现在Android中有许多的应用仿苹果的在应用图标上显示小红点。当然有着一些手机ROM对小红点的支持,比如小米,三星等。google的api是没有提供这项工能的,这项功能一般都是厂商自己定制的,所以让开发者着实头痛,我也是弄了2天,不是所有的机型都可以.以后再一点点完善吧.希望对读文章的人,或也在受此困惑的人有点帮助!
BadgeUtil类:

总结:
小米,三星,索尼,htc,朵唯.手中有的手机基本小红点功能都是没有问题的.
oppo:厂商不提供此功能,只对于市面上排名前5的商用聊天提供,还说对企业内部的im会提供此功能,不过必须要集成oppo证书.
华为:与oppo说法一样,但是按上面代码测试,华为的部分机型是可以实现的.荣耀6和6p没有效果.
vivo:部分手机有效果,vivo xplay5 x7 没有效果.
至于锤子,魅族,金立等,网上说是不支持此功能的,因为没有测试机,并没有验证.
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持编程小技巧。
