从通知栏的GCM通知消息将不会在活动中显示,如果该应用程序尚未启动 [英] The GCM Notification message from the Notification Bar will not be shown in the activity if the app isn't started already
问题描述
我使用本教程推送通知<一个href=\"http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/\" rel=\"nofollow\">http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/
它工作正常,但是当我在状态栏上点击查看收到的消息,它不会在它开始在MainActivity显示。问题是什么?

I am using this tutorial for push notifications http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/

Update the TextView after you initialize it
lblMessage = (TextView) findViewById(R.id.lblMessage);
As you are making notification and putting the value with the key "message", so you need to retrieve the value though the same key "message"
lblMessage.append("New Message: "+ i.getStringExtra("message") + "\n");
这篇关于从通知栏的GCM通知消息将不会在活动中显示,如果该应用程序尚未启动的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
