Use this way:-- This code will help to u for change the color of selected Item of listview

Just take one variable Called SELECTED_POSITION=-1 in your activity;

When u clicked any item in ListView the position which is clicked that u will get by this code 

productList.setOnItemClickListener(new OnItemClickListener() {


        @Override
        public void onItemClick(AdapterView<?> parent, View view,int position, long id) {

            SELECTED_POSITION =position;
        }
     });

then implement Custom Adapter Class in which @override method is there is called getView(...)

@Override
public View getView(int position, View convertView, ViewGroup parent) 
{
    ViewHolder holder = null;
    if (convertView == null) {
        LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = vi.inflate(R.layout.row_adptr, null);
        holder = new ViewHolder();
        holder.text = (TextView) convertView
                .findViewById(R.id.adapterText1);
        holder.chkbox = (CheckBox) convertView
                .findViewById(R.id.checkBox1);
        holder.imageview = (ImageView) convertView
                .findViewById(R.id.imageView1);
        convertView.setTag(holder);          

    } else {
        holder = (ViewHolder) convertView.getTag();
    }

       // this is the code when selected item stay at one position 
       if(position ==SELECTED_POSITION)
       {
            // set your selected Item Color
             convertView.setBackgroundColor(Color.WHITE);
       }
        else
       {   // set your unselected Item Color
               convertView.setBackgroundColor(Color.CYAN);
       } 

     ....Extra code of set value...
 }
