Question

我使用以下代码添加通知，并在通知中添加两个功能，一个是声音，另一个是闪烁灯。

String ns = Context.NOTIFICATION_SERVICE;
                NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
                int icon = R.drawable.icon;
                CharSequence tickerText = "Hello";
                long when = System.currentTimeMillis();
                Notification notification = new Notification(icon, tickerText, when);
                RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.cutomnotification);
                contentView.setTextViewText(R.id.textView1,"Custom");
                notification.contentView = contentView;
                Intent notificationIntent = new Intent(v.getContext(), MyClass.class);
                PendingIntent contentIntent = PendingIntent.getActivity(v.getContext(), 0, notificationIntent, 0);
                notification.contentIntent = contentIntent;
                notification.sound=android.provider.Settings.System.DEFAULT_RINGTONE_URI;
                notification.ledARGB = 0xff00ff00;
                notification.ledOnMS = 300;
                notification.ledOffMS = 1000;
                notification.flags=Notification.FLAG_INSISTENT|Notification.FLAG_SHOW_LIGHTS|Notification.FLAG_NO_CLEAR;
                mNotificationManager.notify(HELLO_ID, notification);

在这里我也使用自定义布局

现在我有两个问题，

1）当用户点击通知标签时，声音会播放并停止播放，但我想继续播放声音，直到用户按下自定义布局上的任意按钮。

2）我在自定义布局中添加了一个按钮，现在我可以在其上实现onClickListener（）。

Answer 1

在notification.contentIntent = contentIntent;

之后添加此代码

notification.flags |= Notification.FLAG_NO_CLEAR; //Do not clear the notification
notification.defaults |= Notification.DEFAULT_LIGHTS; // LED
notification.defaults |= Notification.DEFAULT_VIBRATE; //Vibration
notification.defaults |= Notification.DEFAULT_SOUND;

您可以在不使用 setSound（）的情况下创建 NotificationCompat.Builder 对象。这将创建一个没有任何声音的通知。

 notification = mBuilder    
            .setStyle(notiStyle)   
            .setSmallIcon(notificationIcon)  
            .setTicker(title)  
            .setWhen(0)  
            .setAutoCancel(true)  
            .setContentTitle(title)  
            .setContentIntent(resultPendingIntent)  
            .build();

通知声音停止点击
