Java 媒体样式通知操作按钮不适用于PendingEvent.getBroadcast()
我正在使用Java 媒体样式通知操作按钮不适用于PendingEvent.getBroadcast(),java,android,notifications,android-notifications,android-notification.mediastyle,Java,Android,Notifications,Android Notifications,Android Notification.mediastyle,我正在使用NotificationCompat.MediaStyle()创建具有通知风格的音乐播放器 我实现了在通知中单击操作按钮时发送广播的代码。但我的代码似乎不起作用 以下是我的代码: NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this) .setShowWhen(false)

创建具有通知风格的音乐播放器
我实现了在通知中单击操作按钮时发送广播的代码。但我的代码似乎不起作用
以下是我的代码:
NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setShowWhen(false)
// Set the Notification style
.setStyle(new NotificationCompat.MediaStyle()
// Attach our MediaSession token
.setMediaSession(mediaSession.getSessionToken())
// Show our playback controls in the compact notification view.
.setShowActionsInCompactView(0, 1, 2))
// Set the Notification color
.setColor(getResources().getColor(R.color.colorPrimary))
// Set the large and small icons
.setLargeIcon(largeIcon)
.setSmallIcon(android.R.drawable.stat_sys_headset)
// Set Notification content information
.setContentText("Artist Name")
.setContentTitle("Album name")
.setContentInfo("Title name")
// Add playback actions
.addAction(android.R.drawable.ic_media_previous, "previous", playbackAction(3))
.addAction(notificationAction, "pause", play_pauseAction)
.addAction(android.R.drawable.ic_media_next, "next", playbackAction(2));
((NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE)).notify(NOTIFICATION_ID, notificationBuilder.build());
BroadcastReceiver broadCastPlayback=new BroadcastReceiver(){
@Override
public void onReceive(Context context, Intent intent)
{
// TODO: Implement this method
showToast("onReceive");
}
};
方法playBackAction()
如下所示:
private PendingIntent playbackAction(int actionNumber){
Intent playbackAction;
switch(actionNumber){
case 0:
// Play
playbackAction = new Intent(BROADCAST_PLAYBACK);
playbackAction.setAction(ACTION_PLAY);
return PendingIntent.getBroadcast(this, actionNumber, playbackAction, 0);
case 1:
// Pause
playbackAction = new Intent(BROADCAST_PLAYBACK);
playbackAction.setAction(ACTION_PAUSE);
return PendingIntent.getBroadcast(this, actionNumber, playbackAction, 0);
case 2:
// Next track
playbackAction = new Intent(BROADCAST_PLAYBACK);
playbackAction.setAction(ACTION_NEXT);
return PendingIntent.getService(this, actionNumber, playbackAction, 0);
case 3:
// Previous track
playbackAction = new Intent(BROADCAST_PLAYBACK);
playbackAction.setAction(ACTION_PREVIOUS);
return PendingIntent.getBroadcast(this, actionNumber, playbackAction, 0);
default:
break;
}
return null;
}
我的收信人如下:
NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setShowWhen(false)
// Set the Notification style
.setStyle(new NotificationCompat.MediaStyle()
// Attach our MediaSession token
.setMediaSession(mediaSession.getSessionToken())
// Show our playback controls in the compact notification view.
.setShowActionsInCompactView(0, 1, 2))
// Set the Notification color
.setColor(getResources().getColor(R.color.colorPrimary))
// Set the large and small icons
.setLargeIcon(largeIcon)
.setSmallIcon(android.R.drawable.stat_sys_headset)
// Set Notification content information
.setContentText("Artist Name")
.setContentTitle("Album name")
.setContentInfo("Title name")
// Add playback actions
.addAction(android.R.drawable.ic_media_previous, "previous", playbackAction(3))
.addAction(notificationAction, "pause", play_pauseAction)
.addAction(android.R.drawable.ic_media_next, "next", playbackAction(2));
((NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE)).notify(NOTIFICATION_ID, notificationBuilder.build());
BroadcastReceiver broadCastPlayback=new BroadcastReceiver(){
@Override
public void onReceive(Context context, Intent intent)
{
// TODO: Implement this method
showToast("onReceive");
}
};
我在安卓服务的onCreate
中注册了广播接收器
IntentFilter filter=new IntentFilter(BROADCAST_PLAYBACK);
registerReceiver(broadCastPlayback,filter);
未调用
onReceive
中的showtoos()
方法。我想知道广播是未发送还是未接收 您遇到的问题是筛选器缺少在挂起意图中发送的操作
例如:.addAction(android.R.drawable.ic\u media\u previous,“previous”,playbackAction(3))
将发送动作动作\u previous
但boradcast接收器仅在播放时过滤
在筛选器中,您需要添加(或替换为)缺少的操作
举个例子:
filter.addAction(ACTION_PREVIOUS);
以同样的方式添加您定义的其他操作。检查此答案,它可能会对您有所帮助
