既然谷歌Play位置服务已经推出，我建议开发者开始使用新的融合位置提供商。你会发现它更容易使用和更准确。请观看谷歌I/O视频《超越蓝点:Android位置的新功能》，由两位创建了新的谷歌Play位置服务API的人制作。

I've been working with location APIs on a number of mobile platforms, and I think what these two guys have done is really revolutionary. It's gotten rid of a huge amount of the complexities of using the various providers. Stack Overflow is littered with questions about which provider to use, whether to use last known location, how to set other properties on the LocationManager, etc. This new API that they have built removes most of those uncertainties and makes the location services a pleasure to use.

I've written an Android app that periodically gets the location using Google Play location services and sends the location to a web server where it is stored in a database and can be viewed on Google Maps. I've written both the client software (for Android, iOS, Windows Phone and Java ME) and the server software (for ASP.NET and SQL Server or PHP and MySQL). The software is written in the native language on each platform and works properly in the background on each. Lastly, the software has the MIT License. You can find the Android client here:

LocationManager是一个类，它提供内置方法来获取最后知道的位置

步骤1:如下所示创建LocationManager对象

导航(导航);

步骤2:添加标准

*Criteria is use for setting accuracy*

Criteria criteria = new Criteria();
int currentapiVersion = android.os.Build.VERSION.SDK_INT;

if (currentapiVersion >= android.os.Build.VERSION_CODES.HONEYCOMB) {

    criteria.setSpeedAccuracy(Criteria.ACCURACY_HIGH);
    criteria.setAccuracy(Criteria.ACCURACY_FINE);
    criteria.setAltitudeRequired(true);
    criteria.setBearingRequired(true);
    criteria.setSpeedRequired(true);

}

步骤3:获取可用的提供商

有两种类型的供应商GPS和网络

 String provider = locationManager.getBestProvider(criteria, true);

第四步:了解最后知道的地点

Location location = locationManager.getLastKnownLocation(provider);

第五步:获取经纬度

如果location对象为空，那么不要尝试调用下面的方法

getLatitude和getLongitude是返回双值的方法

获得位置更新需要大量的代码在Android，你需要照顾

谷歌播放服务可用性检查， 更新谷歌播放服务，如果它是旧的或不可用 对话框创建GoogleApiClient和它的回调连接，断开等。 停止并释放用于位置更新的资源 处理位置权限场景 检查“位置”服务是否开启 获取最后已知位置也不是那么容易 如果在一定时间后没有得到位置，则退回到最后一个已知位置

为了简化所有这些步骤，我创建了android - easylocation(小型android库)，它将照顾所有这些东西，你可以专注于业务逻辑。

所有你需要的是扩展EasyLocationActivity和这个

requestSingleLocationFix(easyLocationRequest);

or

requestLocationUpdates(easyLocationRequest);

签出示例应用程序和步骤需要在这里https://github.com/akhgupta/Android-EasyLocation

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。

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。

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。
