Question

我的java代码：我正在使用下面的代码，但它不起作用。

    Intent intent = new Intent(context, LiveFeedScreen.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
    final int not_nu = generateRandom();
    PendingIntent pendingIntent = PendingIntent.getActivity(context,
            not_nu, intent, PendingIntent.FLAG_ONE_SHOT);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(
            context)
            .setSmallIcon(R.drawable.notificationbig_icon)
            .setColor(context.getResources().getColor(R.color.header_blue))
            .setContentTitle(context.getString(R.string.app_name))
            .setContentText(mMessage)
            .setAutoCancel(true)
            .setStyle(
                    new NotificationCompat.BigTextStyle().bigText(mMessage))
            .setContentIntent(pendingIntent);
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(not_nu, notificationBuilder.build());

它仅在棒棒糖下面工作但是它的显示非常小。

你可以尝试下面的一个：`private void Notify（String notificationMessage，String pushFullMessage）{

    Intent intent = new Intent(this, GCMNotificationActivity.class);
    intent.putExtra("pushNotification", pushFullMessage);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    final int not_nu = generateRandom();
    PendingIntent pendingIntent = PendingIntent.getActivity(this,
            not_nu, intent, PendingIntent.FLAG_ONE_SHOT);


    android.support.v4.app.NotificationCompat.Builder notificationBuilder = new android.support.v4.app.NotificationCompat.Builder(
            this)
            .setSmallIcon(R.drawable.app_logo) //Small Icon from drawable
            .setContentTitle(this.getString(R.string.app_name))
            .setContentText(notificationMessage)
            .setAutoCancel(true)
            .setLocalOnly(true)
            .setColor(this.getResources().getColor(R.color.green))
            .setStyle(
                    new android.support.v4.app.NotificationCompat.BigTextStyle().bigText(notificationMessage))

// .setLargeIcon（ // BitmapFactory.decodeResource（this.getResources（）， // R.drawable.ic_launcher））//来自drawable的大图标 .setContentIntent（的PendingIntent）;

    notificationBuilder.setPriority(Notification.PRIORITY_HIGH);
    notificationBuilder.setDefaults(Notification.DEFAULT_SOUND);
    notificationBuilder.setVibrate(new long[]{0, 100, 200, 300});

    NotificationManager notificationManager = (NotificationManager) this
            .getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(not_nu, notificationBuilder.build());
}

public static int generateRandom() {
    Random random = new Random();
    return random.nextInt(9999 - 1000) + 1000;
}

`
