Google Fit API,可获得每项活动消耗的卡路里

Question

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内容.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(), 0, 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");
            }

这是我的输出看起来像一些活动和消耗的卡路里:

Data point:
    Type: com.google.calories.expended
    Date: 06/09/2016
    Start: 2:58:13 PM
    End: 2:58:13 PM
    Field: calories Value: 2555.9749
Data point:
    Type: com.google.activity.summary
    Date: 06/09/2016
    Start: 2:58:13 PM
    End: 2:58:13 PM
    Field: activity Value: 3
    Field: duration Value: 76513626
    Field: num_segments Value: 17
Data point:
    Type: com.google.activity.summary
    Date: 06/09/2016
    Start: 4:13:58 PM
    End: 12:41:04 PM
    Field: activity Value: 7
    Field: duration Value: 4553146
    Field: num_segments Value: 17

Answer 1

您需要使用 Fitness.SESSIONS_API，而不是 Fitness.HISTORY_API。会话表示用户执行健身活动的时间间隔。
