封装一个基础BaseAdapter类

public abstract class MyBaseAdapter<T> extends BaseAdapter {    private List<T> data;    private LayoutInflater inflater;    private int layoutRes;    public MyBaseAdapter(Context context, int layoutRes, List<T> data) {        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);        this.layoutRes = layoutRes;        if (data == null) {            this.data = new ArrayList<>();        } else {            this.data = data;        }    }    public void updateRes(List<T> data) {//        this.data.clear();//        this.data.addAll(data);        this.data = data;        notifyDataSetChanged();    }    public void removeRes(int position) {        data.remove(position);        notifyDataSetChanged();    }    public void adddateRes(List<T> data) {        if (data != null && data.size() > 0) {            this.data.addAll(data);            notifyDataSetChanged();        }    }    public int getCount() {        return data != null ? data.size() : 0;    }    public T getItem(int position) {        return data.get(position);    }    public long getItemId(int position) {        return position;    }    public View getView(int position, View convertView, ViewGroup parent) {        ViewHolder holder = null;        if (convertView == null) {            convertView = inflater.inflate(layoutRes, parent, false);            holder = new ViewHolder(convertView);            convertView.setTag(holder);        } else {            holder = (ViewHolder) convertView.getTag();        }        bindData(position, holder, getItem(position));        return convertView;    }    public abstract void bindData(int position, ViewHolder holder, T t);    protected static class ViewHolder {        public View layout;        private Map<Integer, View> cacheView;        public ViewHolder(View convertView) {            layout = convertView;            cacheView = new HashMap<>();        }        public View getView(int resId) {            View view = null;            if (cacheView.containsKey(resId)) {                view = cacheView.get(resId);            } else {                view = layout.findViewById(resId);                cacheView.put(resId, view);            }            return view;        }    }}
