使用 google fit api 的卡路里消耗

Question

我正在开发 app fitness app ，为此我使用了 google fit api 。到目前为止，我已经成功地获取了步数和距离，但我无法获取卡路里消耗。提前致谢

Answer 1

您需要先设置用户的体重和身高。使用此信息计算消耗的卡路里。

这些是我用来执行此操作的方法。（mClient 是一个 GoogleApiClient 实例）

public static void saveUserHeight(int heightCentimiters) {
    // to post data
    float height = ((float) heightCentimiters) / 100.0f;
    Calendar cal = Calendar.getInstance();
    Date now = new Date();
    cal.setTime(now);
    long endTime = cal.getTimeInMillis();
    cal.add(Calendar.DAY_OF_YEAR, -1);
    long startTime = cal.getTimeInMillis();

    DataSet heightDataSet = createDataForRequest(
            DataType.TYPE_HEIGHT,    // for height, it would be DataType.TYPE_HEIGHT
            DataSource.TYPE_RAW,
            height,                  // weight in kgs
            startTime,              // start time
            endTime,                // end time
            TimeUnit.MILLISECONDS                // Time Unit, for example, TimeUnit.MILLISECONDS
    );

    com.google.android.gms.common.api.Status heightInsertStatus =
            Fitness.HistoryApi.insertData(mClient, heightDataSet)
                    .await(1, TimeUnit.MINUTES);
}

public static void saveUserWeight(float weight) {
    // to post data
    Calendar cal = Calendar.getInstance();
    Date now = new Date();
    cal.setTime(now);
    long endTime = cal.getTimeInMillis();
    cal.add(Calendar.DAY_OF_YEAR, -1);
    long startTime = cal.getTimeInMillis();

    DataSet weightDataSet = createDataForRequest(
            DataType.TYPE_WEIGHT,    // for height, it would be DataType.TYPE_HEIGHT
            DataSource.TYPE_RAW,
            weight,                  // weight in kgs
            startTime,              // start time
            endTime,                // end time
            TimeUnit.MILLISECONDS                // Time Unit, for example, TimeUnit.MILLISECONDS
    );

    com.google.android.gms.common.api.Status weightInsertStatus =
            Fitness.HistoryApi.insertData(mClient, weightDataSet)
                    .await(1, TimeUnit.MINUTES);
}

public static DataSet createDataForRequest(DataType dataType,
                                           int dataSourceType,
                                           Object values,
                                           long startTime,
                                           long endTime,
                                           TimeUnit timeUnit) {
    DataSource dataSource = new DataSource.Builder()
            .setAppPackageName(appContext)
            .setDataType(dataType)
            .setType(dataSourceType)
            .build();

    DataSet dataSet = DataSet.create(dataSource);
    DataPoint dataPoint = dataSet.createDataPoint().setTimeInterval(startTime, endTime, timeUnit);

    if (values instanceof Integer) {
        dataPoint = dataPoint.setIntValues((Integer) values);
    } else {
        dataPoint = dataPoint.setFloatValues((Float) values);
    }

    dataSet.add(dataPoint);

    return dataSet;
}

既然你没有正确的答案，我想这就是你需要的

      public void displayCaloriesDataForToday() {



                  DailyTotalResult resultcalories = Fitness.HistoryApi.readDailyTotal( mGoogleApiClient, DataType.TYPE_CALORIES_EXPENDED).await();
                    showStepDataSet(resultcalories.getTotal());

                }


    private void showStepDataSet(DataSet caloriesDataSet) {


            for (DataPoint dp : caloriesDataSet.getDataPoints()) {

                    //Do what you need

                }
            }

 public class ViewTodaysStepCountTask extends AsyncTask<Void, Void, Void> {
        protected Void doInBackground(Void... params) {
            Timer timer = new Timer();

            timer.schedule( new TimerTask() {
                public void run() {
                    displayCaloriesDataForToday();
                }
            }, 0, 1*1000);

            return null;
        }
    }

      public void displayCaloriesDataForToday() {

              DailyTotalResult resultcalories = Fitness.HistoryApi.readDailyTotal( mGoogleApiClient, DataType.TYPE_CALORIES_EXPENDED).await();
                showStepDataSet(resultcalories.getTotal());

            }

 private void showStepDataSet(DataSet caloriesDataSet) {
    float total_cal = 0;
        total_cal = totalSet.isEmpty()
                    ? 0
                    : totalSet.getDataPoints().get(0).getValue(Field.FIELD_CALORIES).asFloat();
        }

            public class ViewTodaysStepCountTask extends AsyncTask<Void, Void, Void> {
    protected Void doInBackground(Void... params) {
        Timer timer = new Timer();

        timer.schedule( new TimerTask() {

        }, 0, 1*1000);

        return null;
    }
}

Answer 4

由于您没有具体说明要跟踪卡路里的内容，因为我提供了两个 ways.First 一个是在 RecordingAPI 的帮助下跟踪卡路里，第二个是从 Fit Store 获取卡路里消耗.

