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’

日历小圆点装饰，重写 DayViewDecorator

public class EventDecorator implements DayViewDecorator { private int color; private HashSet<CalendarDay> dates; public EventDecorator(int color, Collection<CalendarDay> dates) { this.color = color; this.dates = new HashSet<>(dates); } @Override public boolean shouldDecorate(CalendarDay day) { return dates.contains(day); } @Override public void decorate(DayViewFacade view) { view.addSpan(new DotSpan(7, color)); }}
