使用Gps获取经纬度

没有要求用第三方的定位,我就用Gps了,反正只是上传经纬度到服务器,根据项目我是在service里写的
创建一个service,manifest里记得配置下

public class GpsService extends Service {

private LocationManager mLoactionManager;
protected CompositeDisposable mDisposable = new CompositeDisposable();
protected MaYiApiService apiService = RetrofitHelper.getApiService();
public static final String TAG = "GpsService";
private Location location;
String mToken;
@Override
public void onCreate() {
    Log.d(TAG, "onCreate() executed");
    super.onCreate();
    SharedPreferences sp = getSharedPreferences("userInfo", MODE_PRIVATE);
    mToken = sp.getString("Token", "");
    mLoactionManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    //判断GPS是否正常启动
    if (!mLoactionManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
        CommonUtils.showToast(getApplicationContext(), "请开启GPS导航...");
        //返回开启GPS导航设置界面
        Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
        return;
    }
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Log.d(TAG, "onStartCommand() executed");
    //为获取地理位置信息时设置查询条件
    String bestProvider = mLoactionManager.getBestProvider(getCriteria(), true);
    //获取位置信息
    //如果不设置查询要求，getLastKnownLocation方法传人的参数为LocationManager.GPS_PROVIDER
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        CommonUtils.showToast(getApplicationContext(), "请添加gps权限");
        return flags;
    }
    Location location = mLoactionManager.getLastKnownLocation(bestProvider);
    CommonUtils.showToast(getApplicationContext(),"hah"+location);
    showLOcation(location);
    mLoactionManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,600000,1, locationListener);
    return super.onStartCommand(intent, flags, startId);

}

@Override
public void onDestroy() {
    Log.d(TAG, "onDestroy() executed");
    super.onDestroy();
    mLoactionManager.removeUpdates(locationListener);

}

//位置监听
private LocationListener locationListener = new LocationListener() {

    /**
     * 位置信息变化时触发
     */
    public void onLocationChanged(Location location) {
        showLOcation(location);
        Log.i(TAG, "时间：" + location.getTime());
        Log.i(TAG, "经度：" + location.getLongitude());
        Log.i(TAG, "纬度：" + location.getLatitude());
        Log.i(TAG, "海拔：" + location.getAltitude());
    }

    /**
     * GPS状态变化时触发
     */
    public void onStatusChanged(String provider, int status, Bundle extras) {
        switch (status) {
            //GPS状态为可见时
            case LocationProvider.AVAILABLE:
                Log.i(TAG, "当前GPS状态为可见状态");
                break;
            //GPS状态为服务区外时
            case LocationProvider.OUT_OF_SERVICE:
                Log.i(TAG, "当前GPS状态为服务区外状态");
                break;
            //GPS状态为暂停服务时
            case LocationProvider.TEMPORARILY_UNAVAILABLE:
                Log.i(TAG, "当前GPS状态为暂停服务状态");
                break;
        }
    }

    /**
     * GPS开启时触发
     */
    public void onProviderEnabled(String provider) {
        if (ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            CommonUtils.showToast(getApplicationContext(), "请添加gps权限");
            return;
        }
        Location location = mLoactionManager.getLastKnownLocation(provider);
        showLOcation(location);
    }

    /**
     * GPS禁用时触发
     */
    public void onProviderDisabled(String provider) {
        showLOcation(null);
    }


};

    private void showLOcation(Location location){
        if (location!=null){
        PostInfoBean.PostInfoGps postInfoGps = new PostInfoBean.PostInfoGps();
        postInfoGps.setLat((float) location.getLatitude());
        postInfoGps.setLon((float)location.getLongitude());
        String postInfoStr = GsonSingle.getInstance().toJson(postInfoGps);
        RequestBody body = RequestBody.create(MediaType.parse("application/json"), postInfoStr);
        //联网上传经纬度
        mDisposable.add(apiService.getGps(mToken,body).subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Consumer() {
                    @Override
                    public void accept(@NonNull Messagebean s) throws Exception {

                    }
                }, new Consumer() {
                    @Override
                    public void accept(@NonNull Throwable throwable) throws Exception {

                    }
                }));
        }else{
            CommonUtils.showToast(getApplicationContext(),"没有获取到经纬度");
        }
    }



@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

/**
 * 返回查询条件
 * @return
 */
private Criteria getCriteria(){
    Criteria criteria=new Criteria();
    //设置定位精确度 Criteria.ACCURACY_COARSE比较粗略，Criteria.ACCURACY_FINE则比较精细
    criteria.setAccuracy(Criteria.ACCURACY_FINE);
    //设置是否要求速度
    criteria.setSpeedRequired(false);
    // 设置是否允许运营商收费
    criteria.setCostAllowed(false);
    //设置是否需要方位信息
    criteria.setBearingRequired(false);
    //设置是否需要海拔信息
    criteria.setAltitudeRequired(false);
    // 设置对电源的需求
    criteria.setPowerRequirement(Criteria.POWER_LOW);
    return criteria;
}
}

在需要启动的时候调用
Intent startIntent = new Intent(context, GpsService.class);
startService(startIntent);
不用的就停止
Intent startIntent = new Intent(context, GpsService.class);
stopService(startIntent);
