收到多个Android通知时,只有最新的通知上的操作按钮有效

问题描述 投票:0回答:1

我的Android通知有操作按钮。当我连续发送两个通知时,点击第一个上的操作按钮没有任何效果(操作处理程序代码将不会执行),但点击最近通知上的操作按钮可以按预期工作。

private void displayNotification(Context context, ChallengeInformation extras) {
    /* build the notification */
    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(context)
                    .setSmallIcon(R.drawable.status_bar_icon)
                    .setContentTitle(context.getString(R.string.push_notification_title))
                    .setStyle(new NotificationCompat.BigTextStyle()
                            .bigText(getChallengeContextString(extras)))
                    .setContentText(context.getString(R.string.push_notification_description))
                    .setAutoCancel(false) // We don't want to cancel when the user clicks
                    .setPriority(NotificationCompat.PRIORITY_MAX)
                    .setColor(context.getResources().getColor(R.color.notification))
                    .setLocalOnly(true) // we handle notifications on Wear separately
                    .setDefaults(DEFAULTS);

    /* set the target of the notification */
    PendingIntent challenge =
            getChallengePendingIntent(context, extras);
    mBuilder.setContentIntent(challenge);

    addNotificationActions(mBuilder, context, extras);

    challengeTracker.notifyChallenge(extras, context, mBuilder.build());
}

private void addNotificationActions(NotificationCompat.Builder builder, Context context,
                                    ChallengeInformation extras) {
    //add buttons to the notification
    PendingIntent approveIntent = getResponsePendingIntent(context, extras, true, ACCEPT_REQUEST_CODE);
    NotificationCompat.Action approveAction =
            new NotificationCompat.Action.Builder(R.drawable.notification_action_approve,
                    context.getString(R.string.notification_approve_text), approveIntent).build();
    NotificationCompat.Action rejectAction =
            new NotificationCompat.Action.Builder(R.drawable.notification_action_decline,
                    context.getString(R.string.notification_reject_text), rejectIntent).build();

    builder.addAction(approveAction);
    builder.addAction(rejectAction);
}

public static PendingIntent getResponsePendingIntent(Context context, ChallengeInformation info,
                                                     boolean approve, int requestCode) {
    Intent cancel = new Intent(context, GcmBroadcastReceiver.class);

    cancel.setAction(Constants.RESPOND_TO_SERVER);
    cancel.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    cancel.putExtras(info.getBundle());
    cancel.putExtra(Constants.USER_RESPONSE_ACCEPTED_KEY, approve);

    return PendingIntent.getBroadcast(context, requestCode, cancel,
            PendingIntent.FLAG_CANCEL_CURRENT);
}

最近的通知不会取消之前的通知,这是我们想要的。但是,最近的一个似乎是禁用以前通知中的操作按钮。

有没有人有想法可能导致它?我一直在玩意图标志,但到目前为止似乎没有任何区别。

提前致谢。

在操作响应待处理意图中,确保请求代码对于每个通知都是唯一的:

PendingIntent.getBroadcast(context, requestCode, cancel, PendingIntent.FLAG_CANCEL_CURRENT);

请注意,此代码中的requestCode必须是唯一编号。如果它与之前的通知操作意图相同,则最终将覆盖前一个通知操作意图。
