我的列表视图包含一个图像和一些文本视图;有两个包含价格和特价的textiview,如果特价为0,则只设置价格textview和特价让它为空,但特价>0比设置的价格值以及特价,第一次一切顺利但是当我滚动列表视图时,空白文本视图设置为虚拟值enter code here
这是我的 getView 方法代码。
@Override
public View getView(final int position, View convertView, ViewGroup parent){
//public View getView(int position, View convertView, ViewGroup parent) {
/*View vi = convertView;
if (convertView == null)
{
vi = inflater.inflate(R.layout.list_row, null);
}
*/
int pos=position;
if (convertView == null) {
convertView = inflater.inflate(R.layout.list_row, null);
