1.Play/Pause button does not respond to clicks.
2.Clicking the notification does not open the activity.
3.Swipe gesture triggers also… nothing
我不知道我错过了什么。你可以看看我的课程。正在讨论的代码:
private void showMediaStyleNotification() {
// Given a media session and its context (usually the component containing the session)
// Create a NotificationCompat.Builder
// Get the session's metadata
MediaControllerCompat controller = session.getController();
MediaMetadataCompat mediaMetadata = controller.getMetadata();
MediaDescriptionCompat description = mediaMetadata.getDescription();
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
// Add the metadata for the currently playing track
builder
.setContentTitle(description.getTitle())
.setContentText(description.getSubtitle())
.setSubText(description.getDescription())
.setLargeIcon(description.getIconBitmap())
// Enable launching the player by clicking the notification
.setContentIntent(controller.getSessionActivity())
// Stop the service when the notification is swiped away
.setDeleteIntent(MediaButtonReceiver.buildMediaButtonPendingIntent(this,
PlaybackStateCompat.ACTION_STOP))
// Make the transport controls visible on the lockscreen
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
// Add an app icon and set its accent color
// Be careful about the color
.setSmallIcon(R.drawable.ic_headset_pink_40dp)
.setColor(ContextCompat.getColor(this, R.color.secondaryColor))
// Add a pause button
.addAction(new NotificationCompat.Action(
R.drawable.ic_pause_white_40dp, getString(R.string.pause_label),
MediaButtonReceiver.buildMediaButtonPendingIntent(this,
PlaybackStateCompat.ACTION_PLAY_PAUSE)))
// Take advantage of MediaStyle features
.setStyle(new MediaStyle()
.setMediaSession(session.getSessionToken())
.setShowActionsInCompactView(0)
// Add a cancel button
.setShowCancelButton(true)
.setCancelButtonIntent(MediaButtonReceiver.buildMediaButtonPendingIntent(this,
PlaybackStateCompat.ACTION_STOP)));
// Display the notification and place the service in the foreground
startForeground(FOREGROUND_ID, builder.build());
}
}
初始化分离:
stateBuilder = new PlaybackStateCompat.Builder()
.setActions(PlaybackStateCompat.ACTION_PLAY |
PlaybackStateCompat.ACTION_PLAY_PAUSE);
session.setPlaybackState(stateBuilder.build());
当我按play/pause时,它进入这里:GetPlayBackstate fromPlayerState。唯一的问题是播放/暂停按钮图形没有更新。它总是显示暂停
case STARTED:
return stateBuilder.setState(PlaybackStateCompat.STATE_PLAYING, currentPosition, playbackSpeed)
.setActions(PlaybackStateCompat.ACTION_PAUSE | PlaybackStateCompat.ACTION_PLAY_PAUSE
| PlaybackStateCompat.ACTION_STOP | PlaybackStateCompat.ACTION_SEEK_TO
| PlaybackStateCompat.ACTION_PLAY)
.build();
case PAUSED:
return stateBuilder.setState(PlaybackStateCompat.STATE_PAUSED, currentPosition, playbackSpeed)
.setActions(PlaybackStateCompat.ACTION_PLAY | PlaybackStateCompat.ACTION_PLAY_PAUSE
| PlaybackStateCompat.ACTION_STOP | PlaybackStateCompat.ACTION_SEEK_TO
| PlaybackStateCompat.ACTION_PAUSE)
.build();
快速查看一下,您的类似乎没有遵循与相同的布局。还有一个解释如何从通知中打开意图的方法。你是对的@WoodyDev,它没有遵循你建议的布局。但我相信它确实遵循了官方文档->中的布局。您在最新版本的代码中尝试过这个吗?通知中的播放/暂停按钮对我来说工作正常-在安卓5.1手机上测试。[在安卓8.0上,由于某种原因,通知不会出现]我想您可能在使用主屏幕小部件时已经修复了它。就未决的意图处理而言,它们共享大部分相同的框架,这很好。
