Try this way,hope this will help you to solve your problem.

First define position as final in getView() parameter then try to remove list item from you list data holder listDetail using remove method and notify your adapter using notifyDataSetChanged method like :

holder.removeButton.setOnClickListener(new OnClickListener()
{ 
    @Override
    public void onClick(View v)
    {
      listDetail.remove(position);
      notifyDataSetChanged();
      Log.i("Delete Button Clicked",*************************************************");
      Toast.makeText(context, "Delete button Clicked",Toast.LENGTH_LONG).show();
    }
});
