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

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) {}
}

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

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:

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() { ... });

自2020年9月23日起，play-services-location版本17.1.0包含了FusedLocationProviderClient.getCurrentLocation()方法，这是获得当前位置的推荐和直接的方法:

返回设备上的单个当前位置固定。与返回缓存位置的getLastLocation()不同，此方法可能导致设备上的活动位置计算。如果能在合理的时间内(几十秒)确定设备位置，将返回一个新的位置，否则将返回null。
