我尝试使用Android代码从Google Fit中读取血压值，但无法读取该值并返回以下日志
血压记录：
返回的数据集存储桶数为：1
数据集：[DataSet {d：blood_pressure.summary：gms：aggregated []}]
名称：com.google.blood_pressure.summary
字段： [blood_pressure_systolic_maxage（f），blood_pressure_systolic_max（f）， blood_pressure_systolic_min（f），blood_pressure_diastolic_average（f）， blood_pressure_diastolic_max（f），blood_pressure_diastolic_min（f）， body_position（i），blood_pressure_measurement_location（i）]
数据点值：[]
我检查了google fit，并输入了血压和心率，并能够读取心率值。
心率日志：
返回的数据集存储桶数为：1数据集： [DataSet {d：heart_rate.summary：gms：聚合了[RawDataPoint {[81.0， 81.0，81.0] @ 1531305031000000000，1531305031000000000}]}]]名称：com.google.heart_rate.summary字段：[average（f），max（f），min（f）]
数据点值：[DataPoint {[81.0，81.0，81.0] @ [1531305031000000000，1531305031000000000，raw = 0，insert = 0]（d：heart_rate.summary：gms：aggregated r：heart_rate.bpm：iHealthMyVitals.V2 ：ContentValues-bp速率计数）}]
数据点：类型：com.google.heart_rate.summary开始：4:00:31 PM结束： 4:00:31 PM字段：平均值，值：81.0字段：最大值，值：81.0 字段：min，值：81.0
这是我的完整代码：

}
}
@Override
public void onClick(View view) {
switch (view.getId()) {

如何解决此问题？还是除REST api之外的其他任何读取血压数据的选项。
答案 0 :(得分：0)
使用这样的构建器：
return new DataReadRequest.Builder()
.aggregate(HealthDataTypes.TYPE_BLOOD_PRESSURE,HealthDataTypes.AGGREGATE_BLOOD_PRESSURE_SUMMARY)
.bucketByTime(1, TimeUnit.DAYS) //important thing
.setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
.enableServerQueries()
.build();
