无法在 Google Fit Api 中累积过去一周的心率数据

Question

我很想从 Google Api 获取一周的心率摘要，但我只得到数据类型名称的结果。如果我只抓取特定小时，Api 每 5 分钟左右返回从 mi Mi Band 5 抓取的心率。如果有人可以提供帮助，我将不胜感激。

生成器函数：

private fun queryFitnessData2(): DataReadRequest {
    // [START build_read_data_request]
    // Setting a start and end date using a range of 1 week before this moment.
    val calendar = Calendar.getInstance(TimeZone.getTimeZone("UTC"))
    val now = Date()
    
    calendar.time = now
    val endTime = calendar.timeInMillis
    calendar.add(Calendar.WEEK_OF_YEAR, -1)
    val startTime = calendar.timeInMillis

    Log.i(TAG, "Range Start: ${dateFormat.format(startTime)}")
    Log.i(TAG, "Range End: ${dateFormat.format(endTime)}")

    return DataReadRequest.Builder()
            .aggregate(DataType.TYPE_HEART_RATE_BPM, DataType.AGGREGATE_HEART_RATE_SUMMARY)
             .enableServerQueries()
            .bucketByTime(1, TimeUnit.DAYS)
            .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
            .build();
}

数据打印机：

 private fun printData(dataReadResult: DataReadResponse) {
        // [START parse_read_data_result]
        // If the DataReadRequest object specified aggregated data, dataReadResult will be returned
        // as buckets containing DataSets, instead of just DataSets.
        if (dataReadResult.buckets.isNotEmpty()) {
            Log.i(TAG, "Number of returned buckets of DataSets is: " + dataReadResult.buckets.size)
            for (bucket in dataReadResult.buckets) {
                bucket.dataSets.forEach { dumpDataSet(it) }
            }
        } else if (dataReadResult.dataSets.isNotEmpty()) {
            Log.i(TAG, "Number of returned DataSets is: " + dataReadResult.dataSets.size)
            dataReadResult.dataSets.forEach { dumpDataSet(it) }
        }
        // [END parse_read_data_result]
    }

数据集解析器功能：

// [START parse_dataset]
    private fun dumpDataSet(dataSet: DataSet) {
        Log.i(TAG, "Data returned for Data type: ${dataSet.dataType.name}")
        val dateFormat: DateFormat = getTimeInstance()
        //THIS IS WHERE THE FOR LOOP DOESN'T WORK!!
        for (dp in dataSet.dataPoints) {
            Log.i(TAG, "Data point:")
            Log.i(TAG, "\tType: ${dp.dataType.name}")
            Log.i(TAG, "\tStart: ${dp.getStartTimeString()}")
            Log.i(TAG, "\tEnd: ${dp.getEndTimeString()}")
            dp.dataType.fields.forEach {
                Log.i(TAG, "\tField: ${it.name} Value: ${dp.getValue(it)}")
            }
        }
    }
    // [END parse_dataset]

它唯一被记录的是数据类型，即 heart.rate.summary 类型。

如果我每天都使用存储桶，则 for 循环不起作用，但如果我每天每小时都使用它们，则效果很好。非常感谢任何帮助。

我终于找到了一种汇总心率数据的方法（它适用于我的手机，但不适用于 Android Studio 的模拟器，因此请记住这一点。 首先为心率和聚合心率添加数据类型：

FitnessOptions fitnessOptions =
    FitnessOptions.builder()
        .addDataType(DataType.TYPE_HEART_RATE_BPM, FitnessOptions.ACCESS_WRITE)
        .addDataType(DataType.AGGREGATE_HEART_RATE_SUMMARY,FitnessOptions.ACCESS_WRITE)
        .build();

然后使 FitnessQuery 函数如下：

private fun queryFitnessData2(): DataReadRequest {
        // [START build_read_data_request]
        // Setting a start and end date using a range of 1 week before this moment.
        val calendar = Calendar.getInstance(TimeZone.getTimeZone("UTC"))
        val now = Date()

                calendar.time = now
        val endTime = calendar.timeInMillis
        calendar.add(Calendar.WEEK_OF_YEAR, -1)
        val startTime = calendar.timeInMillis

        Log.i(TAG, "Range Start: ${dateFormat.format(startTime)}")
        Log.i(TAG, "Range End: ${dateFormat.format(endTime)}")

        return DataReadRequest.Builder()

                 .enableServerQueries()
                .bucketByTime(1, TimeUnit.DAYS)
                .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
                .aggregate(DataType.TYPE_HEART_RATE_BPM, DataType.AGGREGATE_HEART_RATE_SUMMARY)
                .build();
}

最后将数据集转储到桶中，每个桶对应一天：

private fun printData(dataReadResult: DataReadResponse) {
        // [START parse_read_data_result]
        // If the DataReadRequest object specified aggregated data, dataReadResult will be returned
        // as buckets containing DataSets, instead of just DataSets.
        if (dataReadResult.buckets.isNotEmpty()) {
            Log.i(TAG, "Number of returned buckets of DataSets is: " + dataReadResult.buckets.size)
            for (i in 0 until dataReadResult.buckets.size) {

                for (j in 0 until dataReadResult.buckets[i].dataSets.size) {
                    dumpDataSet(dataReadResult.buckets[i].dataSets[j]);
                }
            }
        } else if (dataReadResult.dataSets.isNotEmpty()) {
            Log.i(TAG, "Number of returned DataSets is: " + dataReadResult.dataSets.size)
            dataReadResult.dataSets.forEach { dumpDataSet(it) }
        }
        // [END parse_read_data_result]
    }

    // [START parse_dataset]
private fun dumpDataSet(dataSet: DataSet) {
    Log.i(TAG, "Data returned for Data type: ${dataSet.dataType.name}")
    val dateFormat: DateFormat = getTimeInstance()
    for (dp:DataPoint in dataSet.dataPoints) {
        Log.i(TAG, "\tStart: " + dateFormat.format(dp.getStartTime(TimeUnit.MILLISECONDS)));
        Log.i(TAG, "\tEnd: " + dateFormat.format(dp.getEndTime(TimeUnit.MILLISECONDS)));
        Log.i(TAG, "\tType: " + dp.dataType.name);
        Log.i(TAG, "TEST")
        for (field in dp.dataType.fields) {
            Log.i(TAG, "TEST4")
            val fieldValue = "Field name: " + field.name.toString() + ", value: " + dp.getValue(field).asFloat();
            Log.i(TAG, fieldValue)
        }
    }
}

希望我能帮助任何在 Google 可怕的 Api 文档中苦苦挣扎的人！
