      return(row);

} 

Answer 1

使用

l.getItemAtPosition(position); 

，而不是

getListAdapter().getItem(position); 

Answer 2

與此嘗試。替換：

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

有了：

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

Answer 3

試試這個

getListView().setOnItemClickListener(new OnItemClickListener() { 

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

//do sth. 

} }）;
