listview 打对号效果实现

private void initView() {
    mListView = (ListView) findViewById(R.id.listview);
    favCustomAlertAdapter = new FavIconAlertAdapter(this, icons);
    mListView.setAdapter(favCustomAlertAdapter);
    mListView.setOnItemClickListener(this);
    mListView.post(new Runnable() {
        @Override
        public void run() {
            lastCheckedImg = (ImageView)mListView.getChildAt(0).findViewById(R.id.icon_selected);
            lastCheckedImg.setVisibility(View.VISIBLE);
            mListView.setItemChecked(0, true);
            favCustomAlertAdapter.notifyDataSetChanged();
        }
    });
}

public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    if (lastCheckedImg != null) {
        lastCheckedImg.setVisibility(View.GONE);
    }
    lastCheckedImg = (ImageView) view.findViewById(R.id.icon_selected);
    lastCheckedImg.setVisibility(View.VISIBLE);
    selectedIconId = position;
    favCustomAlertAdapter.notifyDataSetChanged();
}
