Facebook如何在Android中的应用图标上添加徽章数字？

问题描述

我知道这里有几个问题，询问是否可以添加一个Android应用程序的徽章，他们都结束了一个没有答案...

但是不知何故最新的Android版测试版本，即使它在技术上不是这样。

在那篇文章中评论者说这与TouchWiz有些相关。
和提到它作为S3 TouchWiz Jelly Bean Addon的功能。

我仍然非常欣赏有关如何做到这一点的信息，如果有一些API可以在我自己的应用程序中使用（在适当的环境中运行） - 即与FB相同的设备演示了这种行为）？

解决方案

我已经弄清楚这是如何为Sony设备完成的。 / p>

我已经发表了关于。我也发布了一个关于这个。

Sony设备使用一个名为 BadgeReciever 。

1. 声明 com.sonyericsson.home.permission .BROADCAST_BADGE 您的清单文件中的权限：
   




2. 广播到 BadgeReceiver ：

     Intent intent = new Intent ）; 
    
    intent.setAction（com.sonyericsson.home.action.UPDATE_BADGE）; 
    intent.putExtra（com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME，com.yourdomain.yourapp.MainActivity）; 
    intent.putExtra（com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE，true）; 
    intent.putExtra（com.sonyericsson.home.intent.extra.badge.MESSAGE，99）; 
    intent.putExtra（com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME，com.yourdomain.yourapp）; 
    
    sendBroadcast（intent）; 
     




3. 完成。一旦这个 Intent 被广播，启动器应该在您的应用程序图标上显示徽章。




4. 要删除再次发送徽章，只需发送一个新的广播，这次与 SHOW_MESSAGE 设置为false：

     intent.putExtra（com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE，false）; 
     

我已经排除了我如何找到的细节这是为了保持答案简短，但它都可以在博客中。可能是一个有趣的读者。

I know there are several Qs here that ask if its possible to add badges to an android app and they all end up with a NO answer...

But somehow the latest Facebook beta version for Android seems to do something which at least look like a badge even if it is not technically exactly that.

In that post one of the commenters says that it is somehow related to TouchWiz.And also here they mention it as a feature of the "S3 TouchWiz Jelly Bean Addon".

I still would appreciate information on how does this can be done and if there is some API for this that I can use in my own app (when running in an appropriate environment - i.e. the same device where FB demonstrates this behavior) ?

解决方案

I have figured out how this is done for Sony devices.

I've blogged about it here. I've also posted a seperate SO question about this here.

Sony devices use a class named BadgeReciever.

1. Declare the com.sonyericsson.home.permission.BROADCAST_BADGE permission in your manifest file:

2. Broadcast an Intent to the BadgeReceiver:

   Intent intent = new Intent();
   
   intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", "com.yourdomain.yourapp.MainActivity");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "99");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", "com.yourdomain.yourapp");
   
   sendBroadcast(intent);
   

3. Done. Once this Intent is broadcast the launcher should show a badge on your application icon.

4. To remove the badge again, simply send a new broadcast, this time with SHOW_MESSAGE set to false:

   intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
   

I've excluded details on how I found this to keep the answer short, but it's all available in the blog. Might be an interesting read for someone.
