Answer 1

v.setBackgroundColor(Color.parseColor("#88dfdf")); You should not only do that but also have an ArrayList selectedList in which you 'remember' if the item is selected. Then in getView you should 'inspect' that list and put the color accordingly.

 if ( selectedList.get(position) )
      convertView.setBackgroundColor(Color.parseColor("#88dfdf"));
 else      
      convertView.setBackgroundColor(Color.parseColor( normal color ));

Initializing the list in the adapter class:

ArrayList selectedList = new ArrayList();

public CustomAdapter(Context context, List mList)
{
 .........
 int nr = -1;
 while (++nr < mList.size() )
    selectedList.add(false);
 }
}

also add this to getView() function

   public View getView(final int position, View convertView, ViewGroup parent)
    { ...............................
        holder.contact_img.setImageBitmap(ImageHelper.getRoundedCornerBitmap(scaleBitmap, 100));

        if(selectedList.get(position)== true)
        {
          convertView.setBackgroundColor(Color.parseColor("#88dfdf")); 
        }   
        else
        {
          convertView.setBackgroundColor(Color.background_light); 
        }
        return convertView;
    }

also add the following line to your onListItemClick().

protected void onListItemClick(ListView l, View v, int position, long id) 
{
    ..................
    if(mArrayAdapter.selectedList.get(position)==true)
    {
      v.setBackgroundColor(Color.background_light));
      mArrayAdapter.selectedList.set(position,false);
    }
    else
    {
      v.setBackgroundColor(Color.parseColor("#88dfdf"));
      mArrayAdapter.selectedList.set(position,true);
      Toast.makeText(getApplicationContext(), "Items Pos: " + position +"and Name : "+ name, 0).show();
    }

}

and also make selectedList variable to public in CustomAdapter.
