[英]Notification is not opening Activity onClick
I have AlarmNotification in my app and everytime it appeared I want to click on it and open parent Activity/wakeup app from background.我的应用程序中有 AlarmNotification,每次出现时我都想单击它并从后台打开父 Activity/wakeup 应用程序。 Why it doesnt work?为什么它不起作用? It will show notification in certain time so alarm part is working as intended, but It will not do any action on click.它会在特定时间显示通知,因此警报部分按预期工作,但它不会在点击时执行任何操作。
First I have to create notification:首先我必须创建通知:
private fun createNotification(){
val vibrateFreq = longArrayOf(1000, 1000, 1000, 1000, 1000)
nb = NotificationCompat.Builder(a, channelId)
.setSmallIcon(R.drawable.logo)
.setContentTitle(title)
.setContentText(text)
.setVibrate(vibrateFreq)
.setStyle(NotificationCompat.BigTextStyle().bigText(textLong))
.setAutoCancel(true)
}
Then I need to register Alarm to show notification in certain time:然后我需要注册警报以在特定时间显示通知:
private fun createAlarm(){
val pInt = app.createAlarmPendingIntent(a, nb)
val cal = Calendar.getInstance()
cal.add(Calendar.MINUTE, delta)
app.aManager.set(AlarmManager.RTC_WAKEUP, cal.timeInMillis, pInt)
}
fun createAlarmPendingIntent(a: Activity, nb: NotificationCompat.Builder?): PendingIntent{
val nInt = Intent(a, AlarmReceiver::class.java)
nInt.putExtra(
AlarmReceiver.NOTIFICATION_ID,
AlarmNotification.NOTIFICATION_NAME
)
nInt.putExtra(AlarmReceiver.NOTIFICATION, nb?.build())
val pInt = PendingIntent.getBroadcast(
a,
0,
nInt,
PendingIntent.FLAG_UPDATE_CURRENT
)
return pInt
}
Then It will trigger BroadcastReceiver
to open Notification:然后它会触发BroadcastReceiver
打开通知:
class AlarmReceiver: BroadcastReceiver(){
companion object{
const val NOTIFICATION_ID = "20288855447-99899"
const val NOTIFICATION = "alarmNotify"
}
override fun onReceive(context: Context?, intent: Intent?) {
val notificationManager = context?.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val notification: Notification? = intent?.getParcelableExtra(NOTIFICATION)
val id = intent?.getIntExtra(NOTIFICATION_ID, 0)
id?.let {
notificationManager.notify(id, notification)
}
}
}
First you need to declare an Intent like:首先,您需要声明一个 Intent,例如:
Intent notificationClickIntent = new Intent("intent_id")
Then you need to declare a Pending Intent like this:然后你需要像这样声明一个 Pending Intent:
PendingIntent pendingIntent = PendingIntent.getActivity(context, REQUEST_CODE, notificationClickIntent, PendingIntent.FLAG_UPDATE_CURRENT);
In your notification builder add set contentIntent:在您的通知构建器中添加设置 contentIntent:
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle(notificationData.getTitle())
.setContentText(notificationData.getBody())
.setPriority(NotificationCompat.PRIORITY_HIGH)
**.setContentIntent(notificationClickPendingIntent)**
.addAction(R.drawable.ic_notification, context.getString(R.string.turn_on_alarms), notificationButtonClickPendingIntent)
.setAutoCancel(true)
In your manifest declare an intent filter on the activity you want to open (as I remember I could not make it work for the launcher activity, maybe it can work, I just gave up).在您的清单中声明您要打开的活动的意图过滤器(因为我记得我无法使其适用于启动器活动,也许它可以工作,我只是放弃了)。
<activity
android:name="Activity_name"
android:launchMode="singleTask"
android:screenOrientation="portrait"
android:theme="@style/AppTheme.NoActionBar.LightStatusBar">
<intent-filter>
<action android:name="intent_id" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
And last but not least, if activity hasn't been opened, notification onClick will trigger the onCreate method, if it has been opened, it will trigger the onNewIntent最后但同样重要的是,如果activity没有打开,通知onClick会触发onCreate方法,如果它已经打开,会触发onNewIntent
hope this helps:)希望这可以帮助:)
