我使用导航组件。我的应用程序有两个主要部分:1 次飞溅活动,nav_graph2 具有底部导航的主要活动,其中每个菜单项都有自己的nav_graph。问题是当弹出通知时,我无法弄清楚如何进行导航。
因此,当通知到达并且用户单击它时,我需要:- 检查应用程序是否打开以及现在打开的屏幕- 如果应用程序已关闭或在后台,通过深层链接,在启动活动时检查:如果用户已登录 - 移动到主活动(如果未提供身份验证屏幕(保持导航深层链接到我需要的片段。
启动图和三个 memu 项目图之一

您可以使用挂起的意图来执行此操作,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"
}
}
}
根据通知类型,您必须打开特定屏幕,然后您可以执行以下操作:
sendNotification("msg","title",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())
}
在启动画面中,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()
}
如果要传递,也可以传递参数。
在这种情况下,这是一种简单的方法。如果你卡在任何地方,请告诉我。享受。。!!
