导航协议实现导航时悬浮显示车速
背景某导航巡航时才能悬浮车速，导航时是不能悬浮车速的。本人不太喜欢全屏导航，因此就写了个app自己用。
原始巡航图，带车速的。
，本来导航要是有这个车速就很好，可惜官方没有。那就自己动手咯。
目前软件已开车实测500公里，无闪退问题。下面贴下核心代码。

必须可以，但是这个玩意是调用了高德的私有广播接口，不方便提供成品，大厂不敢搞它
:lol这个倒没问题的，我自己修改了高德6.5.5的渠道版本变成全功能版，然后询问过高德产品经理，产品经理说只要不拿来盈利，分享完全没问题，后来发到了高德车机官方论坛里，已经回帖30多页了，搜索引擎搜到的6.5.5修改版，就是我发布的:lol 027rainguai 发表于 2024-2-22 09:37
好像有成品吧，有个博主叫沉默，他搞过
是的，市面上的悬浮基本都是chemo大佬的，我就是想知道，除了地图包，还有没有其他要支持的，比如什么协议之类的，我是别克车型，直接用飞屏的包不成功，只有原厂的百度可以三指飞屏 这个！！ 搞个HUD比这个好吧 有些车型方向盘遮挡仪表没发看见时速 导航时速又小很 不错 牛逼啊，自己动手，丰衣足食 怎么用啊？
这个不错 谢谢大佬 大佬江夏的啊, 我也是江夏的 cl19980429 发表于 2023-9-12 15:18
大佬江夏的啊, 我也是江夏的
嗯呢，江夏的。 楼主幸福安康，可惜不会用
