SeekBar里面的ListView回收问题

Question

我在ListView中遇到了SeekBar和TextView的问题。当用户移动SeekBar时，它会很好用（当SeekBar进度在同一行中发生变化时，它会更新相应行中的TextView）。

问题在于ListView回收视图。快速滚动时，所有行都变得疯狂。我在ViewHolder中找到了一些解决方案并试图实现它，但我没有成功（它仍然无法工作）。

这是扩展BaseAdapter的自定义适配器

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.SeekBar;
import android.widget.SeekBar.OnSeekBarChangeListener;
import android.widget.TextView;

public class SimpleListAdapter extends BaseAdapter{

    //private TextView tvDrink, tvPrice, tvQuantity;
    //private ImageView imgV;
    //private SeekBar seeker;
    private List<Menu> list;

    private ViewHolder holder;
    private LayoutInflater inflater;
    private Activity activity;

    public SimpleListAdapter(Activity a, ArrayList<Menu> list){
        this.activity = a;
        this.list = list;
        inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        return list.size();
    }

    @Override
    public Object getItem(int position) {
        return position;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View v = convertView;
        if(v == null){
            v = inflater.inflate(R.layout.simple_item, null);
            holder = new ViewHolder();
            holder.tvDrink = (TextView) v.findViewById(R.id.drink);
            holder.tvPrice = (TextView) v.findViewById(R.id.price);
            holder.seeker = (SeekBar) v.findViewById(R.id.seek);
            //imgV = (ImageView) v.findViewById(R.id.image);

            v.setTag(holder);
        }else{
            holder = (ViewHolder) v.getTag();
        }
        Menu m = list.get(position);

        holder.tvDrink.setText(m.getDrink());
        holder.tvPrice.setText(m.getPrice());

        holder.seeker.setOnSeekBarChangeListener(new SeekerListener());

        return v;
    }

    private class SeekerListener implements OnSeekBarChangeListener{


        @Override
        public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) {


                View view = (View) seekBar.getParent().getParent();
                holder.tvQuantity = (TextView) view.findViewById(R.id.quantitiy);
                holder.tvQuantity.setText(""+progress);

            //  seeker.setTag(tvQuantity);
            //  tvQuantity.setTag(seeker);

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            //notifyDataSetChanged();

        }

    }

    private class ViewHolder{
        TextView tvDrink;
        TextView tvPrice;
        TextView tvQuantity;
        SeekBar seeker;
    }
}

P.S。稍后我将添加ImageView，但由于我使用外部库来处理listview中的图像缓存，所以我没有遇到任何问题。
