以下是获取今天卡路里的代码：
Calendar date = new GregorianCalendar();
date.set(Calendar.HOUR_OF_DAY, 0);
date.set(Calendar.MINUTE, 0);
date.set(Calendar.SECOND, 0);
date.set(Calendar.MILLISECOND, 0);
long startTime = date.getTimeInMillis();
date.set(Calendar.HOUR_OF_DAY, 23);
date.set(Calendar.MINUTE, 59);
date.set(Calendar.SECOND, 59);
date.set(Calendar.MILLISECOND, 0);
long endTime = date.getTimeInMillis();
String calories;
DataReadRequest dataReadRequest = new DataReadRequest.Builder().read(DataType.TYPE_CALORIES_EXPENDED).
setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS).build();
Fitness.HistoryApi.readData(App.gClient, dataReadRequest).setResultCallback(
new ResolvingResultCallbacks<DataReadResult>(this.getActivity(), 0) {
@Override
public void onSuccess(DataReadResult dataReadResult) {
String calories;
DataSet dataSet = dataReadResult.getDataSet(DataType.TYPE_CALORIES_EXPENDED);
if (dataSet != null) {
List<DataPoint> dataPoint = dataSet.getDataPoints();
if (!dataPoint.isEmpty()) {
calories = dataPoint.get(0).getValue(Field.FIELD_CALORIES).toString();
txtCalories.setText(calories);
}
}
}
@Override
public void onUnresolvableFailure(Status status) {
}
});
当我设置 startDate=1 时，我可以看到卡路里计数。然而，就今天而言，没有计数。开始时间是今天午夜 12 点，结束时间是今天晚上 11:59。
