带有 ViewHolder 模式的 setOnClickListener 内部适配器失败

Question

我对 OnClickListener() 事件有疑问。

每个按钮视图中每个项目列表的数据或变量给出了不匹配的值。

此外，我通过打印一些日志来测试给出的位置。

根据项目行显示位置不匹配（可能是因为视图回收）

所以，下面是我的适配器实现 class，请帮我识别它。

请给我一个指导和适当的方法来解决这个问题。

MyAdapter.Class

private List<Result> results;

public ManifestAdapter(Context context, int view, List<Result> results) {
    super(context, view, results);
    this.results = results;
    this.context = context;

    sSave = context.getResources().getString(R.string.complete);
    sCancel = context.getResources().getString(R.string.cancel);
    sEditData = context.getResources().getString(R.string.edit_data);
    colorShipping = context.getResources().getColor(R.color.status_shipping);
    colorShippingComplete = context.getResources().getColor(R.color.status_shipping_complete);
    colorShippingIncomplete = context.getResources().getColor(R.color.status_shipping_incomplete);
}

@Override
public Result getItem(int position) {
    return results.get(position);
}



public View getView(final int position, View convertView, ViewGroup parent) {

        int pos = position;
        ViewHolder holder = null;

    if (convertView == null){
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.listitem_manifest, null);

        holder = new ViewHolder();
        holder.front = (RelativeLayout) convertView.findViewById(R.id.front);
        holder.qrcode = (TextView) convertView.findViewById(R.id.qrcode);
        holder.amount = (TextView) convertView.findViewById(R.id.amount);
        holder.customer = (TextView) convertView.findViewById(R.id.customer);
        holder.address = (TextView) convertView.findViewById(R.id.receiverAddress);
        holder.btnTel  = (Button) convertView.findViewById(R.id.receiverTel);
        holder.btnMap = (Button) convertView.findViewById(R.id.district);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    final Result result = getItem(position);


    .....
    .....
    .....


    // setup call
    if (result.getReceiverTel() != null) {
        if (!result.getReceiverTel().equals("")) {
            holder.btnTel.setText(result.getReceiverTel().trim());
            holder.btnTel.setTag(position);
            holder.btnTel.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int pos = (Integer)v.getTag();
                    String uri = "tel:" + getItem(pos).getReceiverTel().trim();
                    Intent iCall = new Intent(Intent.ACTION_DIAL);
                    iCall.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    iCall.setData(Uri.parse(uri));
                    context.startActivity(iCall);
                }
            });
        }
    }
    return convertView;
}

private static class ViewHolder{
    RelativeLayout front;
    TextView qrcode;
    TextView amount;
    TextView customer;
    TextView address;
    Button btnTel;
    Button btnMap;
    int position;
}

请更改此代码。

 // setup call
    if (result.getReceiverTel() != null) {
        if (!result.getReceiverTel().equals("")) {
            holder.btnTel.setText(result.getReceiverTel().trim());
            holder.btnTel.setTag(position);
            holder.btnTel.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int pos = (Integer)v.getTag();
                    String uri = "tel:" + getItem(pos).getReceiverTel().trim();
                    Intent iCall = new Intent(Intent.ACTION_DIAL);
                    iCall.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    iCall.setData(Uri.parse(uri));
                    context.startActivity(iCall);
                }
            });
        }
    }

至

// setup call
  holder.btnTel.setTag(position);

    if (result.getReceiverTel() != null) {
        if (!result.getReceiverTel().equals("")) {
            holder.btnTel.setText(result.getReceiverTel().trim());

            holder.btnTel.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int pos = (Integer)v.getTag();
                    String uri = "tel:" + getItem(pos).getReceiverTel().trim();
                    Intent iCall = new Intent(Intent.ACTION_DIAL);
                    iCall.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    iCall.setData(Uri.parse(uri));
                    context.startActivity(iCall);
                }
            });
        }
    }
