Android Kotlin Timer 是一个使用 Kotlin 编写的计时器应用程序,它可以用于计时器、倒计时器等。
private fun startTimer() {
timerStarted = true
timerTask = object : TimerTask() {
override fun run() {
runOnUiThread {
timerSeconds++
updateTimer()
}
}
}
timer.schedule(timerTask, 1000, 1000)
}
private fun stopTimer() {
timerStarted = false
timerTask?.cancel()
}
private fun resetTimer() {
timerStarted = false
timerSeconds = 0
timerTask?.cancel()
updateTimer()
}
private fun recordTime() {
records.add(timerSeconds)
}
private fun startForegroundService() {
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channel = NotificationChannel(
"timer_channel",
"Timer Foreground Service",
NotificationManager.IMPORTANCE_DEFAULT
)
notificationManager.createNotificationChannel(channel)
}
val notificationBuilder = NotificationCompat.Builder(this, "timer_channel")
.setContentTitle("Timer is running")
.setContentText("The timer is running in the background")
.setSmallIcon(R.drawable.ic_timer)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
startForeground(TIMER_NOTIFICATION_ID, notificationBuilder.build())
}
Android Kotlin Timer 是一个简单实用的计时器应用程序,有着丰富的功能和易用的代码。如果您希望使用 Kotlin 编写自己的计时器应用,可以参考本程序的代码实现。
