Android ile internette olan countries.xml URLsindeki XML dosyasını DOM ile parse edip ArrayAdapter kullanarak android.R.layout.simple_list_item_multiple_choice kullanarak listeledim. Bu örneği daha iyi anlamak için Java Crontab XML file Parser JSP Ajax Example bakabilirisniz.
Android ile belirtilen urldeki xml dosyasına bağlanmak için internette erişim izni(AndroidManifest.xml) vermeyi unutmayın.
