摘要 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。
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

try doing it
在启动的Activity中、发送未读消息数目广播 和 重置/清除未读消息数目广播 的调用如下:
// 发送未读消息数目广播:count为未读消息数目(int类型)
BadgeUtil.setBadgeCount(getApplicationContext(), count);
// 发送重置/清除未读消息数目广播:
BadgeUtil.resetBadgeCount(getApplicationContext());
