其中最大的原因就是我思考复杂了在公司系统上此BUG标题为
请确认Wifi优先级状态栏Wifi被忽略
BUG意思就是当前安卓系统状态栏图标有显示尺寸的测量如果比如需要显示8个图标已经在状态栏绘制不下则显示一个点表示省略而不希望wifi被省略
我思考了一下一直以为就是优先级问题是不是Android底层状态栏有各个图标优先级图标过多的时候优先级高的就不会被隐藏而其实最后参考了公司以前相关BUG的修改其实只是状态栏的图标大小修改即可将图标改小状态栏就可以多一个显示图标Wifi就不会被隐藏。点向后一个图标挪了一位
在尺寸文件中进行修改对这两个尺寸进行改小可以调一下刷机看一下 dimen namestatus_bar_icon_size14dip/dimendimen namestatus_bar_system_icon_size11.5dp/dimen
值得一提的是上面的逻辑超出的图标隐藏、绘制、测量相关的Java类是StatusIconContainer.Java虽然和BUG不在这改记录一下
