android - 在android中单击通知时如何打开应用程序?
问题描述
我已经在没有意图的情况下向 MainActivity 发出了通知,它工作正常,但是当我将该意图添加到 MainActivity 时,通知不再显示。我的代码有什么问题,还是我需要更改清单或在我的 MainActivity 中添加一些代码?
这是我的代码。我将它设置为两个功能 -setDailyReminder
和showAlarmNotification
.
fun setDailyReminder(context: Context, type: String, message: String) {
val alarmManager = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager
val intent = Intent(context, MainActivity::class.java)
intent.putExtra(EXTRA_MESSAGE, message)
intent.putExtra(EXTRA_TYPE, type)
val timeArray =
TIME_DAILY.split(":".toRegex()).dropLastWhile { it.isEmpty() }.toTypedArray()
val calendar = Calendar.getInstance()
calendar.set(Calendar.HOUR_OF_DAY, Integer.parseInt(timeArray[0]))
calendar.set(Calendar.MINUTE, Integer.parseInt(timeArray[1]))
calendar.set(Calendar.SECOND, 0)
val pendingIntent = PendingIntent.getBroadcast(context,
ID_DAILY, intent, 0)
alarmManager.setInexactRepeating(
AlarmManager.RTC_WAKEUP,
calendar.timeInMillis,
AlarmManager.INTERVAL_DAY,
pendingIntent
)
Toast.makeText(context, "Daily reminder set up", Toast.LENGTH_SHORT).show()
}
private fun showAlarmNotification(
context: Context,
title: String,
message: String?,
notifId: Int
) {
val CHANNEL_ID = "Github App"
val CHANNEL_NAME = "Let's find favourite user on Github"
val notificationManagerCompat =
context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val builder = NotificationCompat.Builder(context, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_play_circle_filled_white_24dp)
.setContentTitle(title)
.setContentText(message)
.setSound(alarmSound)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channel = NotificationChannel(
CHANNEL_ID,
CHANNEL_NAME,
NotificationManager.IMPORTANCE_DEFAULT
)
builder.setChannelId(CHANNEL_ID)
notificationManagerCompat.createNotificationChannel(channel)
}
val notification = builder.build()
notification.flags = notification.flags or Notification.FLAG_AUTO_CANCEL
notificationManagerCompat.notify(notifId, notification)
}
解决方案
fun showNotification(context: Context,title: String, message:String, notifId: Int){
createNotificationChannel(context)
val intent = Intent(context, MainActivity::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
val pendingIntent = PendingIntent.getActivity(this, 0,
intent,PendingIntent.FLAG_ONE_SHOT)
var builder = NotificationCompat.Builder(context, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_play_circle_filled_white_24dp)
.setContentTitle(title)
.setContentText(message)
.setAutoCancel(true)
.setColor(resources.getColor(R.color.colorAccent))
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setContentIntent(pendingIntent)
val notificationManagerCompat = NotificationManagerCompat.from(this)
notificationManagerCompat.notify(notifId, builder.build())
}
private fun createNotificationChannel(context: Context) {
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val name = "Test"
val descriptionText = "FCM"
val importance = NotificationManager.IMPORTANCE_DEFAULT
val channel = NotificationChannel(CHANNEL_ID, name, importance).apply {
description = descriptionText
}
// Register the channel with the system
val notificationManager: NotificationManager =
context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.createNotificationChannel(channel)
}
}
