我想创建一个带有进度条和删除按钮的自定义通知。
截图:
我成功创建了带有进度条的自定义通知,但我没有设法创建删除事件。我想取消通知并在用户点击“x”后停止上传(如在谷歌音乐中,因此我不想启动活动来清除通知)。
这是我的工作代码:
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);
在
行Intent notificationIntent = new Intent(context, UploadEventsReceiver.class);
我尝试使用没有“广播”的BroadCast接收器,但我不知道这是否是正确的方法,我没有成功使它工作。我应该使用什么以及如何使用它?

我不确定它是如何在Google音乐中制作的,但您可以为传递给RemoteViews
的布局中的任何视图设置onClickListener。就这样做:
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);
并创建广播,接收CANCEL_BROADCAST_ACTION
并停止您想要的内容,并取消此通知。

另外,我认为(根据文档)您的方法已被弃用。
你应该使用像:
Notification.Builder builder = new Notification.Builder(context);
builder.setContentTitle("Your notification title");
builder.setContentText("Your notification text");
builder.setSmallIcon(R.drawable.ic_your_icon);
builder.setContentIntent(yourIntent);
notificationManager.notify(null, YOUR_UNIQUE_NOTIFICATION_ID, builder.getNotification());
