The adapter that you are currently using is the Default Adapter. However, now you want to modify it's properties. To do so you'll need to implement a custom adapter - an adapter of your own. Just Google Custom ListView Adapter if you don't know how to do that.

And in that custom adapter, there'll be a getView() method and in the getView() method of the custom adapter check if the position of item is same as the selected item. If yes, set background colour.

Sorry but i did not understand :( please see my code and give some suggestion – raman rayat Jun 22 '14 at 10:04
@ramanrayat you need create custom adapter instead of built in adapter, see http://www.vogella.com/tutorials/AndroidListView/article.html#adapterown – Shayan Pourvatan Jun 22 '14 at 10:06

To set color of selected Item use

view.setBackgroundColor(Color.YELLOW);

i.e in your code as

 lv.setOnItemClickListener(new OnItemClickListener(){
        public void onItemClick(AdapterView<?> parent,View view,int position, long id) {

    view.setBackgroundColor(Color.YELLOW);
  // your code

IN your getView method, you have to do some code over there.

int currentPosition=0;



  if (position == currentPosition) {
    convertView.setBackgroundColor(Color.YELLOW);
    } else {
    convertView.setBackgroundColor(Color.YOUR DEFAULT COLOR);
}

//click item code:

convertView.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    currentPosition = position;
                    adapter.notifyDataSetChanged();

                }
            });

how to change color of list item when it is selected in listview?
