近日做了一个需求，要求设备录音中的时候，状态栏显示一个动态图标，提醒用户处于录音中状态，录音结束则动态图标停止显示。
软件版本：android8.1
硬件平台：展讯
最开始UI提供了一个三个图层的icon，结果设置进去发现背景图层一直存在，相当丑陋，后来了解到状态栏图标都是一些矢量xml文件，需要svg矢量图转为xml格式（Android studio就可以转，具体可百度），于是将svg格式转化成了矢量xml，结果发现设置进去，依然有背景图层，后来修改了xml中一个参数，关于透明度的，android:fillAlpha 这个值改为0，图标就透明了。
素材OK了，下边直接粘贴代码改动：

大概的实现逻辑做个说明，进入录音中后，相关app会发送自定义广播，附带录音状态字段，收到广播后，调整图标的显示和隐藏，其中闪烁的效果是用了延迟的msg，用handler实现的。
自己可以通过adb命令模拟广播事件，进行简单测试。
比如发送模拟录音开始的广播 adb shell am broadcast -a IFLYTEK_RECORD_STATE --ei state 1
停止录音广播 adb shell am broadcast -a IFLYTEK_RECORD_STATE --ei state 0
欢迎留言讨论～～～～如果有更简便的闪烁图标方法的话！
