我正在尝试使用Google Fit API在我的应用中获取步数。但我没有获得除Location之外的任何数据源。如何获取步数的数据源？ 我被困在这4天多了。请帮助我。谢谢。以下是我正在使用的代码

这适用于我，如果有人卡住，请使用此----
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();
}
现在定义要作为回调的数据类型，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Sensors API为所提供的DataSource和DataType注册一个侦听器，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]
}
另外，请不要忘记取消注册您的听众：
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]
}

我遇到了同样的问题
我只是通过改变
解决了这个问题.setDataSourceTypes(DataSource.TYPE_RAW)
到
.setDataSourceTypes(DataSource.TYPE_DERIVED)
尝试更改它。

好的，我的朋友。请试一试。它还没有统计步骤，但它可以读取您的步数数据类型。当我尝试你的时候，我在conset屏幕上遇到了OAuth问题。我用addApi做了一些改变。
public class MainActivity extends ActionBarActivity {
public static final String TAG = "BasicSensorsApi";

private static final int REQUEST_OAUTH = 1;
private static final String AUTH_PENDING = "auth_state_pending";

private GoogleApiClient mClient = null;
// [END auth_variable_references]
@Override

super.onCreate(savedInstanceState);
// Put application specific code here.
// [END auth_oncreate_setup_beginning]
setContentView(R.layout.activity_main);
// This method sets up our custom logger, which will print all log messages to the device
// screen, as well as to adb logcat.
// [START auth_oncreate_setup_ending]
if (savedInstanceState != null) {
authInProgress = savedInstanceState.getBoolean(AUTH_PENDING);
}
buildFitnessClient();
}

答案 3 :(得分：1)
同时在onDataPointListener
中更改此行 Log.i(TAG, "Detected DataPoint value: " + val);
到
Log.i(TAG, "Detected DataPoint value: " + val.asInt());
你会得到步数，但它对我来说很有趣。例如，它达到25步但然后它下降而不是计数。至少我让步计数器做了一些事情。
