if the ListView has focusable items then onClickListener will fire instead of the onItemClickListener. Set items can focus to false

list.setItemsCanFocus(false);

have a look at this thread. Also note there are workarounds for this. But the better choice would be to set items non focusable and use OnItemClickListener, or make them focusable and use an onClickListener on the views

Also, the onClickListener should not be set for the listview. Instead for each listview item in the getView() method

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // ...

    view.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // your code
        }

    });

    return view;
}
