Question

在我的getView方法中，当我尝试单击视图的图像按钮时，其相邻视图的图像按钮被单击并且对于其他UI来说是相同的，这意味着它每次都返回错误的视图。我不是能够找出问题所在。

public View getView(final int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    ImageView iv;

您需要在执行任何更改后通知。

holder.like_img.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Toast.makeText(context,holder.heading.getText()+" "+modelList.get(position).getTitle(), Toast.LENGTH_SHORT).show();
            holder.like_img.setImageResource(R.drawable.up_arrow_hover);
            notifyDataSetChanged();//notify after any changes
        }
    });
