view group adapter的封装

注意：添加视图要在视图完成后添加，没完成添加的就是没完成的
写adapter不一样的主要的就是数据，视图
创建个接口，接收数据绑定视图

public interface ViewPageHolder<T> {    View createView(ViewGroup viewGroup);    void bind(T data);}

adapter中用这接口创建视图和绑定视图就行了

public class ViewPageAdapterW<T> extends PagerAdapter@Override    public Object instantiateItem(ViewGroup container, int position) {        View view = viewPageHolder.createView(container);        viewPageHolder.bind(mData.get(position));        container.addView(view);        return view;    }

用就方便了

class MyHolder implements ViewPageHolder<EntityImage> {        private ImageView mImageView;        @Override        public View createView(ViewGroup viewGroup) {            View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.view_page_item, viewGroup, false);            mImageView = (ImageView) v.findViewById(R.id.image_view);            return v;        }        @Override        public void bind(EntityImage data) {            mImageView.setImageResource(data.imageRes);        }    }
