After going through lots of posts and blogs i found this solution it works for me...

声明行变量全局

public View row;

your_list.setOnItemClickListener(new OnItemClickListener() {

    public void onItemClick(AdapterView<?> a, View v,
                        int position, long id) {

    if (row != null) {
        row.setBackgroundResource(R.color.orange);
    }
    row = v;
    v.setBackgroundResource(R.color.transparent_green);
)};
