android - customAdapter 的 textView 值在 android 中执行 clickEvent 时发生变化

Question

我做了一个自定义的 ListAdapter，我在那个适配器中绑定(bind)了一些 textView，我想执行适配器的 textview 的点击事件，并将一些值传递给另一个 Activity ，我试过如下，但事情是我得到当我的 ListView 被加载时，与当前 textView 不同的值，所以我只需要被点击的 textView 的值。但目前我在屏幕上获得了大部分显示的 ListView 的按钮，请帮助我，因为 y 代码如下:

适配器.java

public class OrderAdapter extends BaseAdapter {
    public ArrayList<HashMap<String, String>> orderArray;
    private Context mContext;
    String statusCode, status, orderId;
    Intent i;

    public OrderAdapter(Context paramContext, ArrayList<HashMap<String, String>> productList) {
        this.mContext = paramContext;
        this.orderArray = productList;
    }

    public int getCount() {
        return this.orderArray.size();
    }

    public Object getItem(int paramInt) {
        return Integer.valueOf(paramInt);
    }

    public long getItemId(int paramInt) {
        return paramInt;
    }

    @SuppressWarnings("static-access")
    public View getView(int paramInt, View paramView, ViewGroup paramViewGroup) {
        LayoutInflater localLayoutInflater = (LayoutInflater) this.mContext.getSystemService("layout_inflater");
        Viewholder localViewholder = null;
        if (paramView == null) {
            paramView = localLayoutInflater.inflate(R.layout.raw_order, paramViewGroup, false);
            localViewholder = new Viewholder();

            localViewholder.orderNo = ((TextView) paramView.findViewById(R.id.tv_order_no));
            localViewholder.date = ((TextView) paramView.findViewById(R.id.tv_date));
            localViewholder.status = ((TextView) paramView.findViewById(R.id.tv_stats));
            localViewholder.proName = ((TextView) paramView.findViewById(R.id.tv_proname));
            localViewholder.amount = ((TextView) paramView.findViewById(R.id.tv_amt));
            localViewholder.link = ((TextView) paramView.findViewById(R.id.tv_link));

            paramView.setTag(localViewholder);

        } else {
            localViewholder = new Viewholder();
            localViewholder = (Viewholder) paramView.getTag();
        }
        System.out.println("::::::::::::::array indexes::::::::::::" + orderArray.get(paramInt));
        System.out.println(":::::::::::::::;;status::::::::::::::::::::;;" + orderArray.get(paramInt).get(Const.TAG_ORDER_STATUS_ID));
        statusCode = orderArray.get(paramInt).get(Const.TAG_ORDER_STATUS_ID);
        getStatus(statusCode);
        orderId = orderArray.get(paramInt).get(Const.TAG_ORDER_ID);
        localViewholder.orderNo.setText("Order no.:" + orderId);

        localViewholder.date.setText(orderArray.get(paramInt).get(Const.TAG_DATE_ADDED));
        localViewholder.status.setText(status);
        localViewholder.proName.setText(orderArray.get(paramInt).get(Const.TAG_PRODUCT_NAME));
        localViewholder.amount.setText(orderArray.get(paramInt).get(Const.TAG_TOTAL));
        if (statusCode.equals("1") || statusCode.equals("2") || statusCode.equals("7") || statusCode.equals("11")) {
            localViewholder.link.setVisibility(View.VISIBLE);
            localViewholder.link.setText("Review and pay");
            System.out.println(":::::::::::::::inside IF::::::::::::::::::;" + orderId);
        } else {
            System.out.println(":::::::::::::::inside else::::::::::::::::::;" + orderId);
            localViewholder.link.setVisibility(View.INVISIBLE);
        }
        localViewholder.link.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent i = new Intent(mContext, OrderWebViewActivity.class);
                i.putExtra(Const.TAG_ORDER_ID, orderId);
                mContext.startActivity(i);
            }
        });

        return paramView;

    }

    static class Viewholder {

        TextView orderNo;
        TextView date;
        TextView status;
        TextView proName;
        TextView amount;
        TextView link;

    }

    /*
     * status based Links...........!!!!!
     */


    }
}

您需要删除以下 2 个内容

1. 从您的 localViewholder

   中移除静态变量

2. 在 getTag() 时，您再次创建 localViewholder 的新实例，将其删除。
