【问题描述】：

我正在使用 GoogleApiClient 获取用户的纬度和经度，这就是我迄今为止所做的。我按照谷歌地图上的 Udacity 教程来做这个。我已经完全按照 Udacity 上显示的方式完成了，但是我的纬度和经度没有像教员那样显示。

没有错误，所以我看不到错误在哪里。 我安装了 Google Play Services 10.2.0 版并将其输入到 build.gradle 应用程序的依赖项部分。 非常感谢任何帮助。

public class MainActivity extends AppCompatActivity implements
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener,
    com.google.android.gms.location.LocationListener

private final String LOG_TAG = "LaurenceTestApp";
private TextView txtOutput;
private GoogleApiClient mGoogleApiClient;
private LocationRequest mLocationRequest;

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(LocationServices.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();
    txtOutput = (TextView) findViewById(R.id.txtOutput);



@Override
public void onConnected(@Nullable Bundle bundle)

    mLocationRequest = LocationRequest.create(); // Another way to write a new object
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    mLocationRequest.setInterval(10); // Always write in milliseconds

    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
    
        return;
    
    LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);


@Override
public void onLocationChanged(Location location)

    Log.i(LOG_TAG, location.toString());
    txtOutput.setText(location.toString());


@Override
public void onConnectionSuspended(int i)

    Log.i(LOG_TAG, "GoogleApiClient connection has been suspended");


@Override
public void onConnectionFailed(ConnectionResult connectionResult)

    Log.i(LOG_TAG, "GoogleApiClient connection has failed");


@Override
protected void onStart()

    super.onStart();
    mGoogleApiClient.connect();


@Override
protected void onStop()

    mGoogleApiClient.disconnect();
    super.onStop();

【问题讨论】：

你得到了什么？ Location[fused ....] 类似的东西？

@tahsinRupam 在我的手机上，显示“位置在此处”，因为我在 xml 文件中对其进行了硬编码。没有其他显示

@DimaRostopira 谢谢！我去看看。

成功了！非常感谢！

在你的 androidManifest.xml 中添加这个互联网权限，我希望这对你有用.... Go to this picture
