如何获取用户在android上的当前位置？

问题描述：

我一直在尝试使用融合位置API来获取用户的位置，完全像这里所描述的https://developer.android.com/training/location/retrieve-current.html 但我没有得到任何结果。有时它可以工作，但大多数情况下它不工作，并且这只是在虚拟设备上，真正的设备上没有发生。这里是我的MainActivity.java：如何获取用户在android上的当前位置？

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this); 
    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 
     ActivityCompat.requestPermissions(this, 
       new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 
       10); 
     ActivityCompat.requestPermissions(this, 
       new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 
       10); 
     // 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; 
    } 
    Log.v("","the beg"); 
    mFusedLocationClient.getLastLocation() 
      .addOnSuccessListener(this, new OnSuccessListener<Location>() { 
       @Override 
       public void onSuccess(Location location) { 
        // Got last known location. In some rare situations this can be null. 
        if (location != null) { 
         // ... 
         Log.v("", String.valueOf(location.getLatitude())); 
         Log.v("", String.valueOf(location.getLongitude())); 
        } 
       } 
      }); 
    Log.v("","the end"); 
}

} 这我Android.m

@hassanitohajj in'onSucces'方法你有这个吗？ if（location！= null）Geocoder geoCoder = new Geocoder（getBaseContext（），Locale.getDefault（））;''你有一些'...'因此我只是在问。 –

答

首先，定义一个LocationListener的处理位置的变化。

private final LocationListener mLocationListener = new LocationListener() { 
    @Override 
    public void onLocationChanged(final Location location) { 
     //your code here 
    } 
};

然后得到的LocationManager，并要求位置更新

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE); 

    mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 
LOCATION_REFRESH_TIME, 
      LOCATION_REFRESH_DISTANCE, mLocationListener); 
}

最后请确保您所添加的权限的清单，

对于使用基于唯一的网络位置使用一个

对于基于GPS的位置，这一个
