我要更改通知smallIcon
在前台服务运行时的状态栏中,取决于服务收集的状态,即“静音”或“取消静音”。
显示备用 smallIcons
需要什么来自 res.drawable
资源?
在服务类的initialize方法中,我目前设置静音图标如下,但是不知道服务启动后怎么改:
NotificationCompat.Builder builder = new NotificationCompat.Builder(
this, NOTE_CHANNEL_ID)
.setSmallIcon(R.drawable.mute_icon)
.setContentTitle("Calm: Running")
.setContentText(this.getString(R.string.calm_close_txt))
.setOngoing(true)
.setContentIntent(stopIntent);
startForeground(NOTIFICATION_ID, builder.build());
最佳答案
解决方法是创建一个带有新图标的新通知,这样它就会替换旧的。
编辑:
这是一个示例代码,用于在每次单击按钮时创建一个新通知,其中包含基于 bool 变量 indicator
的示例逻辑。 .
findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Create the notification builder object
NotificationCompat.Builder builder = new NotificationCompat.Builder(v.getContext(), NOTE_CHANNEL_ID)
.setSmallIcon(indicator ? R.drawable.icon1 : R.drawable.icon2) //TODO: change this line with your logic
.setContentTitle("Your notification title here")
.setContentText("Your notificiation text here")
.setPriority(NotificationCompat.PRIORITY_HIGH)
// .setContentIntent(pendingIntent) //pendingIntent to fire when the user taps on it
.setAutoCancel(true); //autoremove the notificatin when the user taps on it
//show the notification constructed above
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(v.getContext());
notificationManager.notify(NOTIFICATION_ID, builder.build());
indicator = !indicator; //switch icon indicator (just for demonstration)
}
});
