText的返回值。

尝试将其更改为:

NotificationCompat.BigTextStyle bigTextStyle = new NotificationCompat.BigTextStyle();
bigTextStyle  = bigTextStyle.bigText(extras.getString("message"));

或者:

NotificationCompat.BigTextStyle bigTextStyle = new NotificationCompat.BigTextStyle().bigText(extras.getString("message"));

EDIT2:

旧版Android版的Costom通知布局:

protected void onMessage(Context context, Intent intent) {
    // Extract the payload from the message
    Bundle extras = intent.getExtras();
    if (extras != null) {
        String message = (String) extras.get("message");
        String title = (String) extras.get("title");                

        // add a notification to status bar
        NotificationManager mManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        Intent myIntent = new Intent(this,MyActivity.class);
        Notification notification = new Notification(R.drawable.notification_image, title, System.currentTimeMillis());
        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
        contentView.setImageViewResource(R.id.image, R.drawable.notification_image);
        contentView.setTextViewText(R.id.title, title);
        contentView.setTextViewText(R.id.text, message);
        notification.contentView = contentView;
        notification.contentIntent = PendingIntent.getActivity(this.getBaseContext(), 0, myIntent, PendingIntent.FLAG_CANCEL_CURRENT);
        mManager.notify(0, notification);
        PowerManager pm = (PowerManager) 
        context.getSystemService(Context.POWER_SERVICE);
        WakeLock wl = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "TAG");
        wl.acquire(15000);
    }
}
