与闪屏和登录状态的深度链接

Question

我使用导航组件。我的应用程序有 2 个主要部分：1 个带有 nav_graph 的初始活动 2 个带有底部导航的主要活动，其中每个菜单项都有自己的 nav_graph。问题是我无法弄清楚弹出通知时如何进行导航。

因此，当通知到达并且用户点击它时，我需要： - 检查应用程序是否打开以及现在打开哪个屏幕 - 如果应用程序关闭或在后台，通过深层链接，检查启动活动：如果用户已登录 - 移动到主要活动（如果不提供身份验证屏幕）保持导航到我需要的片段的深层链接。

您可以使用挂起的意图来完成此操作，假设您获得如下所示的数据有效负载：

{
      "title":"Title",
      "message":"message test",
      "data":{
             "meta":{
                "notificationType":"1",
                 "name":"Rjz"
                    }
             }
}

根据notificationType，您必须打开特定屏幕，然后您可以执行以下操作：

sendNotification("消息","标题",remoteMessage.data)

private fun sendNotification(messageBody: String,title: String?,data: MutableMap<String, String>) {

    val intent = Intent(this, SplashActivity::class.java)
    intent.putExtra("meta", data["meta"])
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
    val pendingIntent = PendingIntent.getActivity(
        this, 0 /* Request code */, intent,
        PendingIntent.FLAG_ONE_SHOT
    )

    val channelId = getString(R.string.default_notification_channel_id)
    val defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
    val notificationBuilder = NotificationCompat.Builder(this, channelId)

    notificationBuilder.setSmallIcon(R.drawable.ic_app_logo)
        .setContentTitle(title)
        .setContentText(messageBody)
        .setAutoCancel(true)
        .setStyle(NotificationCompat.BigTextStyle())
        .setSound(defaultSoundUri)
        .setContentIntent(pendingIntent)

    val notificationManager =
        getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager

    // Since android Oreo notification channel is needed.
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        val channel = NotificationChannel(
            channelId,
            "Channel human readable title",
            NotificationManager.IMPORTANCE_DEFAULT
        )
        notificationManager.createNotificationChannel(channel)
    }

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build())
}

在启动屏幕中，您可以检查待处理的意图数据，如下所示：

val metaString: String? = if (intent.hasExtra("meta")) {
                intent.extras.get("meta").toString()
            } else {
                null
            }
    var gson = Gson()   
    var pushData = gson.fromJson(
                    metaString,
                    YourModel::class.java
                )       
    if(pushData.notificationType==1){
    NavDeepLinkBuilder(this@SplashActivity)
            .setComponentName(MainActivity::class.java)
            .setGraph(R.navigation.name_of_nav_graph)
            .setDestination(R.id.your_dstination_fragment)
            .setArguments(bundleOf(
                         "name" to pushData.name)
                         ).createTaskStackBuilder().startActivities()
    }

如果你想通过也可以通过参数。

在这种情况下这是一个简单的方法。如果您卡在任何地方，请告诉我。享受..！！
