ArrayList을 String[] 형으로 변환

AlertDialog 에 ArrayList 값을 뿌려주기 위해..

String[] items = resultItemData.toArray(new String[resultItemData.size()]);

AlertDialog.Builder builder = new AlertDialog.Builder(SiteInfoMap.this); builder.setTitle("선택"); builder.setItems(items, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int item) { Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();

 }

});

AlertDialog alert = builder.create(); alert.show();
