how to force the listview to refresh its view?

Actually I have tried the following methods:

checkbox_visable=true;
fileList.notifyDataSetChanged();
listview.invalidate();

But it just can not recall the my specified adapter's getview() method for each row:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    convertView=super.getView(position, convertView, parent);
    CheckBox cb=(CheckBox) convertView.findViewById(R.id.item_cb);
    if(checkbox_visable)
    cb.setVisibility(View.INVISIBLE);
    return convertView;
}

So, any idea for me to dynamically change the UI of ListView?

getview is called automaticaly when you scroll down the listview.

your view will be refreshed automaticaly

put a else condition in your code which will set the state of checkbox if the condition is false 

if(checkbox_visable)
            cb.setVisibility(View.INVISIBLE);
else
//what you want the state of the checkbox to be

i think this will work.

Ok then try this 

listview.setAdapter(new FileList(this, R.layout.row, your data));

And in your FileList class make the construstor of your adapter like.  

public FileList(Context context, int textViewResourceId,   String[] objects) {
            super(context, textViewResourceId, objects);
        }

Hope this will help
