我现在使用listView展示了很多的配置信息，我现在想在点击其中一条的时候填出 alertDialog,点击确认后就删除该条数据，（ ArrayAdapter?，ArrayList，listView 全部删除），我知道在下面的onItemLongClick?方法中参数 arg2? 是选中的序号，但是我不知道如何继续处理下去

listview.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
?

public boolean onItemLongClick(AdapterView<!--?--> arg0, View arg1, int arg2, long arg3) {

????????AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

?????????builder.setCancelable(true);

?????????builder.setTitle("Vuoi davvero cancellare il profilo?");

?????????builder.setPositiveButton("Si", new DialogInterface.OnClickListener() {

????????????????????????????public void onClick(DialogInterface dialog, int which) {

???????????????????????????????????????????// How to remove the selected item?

?????????????????????????????}

????????????????????????});
?

builder.setNegativeButton("Annulla", new DialogInterface.OnClickListener() {

????????public void onClick(DialogInterface dialog, int which) {

????????}

????????});

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

??

????????alert.show();

??

????????profilesAdapter.notifyDataSetChanged();
?
?
?
?

????return true;

??

????}

??

????});
