因为我不喜欢其他答案中的一些代码，下面是我的简单解决方案。这个解决方案意味着在活动或服务中可用来跟踪位置。它确保它永远不会返回太陈旧的数据，除非您显式地请求陈旧的数据。它既可以在回调模式下运行，以便在我们收到更新时获得更新，也可以在轮询模式下运行，以便轮询最新的信息。

通用LocationTracker接口。允许我们有多种类型的位置跟踪器，并轻松插入适当的一个:

package com.gabesechan.android.reusable.location;

import android.location.Location;

public interface LocationTracker {
    public interface LocationUpdateListener{
        public void onUpdate(Location oldLoc, long oldTime, Location newLoc, long newTime);
    }

    public void start();
    public void start(LocationUpdateListener update);

    public void stop();

    public boolean hasLocation();

    public boolean hasPossiblyStaleLocation();

    public Location getLocation();

    public Location getPossiblyStaleLocation();

}

ProviderLocationTracker——这个类将跟踪GPS或NETWORK的位置。

package com.gabesechan.android.reusable.location;

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;

public class ProviderLocationTracker implements LocationListener, LocationTracker {

    // The minimum distance to change Updates in meters
    private static final long MIN_UPDATE_DISTANCE = 10; 

    // The minimum time between updates in milliseconds
    private static final long MIN_UPDATE_TIME = 1000 * 60; 

    private LocationManager lm;

    public enum ProviderType{
        NETWORK,
        GPS
    };    
    private String provider;

    private Location lastLocation;
    private long lastTime;

    private boolean isRunning;

    private LocationUpdateListener listener;

    public ProviderLocationTracker(Context context, ProviderType type) {
        lm = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
        if(type == ProviderType.NETWORK){
            provider = LocationManager.NETWORK_PROVIDER;
        }
        else{
            provider = LocationManager.GPS_PROVIDER;
        }
    }

    public void start(){
        if(isRunning){
            //Already running, do nothing
            return;
        }

        //The provider is on, so start getting updates.  Update current location
        isRunning = true;
        lm.requestLocationUpdates(provider, MIN_UPDATE_TIME, MIN_UPDATE_DISTANCE, this);
        lastLocation = null;
        lastTime = 0;
        return;
    }

    public void start(LocationUpdateListener update) {
        start();
        listener = update;

    }


    public void stop(){
        if(isRunning){
            lm.removeUpdates(this);
            isRunning = false;
            listener = null;
        }
    }

    public boolean hasLocation(){
        if(lastLocation == null){
            return false;
        }
        if(System.currentTimeMillis() - lastTime > 5 * MIN_UPDATE_TIME){
            return false; //stale
        }
        return true;
    }

    public boolean hasPossiblyStaleLocation(){
        if(lastLocation != null){
            return true;
        }
        return lm.getLastKnownLocation(provider)!= null;
    }

    public Location getLocation(){
        if(lastLocation == null){
            return null;
        }
        if(System.currentTimeMillis() - lastTime > 5 * MIN_UPDATE_TIME){
            return null; //stale
        }
        return lastLocation;
    }

    public Location getPossiblyStaleLocation(){
        if(lastLocation != null){
            return lastLocation;
        }
        return lm.getLastKnownLocation(provider);
    }

    public void onLocationChanged(Location newLoc) {
        long now = System.currentTimeMillis();
        if(listener != null){
            listener.onUpdate(lastLocation, lastTime, newLoc, now);
        }
        lastLocation = newLoc;
        lastTime = now;
    }

    public void onProviderDisabled(String arg0) {

    }

    public void onProviderEnabled(String arg0) {

    }

    public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
    }
}

这是FallbackLocationTracker，它将通过GPS和NETWORK进行跟踪，并使用任何更准确的位置。

package com.gabesechan.android.reusable.location;

import android.content.Context;
import android.location.Location;
import android.location.LocationManager;

public class FallbackLocationTracker  implements LocationTracker, LocationTracker.LocationUpdateListener {


    private boolean isRunning;

    private ProviderLocationTracker gps;
    private ProviderLocationTracker net;

    private LocationUpdateListener listener;

