我正在开发应用程序健身应用程序，为此我使用了 google fit api。到目前为止，我成功地获取了步数、距离，但我无法获取卡路里消耗。提前致谢

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;
}

由于您没有具体说明要跟踪卡路里的内容，因此我提供了两种方式。第一种是在 RecordingAPI 的帮助下跟踪卡路里，第二种是从 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();
}
}
});
然后您可以通过以下方法获取它：
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();
}
}
/**
* Return a {@link DataReadRequest} for all step count changes in the past week.
*/
public static DataReadRequest queryFitnessData() {
DateTimeZone timeZone = DateTimeZone.forID("Asia/Kolkata");
DateTime today = new DateTime(timeZone).withTime(23,59,59,900);
DateTime startDay = today.minusWeeks(1).withTimeAtStartOfDay();
long endTime = today.getMillis();
long startTime=startDay.getMillis();
java.text.DateFormat dateFormat = getDateInstance();
DataSource ESTIMATED_CALORIES_DELTAS = new DataSource.Builder()
.setDataType(DataType.TYPE_CALORIES_EXPENDED)
.setType(DataSource.TYPE_RAW)
.setStreamName("estimated_calories")
.build();
DataReadRequest readRequest = new DataReadRequest.Builder()
.aggregate(DataType.TYPE_CALORIES_EXPENDED,DataType.AGGREGATE_CALORIES_EXPENDED)
.bucketByTime(1, TimeUnit.DAYS)
.setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
.build();
// [END build_read_data_request]
return readRequest;
}

由于您没有正确的答案，我认为这就是您所需要的
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;
}
}
