我的应用通过通知媒体控制器（ PLAY 和 PAUSE ）操作播放音乐，下面的代码显示了PLAY和PAUSE两个操作，我如何制作一个{{1 }}暂停播放音乐，而不是两个。
button我想在用户单击时用一个按钮（ PLAY ）显示通知，然后转到（PAUSE）（类似于 public void createNotification(Context context, String all, String channelId, NotificationManager notificationManager) {
Intent yesReceive = new Intent(NOTIFICATION_SERVICE);
yesReceive.setAction(MyIntentSerice.RESUME_ACTION);
PendingIntent pendingIntentYes = PendingIntent.getBroadcast(this, MyIntentSerice.REQUEST_CODE_NOTIFICATION, yesReceive, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Action actionplay = new NotificationCompat.Action.Builder(R.drawable.playicon, "Play", pendingIntentYes).build();
Intent yesReceive2 = new Intent(NOTIFICATION_SERVICE);
yesReceive2.setAction(MyIntentSerice.STOP_ACTION);
PendingIntent pendingIntentYes2 = PendingIntent.getBroadcast(this, MyIntentSerice.REQUEST_CODE_NOTIFICATION, yesReceive2, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Action actionpause = new NotificationCompat.Action.Builder(R.drawable.pauseicon, "Pause", pendingIntentYes2).build();
NotificationCompat.Builder b = new NotificationCompat.Builder(context, channelId);
Intent myIntent = new Intent(context, MainActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP |
Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
myIntent, 0);
b.setAutoCancel(false);
b.setDefaults(Notification.DEFAULT_ALL);
b.setWhen(System.currentTimeMillis());
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.icon2);
b.setContentTitle(title);
b.setContentText(artist);
b.setContentIntent(contentIntent);
b.setDefaults(Notification.DEFAULT_LIGHTS);
b.setPriority(Notification.PRIORITY_MAX);
b.setShowWhen(true);
b.setColor(ContextCompat.getColor(context, R.color.khdar));
b.addAction(actionpause);
b.addAction(actionplay);
notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
assert notificationManager != null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
"app name", NotificationManager.IMPORTANCE_LOW);
notificationManager.createNotificationChannel(channel);
channel.setDescription("no sound");
channel.setSound(null, null);
channel.enableLights(false);
channel.setLightColor(Color.RED);
channel.enableVibration(false);
}
if (Build.VERSION.SDK_INT < 16) {
notificationManager.notify(1, b.getNotification());
} else
notificationManager.notify(1, b.build());
}