    Location lastLoc;
    long lastTime;

    public FallbackLocationTracker(Context context) {
        gps = new ProviderLocationTracker(context, ProviderLocationTracker.ProviderType.GPS);
        net = new ProviderLocationTracker(context, ProviderLocationTracker.ProviderType.NETWORK);
    }

    public void start(){
        if(isRunning){
            //Already running, do nothing
            return;
        }

        //Start both
        gps.start(this);
        net.start(this);
        isRunning = true;
    }

    public void start(LocationUpdateListener update) {
        start();
        listener = update;
    }


    public void stop(){
        if(isRunning){
            gps.stop();
            net.stop();
            isRunning = false;
            listener = null;
        }
    }

    public boolean hasLocation(){
        //If either has a location, use it
        return gps.hasLocation() || net.hasLocation();
    }

    public boolean hasPossiblyStaleLocation(){
        //If either has a location, use it
        return gps.hasPossiblyStaleLocation() || net.hasPossiblyStaleLocation();
    }

    public Location getLocation(){
        Location ret = gps.getLocation();
        if(ret == null){
            ret = net.getLocation();
        }
        return ret;
    }

    public Location getPossiblyStaleLocation(){
        Location ret = gps.getPossiblyStaleLocation();
        if(ret == null){
            ret = net.getPossiblyStaleLocation();
        }
        return ret;
    }

    public void onUpdate(Location oldLoc, long oldTime, Location newLoc, long newTime) {
        boolean update = false;

        //We should update only if there is no last location, the provider is the same, or the provider is more accurate, or the old location is stale
        if(lastLoc == null){
            update = true;
        }
        else if(lastLoc != null && lastLoc.getProvider().equals(newLoc.getProvider())){
            update = true;
        }
        else if(newLoc.getProvider().equals(LocationManager.GPS_PROVIDER)){
            update = true;
        }
        else if (newTime - lastTime > 5 * 60 * 1000){
            update = true;
        }

        if(update){
            if(listener != null){
                listener.onUpdate(lastLoc, lastTime, newLoc, newTime);                  
            }
            lastLoc = newLoc;
            lastTime = newTime;
        }

    }
}

由于两者都实现了LocationTracker接口，您可以很容易地改变使用哪一个的想法。要在轮询模式下运行类，只需调用start()。要在更新模式下运行它，请调用start(Listener)。

还可以看看我关于代码的博客文章

通过-获取gps位置

LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);

LocationListener locationListener = new LocationListener() 
{

            @Override
            public void onStatusChanged(String provider, int status, Bundle extras) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onProviderEnabled(String provider) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onProviderDisabled(String provider) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onLocationChanged(Location location) {
                // TODO Auto-generated method stub
                double latitude = location.getLatitude();
                double longitude = location.getLongitude();
                double speed = location.getSpeed(); //spedd in meter/minute
                speed = (speed*3600)/1000;      // speed in km/minute               Toast.makeText(GraphViews.this, "Current speed:" + location.getSpeed(),Toast.LENGTH_SHORT).show();
            }
        };

        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

}

你需要使用latest/最新的

GoogleApiClient Api

基本上你需要做的是:

private GoogleApiClient mGoogleApiClient;
mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(LocationServices.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

然后

@Override
    public void onConnected(Bundle connectionHint) {
        mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                mGoogleApiClient);
        if (mLastLocation != null) {
            mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
            mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
        }
    }

为最准确可靠的定位。请看我的帖子:

https://stackoverflow.com/a/33599228/2644905

不要使用LocationListener，它是不准确的，有延迟响应。老实说，这更容易实现。 请阅读文档:https://developers.google.com/android/reference/com/google/android/gms/common/api/GoogleApiClient

到2020年下半年，有一种更简单的方法来做到这一点。

不包括请求权限(我将在底部包含更新的开发人员)，下面是代码。

记住，你至少需要在你的依赖项中包含这个版本的库(在应用程序的build.gradle中):

implementation 'com.google.android.gms:play-services-location:17.1.0'

．.． 当然还有你清单上的准许

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Kotlin(首先是设置):

private val fusedLocationClient: FusedLocationProviderClient by lazy {
    LocationServices.getFusedLocationProviderClient(applicationContext)
}

private var cancellationTokenSource = CancellationTokenSource()

