部分适配器：继承了基础适配器

public class ItemListViewAdp
// 继承了BaseListViewAdp
		extends BaseListViewAdp<ItemsModel> {

	public ItemListViewAdp(Activity context) {
		super(context);
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		ViewHolder holder;
		if (convertView == null) {
			LayoutInflater inflater = mActivity.getLayoutInflater();
			convertView = inflater.inflate(R.layout.mainlistview_item, null);

			holder = new ViewHolder();

					.findViewById(R.id.item_myimageview);

		} else {

		// 设置item_content
		if (mArrayList.get(position).getContent() != null) {

上源码吧，差资源，都跑不起来！
