核心代码
1.发起检索请求
JAVA
/**
* 查询轨迹的开始时间
*/
private long startTime = CommonUtil.getCurrentTime();
/**
* 查询轨迹的结束时间
*/
private long endTime = CommonUtil.getCurrentTime();
// 停留时长
int stayTime = 100;
/**
* 历史轨迹请求
*/
HistoryTrackRequest historyTrackRequest = new HistoryTrackRequest();
/**
* 创建纠偏选项实例
*/
ProcessOption processOption = new ProcessOption();
/**
* 轨迹排序规则
*/
private SortType sortType = SortType.asc;
// 创建停留点查询请求实例
StayPointRequest stayPointRequest = new StayPointRequest(trackApp.getTag(), trackApp.serviceId, trackApp.entityName,startTime, endTime, stayTime, processOption, CoordType.bd09ll);
// 设置限速值
ThresholdOption thresholdOption = new ThresholdOption();
// 创建行为查询请求实例
DrivingBehaviorRequest drivingBehaviorRequest = new DrivingBehaviorRequest(trackApp.getTag(), trackApp.serviceId, trackApp.entityName,startTime, endTime, thresholdOption, processOption, CoordType.bd09ll);
// 停留点查询
trackApp.mClient.queryStayPoint(stayPointRequest, mAnalysisListener);
// 行为查询
trackApp.mClient.queryDrivingBehavior(drivingBehaviorRequest, mAnalysisListener);
// 创建历史轨迹请求实例
trackApp.initRequest(historyTrackRequest);
historyTrackRequest.setEntityName(trackApp.entityName);
historyTrackRequest.setStartTime(startTime);
historyTrackRequest.setEndTime(endTime);
historyTrackRequest.setPageIndex(pageIndex);
historyTrackRequest.setPageSize(Constants.PAGE_SIZE);
trackApp.mClient.queryHistoryTrack(historyTrackRequest, mTrackListener);
