我需要做一个ListView，在每个项目中它最多可以显示9张图片。所以我认为带有GirdView的ListView可能有效。但问题是，当我第一次从服务器获取图像时，它没有运行。但是当我滚动（它没有屏幕）并向后滚动时。图像消失但TextView没有错。我能找到原因。
这是GirdView的BaseAdapter：
class NoScrollGridAdapter extends BaseAdapter{
private Context mContext;
private ArrayList<String> items;
public NoScrollGridAdapter(Context ctx, ArrayList<String> items) {
this.mContext = ctx;
this.items = items;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
Log.v("getCount",items.size()+"");
return items.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return items.get(position);
};
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder2 holder2;
//View view = View.inflate(mContext, R.layout.image_item, null);
if (convertView == null) {
holder2 = new ViewHolder2();
convertView = View.inflate(mContext, R.layout.image_item, null);
holder2.item= (NetworkImageView) convertView.findViewById(R.id.itemImage);
convertView.setTag(holder2);
}
else{
holder2 = (ViewHolder2) convertView.getTag();
}
String dataString=items.get(position);
holder2.item.setDefaultImageResId(R.drawable.moren);
holder2.item.setErrorImageResId(R.drawable.moren);
ImageLoader imageLoader = new ImageLoader(Merchant_main.BBQueue, localStore.storeCache);
holder2.item.setImageUrl(dataString,imageLoader);
return convertView;
}
}
static class ViewHolder2 {
private NetworkImageView item;
}
在listView的BaseAdapter中，在getView（）中我绑定了这个
中的adpter NoScrollGridAdapter gridAdapter=new NoScrollGridAdapter(getActivity(),imageUrls);
gridview.setAdapter(gridAdapter);
gridAdapter.notifyDataSetChanged();
