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

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<parent.getCount();i++){
            View v=parent.getChildAt(parent.getCount()-1-i);
            if (position == i) {
                v.setBackgroundColor(Color.RED);
            } else {
                v.setBackgroundColor(Color.TRANSPARENT);
            }
        }
    }
});

这样的都不会达到理想的效果,点击某页的某一项,颜色改变,其他页也会有一项的颜色跟着改变的。  回复  更多评论
