Try this .

public class PersonAdapter extends BaseAdapter { 
private ArrayList<PersonBean> mList; 
private Context mContext; 

public PersonAdapter(ArrayList<PersonBean> list, Context context) { 
    mList = list; 
    mContext = context; 
} 

public void refresh(ArrayList<PersonBean> list) { 
    mList = list; 
    notifyDataSetChanged(); 
}
...

When click 

mAdapter.refresh(mList);

Update your data collection, such as Array or List, and do BaseAdapter.notifyDataSetChanged();
