我已经做了一个项目，从中我们可以得到准确的位置使用谷歌播放服务，GPS和网络提供商。这个项目可以在这里找到。

寻找最佳位置的策略是，首先从谷歌播放服务获取位置，如果找到位置，然后检查天气是否更好，如果发现位置为空，重新启动谷歌播放服务，并尝试从Android定位API获取位置。在更改侦听器上注册位置，当找到更好的位置时，回调将其返回给主活动。

在代码中使用和实现非常简单，我们只需要嵌入两个类，即LocationManagerInterface和SmartLocationManager, LocationActivity实现接口并使用SmartLocationManager获取位置。

}

这是位置管理器类

            return currentBestLocation;
        }

        // Check whether the new location fix is more or less accurate
        int accuracyDelta = (int) (location.getAccuracy() - currentBestLocation.getAccuracy());
        boolean isLessAccurate = accuracyDelta > 0;

}

我们可以将它与activity或fragment一起使用，这里我将它与activity一起使用

import android.location.Location;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
import android.widget.Toast;

import com.example.raza.locationaware.location.LocationManagerInterface;
import com.example.raza.locationaware.location.SmartLocationManager;
import com.google.android.gms.location.LocationRequest;

public class LocationActivity extends AppCompatActivity implements LocationManagerInterface {

    public static final String TAG = LocationActivity.class.getSimpleName();

    SmartLocationManager mLocationManager;
    TextView mLocalTV, mLocationProviderTV, mlocationTimeTV;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_location);
        mLocationManager = new SmartLocationManager(getApplicationContext(), this, this, SmartLocationManager.ALL_PROVIDERS, LocationRequest.PRIORITY_HIGH_ACCURACY, 10 * 1000, 1 * 1000, SmartLocationManager.LOCATION_PROVIDER_RESTRICTION_NONE); // init location manager
        mLocalTV = (TextView) findViewById(R.id.locationDisplayTV);
        mLocationProviderTV = (TextView) findViewById(R.id.locationProviderTV);
        mlocationTimeTV = (TextView) findViewById(R.id.locationTimeFetchedTV);
    }

    protected void onStart() {
        super.onStart();
        mLocationManager.startLocationFetching();
    }

    protected void onStop() {
        super.onStop();
        mLocationManager.abortLocationFetching();
    }

    @Override
    protected void onPause() {
        super.onPause();
        mLocationManager.pauseLocationFetching();
    }

    @Override
    public void locationFetched(Location mLocal, Location oldLocation, String time, String locationProvider) {
        Toast.makeText(getApplication(), "Lat : " + mLocal.getLatitude() + " Lng : " + mLocal.getLongitude(), Toast.LENGTH_LONG).show();
        mLocalTV.setText("Lat : " + mLocal.getLatitude() + " Lng : " + mLocal.getLongitude());
        mLocationProviderTV.setText(locationProvider);
        mlocationTimeTV.setText(time);
    }
}

希望能有所帮助，如果你能提出任何改进建议，请张贴在git上。谢谢。

Edit 2022:不要使用这个库，因为该库有内存泄漏，不再支持/更新。

我将推荐使用智能位置库 使用起来非常简单，它很好地包装了位置逻辑。

启动位置服务:

SmartLocation.with(context).location()
    .start(new OnLocationUpdatedListener() { ... });

如果你只想获得一个单一的位置(不是周期性的)，你可以使用oneFix修饰符。例子:

SmartLocation.with(context).location()
    .oneFix()
    .start(new OnLocationUpdatedListener() { ... });

我已经创建了一个小的应用程序，一步一步的描述，以获得当前位置的GPS坐标。

完整的示例源代码是在获取当前位置坐标，城市名称-在Android。

看看它是如何工作的:

All we need to do is add this permission in the manifest file: <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> And create a LocationManager instance like this: LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); Check if GPS is enabled or not. And then implement LocationListener and get coordinates: LocationListener locationListener = new MyLocationListener(); locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 5000, 10, locationListener); Here is the sample code to do so

/*---------- Listener class to get coordinates ------------- */
private class MyLocationListener implements LocationListener {

