如何使用按钮来改变onclicklistener列表视图

Question

的行内TextView的文本，我有以下AdapterClass：

public class ItemListAdapter extends BaseAdapter { 

//My private ViewHolder class 
private static class ViewHolder 
{ 
    ImageButton plusButton; 
    ImageButton minusButton; 
    TextView item_name, item_price, item_quantity, item_count; 
    NetworkImageView networkImageView; 
} 
private static final String TAG = KindHeart.class.getSimpleName(); 
private Activity activity; 
private LayoutInflater inflater; 
private ArrayList<Items> itemsArrayList; 
ImageLoader imageLoader = AppController.getInstance().getImageLoader(); 
int count = 0; 

public ItemListAdapter(Activity activity, ArrayList<Items> itemsArrayList) { 
    this.activity = activity; 
    this.itemsArrayList = itemsArrayList; 
} 

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

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

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

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    final ViewHolder viewHolder; 
    if (inflater == null) 
     inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    if (imageLoader == null) 
     imageLoader = AppController.getInstance().getImageLoader(); 


    if (convertView == null) 
    { 
     convertView = inflater.inflate(R.layout.items_row, null); 
     viewHolder = new ViewHolder(); 
     viewHolder.networkImageView = (NetworkImageView)convertView.findViewById(R.id.networkImageView); 
     viewHolder.item_name = (TextView)convertView.findViewById(R.id.item_name); 
     viewHolder.item_price = (TextView)convertView.findViewById(R.id.item_price); 
     viewHolder.item_quantity = (TextView)convertView.findViewById(R.id.item_quantity); 
     viewHolder.item_count = (TextView)convertView.findViewById(R.id.item_count); 
     viewHolder.item_count.setTag(position); 
     viewHolder.plusButton = (ImageButton)convertView.findViewById(R.id.plusButton); 
     viewHolder.plusButton.setTag(position); 
     viewHolder.minusButton = (ImageButton)convertView.findViewById(R.id.minusButton); 
     viewHolder.minusButton.setTag(position); 
     convertView.setTag(viewHolder); 
    } 
    else 
    { 
     viewHolder = (ViewHolder)convertView.getTag(); 
    } 
    //Setting item_data in item_row 
    //networkImageView.setImageUrl(item.getImage(),imageLoader); 
    Items item = itemsArrayList.get(position); 
    viewHolder.networkImageView.setImageUrl("", imageLoader); 
    viewHolder.item_name.setText(item.getName()); 
    viewHolder.item_price.setText("₹" + item.getPrice()); 
    viewHolder.item_quantity.setText(item.getQuantity()+"gm"); 
    viewHolder.plusButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      count++; 
      viewHolder.item_count.setText(count + ""); 
      notifyDataSetChanged(); 
     } 
    }); 
    /* 
    viewHolder.minusButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      if (a[position] > 0) 
       a[position]--; 
      //viewHolder.item_count.setText(a[position]); 
      //notifyDataSetChanged(); 
     } 
    });*/ 


    return convertView; 
} 

}

我想的是，当我点击加号按钮，我对应的文本视图'item_count'被更新。一切都很顺利，但是当我点击加号按钮时，列表中的多个文本视图被更新。我分享的截图：

1st half of list

2nd half of list

R.id.items_row：

我试图使列表就像PepperTap应用已经得到了。请帮助我。你可以参考PepperTap应用程序来看看。 感谢和问候。

Answer 2

刚上的onClick添加的setText的OnBindViewHolder 希望它能帮助:)

公共无效onBindViewHolder（DisplayTrainsAdapter.ViewHolder viewHolder，最终诠释位置）{

viewHolder.tvSrc.setText(mDataset.get(position).strSrc); 
viewHolder.tvSrc.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     //Main Trick 
     viewHolder.tvSrc.setText("Your text"); 
    } 
}); 
}
