Google Map如何在裏面添加這段代碼？

Question

如何在這裏結合這段代碼？

duration = directionsList.get（「duration」）; distance = directionsList.get（「distance」）;

protected void onPostExecute(String s) { 
    String[] directionsList; 
    DataParser parser = new DataParser(); 
    directionsList = parser.parseDirections(s); 
    displayDirection(directionsList); 
    MarkerOptions markerOptions = new MarkerOptions(); 
    markerOptions.position(latLng); 
    markerOptions.draggable(true); 
    markerOptions.title("Duration :" + duration); 
    markerOptions.snippet("Distance :" + distance); 

    mMap.addMarker(markerOptions); 

}
