}

if (convertView == null) {
return new BaseViewHolder(context, parent, layoutId, position);
}else {
BaseViewHolder holder = (BaseViewHolder) convertView.getTag();
return holder;
}
}
/**
* 通过viewId获取控件
* @param viewId
* @return
*/
public <T extends View>T getView(int viewId){
View view = mViews.get(viewId);

if (view == null) {
view = mConvertView.findViewById(viewId);
mViews.put(viewId, view);
}
return (T)view;
}

public View getConvertView(){
return mConvertView;
}

*
* @param position    The position of the item within the adapter's data set of the item whose view
*                    we want.
* @param convertView The old view to reuse, if possible. Note: You should check that this view
*                    is non-null and of an appropriate type before using. If it is not possible to convert
*                    this view to display the correct data, this method can create a new view.
*                    Heterogeneous lists can specify their number of view types, so that this View is
*                    always of the right type (see {@link #getViewTypeCount()} and
*                    {@link #getItemViewType(int)}).
* @param parent      The parent that this view will eventually be attached to
* @return A View corresponding to the data at the specified position.
