Android : list view item change color on click

I have i listview with 24 text views in it(each one of them present one hour of the day). What i am trying to do is to change background color of the item that i clicked.

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view, int i, long l) {
                View v;
                v = parent.getChildAt(i);
                v.setBackgroundColor(Color.GREEN);

        }
    });

The problem is that when i click on a specific item not only bg color of one item is changed but also some other items change their colors.

i Know that

getChildAt()

does not always get the sam fixed item. I want to know how that should be done so that only the item that is clicked change bg color.
