Answer 1

使用

l.getItemAtPosition(position);

而不是

getListAdapter().getItem(position);

Answer 2

试试这个。替换：

String selectedValue = (String) getListAdapter().getItem(position);

与：

String selectedValue = (String) l.getItemAtPosition(position);

Answer 3

试试这个

getListView().setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {

//do sth.

} });
