超级好用的仿recycleview的listview适配器与viewholder封装

标签：viewholder return int 适配器 recycleview viewHolder context data public

由于公司项目频繁使用适配器,于是就使用java牛逼的泛型写了这和Recycleviwew那样的设计架构的lsitview adapter

超级好用的仿recycleview的listview适配器与viewholder+ javabean 解耦

已经实现好了复用了,另外如果要给适配器设置tag,你也可以改我这代码的,比如改我这个价一个资源id绑定什么的，

超级简单实用，比谁的都简单。绝对原创，你不要嘲笑我说这个东西过时了，我一直在用pulltoRefushListview做下拉上拉,而recyclview还是有一点的局限性的.暂时没发现牛逼人物做到了用recycleview实现了上拉下拉左拉右拉，公司的项目横向刷新我采用的也是recycleview,但是我都没有做那个拉的回弹什么的，只是当到了最后一条就自动加载更多....好了废话不多说了，希望大家喜欢我的文章，为我点赞，特别是github的项目哈...

如何使用?

附上一个使用的例子，这个例子就是我做公司交给我的闹钟提醒需求viewholder,和adapater：

viewholder

    public final TextView tvTime;
    public final TextView tvMode;
    public final TextView tvContent;

    public final View viewType;

    public RemindViewHolder(View view) {
        super(view);
        viewType =  view.findViewById(R.id.view_type);
        tvMode = (TextView) view.findViewById(R.id.tv_content1);
        tvTime = (TextView) view.findViewById(R.id.tv_content2);

        checkBox = (CheckBox) view.findViewById(R.id.switchButton);

    }
    public interface OnAddClickListener {

    }

    public OnAddClickListener getOnAddClickListener() {
        return onAddClickListener;

上面的适配器是listview需求中比较常见的多种item的实现。没有基础的可以看下面这个简单一点的- -

/**
 * Created by luozheng on 2016-01-06 14:42:12.
 */
public class StoryListAdapter extends SuperAdapter<BaseStoryModel,StoryListViewHolder> {

    private HomeModel playListHomeModel;

    public StoryListAdapter(List<BaseStoryModel>baseStoryModels, Context context) {
        super(baseStoryModels,context);
        playListHomeModel = GlobalInfo.getPlayListHomeModel();
        if(playListHomeModel==null){
            playListHomeModel=new HomeModel();
        }
    }

    @Override
    public StoryListViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
       return new StoryListViewHolder(LayoutInflater.from(context).inflate(R.layout.view_item_play_list,parent,false));
    }
    @Override
    public void onBindViewHolder(StoryListViewHolder viewHolder, int position, int viewType) {
        final BaseStoryModel storyModel = getData().get(position);
      
}

总之我写的都是 javaben viewhoder,adapter的结合了..不需要bean的可以再进行修改咯，不过几乎没有不用bean的吧？上面的baseStoryModel就是一个bean了。

new adapter的时候传递的是list集合里面放的是上面申明的javabean。。。