    @Override
    public void onLocationChanged(Location loc) {
        editLocation.setText("");
        pb.setVisibility(View.INVISIBLE);
        Toast.makeText(
                getBaseContext(),
                "Location changed: Lat: " + loc.getLatitude() + " Lng: "
                    + loc.getLongitude(), Toast.LENGTH_SHORT).show();
        String longitude = "Longitude: " + loc.getLongitude();
        Log.v(TAG, longitude);
        String latitude = "Latitude: " + loc.getLatitude();
        Log.v(TAG, latitude);

        /*------- To get city name from coordinates -------- */
        String cityName = null;
        Geocoder gcd = new Geocoder(getBaseContext(), Locale.getDefault());
        List<Address> addresses;
        try {
            addresses = gcd.getFromLocation(loc.getLatitude(),
                    loc.getLongitude(), 1);
            if (addresses.size() > 0) {
                System.out.println(addresses.get(0).getLocality());
                cityName = addresses.get(0).getLocality();
            }
        }
        catch (IOException e) {
            e.printStackTrace();
        }
        String s = longitude + "\n" + latitude + "\n\nMy Current City is: "
            + cityName;
        editLocation.setText(s);
    }

    @Override
    public void onProviderDisabled(String provider) {}

    @Override
    public void onProviderEnabled(String provider) {}

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {}
}

GoogleSamples有详细的例子使用最新的FusedLocationProviderApi。 不幸的是，被点赞最多的答案都过时了。

按照下面的例子使用FusedLocationProviderApi实现位置服务

https://github.com/googlesamples/android-play-location/tree/master/LocationUpdates

https://github.com/googlesamples/android-play-location/blob/master/LocationUpdates/app/src/main/java/com/google/android/gms/location/sample/locationupdates/MainActivity.java

已经有很多答案，但我想展示最新的方法来获得使用谷歌API的位置，所以新的程序员可以使用新方法:

我已经在我的博客demonuts.com上写了关于当前位置的详细教程，你也可以找到用android studio开发的完整源代码。

首先，把它放到gradle文件中

 compile 'com.google.android.gms:play-services:9.0.2'

然后实现必要的接口

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

声明实例

  private GoogleApiClient mGoogleApiClient;
  private Location mLocation;
  private LocationManager locationManager;
  private LocationRequest mLocationRequest;

把这个放到onCreate()中

 mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

最后，重写必要的方法

 @Override
    public void onConnected(Bundle bundle) {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        } startLocationUpdates();
        mLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
        if(mLocation == null){
            startLocationUpdates();
        }
        if (mLocation != null) {
            double latitude = mLocation.getLatitude();
            double longitude = mLocation.getLongitude();
        } else {
            // Toast.makeText(this, "Location not Detected", Toast.LENGTH_SHORT).show();
        }
    }

    protected void startLocationUpdates() {
        // Create the location request
        mLocationRequest = LocationRequest.create()
                .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
                .setInterval(UPDATE_INTERVAL)
                .setFastestInterval(FASTEST_INTERVAL);
        // Request location updates
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,
                mLocationRequest, this);
        Log.d("reque", "--->>>>");
    }

    @Override
    public void onConnectionSuspended(int i) {
        Log.i(TAG, "Connection Suspended");
        mGoogleApiClient.connect();
    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        Log.i(TAG, "Connection failed. Error: " + connectionResult.getErrorCode());
    }

    @Override
    public void onStart() {
        super.onStart();
        mGoogleApiClient.connect();
    }

    @Override
    public void onStop() {
        super.onStop();
        if (mGoogleApiClient.isConnected()) {
            mGoogleApiClient.disconnect();
        }
    }
    @Override
    public void onLocationChanged(Location location) {

    }

在运行应用程序之前，不要忘记在您的设备中启动GPS。

        locationResult = result;
        if (lm == null)
            lm = (LocationManager) context
                    .getSystemService(Context.LOCATION_SERVICE);

        // Don't start listeners if no provider is enabled.
        if (!gps_enabled && !network_enabled)
            return false;

        if (gps_enabled)

                net_loc = lm
                        .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

            // If there are both values, use the latest one.
            if (gps_loc != null && net_loc != null) {
                if (gps_loc.getTime() > net_loc.getTime())
                    locationResult.gotLocation(gps_loc);
                else
