我目前正在尝试使用Google Fit API。这是我第一个使用API的应用，我主要是关注Google的文档。
以下是我的代码，似乎有问题
我遇到的问题是它似乎没有更新步骤计数器。
public class MainActivity extends Activity
implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private static final String TAG = "FitActivity";
//[START Auth_Variable_References]
private static final int REQUEST_OAUTH = 1;
// [END auth_variable_references]
private GoogleApiClient mClient = null;
int mInitialNumberOfSteps = 0;
private TextView mStepsTextView;
private boolean mFirstCount = true;
// Create Builder View
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mStepsTextView = (TextView) findViewById(R.id.textview_number_of_steps);
}
private void connectFitness() {
Log.i(TAG, "Connecting...");
// Create the Google API Client
mClient = new GoogleApiClient.Builder(this)
// select the Fitness API
.addApi(Fitness.API)
// specify the scopes of access
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ))
.addScope(new Scope(Scopes.FITNESS_LOCATION_READ))
.addScope(new Scope(Scopes.FITNESS_BODY_READ_WRITE))
// provide callbacks
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
// Connect the Google API client
mClient.connect();
}
// Manage OAuth authentication
@Override
public void onConnectionFailed(ConnectionResult result) {
// Error while connecting. Try to resolve using the pending intent returned.
if (result.getErrorCode() == ConnectionResult.SIGN_IN_REQUIRED ||
result.getErrorCode() == FitnessStatusCodes.NEEDS_OAUTH_PERMISSIONS) {
try {
// Request authentication
result.startResolutionForResult(this, REQUEST_OAUTH);
} catch (IntentSender.SendIntentException e) {
Log.e(TAG, "Exception connecting to the fitness service", e);
}
} else {
Log.e(TAG, "Unknown connection issue. Code = " + result.getErrorCode());
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_OAUTH) {
if (resultCode == RESULT_OK) {
// If the user authenticated, try to connect again
mClient.connect();
}
}
}
@Override
public void onConnectionSuspended(int i) {
// If your connection gets lost at some point,
// you'll be able to determine the reason and react to it here.
if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) {

if (status.isSuccess()) {
Log.d(TAG, "listener registered");
// listener registered
} else {
Log.d(TAG, "listener not registered");
// listener not registered
}
}
});
}
// Update the Text Viewer with Counter of Steps..
private void updateTextViewWithStepCounter(final int numberOfSteps) {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getBaseContext(), "On Datapoint!", Toast.LENGTH_SHORT);
if(mFirstCount && (numberOfSteps != 0)) {
mInitialNumberOfSteps = numberOfSteps;
mFirstCount = false;
}
if(mStepsTextView != null){
mStepsTextView.setText(String.valueOf(numberOfSteps - mInitialNumberOfSteps));
}
}
});
}
//Start
@Override
protected void onStart() {
super.onStart();
mFirstCount = true;
mInitialNumberOfSteps = 0;
if (mClient == null || !mClient.isConnected()) {
connectFitness();
}
}
//Stop
@Override

super.onStop();
if(mClient.isConnected() || mClient.isConnecting()) mClient.disconnect();
mInitialNumberOfSteps = 0;
mFirstCount = true;
}

首先， 按照以下步骤在Google API控制台中启用Fitness API并获取OAuth 2.0客户端ID。
2. 选择一个项目，或者创建一个新项目。对Android和REST版本的应用程序使用相同的项目。
3. 。点击“继续”以启用Fitness API。
4. 。点击转到凭据。
5. 点击新凭据，然后选择OAuth客户端ID。
6。在应用类型下，选择Android。
7。在结果对话框中，输入应用的SHA-1指纹和包名称。例如：
BB：0D：AC：74：D3：21：E1：43：67：71：9B：62：91：AF：A1：66：6E：44：5D：75
com.example.android.fit-示例
8. 。点击“创建”。您的新Android OAuth 2.0客户端ID和密码会显示在项目的ID列表中。 OAuth 2.0客户端ID是一串字符，如下所示：

注意： ::有时在某些设备中它不会检测步骤值，因此每当您开发和使用此代码始终卸载应用程序然后重新安装应用程序时。然后这很好。

答案 1 :(得分：1)
您可以尝试 OrangeGangster 中的StepSensor库。
它包含一个自定义Service，允许从Android 4.4中引入的Sensor.TYPE_STEP_COUNTER中收集数据（仅适用于支持此硬件功能的设备）。
答案 2 :(得分：1)
此代码适合我！
构建客户端：
mClient = new GoogleApiClient.Builder(this)
.addApi(Fitness.SENSORS_API)
.addScope(new Scope(Scopes.FITNESS_BODY_READ_WRITE))
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
调用传感器API：
private void invokeSensorsAPI() {
Fitness.SensorsApi.add(
mClient,
new SensorRequest.Builder()
.setDataType(DataType.TYPE_STEP_COUNT_DELTA)
.setSamplingRate(1, TimeUnit.SECONDS)
.build(),
this)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
if (status.isSuccess()) {
Log.i(TAG, "Sensor Listener registered!");
} else {
Log.i(TAG, "Sensor Listener not registered.");
}
}
});
}
接收数据：
@Override
public void onDataPoint(DataPoint dataPoint) {
for (Field field : dataPoint.getDataType().getFields()) {
Value val = dataPoint.getValue(field);
Log.i(TAG, "Detected DataPoint field: " + field.getName());
Log.i(TAG, "Detected DataPoint value: " + val);
final int value = val.asInt();
if (field.getName().compareToIgnoreCase("steps") == 0) {
runOnUiThread(new Runnable() {
@Override
public void run() {
tv.setText("Value" + value)
}
});
}
}
}
我希望它有所帮助

我认为你在这里犯了错误
if (resultCode == RESULT_OK) {
// If the user authenticated, try to connect again
mClient.connect()
}
而应该是
if (resultCode != RESULT_OK) {
// If the user is not authenticated, try to connect again/ resultcode = RESULT_CANCEL
mClient.connect()
} else {
onConnected(null);
}
通过您的代码调用invokeFitnessApis将永远不会被调用，因为您在成功连接后重新连接了googleapiclient。
