problem here, call webview on static position, instead call accordingly array list below.

    if( array_list.get(position).equals("afghanistan")){     intent intent = new intent(search_country.this, country_details.class);                            intent.putextra("header", getstring(r.string.html_afganistan));                                       startactivity(intent); }
