Android项目实战之百度地图地点签到功能项目实战之百度地图地点签到功能主要介绍了Android项目实战之百度地图地点签到功能，本文通过实例代码给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下前言:先写个简单的地点签到功能，如果日后有时间细写的话，会更加好好研究一下百度地图api,做更多逻辑判断。这里主要是调用百度地图中的场景定位中的签到场景。通过官方文档进行api集成。通过GPS的定位功能，获取地理位置，时间，用户名进行存储。之后通过日历显示历史签到记录。效果图： /**百度地图sdk**/ implementation files('libs/BaiduLBS_Android.jar') /**日历选择器**/ implementation 'com.prolificinteractive:material-calendarview:1.4.3' 签到布局：
