改变图像

Question

目标：我要的是当过我点击列表项中的图像是在

1. 数据库
2. TextView的更改（作为数喜欢增加）
3. 更改图像本身以表示列表项目是喜欢的。

错误：但每当我点击图片它使数据库的变化，并增加相应的TextView的计数。

But it change images of other list items as well than of just clicked item. 

普莱斯帮我下面的代码：

public class PopularTabRowAdapter extends BaseAdapter { 

List<APIDataModel> videoList; 
private Activity activity; 
private static LayoutInflater inflater = null; 
ImageLoader imageloader; 
PopularDataSource datasource; 
int pos; 
ViewHolder holder; 
ListView mListView; 

public PopularTabRowAdapter(Activity activity, 
     List<APIDataModel> videoList, ListView list) { 
    this.activity = activity; 
    this.videoList = videoList; 
    inflater = (LayoutInflater) this.activity 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    imageloader = new ImageLoader(activity); 
    mListView = list; 
    this.datasource = new PopularDataSource(activity); 
} 

@Override 
public int getCount() { 
    // TODO Auto-generated method stub 
    return videoList.size(); 
} 

@Override 
public Object getItem(int arg0) { 
    // TODO Auto-generated method stub 
    return videoList.get(arg0); 
} 

@Override 
public long getItemId(int arg0) { 
    // TODO Auto-generated method stub 
    return videoList.get(arg0).getID(); 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    // TODO Auto-generated method stub 
    View row = convertView; 
    holder = null; 
    pos = position; 
    if (row == null) { 
     row = inflater.inflate(R.layout.popular_tab_custum_row, parent, 
       false); 
     holder = new ViewHolder(); 
     holder.descriptiontxt = (TextView) row 
       .findViewById(R.id.decription_popCustomRow);

     holder.likeImage.setOnClickListener(likeImageListner); 

     holder.numbLike = (TextView) row 
       .findViewById(R.id.noLik_popCustRow); 
     row.setTag(holder); 
    } else { 
     holder = (ViewHolder) row.getTag(); 
    } 

    holder.descriptiontxt.setText(videoList.get(position).getDecription()); 
    holder.listtxt.setText(videoList.get(position).getList()); 
    imageloader.DisplayImage(ApplicationMain 
      .getYouTubeVideoImageURL(videoList.get(position).getURL()), 
      holder.imageView); 
    holder.numbLike.setText(String.valueOf(videoList.get(position) 
      .getNumberOfLikes())); 
    if (videoList.get(position).getLikeStatus() == 1) { 
     holder.likeImage.setImageResource(R.drawable.like_done); 
    } 
    return row; 
}

         vh.numbLike); 
       like.execute(); 
      } 
     } 
    } 
}; 

public ViewHolder getViewHolder(View v) { 
    if (v.getTag() == null) { 
     return getViewHolder((View) v.getParent()); 
    } 
    return (ViewHolder) v.getTag(); 
} 

class HitLike extends AsyncTask<Void, Void, String> { 
    ImageView image;

    TextView text; 

    public HitLike(int position, ImageView image, TextView text) { 
     this.position = position; 
     this.image = image; 
     this.text = text; 
    } 

    @Override

} 

谢谢:)

Answer 1

image.setImageResource(R.drawable.like_done); 

而且由于其设置perticular位置图像变化是getview和有viewholder使用。所以你必须

1）创建用于像位置选择的图像的临时数组。

2）把for循环getview和高达温度的大小，如果getview位置==临时[I]然后

image.setImageResource(R.drawable.like_done); 

其他

image.setImageResource(R.drawable.default); 

完蛋了......
