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:

class MyLocation {
    Timer timer1;
    LocationManager lm;
    LocationResult locationResult;
    boolean gps_enabled = false;
    boolean network_enabled = false;

    public boolean getLocation(Context context, LocationResult result) {
        // I use LocationResult callback class to pass location value from
        // MyLocation to user code.
        locationResult = result;
        if (lm == null)
            lm = (LocationManager) context
                    .getSystemService(Context.LOCATION_SERVICE);

        // Exceptions will be thrown if the provider is not permitted.
        try {
            gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
        }
        catch (Exception ex) {
        }
        try {
            network_enabled = lm

我希望这对你有所帮助……

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。

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() { ... });

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
