Notification Action not firing PendingIntent

我想創建一個顯示下載進度的通知（它現在被模擬）並允許用戶取消下載。我使用通知生成器並添加「取消下載」操作。該操作會顯示，但不會在點擊時發送PendingIntent。我確認PendingIntent正在通過設置contentIntent來工作。廣播接收器能夠獲取內容點擊的消息，但不能獲得點擊的動作。Notification Action not firing PendingIntent

下載服務

val cancelIntent = Intent(applicationContext, NotificationBroadcastReceiver::class.java).apply { 
    action = "xxx.xxx.xxx.CANCEL_DOWNLOAD" 
    putExtra("notification_id", NOT_ID_PROGRESS) 
} 
val pendingIntent = PendingIntent.getBroadcast(applicationContext, 1, cancelIntent, PendingIntent.FLAG_UPDATE_CURRENT) 

pendingIntent.send() 

val notificationBuilder = NotificationCompat.Builder(applicationContext, "updates").apply { 
    setContentTitle("Title") 
    setContentText("Text") 
    setSmallIcon(R.drawable.ic_logo_full_black) 
    setOnlyAlertOnce(true) 
    setContentIntent(pendingIntent) 
    addAction(NotificationCompat.Action.Builder(R.drawable.ic_delete, "Cancel", pendingIntent).build()) 
} 
startForeground(NOT_ID_PROGRESS, notificationBuilder.build()) 

Thread({ 
    for (i in 0..100) { 
     notificationBuilder.setProgress(100, i, false) 
     notificationManager?.notify(NOT_ID_PROGRESS, notificationBuilder.build()) 
     Thread.sleep(100L) 
    } 
    notificationBuilder.setProgress(0, 0, false) 
    notificationBuilder.setContentText("Download completed") 
    notificationManager?.notify(NOT_ID_COMPLETE, notificationBuilder.build()) 
    onFinish() 
}).start()

NotificationBroadcastReceiver

class NotificationBroadcastReceiver : BroadcastReceiver() { 
    override fun onReceive(context: Context?, intent: Intent?) { 
     val notificationId = intent?.getIntExtra("notification_id", 0) ?: 0 
     Log.d(TAG, "NotificationBroadcastReceiver: notificationId = $notificationId") 
     (context?.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager?)?.cancel(notificationId) 
    } 
}

的AndroidManifest.xml

<service android:name=".services.DownloadService" /> 
<receiver 
    android:name=".services.PackageDownloadService$NotificationBroadcastReceiver" 
    android:enabled="true" 
    android:exported="false"> 
    <intent-filter> 
     <action android:name="xxx.xxx.xxx.CANCEL_DOWNLOAD" /> 
    </intent-filter> 
</receiver>

我自己找到答案。首先，一切都配置正確。我唯一需要改變的是通知的更新間隔。將間隔設置爲大約2000毫秒後，點擊事件在選擇中止操作按鈕時觸發。

Thread({ 
    for (i in 0..100 step 20) { 
     notificationBuilder.setProgress(100, i, false) 
     notificationManager?.notify(NOT_ID_PROGRESS, notificationBuilder.build()) 
     Thread.sleep(2000L) 
    } 
    notificationBuilder.setProgress(0, 0, false) 
    notificationBuilder.setContentText("Download completed") 
    notificationManager?.notify(NOT_ID_COMPLETE, notificationBuilder.build()) 
    onFinish() 
}).start()
