构造自己的adapter，在getView中，设置颜色，点击item，刷新listview。

public  void setSelectItem(int selectItem) {

}

private int  selectItem=-1;

}

}

android 自定义adapter extends BaseAdapter，做有自己布局的listView

或：

siteListView.setOnItemClickListener(new OnItemClickListener() {

@Override

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

for(int i=0;i

View v=parent.getChildAt(parent.getCount()-1-i);

if (position == i) {

v.setBackgroundColor(Color.RED);

} else {

v.setBackgroundColor(Color.TRANSPARENT);

}

}

}

});
