如何在没有"实现LocationListener"的情况下使用LocationListener？

Question

我终于到达了一个应用程序,它获得了用户的GPS位置,但我实现了LocationListener.它工作正常,但我需要这样做而不实现它,因为我必须做一个不实现方法的类.

我搜索了很多教程并检查了很多网站,我尝试将我的代码转换为不实现LocationListener,但我不能这样做,我测试的每件事都破坏了我的应用程序并停止获取用户的GPS位置.

请问,如果有专家对此可以转换我的代码而不使用"实现LocationListener"我将被授予他

这是要转换的代码:

public class GpsMiniActivity extends Activity implements LocationListener{

private LocationManager mLocMgr;
private TextView tv1;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    FrameLayout rl = new FrameLayout(this.getApplicationContext());
    LinearLayout ll= new LinearLayout(this.getApplicationContext());
    ll.setOrientation(LinearLayout.VERTICAL);

    setContentView(rl);
    rl.addView(ll);

    tv1=new TextView(getApplicationContext());
    ll.addView(tv1);

    //setContentView(R.layout.main);
    mLocMgr = (LocationManager) getSystemService(LOCATION_SERVICE);
    mLocMgr.requestLocationUpdates(LocationManager.GPS_PROVIDER,
            500, 0, this);
}
@Override
public void onLocationChanged(Location location) {
    tv1.setText("Lat " +   location.getLatitude() + " Long " + location.getLongitude());
}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
}

public class GpsMiniActivity extends Activity {

private LocationManager mLocMgr;
private TextView tv1;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    FrameLayout rl = new FrameLayout(this.getApplicationContext());
    LinearLayout ll= new LinearLayout(this.getApplicationContext());
    ll.setOrientation(LinearLayout.VERTICAL);

    setContentView(rl);
    rl.addView(ll);

    tv1=new TextView(getApplicationContext());
    ll.addView(tv1);

    //setContentView(R.layout.main);
    mLocMgr = (LocationManager) getSystemService(LOCATION_SERVICE);
    mLocMgr.requestLocationUpdates(LocationManager.GPS_PROVIDER,
            500, 0, ll);
}
}
private LocationListener ll = new LocationListener(){
public void onLocationChanged(Location location) {
    tv1.setText("Lat " +   location.getLatitude() + " Long " + location.getLongitude());
}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
}
}
