我正在尝试使用 Google Fit API 在我的应用中获取步数。但除了位置之外，我没有得到任何数据源。如何获取步数的数据源？ 我已经坚持了 4 天多了。请帮我解决这个问题。谢谢。下面是我正在使用的代码

   * a known auth error is being resolved, such as showing the account chooser or presenting a
   * consent dialog. This avoids common duplications as might happen on screen rotations, etc.

这对我有用，如果有人卡住，使用这个 ----

像这样初始化 FitnessClient 对象:

 private void buildFitnessClient() {
            if (mClient == null && checkPermissions()) {
                mClient = new GoogleApiClient.Builder(this)
                        .addApi(Fitness.SENSORS_API)
                        .addScope(new Scope(Scopes.FITNESS_LOCATION_READ))
                        .addConnectionCallbacks(
                                new GoogleApiClient.ConnectionCallbacks() {
                                    @Override
                                    public void onConnected(Bundle bundle) {
                                        Log.i(TAG, "Connected!!!");
                                        // Now you can make calls to the Fitness APIs.
                                        findFitnessDataSources();
                                    }

现在定义你想要作为回调获取的数据类型，我们必须将其设置为 DataType.TYPE_STEP_COUNT_DELTA，如下所示:

 private void findFitnessDataSources() {
        // [START find_data_sources]
        // Note: Fitness.SensorsApi.findDataSources() requires the ACCESS_FINE_LOCATION permission.
        Fitness.SensorsApi.findDataSources(mClient, new DataSourcesRequest.Builder()
                // At least one datatype must be specified.
                .setDataTypes(DataType.TYPE_STEP_COUNT_DELTA)

                        // Can specify whether data type is raw or derived.
                .build())
                .setResultCallback(new ResultCallback<DataSourcesResult>() {
                    @Override
                    public void onResult(DataSourcesResult dataSourcesResult) {
                        Log.i(TAG, "Result: " + dataSourcesResult.getStatus().toString());
                        for (DataSource dataSource : dataSourcesResult.getDataSources()) {
                            Log.i(TAG, "Data source found: " + dataSource.toString());
                            Log.i(TAG, "Data Source type: " + dataSource.getDataType().getName());

                            //Let's register a listener to receive Activity data!
                        if (dataSource.getDataType().equals(DataType.TYPE_STEP_COUNT_DELTA)
                                && mListener == null) {
                            Log.i(TAG, "Data source for LOCATION_SAMPLE found!  Registering.");
                            registerFitnessDataListener(dataSource,
                                    DataType.TYPE_STEP_COUNT_DELTA);
                        }
                    }
                }
            });
    // [END find_data_sources]
}

现在使用传感器 API 为提供的数据源和数据类型注册一个监听器，如下所示:

private void registerFitnessDataListener(DataSource dataSource, DataType dataType) {
        // [START register_data_listener]
        mListener = new OnDataPointListener() {
            @Override
            public void onDataPoint(DataPoint dataPoint) {
                for (Field field : dataPoint.getDataType().getFields()) {
                    Value val = dataPoint.getValue(field);
//                    Value(TotalSteps);
//                     TotalSteps=val+TotalSteps;
                    Log.i(TAG, "Detected DataPoint field: " + field.getName());
                    Log.i(TAG, "Detected DataPoint value: " + val);
                }
            }
        };

        Fitness.SensorsApi.add(
                mClient,
                new SensorRequest.Builder()
                        .setDataSource(dataSource) // Optional but recommended for custom data sets.
                        .setDataType(dataType) // Can't be omitted.
                        .setSamplingRate(1, TimeUnit.SECONDS)
                        .build(),
                mListener)
                .setResultCallback(new ResultCallback<Status>() {
                    @Override
                    public void onResult(Status status) {
                        if (status.isSuccess()) {
                            Log.i(TAG, "Listener registered!");
                        } else {
                            Log.i(TAG, "Listener not registered.");
                        }
                    }
                });
        // [END register_data_listener]
    }

也不要忘记注销您的监听器:

 private void unregisterFitnessDataListener() {
        if (mListener == null) {
            // This code only activates one listener at a time.  If there's no listener, there's
            // nothing to unregister.
            return;
        }

        // [START unregister_data_listener]
        // Waiting isn't actually necessary as the unregister call will complete regardless,
        // even if called from within onStop, but a callback can still be added in order to
        // inspect the results.
        Fitness.SensorsApi.remove(
                mClient,
                mListener)
                .setResultCallback(new ResultCallback<Status>() {
                    @Override
                    public void onResult(Status status) {
                        if (status.isSuccess()) {
                            Log.i(TAG, "Listener was removed!");
                        } else {
                            Log.i(TAG, "Listener was not removed.");
                        }
                    }
                });
        // [END unregister_data_listener]
    }
