[android : kotlin] 코틀린 Notification MediaStyle 사용시 SeekBar 설정 및 해제 하는 방법
위에서 보는 이미지에서 처럼 미디어 스타일의 알림을 노출할 때 노래 재생이 어디까지 진행되고 있는지 확인하기 위해 SeekBar를 사용할 수 있다.
SeekBar를 숨기거나 노출하는 방법에 대해 알아보자
아래 코드 스니펫을 살펴보면 setStyle메서드 안에서 setMediaSession()메서드를 명시하면 SeekBar가 노출 된다. 명시하지 않으면 노출되지않는다.
[SeekBar 노출하기]
// 미디어 스타일 적용하기
setStyle(
androidx.media.app.NotificationCompat.MediaStyle()
.setMediaSession(sessionToken)
.setShowActionsInCompactView(0, 1, 2)
// Add a cancel button
.setShowCancelButton(true)
.setCancelButtonIntent(
MediaButtonReceiver.buildMediaButtonPendingIntent(
applicationContext, PlaybackStateCompat.ACTION_STOP
)
)
)
[SeekBar 감추기]
// 미디어 스타일 적용하기
setStyle(
androidx.media.app.NotificationCompat.MediaStyle()
//.setMediaSession(sessionToken)
.setShowActionsInCompactView(0, 1, 2)
// Add a cancel button
.setShowCancelButton(true)
.setCancelButtonIntent(
MediaButtonReceiver.buildMediaButtonPendingIntent(
applicationContext, PlaybackStateCompat.ACTION_STOP
)
)
)
NotificationCompat.Builder 전체코드는 다음과 같다.
private fun getNotification(playbackState: Int) : NotificationCompat.Builder {
// Get the session's metadata
val controller = mediaSession.controller
val mediaMetadata = controller.metadata
val description = mediaMetadata.description
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val builder = NotificationCompat.Builder(this, CHANNEL_ID).apply {
setContentTitle(description.title)
setContentText(description.subtitle)
setSubText(description.description)
setLargeIcon(description.iconBitmap) // 반드시 bitmap호출
// Show controls on lock screen even when user hides sensitive content.
setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
// Enable launching the player by clicking the notification
setContentIntent(controller.sessionActivity)
setSmallIcon(R.mipmap.ic_launcher_round)
setShowWhen(false)
priority = NotificationCompat.PRIORITY_HIGH
//setOnlyAlertOnce(true)
//setChannelId(CHANNEL_ID)
setDeleteIntent(
MediaButtonReceiver.buildMediaButtonPendingIntent(
applicationContext,
PlaybackStateCompat.ACTION_STOP
)
)
addAction(
R.drawable.baseline_skip_previous_24,
getString(R.string.previous),
MediaButtonReceiver.buildMediaButtonPendingIntent(
applicationContext,
PlaybackStateCompat.ACTION_SKIP_TO_PREVIOUS
)
).build()
// Add a pause button
if(playbackState == PlaybackStateCompat.STATE_PLAYING) {
addAction(
NotificationCompat.Action(
R.drawable.baseline_pause_circle_outline_24,
getString(R.string.pause),
MediaButtonReceiver.buildMediaButtonPendingIntent(
applicationContext,
PlaybackStateCompat.ACTION_PLAY_PAUSE
)
)
)
}else{
addAction(
R.drawable.baseline_play_circle_outline_24,
getString(R.string.play),
MediaButtonReceiver.buildMediaButtonPendingIntent(
applicationContext,
PlaybackStateCompat.ACTION_PLAY_PAUSE
)
).build()
}
addAction(
R.drawable.baseline_skip_next_24,
getString(R.string.next),
MediaButtonReceiver.buildMediaButtonPendingIntent(
applicationContext,
PlaybackStateCompat.ACTION_SKIP_TO_NEXT
)
).build()
// Take advantage of MediaStyle features
setStyle(
androidx.media.app.NotificationCompat.MediaStyle()
.setMediaSession(sessionToken)
.setShowActionsInCompactView(0, 1, 2)
// Add a cancel button
.setShowCancelButton(true)
.setCancelButtonIntent(
MediaButtonReceiver.buildMediaButtonPendingIntent(
applicationContext, PlaybackStateCompat.ACTION_STOP
)
)
)
}
return builder
}
return NotificationCompat.Builder(this, CHANNEL_ID)
