我有一个多栏列表视图，显示股票列出公司。 代码适用于处理小数据。 （它们适合屏幕，不需要滚动。） 但库存数量不能适合屏幕。发生以下问题。
1。当列表项的详细信息展开并滚动时，也会选择其他项目。 （例如，我扩展3.stock，它选择15.stock和27.stock和39.stock等。）

2. 另一个问题是细节布局。通常它有两个选项卡，但它显示太多选项卡。

public ArrayList<HashMap<String, String>> list;

private String stokNo;
private Context context;

private Object kodTuru;
private boolean clearAlsaDeta;
public static String x;
public StockListAdapter(Activity activity, ArrayList<HashMap<String, String>> list, Context context,String kodTuru, String processNo, String processType, boolean clearAlsaDeta) {
super();
this.activity = activity;

答案 0 :(得分：0)
第一个问题是您没有设置linearLayoutStockDetail的可见性。用于行的android重用视图中的ListView。当您打开第3行的详细视图并滚动底部时 - android重用您的行号3.您为文本字段设置了新值，但不隐藏详细信息视图。
我想，第二个问题是一样的。您没有显示tabDetailSetup方法，但我认为您每次都会添加标签。您需要先清除旧标签。
请记住，当您在适配器中使用convertView时，您可以使用自己的属性获取旧视图，这是您上次设置的。