要获取当前燃烧的卡路里，您必须使用卡路里订阅 RecordingAPI：

Fitness.RecordingApi.subscribe(mClient, DataType.TYPE_CALORIES_EXPENDED)
            .setResultCallback(new ResultCallback<Status>() {
                @Override
                public void onResult(Status status) {
                    if (status.isSuccess()) {
                        if (status.getStatusCode()
                                == FitnessStatusCodes.SUCCESS_ALREADY_SUBSCRIBED) {
                            disRec=true;
                            new SharedPrefManager(MainActivityWithSpinner.this).setTracking(true);
                        } else {
                            new SharedPrefManager(MainActivityWithSpinner.this).setTracking(true);
                            disRec=true;
                            Toast.makeText(MainActivityWithSpinner.this,"Recording started for Calories",Toast.LENGTH_SHORT).show();
                        }
                    } else {
                        Toast.makeText(MainActivityWithSpinner.this,"Distance  Recording faced some issues.Try again.",Toast.LENGTH_SHORT).show();
                    }
                }
            });

那么您可以通过以下方法获取：

public String getCalories(long startTime,long endTime){
    String steps="";
    DataReadRequest readRequest = new DataReadRequest.Builder()
            .aggregate(DataType.TYPE_CALORIES_EXPENDED, DataType.AGGREGATE_CALORIES_EXPENDED)
            .bucketByTime(1, TimeUnit.DAYS)
            .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
            .build();
    DataReadResult dataReadResult =
            Fitness.HistoryApi.readData(MainActivityWithSpinner.mClient, readRequest).await(1, TimeUnit.MINUTES);

    if(dataReadResult.getBuckets().size() > 0){
        for (Bucket bucket : dataReadResult.getBuckets()) {
            List<DataSet> dataSets = bucket.getDataSets();
            for (DataSet dataSet1 : dataSets) {
                for(DataPoint dataPoint:dataSet1.getDataPoints()){
                    for (Field field:dataPoint.getDataType().getFields()){
                        steps=String.format("%.2f",Float.parseFloat(dataPoint.getValue(field)+""))+"";
                    }
                }
            }

        }
    }
    return steps;
}

要从 Google Fit Store 获取数据，您可以使用以下方法：

public  class InsertAndVerifyDataTask extends AsyncTask<Void, Void, Void> {
    String result="";
    long total;
    boolean datainsertionFailed=false;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        avLoadingIndicatorView.show();
    }

    protected Void doInBackground(Void... params) {

        DataReadRequest readRequest = queryFitnessData();

        DataReadResult dataReadResult =
                Fitness.HistoryApi.readData(MainActivityWithSpinner.mClient, readRequest).await(1, TimeUnit.MINUTES);
        PendingResult<DailyTotalResult> result =
                Fitness.HistoryApi.readDailyTotalFromLocalDevice(MainActivityWithSpinner.mClient, TYPE_CALORIES_EXPENDED);
        DailyTotalResult totalResult = result.await(30, SECONDS);
        if (totalResult.getStatus().isSuccess()) {
            DataSet totalSet = totalResult.getTotal();
            total = totalSet.isEmpty()
                    ? 0
                    : (long)totalSet.getDataPoints().get(0).getValue(FIELD_CALORIES).asFloat();
        } else {
            // handle failure
        }
        DateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
        DateFormat dateFormatFull = new SimpleDateFormat("dd/MM/yy");
        DateFormat dateFormatTemp=new SimpleDateFormat("E");
        datax.clear();
        if(dataReadResult.getBuckets().size() > 0){
            for (Bucket bucket : dataReadResult.getBuckets()) {
                List<DataSet> dataSets = bucket.getDataSets();
                for (DataSet dataSet1 : dataSets) {
                    for(DataPoint dataPoint:dataSet1.getDataPoints()){
                        for (Field field:dataPoint.getDataType().getFields()){
                            String dayOfWeek=dateFormatTemp.format(new Date(dataPoint.getStartTime(TimeUnit.MILLISECONDS)));
                            Calendar cal=Calendar.getInstance();
                            cal.setTime(new Date(dataPoint.getStartTime(TimeUnit.MILLISECONDS)));
                            int day=cal.get(Calendar.DAY_OF_MONTH);
                            String month=getMonth(cal.get(Calendar.MONTH));
                            String fullDate=dayOfWeek+", "+day+" "+month;
                            StepCountModel stepCountModel=new StepCountModel(String.format("%.2f",Float.parseFloat(dataPoint.getValue(field)+""))+"",fullDate,dateFormat.format(new Date(dataPoint.getStartTime(TimeUnit.MILLISECONDS))),dateFormat.format(new Date(dataPoint.getEndTime(TimeUnit.MILLISECONDS))));
                            datax.add(stepCountModel);
                            //result+="Field: "+field.getName()+"Value: "+dataPoint.getValue(field)+"Start: "+dateFormat.format(dataPoint.getStartTime(TimeUnit.MILLISECONDS))+"End: "+dateFormat.format(dataPoint.getEndTime(TimeUnit.MILLISECONDS))+"\n";
                        }
                    }
                }
            }
        }

        return null;
    }

    @Override
    protected void onPostExecute(Void aVoid) {
        super.onPostExecute(aVoid);
        todayCount.setText("Total Calories expended today: "+total+" cal");
        customAdapter.notifyDataSetChanged();
        avLoadingIndicatorView.hide();
    }
}
