Spinner type = (Spinner) findViewById(R.id.addcontype);
List<DropDown> typelist = new ArrayList<DropDown>();
......
......
......
        ArrayAdapter<CharSequence> adapter = new ArrayAdapter(this,android.R.layout.simple_spinner_item, typelist);


DropDown typedrp = (DropDown) type.getSelectedItem();就可以正确获取对象！！！

而ListView

private List<AccountBean> list;
......
......
.....
        ListView listview= (ListView) findViewById(R.id.listView1);
        
        ArrayAdapter<CharSequence> adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1, list);

AccountBean bean = listview.getSelectedItem();------------------却始终为NULL！！！！，很郁闷，有人知道是怎么回事？

自己搞了几天找到一个方法可以解决了  AccountBean bean=(AccountBean) listview.getItemAtPosition(arg2);
