メソッドハンドラを停止するには？

Question

方法をこれを停止する方法、私は緯度と経度このメソッドの停止を取得する必要があります。

private final Runnable r = new Runnable() { 
    public void run() { 
     gps = new GPSTracker(MainMaps.this); 
     if (gps.canGetLocation()) { 

      latitude = gps.getLatitude(); 
      longitude = gps.getLongitude(); 

      Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude, Toast.LENGTH_LONG).show(); 
     } 

     final String lat = String.valueOf(gps.getLatitude()); 
     final String longg = String.valueOf(gps.getLongitude()); 

     if (lat.toString() != "0.0" && longg.toString() != "0.0") { 
      LatLng fromPosition = new LatLng(latitude, longitude); 
      LatLng toPosition = new LatLng(-7.782939, 110.367050); 

      md = new GoogleMapV2Direction(); 
      mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.fragment)).getMap(); 

      mMap.getUiSettings().setZoomControlsEnabled(true); 
      mMap.getUiSettings().setCompassEnabled(true); 
      mMap.getUiSettings().setMyLocationButtonEnabled(true); 

      mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(fromPosition, 14)); 

      mMap.addMarker(new MarkerOptions().position(fromPosition) 
        .title("Posisi Anda")); 
      mMap.addMarker(new MarkerOptions().position(toPosition).title("End")); 
      getDirectionMap(fromPosition, toPosition); 

      //handler.removeCallbacks(r); 
      //onStop(); 
      //if (lat.toString() != "0.0" && longg.toString() != "0.0") { 
      // Toast.makeText(getApplicationContext(), "It works===" + lat + "=" + longg, Toast.LENGTH_SHORT).show(); 
       onStop(); 
      // } 
     } 

     Toast.makeText(getApplicationContext(), "It works" + lat + "=" + longg, Toast.LENGTH_SHORT).show(); 
     handler.postDelayed(this, 2000); 
    } 
}; 

protected void onStop() { 
    super.onStop(); 
    handler.removeCallbacksAndMessages(r); 
}

この handler.removeCallbacksAndMessages（null）を試してみてください。
