Android项目实战之百度地图地点签到功能
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'
