I handled it in my customized adapter with a dirty approach.

[android-developers] Re: how to deal with button clickevent in a listview?
Please find my working code snippet below:
// get a reference to the ListView
listView = (ListView) findViewById(android.R.id.list);
...
// single click event
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView arg0, View arg1, int arg2,
long arg3) {
My list view works with the customized adapter.
