支持Android的GPS

我尝试连接位置服务而不使用位置设置，但任何时候我运行项目时都会出现错误。我提到下面的代码支持Android的GPS

public class Practice2 extends Activity implements LocationListener{ 
private static final String TAG = "Profile"; 
protected static final int REQUEST_CHECK_SETTINGS = 0x1; 

protected LocationManager locationManager; 
protected LocationListener locationListener; 
protected Context context; 



protected boolean gps_enabled,network_enabled; 

protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
setContentView(R.layout.practice2); 

locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, (android.location.LocationListener) this); 

} 


@Override 
public void onLocationChanged(Location location) { 

} 

public void onProviderDisabled(String provider) { 
Log.d("Latitude","disable"); 
} 

public void onProviderEnabled(String provider) { 
Log.d("Latitude","enable"); 
} 

public void onStatusChanged(String provider, int status, Bundle extras) { 
Log.d("Latitude","status"); 
}}

请让我带一个示例编码如何可以启用位置服务，而无需导航到位置服务。

这是我写的logcat

您将需要工具LocationListener的，你是铸造这LocationListener的。 locationManager.requestLocationUpdates（LocationManager.GPS_PROVIDER，0，（android.location.LocationListener）this）; – Lavakush

提供此文件的完整代码。 –

我做了所有这些，但同样的错误， – user3669034
