[英]Handle Push Notification in Kotlin
我正在為我的聊天應用程序使用 Kotlin 導航組件架構,並且我正在使用 Firebase 消息服務來集成推送通知,我的要求是當我在用戶聊天屏幕上時隱藏或禁用通知。請告訴我,我該如何實現這個。 這是我顯示通知的代碼
class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage?) {
Log.d(TAG, "From: ${remoteMessage?.from}")
remoteMessage?.data?.let {
Log.d(TAG, "data payload: " + remoteMessage.data.toString())
val params =remoteMessage.data.get("body")
val objects = JSONObject(params)
Log.e("JSON OBJECT", objects.toString())
val title = remoteMessage.data.get("title").toString()
sendNotification(messageBody,title, applicationContext)
} }
我的通知類是:
fun NotificationManager.sendNotification(messageBody: String, title: String, applicationContext: Context) {
notificationManager = applicationContext.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
// TODO: Step 1.12 create PendingIntent
if(title.equals("Ride Request")) {
fragmentId = R.id.notificationFragment
}
else if(title.equals("Ride Accepted")) {
fragmentId = R.id.inboxFragment
}
else if(title.equals("New Message")) {
fragmentId = R.id.inboxFragment
}
// ---------- creating navgraph intent to open specific fragment ------------
var contentPendingIntent = NavDeepLinkBuilder(applicationContext)
.setComponentName(HomeActivity::class.java)
.setGraph(R.navigation.home_bottom_navigation)
.setDestination(fragmentId)
.setArguments(bundle)
.createPendingIntent()
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
notificationChannel = NotificationChannel(channel_id, description,
NotificationManager.IMPORTANCE_HIGH)
notificationChannel.enableLights(true)
notificationChannel.lightColor = R.color.colorPrimary
notificationChannel.enableVibration(true)
notificationManager.createNotificationChannel(notificationChannel)
builder = NotificationCompat.Builder(applicationContext, channel_id)
.setSmallIcon(R.drawable.icon_car)
.setContentTitle(applicationContext.getString(R.string.app_name))
.setContentText(messageBody)
.setContentIntent(contentPendingIntent)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setAutoCancel(true)
}else {
builder = NotificationCompat.Builder(applicationContext,
applicationContext.getString(R.string.app_name))
.setSmallIcon(R.drawable.icon_car)
.setContentTitle(applicationContext.getString(R.string.app_name))
.setContentText(messageBody)
.setContentIntent(contentPendingIntent)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setAutoCancel(true)
}
notify(NOTIFICATION_ID, builder.build())
}
我不知道這是否完美,但你也可以嘗試一下
如果用戶在聊天屏幕中,您可以創建一個 sharedPref 並將變量的值設置為 true(即用戶在聊天屏幕中)因此在 onMessageReceived() 中檢查 sharedPref 的值是否為 true(這意味着用戶是在聊天屏幕中)如果為真,則不發送通知,如果為假則不發送通知
設置 sharedPref 值 在該聊天活動的 onResume 中設置為 true 在 onPause 中設置為 false
嘗試這個
class InboxFragment : Fragment() {
companion object {
var userId: String? = null
}
override fun onStart() {
userId = navArgs.userId
}
override fun onStop() {
userId = null
}
}
class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage) {
...
if (InboxFragment.userId != remoteMessage.data.get("userId"))
sendNotification(messageBody, title, applicationContext)
}
}
