Question

我的应用程序获得了Google Fit距离，但我注意到它包括骑行和跑步。有没有办法只走到步行距离？

这是我的应用程序的示例： https://github.com/francislainy/fit

// ----------- Google Fit Daily DISTANCE -----------
public static void subscribeDailyDistance() {


    Log.d(LOG_TAG, "subscribeDailyDistance was called");

    if (client != null) {

        // To create a subscription, invoke the Recording API.
        // As soon as the subscription is active, fitness data will start recording
        Fitness.RecordingApi.subscribe(client, DataType.TYPE_DISTANCE_DELTA)
                .setResultCallback(new ResultCallback<Status>() {
                    @Override
                    public void onResult(@NonNull Status status) {

                        if (status.isSuccess()) {

                            if (status.getStatusCode() == FitnessStatusCodes.SUCCESS_ALREADY_SUBSCRIBED) {
                                Log.d(LOG_TAG, "Existing subscription for activity detected.");

                            } else {
                                Log.d(LOG_TAG, "Successfully subscribed");

                            }

                            // :)
                            readDistanceToday();

                        } else {
                            Log.e(LOG_TAG, "There was a problem subscribing");
                        }

                    }
                });

    }

}


public static class VerifyDataTaskDistance extends AsyncTask<GoogleApiClient, Void, Void> {

    float total = 0;

    protected Void doInBackground(GoogleApiClient... clients) {

        PendingResult<DailyTotalResult> result = Fitness.HistoryApi.readDailyTotal(clients[0], DataType.TYPE_DISTANCE_DELTA);
        DailyTotalResult totalResult = result.await(30, TimeUnit.SECONDS);
        if (totalResult.getStatus().isSuccess()) {
            DataSet totalSet = totalResult.getTotal();
            total = totalSet.isEmpty()
                    ? 0
                    : totalSet.getDataPoints().get(0).getValue(Field.FIELD_DISTANCE).asFloat();
        } else {
            Log.e(LOG_TAG, "There was a problem getting the distance count");
        }

        Log.i(LOG_TAG, "Total distance: " + total);


        return null;
    }

    @Override
    protected void onPostExecute(Void aVoid) {

        // UI
        updateDistanceGoogle(total, MainActivity.mainActivity.getSupportFragmentManager());

    }

}

感谢您的帮助。：）

PS：根据ginnyhuang的建议添加额外代码以逐段使用

 private static DataReadRequest getDataDistanceReadRequest(int numberOfDaysPast) {

    Calendar cal = new GregorianCalendar();
    cal.setTime(new Date());
    cal.add(Calendar.DAY_OF_YEAR, -numberOfDaysPast);
    cal.set(Calendar.HOUR_OF_DAY, 0);
    cal.set(Calendar.MINUTE, 0);
    cal.set(Calendar.SECOND, 0);
    cal.set(Calendar.MILLISECOND, 0);

    long endTime = cal.getTimeInMillis();

    cal.add(Calendar.DAY_OF_YEAR, -1);

    long startTime = cal.getTimeInMillis();

    DataSource ESTIMATED_STEP_DELTAS = new DataSource.Builder()
            .setDataType(DataType.TYPE_DISTANCE_DELTA)
            .setType(DataSource.TYPE_DERIVED)
            .setStreamName("merge_distance_delta")
            .setAppPackageName("com.google.android.gms")
            .build();

    return new DataReadRequest.Builder()
            .aggregate(ESTIMATED_STEP_DELTAS, DataType.AGGREGATE_DISTANCE_DELTA)
            //.bucketByTime(1, TimeUnit.DAYS) //todo
            .bucketByActivitySegment(7, TimeUnit.DAYS)
            .aggregate(DataType.TYPE_ACTIVITY_SEGMENT, DataType.AGGREGATE_ACTIVITY_SUMMARY)
            .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
            .build();

}

和

protected Void doInBackground(Integer... params) {

        daysIndex = params[0];

        DataReadRequest dataReadRequest = getDataDistanceReadRequest(daysIndex);

        // Invoke the History API to fetch the data with the query and await the result of
        // the read request.
        DataReadResult dataReadResult =
                Fitness.HistoryApi.readData(client, dataReadRequest).await(1, TimeUnit.MINUTES);

        List<Bucket> bucketList = dataReadResult.getBuckets();

        for (Bucket bucket : bucketList) {

            if (bucket.getActivity().equals("walking")) {

                dataSet = (bucket.getDataSet(DataType.TYPE_DISTANCE_DELTA));
            }
        }

        return null;
    }

Answer 1

bucketByActivitySegment是通过活动来获得结果的关键。您可以通过不同类型的活动来获取存储桶。

前提是存储的值包含活动段。

Here是我发布的类似答案。

DataReadRequest readRequest = new DataReadRequest.Builder()
        .aggregate(DataType.TYPE_DISTANCE_DELTA, DataType.AGGREGATE_DISTANCE_DELTA)
        .bucketByActivitySegment( 1, TimeUnit.MINUTES) // just segement time over 1 minute will be list 
        .setTimeRange(startTimeLong, endTimeLong, TimeUnit.MILLISECONDS)
        .enableServerQueries()
        .build();

Fitness.getHistoryClient(context, GoogleSignIn.getLastSignedInAccount(context))
       .readData(readRequest)
       .addOnSuccessListener()
       .addOnFailureListener();
