Google Fit中的卡路里值错误

Question

我正在尝试获取日历中设置的一天中消耗的卡路里数。问题是，即使我从未来中选择一天，每天的卡路里数字的值也介于1400和1500之间。

private void updateInfo() {

final GoogleApiClient client = new GoogleApiClient.Builder(getContext())
        .addApi(Fitness.HISTORY_API)
        .build();

client.connect();


final PendingResult<DataReadResult> dataReadResultPendingResult = Fitness.HistoryApi.readData(client, new DataReadRequest.Builder()
        .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
        .bucketByTime(1, TimeUnit.DAYS)
        .aggregate(TYPE_CALORIES_EXPENDED, AGGREGATE_CALORIES_EXPENDED)
        .build());


final Handler handler = new Handler();
new Thread() {
    @Override
    public void run() {
        final DataReadResult totalResult = dataReadResultPendingResult.await(30, SECONDS);
        if (totalResult.getStatus().isSuccess()) {

            handler.post(new Thread() {
                @Override
                public void run() {
                    quantityCaloriesSpent.setText(totalResult.getBuckets().get(0).getDataSets().get(0).getDataPoints().get(0).getValue(FIELD_CALORIES).asFloat()+ "");
                }
            });

        } else {
            // handle failure
        }
    }
}.start();

}
