【问题描述】:
我需要获得所有心率测量值,而不是最小、最大和平均值,这是我能够获得的。
这是我用来从我的 java 类中读取的代码。
谢谢!
private void readDataFitnessHistory()
{
// Setting a start and end date using a range of 1 week before this moment.
Calendar cal = Calendar.getInstance();
Date now = new Date();
cal.setTime(now);
long endTime = cal.getTimeInMillis();
cal.add(Calendar.WEEK_OF_YEAR, -1);
long startTime = cal.getTimeInMillis();
java.text.DateFormat dateFormat = getDateInstance();
Log.d(TAG, "Range Start: " + dateFormat.format(startTime));
Log.d(TAG, "Range End: " + dateFormat.format(endTime));
DataReadRequest readRequest = new DataReadRequest.Builder()
// The data request can specify multiple data types to return, effectively
// combining multiple data queries into one call.
// In this example, it's very unlikely that the request is for several hundred
// datapoints each consisting of a few steps and a timestamp. The more likely
// scenario is wanting to see how many steps were walked per day, for 7 days.
.aggregate(DataType.TYPE_HEART_RATE_BPM, DataType.AGGREGATE_HEART_RATE_SUMMARY)
// Analogous to a "Group By" in SQL, defines how data should be aggregated.
// bucketByTime allows for a time span, whereas bucketBySession would allow
// bucketing by "sessions", which would need to be defined in code.
.bucketByTime(1, TimeUnit.DAYS)
.enableServerQueries()
.setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
.build();
// Invoke the History API to fetch the data with the query and await the result of
// the read request.
DataReadResult dataReadResult =
Fitness.HistoryApi.readData(mApiClient, readRequest).await(1, TimeUnit.MINUTES);
DataSet dataSet = dataReadResult.getDataSet(DataType.TYPE_HEART_RATE_BPM);
showDataSet(dataSet);
displayBpmDataForToday();
}
回应:
History: Type: com.google.heart_rate.summary
History: Start: 22 sept. 2017 10:40:06
D/DBGPRUEBA History: End: 22 sept. 2017 10:40:06
D/DBGPRUEBA History: Field: average Value: 71.13179
D/DBGPRUEBA History: Field: max Value: 86.0
D/DBGPRUEBA History: Field: min Value: 55.0
【问题讨论】:
-
TYPE_HEART_RATE_BPM(每分钟心跳次数)是否符合您的要求?
-
如果是这样,但我需要的是在指示的时间范围内获得所有测量值,而不是在指示的时间范围内的最小值、最大值和平均值。
-
我认为这还不可能。正如documentation 所述,您只能使用
com.google.heart_rate.summary数据类型来获取某个时间间隔内每分钟的平均、最大和最小节拍。 -
您好,谢谢您的评论,我认为您是对的,但是我看到您可以通过数据立方体提取数据,但我不知道它的最小周期是多少您可以对该数据进行分组。(.bucketByTime(1, TimeUnit.HOURS))

您好,谢谢您的评论,我认为您是对的,但是我看到您可以通过数据立方体提取数据,但我不知道它的最小周期是多少您可以对该数据进行分组。 (.bucketByTime(1, TimeUnit.HOURS)) 将是 1 小时的最大周期还是可以以分钟为单位设置? (.bucketByTime(10, TimeUnit.MINUTES) 我试过了,但它总是返回一个至少一小时间隔的桶。谢谢!
