RecyclerView万能适配器

没次当我们用RecyclerView是时候，不得不想到要添加点击事件， 头部，尾部，甚至分组繁琐代码烦恼，于是本人就无奈写了共用的adapter。

使用说明：

如，item资源为 

R.layout.fragment_jiongtu_item_of_indexfregment

item里面有个imageview id为  

R.id.iv_photo

private  class JionTuAdapter extends BaseRecyclerViewAdapter
{


   public JionTuAdapter(Context context) {
      super(context);
   }


   @Override
   protected int getContentResourse() {
      return R.layout.fragment_jiongtu_item_of_indexfregment;
   }

   @Override
   protected int[] setContentViewsIds() {
      return new int[]{R.id.iv_photo};
   }

   int i = 0;

   @Override
   protected void onContentViewUpdate(BaseRecyclerViewAdapter adapter, View view, Object object) {
      //这个object就是ItemType.data
      ImageView photoView = (ImageView) adapter.getContentViewItemViewById(R.id.iv_photo);
      photoView.setImageResource((Integer) object);
   }
}

这样，我就可以轻松实现了这个适配器！

 然后，测试

recyclerView.setAdapter(adapter = new JionTuAdapter(getActivity()));

//添加内容点击事件
adapter.setOnContentViewListener(new BaseRecyclerViewAdapter.OnContentViewListener() {
   @Override
   public void onClicked(View view, BaseRecyclerViewAdapter adapter, Object object) {
      Snackbar.make(view,"呵呵",Snackbar.LENGTH_SHORT).show();
   }
});
 List<JionTuAdapter.ItemType> list = new ArrayList<JionTuAdapter.ItemType>(); for(int i =0; i < 10;i++) {   //把数据都添加到内容列表
 list.add(new BaseRecyclerViewAdapter.ItemType(BaseRecyclerViewAdapter.ItemType.TYPE_CONTENT,R.drawable.ic_launcher));
 } adapter.update(list, false);//false代表不需要提前清空列表

如果要添加头部，类似上面的adapter，分别实现

getHeaderResourse

setHeaderViewsIds

onHeaderViewUpdate
