问题描述

我想创建一个进度条和一个删除按钮自定义通知。

I want to create a custom notification with a progress bar and a delete button.

截图：

我成功创建了进度条的自定义通知，但我没能创建删除事件。我想取消的通知，并停止上传，一旦用户点击X（如谷歌音乐，所以我不希望启动的活性，清除通知）。

I succeed to create a custom notification with a progress bar, but I did not manage to create the delete event. I want to cancel the notification and stop the upload once the user click on the "x" (as in google music, so i don't want to start an activity to clear the notification).

这是我的工作code：

Here is my working code :

    notificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);

    int icon = R.drawable.ic_launcher;
    CharSequence tickerText = "Hello";
    long when = System.currentTimeMillis();

    notification = new Notification(icon, tickerText, when);    


    CharSequence contentTitle = "My notification";
    CharSequence contentText = "Hello World!";
    Intent notificationIntent = new Intent(context, UploadEventsReceiver.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

    notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
    notification.contentView = new RemoteViews(context.getPackageName(), R.layout.upload_progress);
    notification.contentView.setOnClickPendingIntent(R.id.text, contentIntent);

    notificationManager.notify(this.notificationId, notification);

目前该行

Intent notificationIntent = new Intent(context, UploadEventsReceiver.class);

我试图用广播接收器没有广播，但我不知道这是否是正确的方式来做到这一点，我没有成功，使其工作。我应该怎么使用，如何使用它？

I tried with a BroadCast receiver without "broadcasting" but I don't know if it's the right way to do it and I didn't succeed to make it work. What should I use and how to use it ?

推荐答案

我不知道它是如何制成的谷歌音乐，但你可以设置onClickListener在布局传递给 RemoteViews 。只是这样做：

I'm not sure how it's made in google music, but you can set onClickListener for any view in layout that passed to RemoteViews. Just do like this:

RemoteViews remoteViews = new RemoteViews(widgetPackage, R.layout.widget);
Intent action = new Intent(context, Your_cancel_broadcast.class);
action.setAction(CANCEL_BROADCAST_ACTION);
actionPendingIntent = PendingIntent.getBroadcast(context, 0, action, 0);
remoteViews.setOnClickPendingIntent(R.id.your_x_btn, actionPendingIntent);

和创建广播，接收 CANCEL_BROADCAST_ACTION 和停止你想要什么，并取消该通知。

and create broadcast, that receives CANCEL_BROADCAST_ACTION and stops what you want, and cancel this notification.
