Android Icon数字角标（BadgeNumber）的实现方式

Android Icon数字角标（BadgeNumber）的实现方式

 

http://blog.csdn.net/janice0529/article/details/44344169

Android系统 小米，三星，索尼手机发送桌面快键提醒数字图标，在Android系统中，众所周知不支持BadgeNumber，虽然第三方控件BadgeView可以实现应用内的数字提醒，但对于系统的图标，特别是app的logo图标很难实现数字标志，即使是绘图的方式不断修改，但这种方式天生弊端，实用性很差。但幸运的是，某些ROM厂商提供了私有的API，但也带来了难度，API的不同意意味着代码量的增加和兼容性问题更加突出。

我们现在来实现桌面logo或者说icon右上角的图标，先来看2张图，第一张来自互联网，第二张来自个人实践！（由于实验条件有限，只能测试小米的(⊙o⊙)…，有兴趣的同学测试一下其他的吧）

    

好了，上代码

}

注意lancherActivityClassName 必须被配置为 启动页   android.intent.category.LAUNCHER

class = "hljs xml" >  class = "hljs-tag" >< class = "hljs-name" >activity
            class = "hljs-attr" >android:name= class = "hljs-string" > "com.sample.activites.Welcome"
            class = "hljs-attr" >android:configChanges= class = "hljs-string" > "locale|keyboard|screenSize"
            class = "hljs-attr" >android:label= class = "hljs-string" > "@string/app_name"
            class = "hljs-attr" >android:screenOrientation= class = "hljs-string" > "portrait"  >
            class = "hljs-tag" >< class = "hljs-name" >intent-filter>
                class = "hljs-tag" >< class = "hljs-name" >action  class = "hljs-attr" >android:name= class = "hljs-string" > "android.intent.action.MAIN"  />

                class = "hljs-tag" >< class = "hljs-name" >category  class = "hljs-attr" >android:name= class = "hljs-string" > "android.intent.category.LAUNCHER"  />
            class = "hljs-tag" > class = "hljs-name" >intent-filter>
            class = "hljs-tag" >< class = "hljs-name" >intent-filter>
                class = "hljs-tag" >< class = "hljs-name" >action  class = "hljs-attr" >android:name= class = "hljs-string" > "android.intent.action.CREATE_SHORTCUT"  />
            class = "hljs-tag" > class = "hljs-name" >intent-filter>
        class = "hljs-tag" > class = "hljs-name" >activity>
