Cannot accumulate heart rate data in Google Fit Api for the past week

问题

我正在尝试从Google API中获取一周的心率摘要数据，但我只得到了数据类型名称，没有结果。如果我只获取特定小时的数据，API会返回大约每5分钟从我的Mi Band 5抓取的心率数据。如果有人能帮忙，我将非常感激。

**构建函数：**

```kotlin
private fun queryFitnessData2(): DataReadRequest {
    // [START build_read_data_request]
    // 使用1周前到现在的时间范围设置开始和结束日期。
    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()
}

数据打印函数：

private fun printData(dataReadResult: DataReadResponse) {
    // [START parse_read_data_result]
    // 如果DataReadRequest对象指定了聚合数据，dataReadResult将作为包含DataSets的bucket返回，而不仅仅是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]
}

数据集解析函数：

// [START parse_dataset]
private fun dumpDataSet(dataSet: DataSet) {
    Log.i(TAG, "Data returned for Data type: ${dataSet.dataType.name}")
    val dateFormat: DateFormat = getTimeInstance()
    // 这是循环无法正常工作的地方！！
    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]

唯一记录的是数据类型，即心率摘要类型。

如果我对每天使用桶（buckets），for循环就不起作用，但如果我对每天的每个小时使用桶，它就能正常工作。非常感谢任何帮助。

I am tyrying to grab the Heart Rate Summary for one week from the Google Api, but I get no result just the datatype name. If I grab only for a specific hour the Api return the heart rate grabbed from mi Mi Band 5 every 5 minutes or so. If anyone could help I would be grateful.

**Builder Function:**

    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(&quot;UTC&quot;))
        val now = Date()
        
        calendar.time = now
        val endTime = calendar.timeInMillis
        calendar.add(Calendar.WEEK_OF_YEAR, -1)
        val startTime = calendar.timeInMillis
    
        Log.i(TAG, &quot;Range Start: ${dateFormat.format(startTime)}&quot;)
        Log.i(TAG, &quot;Range End: ${dateFormat.format(endTime)}&quot;)
    
        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();
    }


**Data Printer:**

   

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

**Dataset Parser Function:**

    // [START parse_dataset]
        private fun dumpDataSet(dataSet: DataSet) {
            Log.i(TAG, &quot;Data returned for Data type: ${dataSet.dataType.name}&quot;)
            val dateFormat: DateFormat = getTimeInstance()
            //THIS IS WHERE THE FOR LOOP DOESN&#39;T WORK!!
            for (dp in dataSet.dataPoints) {
                Log.i(TAG, &quot;Data point:&quot;)
                Log.i(TAG, &quot;\tType: ${dp.dataType.name}&quot;)
                Log.i(TAG, &quot;\tStart: ${dp.getStartTimeString()}&quot;)
                Log.i(TAG, &quot;\tEnd: ${dp.getEndTimeString()}&quot;)
                dp.dataType.fields.forEach {
                    Log.i(TAG, &quot;\tField: ${it.name} Value: ${dp.getValue(it)}&quot;)
                }
            }
        }
        // [END parse_dataset]


The only thing it gets logged is the data type which is the heart.rate.summary type.

Thefor loop doesn&#39;t work if I use the buckets for each day but works fine if I use them for each hour of the day. Any help is much appreciated.

我终于找到了一种方法来汇总心率数据（它在我的手机上运行正常，但在Android Studio的模拟器上不行，记住这一点）。
首先为心率和汇总心率添加数据类型：

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

然后按以下方式创建FitnessQuery函数：

private fun queryFitnessData2(): DataReadRequest {
    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，在每个桶中转储数据集，每个桶对应一天：

private fun printData(dataReadResult: DataReadResponse) {
    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) }
    }
}

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)
        for (field in dp.dataType.fields) {
            val fieldValue = "Field name: " + field.name.toString() + ", value: " + dp.getValue(field).asFloat()
            Log.i(TAG, fieldValue)
        }
    }
}

希望我对那些在使用谷歌可怕的API文档时遇到困难的人有所帮助！

英文:

I finally found a way to aggregate Heart Rate Data ( it works on my phone but not on the Android Studio's Emulator so have that in mind.
First add a data type for the heart rate and the aggregated heart rate:

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

Then make the FitnessQuery Function as follows:

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(&quot;UTC&quot;))
        val now = Date()

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

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

        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();
}

And finally the dataset dump in buckets where each bucket corresponds to one day:

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, &quot;Number of returned buckets of DataSets is: &quot; + 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, &quot;Number of returned DataSets is: &quot; + dataReadResult.dataSets.size)
            dataReadResult.dataSets.forEach { dumpDataSet(it) }
        }
        // [END parse_read_data_result]
    }

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

Hope I helped anyone struggling with Google's horrible Api Documentation!
