java – Google Fit API,获取每项活动消耗的卡路里

所以我正在尝试创建一个连接到Google Fit的应用程序,并以非常精简的方式向用户显示他们的数据,而且我很难找到用户每天为每个活动消耗的卡路里.我可以获得一整天的总卡路里,以及用户每天所做的每项活动,但不能获得每项活动消耗的卡路里.

链接到GitHub：https://github.com/drb56/FitTest
我只添加了java代码而不是任何xml的东西. Google Fit代码位于FitTestFragment.java中.
我将在下面粘贴一些关键代码：

这是我连接到google fit API客户端的位置：

mClient = new GoogleApiClient.Builder(getContext())
            .addApi(Fitness.HISTORY_API)
            .addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ))
            .addConnectionCallbacks(this)
            .enableAutoManage(getActivity(),new GoogleApiClient.OnConnectionFailedListener() {
            @Override
            public void onConnectionFailed(ConnectionResult result) {
                Log.i("MyApp","Google Play services connection failed. Cause: " +
                        result.toString());
        }})
        .build();

这是我为特定信息制作DataReadRequest的地方：

DataReadRequest readRequest = new DataReadRequest.Builder()
                         .aggregate(DataType.TYPE_CALORIES_EXPENDED,DataType.AGGREGATE_CALORIES_EXPENDED)
                        .aggregate(DataType.TYPE_ACTIVITY_SEGMENT,DataType.AGGREGATE_ACTIVITY_SUMMARY)
                        .bucketByTime(1,TimeUnit.DAYS)
                        .setTimeRange(startTime,endTime,TimeUnit.MILLISECONDS)
                        .build();

    DataReadResult dataReadResult = Fitness.HistoryApi.readData(mClient,readRequest).await(1,TimeUnit.MINUTES);


    if (dataReadResult.getBuckets().size() > 0)
    {
        Log.i("MyApp","Number of returned buckets of DataSets is: "
                + dataReadResult.getBuckets().size());
        for (Bucket bucket : dataReadResult.getBuckets())
        {
            List<DataSet> dataSets = bucket.getDataSets();
                     for (DataSet dataSet : dataSets)
                    {
                        dumpDataSet(dataSet);
                    }
                }
             }
            else
            {
                Log.i("MyApp","No data");
            }

以下是我的输出对于某些活动和消耗的卡路里的影响：

Data point:

    Start: 2:58:13 PM
    End: 2:58:13 PM

DataReadRequest readRequest = new DataReadRequest.Builder()
            .aggregate(DataType.TYPE_CALORIES_EXPENDED,DataType.AGGREGATE_CALORIES_EXPENDED)
            .bucketByActivityType(1,TimeUnit.SECONDS)
            .setTimeRange(startTime,TimeUnit.MILLISECONDS)
            .build();

bucket.getActivity();