然后是主代码(FINE_LOCATION):

private fun requestCurrentLocation() {
    // Check Fine permission
    if (ActivityCompat.checkSelfPermission(
            this,
            Manifest.permission.ACCESS_FINE_LOCATION) ==
        PackageManager.PERMISSION_GRANTED) {

        // Main code
        val currentLocationTask: Task<Location> = fusedLocationClient.getCurrentLocation(
            PRIORITY_HIGH_ACCURACY,
            cancellationTokenSource.token
        )

        currentLocationTask.addOnCompleteListener { task: Task<Location> ->
            val result = if (task.isSuccessful) {
                val result: Location = task.result
                "Location (success): ${result.latitude}, ${result.longitude}"
            } else {
                val exception = task.exception
                "Location (failure): $exception"
            }

            Log.d(TAG, "getCurrentLocation() result: $result")
        }
    } else {
        // Request fine location permission (full code below).
}

如果你更喜欢Java，它看起来像这样:

public class JavaVersion extends AppCompatActivity {

    private final String TAG = "MainActivity";

    // The Fused Location Provider provides access to location APIs.
    private FusedLocationProviderClient fusedLocationClient;

    // Allows class to cancel the location request if it exits the activity.
    // Typically, you use one cancellation source per lifecycle.
    private final CancellationTokenSource cancellationTokenSource = new CancellationTokenSource();

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        fusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
    }
    ...
    
    private void requestCurrentLocation() {
        Log.d(TAG, "requestCurrentLocation()");
        // Request permission
        if (ActivityCompat.checkSelfPermission(
                this,
                Manifest.permission.ACCESS_FINE_LOCATION) ==
                PackageManager.PERMISSION_GRANTED) {
            
            // Main code
            Task<Location> currentLocationTask = fusedLocationClient.getCurrentLocation(
                    PRIORITY_HIGH_ACCURACY,
                    cancellationTokenSource.getToken()
            );

            currentLocationTask.addOnCompleteListener((new OnCompleteListener<Location>() {
                @Override
                public void onComplete(@NonNull Task<Location> task) {

                    String result = "";

                    if (task.isSuccessful()) {
                        // Task completed successfully
                        Location location = task.getResult();
                        result = "Location (success): " +
                                location.getLatitude() +
                                ", " +
                                location.getLongitude();
                    } else {
                        // Task failed with an exception
                        Exception exception = task.getException();
                        result = "Exception thrown: " + exception;
                    }

                    Log.d(TAG, "getCurrentLocation() result: " + result);
                }
            }));
        } else {
            // TODO: Request fine location permission
            Log.d(TAG, "Request fine location permission.");
        }
    }
    ...
}

的参数:

PRIORITY类型是自解释的。(其他选项是PRIORITY_BALANCED_POWER_ACCURACY, PRIORITY_LOW_POWER和PRIORITY_NO_POWER。) CancellationToken——如果用户导航离开Activity，这个token允许你取消请求。

操作(Kotlin):

override fun onStop() {
    super.onStop()
    // Cancels location request (if in flight).
    cancellationTokenSource.cancel()
}

就是这样。

现在，这使用FusedLocationProviderClient，这是一个谷歌播放服务api。

这意味着这适用于所有带有谷歌Play Store的Android设备(数量很多)。然而，对于在中国没有Play Store的设备来说，这是行不通的，所以要考虑到这一点。

对于这方面的开发人员来说，如果用户还没有批准，则需要请求精细(或粗略)位置权限，因此在上面的代码中，我将请求位置权限。

下面是完整的代码(在Kotlin中)。

我希望这对你有所帮助(让你的生活更轻松一点)!

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

如果你正在为Android创建新的位置项目，你应该使用新的谷歌Play位置服务。它更准确，使用起来更简单。

几年来，我一直致力于一个开源的GPS跟踪器项目，GpsTracker。我最近更新了它，以处理来自Android、iOS、Windows Phone和Java ME手机的定期更新。它功能齐全，可以满足您的需要，并且拥有MIT许可证。

GpsTracker中的Android项目使用了新的谷歌播放服务，还有两个服务器堆栈(ASP。NET和PHP)来让你追踪这些手机。
