Change image of listview item on click

I am trying to change image of a list item on click.I have tried using view but on using it I am getting multiple items with changed image even though I just click on a single one.I am using a simplecursor adapter and code is same as given in this question:-changing image on listview at runtime in android.

And also I don't want to use a custom adapter.It will be really helpful if someone helps me in solving this problem just through simple adapter.

Current code

  @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // TODO Auto-generated method stub

      /*
      imageView=(ImageView)l.getChildAt(position).findViewById(R.id.PlayPause);


      imageView.setImageResource(R.drawable.pause);

      */
}

1- Do not use get child at when u are directly getting the child view as "View v" in the event.

2- you just need to call invalidate() method on the view once u set the new background resource.

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {

  imageView=((ImageView)v)

  imageView.setImageResource(R.drawable.pause);

  imageView.invalidate();

}

While you should make your list using a simple cursor adapter with an imageview ---- :-

Why not use 

ListView.OnItemClick(OnItemClickListener{})
