如何从Google Fit API获取步骤？

Question

请原谅，我对Android和Google API都是全新的。我有以下代码连接到GoogleFit。我还有一个API密钥和Oauth。

我在哪里/如何使用API​​密钥和Oauth？关于如何获取它们的大量指南，但零信息在应用程序中放置它们/如何使用它们。

我如何实际使用返回的步骤。我建立了一个全球：

private int steps;

然后尝试通过以下方式设置它：

steps = (int)total;

但它什么都没做。

这是函数的其余部分。我如何实际获得步数。

 private void accessGoogleFit() {
        Calendar cal = Calendar.getInstance();
        cal.setTime(new Date());
        long endtime = cal.getTimeInMillis();
        cal.add(Calendar.YEAR, -1);
        long starttime = cal.getTimeInMillis();

        DataReadRequest readRequest = new DataReadRequest.Builder()
                .aggregate(DataType.TYPE_STEP_COUNT_DELTA, DataType.AGGREGATE_STEP_COUNT_DELTA)
                .bucketByTime(1, TimeUnit.DAYS)
                .setTimeRange(starttime, endtime, TimeUnit.MILLISECONDS)
                .build();

        Fitness.getHistoryClient(this, GoogleSignIn.getLastSignedInAccount(this))
                .readDailyTotal(DataType.TYPE_STEP_COUNT_DELTA)
                .addOnSuccessListener(new OnSuccessListener<DataSet>() {
                    @Override
                    public void onSuccess(DataSet dataSet) {
                        Log.d("Status", "Success");
                        long total = dataSet.isEmpty()
                                ? 0
                                : dataSet.getDataPoints().get(0).getValue(Field.FIELD_STEPS).asInt();
                        Log.d("Steps ", String.valueOf(total));
                        steps = (int)total; //Trying to get steps here
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Log.d("Status", "Failure", e);
                    }
                })
                .addOnCompleteListener(new OnCompleteListener<DataSet>() {
                    @Override
                    public void onComplete(@NonNull Task<DataSet> task) {
                        Log.d("Status", "Complete");

                    }
                });

    }

我一直在官方文档和StackOverflow上下。但似乎谷歌去年对API进行了重大改动，因此大多数事情已经过时，包括google自己的教程（2015年发布）。一些已更新文档的地方提供了代码片段，我不知道如何使用它们或在何处放置它们。

这就是我向Google Fit API提出请求的方式：请求FitnessOptions等

    FitnessOptions fitnessOptions = FitnessOptions.builder()
            .addDataType(DataType.AGGREGATE_STEP_COUNT_DELTA, FitnessOptions.ACCESS_READ)
            .addDataType(DataType.TYPE_DISTANCE_DELTA, FitnessOptions.ACCESS_READ)
            .addDataType(DataType.TYPE_STEP_COUNT_DELTA, FitnessOptions.ACCESS_READ)
            .build();

您需要申请GoogleSignIn.requestPermissions

我的请求功能

Calendar cal = Calendar.getInstance();
        cal.setTime(new Date());
        long endTime = cal.getTimeInMillis();
        cal.add(Calendar.WEEK_OF_YEAR, -1);
        long startTime = cal.getTimeInMillis();

        DataReadRequest readRequest = new DataReadRequest.Builder()
                .aggregate(DataType.TYPE_STEP_COUNT_DELTA, DataType.AGGREGATE_STEP_COUNT_DELTA)
//                .read(DataType.TYPE_STEP_COUNT_DELTA)
                .bucketByTime(8, TimeUnit.DAYS)
                .enableServerQueries()
                .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
                .build();

        Fitness.getHistoryClient(
                this,
                GoogleSignIn.getLastSignedInAccount(this))
                .readData(readRequest)
                .addOnSuccessListener(new OnSuccessListener<DataReadResponse>() {
                    @Override
                    public void onSuccess(DataReadResponse dataReadResponse) {
                        Log.d("TAG_F", "onSuccess: 1 " + dataReadResponse.toString());
                        Log.d("TAG_F", "onSuccess: 1 " + dataReadResponse.getStatus());
                        Log.d("TAG_F", "onSuccess: 1 " + dataReadResponse.getDataSet(DataType.TYPE_STEP_COUNT_DELTA));
                        Log.d("TAG_F", "onSuccess: 1 " + dataReadResponse.getBuckets().get(0));
                        Log.d("TAG_F", "onSuccess: 1 " + dataReadResponse.getBuckets().get(0).getDataSets().size());

                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Log.d("TAG_F", "onFailure: 1 " + e.getMessage());
                    }
                })
                .addOnCompleteListener(new OnCompleteListener<DataReadResponse>() {
                    @Override
                    public void onComplete(@NonNull Task<DataReadResponse> task) {
                        Log.d("TAG_F", "onComplete: 1 ");
                    }
                });
