android - 关闭应用程序时单击 Firebase 通知后打开特定 Activity/fragment

Question

我知道这个问题似乎重复，但根据我的要求，我在网上搜索了很多帖子，但没有一个对我有用。

我的要求

我正在使用 Firebase 获取推送通知。当应用程序打开时意味着一切正常，但我的问题是，如果有任何推送通知出现，应用程序处于后台/关闭意味着我想在单击该通知时打开特定的 Activity 或 fragment ，但它总是打开启动器/主要 Activity 。

为此，我尝试了以下场景

场景 1

使用 bundle 将通知数据从 FirebaseMessagingService 传输到启动器/主 Activity ，并根据我重定向到特定 Activity/fragment 的 bundle 数据

场景 2

通过使用Sharedpreference

场景 3

通过使用 intent.putExtra

按照上述情况，当应用程序打开时一切正常，但如果我的应用程序关闭意味着它总是重定向到主/启动器 Activity

我的代码

    Intent intent = new Intent(this, MainActivity.class);
    intent.putExtra("reqTo", messageBody);

    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(title)
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

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

    notificationManager.notify(0, notificationBuilder.build());

那么，有没有人知道如何在关闭应用程序时单击 Firebase 推送通知来打开特定的 Activity/fragment 。

Answer 1

public void showNotificationMessage(final String title, final String message, Intent intent) {
    // Check for empty push message
    if (TextUtils.isEmpty(message))
        return;


// notification icon
final int icon = R.drawable.logo;

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
final PendingIntent resultPendingIntent =
        PendingIntent.getActivity(
                mContext,
                0,
                intent,
                PendingIntent.FLAG_CANCEL_CURRENT
        );

final NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
        mContext);

final Uri alarmSound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE
        + "://" + mContext.getPackageName() + "/raw/notification");


    showSmallNotification(mBuilder, icon, title, message, resultPendingIntent, alarmSound);
    playNotificationSound();

}



private void showSmallNotification(NotificationCompat.Builder mBuilder, int icon, String title, String message, PendingIntent resultPendingIntent, Uri alarmSound) {

            NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();

            inboxStyle.addLine(message);

            Notification notification;
            notification = mBuilder.setSmallIcon(icon).setTicker(title).setWhen(0)
                    .setAutoCancel(true)
                    .setContentTitle(title)
                    .setContentIntent(resultPendingIntent)
                    .setSound(alarmSound)
                    .setStyle(inboxStyle)
                    .setSmallIcon(R.drawable.logo)
                    .setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
                    .setContentText(message)
                    .build();

            NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManager.notify(Config.NOTIFICATION_ID, notification);
        }


private void showBigNotification(Bitmap bitmap, NotificationCompat.Builder mBuilder, int icon, String title, String message, PendingIntent resultPendingIntent, Uri alarmSound) {
        NotificationCompat.BigPictureStyle bigPictureStyle = new NotificationCompat.BigPictureStyle();
        bigPictureStyle.setBigContentTitle(title);
        bigPictureStyle.setSummaryText(Html.fromHtml(message).toString());
        bigPictureStyle.bigPicture(bitmap);
        Notification notification;
        notification = mBuilder.setSmallIcon(icon).setTicker(title).setWhen(0)
                .setAutoCancel(true)
                .setContentTitle(title)
                .setContentIntent(resultPendingIntent)
                .setSound(alarmSound)
                .setStyle(bigPictureStyle)
                .setSmallIcon(R.drawable.logo)
                .setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
                .setContentText(message)
                .build();

        NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(Config.NOTIFICATION_ID_BIG_IMAGE, notification);
    }

你可以像这样检查应用是否关闭

if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
