Recyclerview自定义点击事件（以及Fresco中SimpleDraweeView的使用）

依赖：

 

   compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'

 
在Activity中设置Recyclerview的布局管理器：

    

     mRlv.setLayoutManager(new LinearLayoutManager(this));        leftAdapter = new LeftAdapter(data, this);        mRlv.setAdapter(leftAdapter);        leftAdapter.setOnItemClickLisenter(new LeftAdapter.OnItemClickLisenter() {            @Override            public void onitemClick(int a) {                 leftPersent.getRight("getProductCatagory",a);

Recyclerview的适配器

 

public class RightRLVAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder>{    private  List<RightBean.DataBean.ListBean> list;    private Context context;    private String s;    public RightRLVAdapter( List<RightBean.DataBean.ListBean> list, Context context) {        this.list = list;        this.context = context;    }    //创建新View，被LayoutManager所调用      @Override    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.rightrvlitem,viewGroup,false);        ViewHolder vh = new ViewHolder(view);        return vh;    }    @Override    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {        RightBean.DataBean.ListBean listBean = list.get(position);        ViewHolder vh= (ViewHolder) holder;        String icon = listBean.getIcon();        Uri uri=Uri.parse(icon);        vh.mTextView.setText(listBean.getName());        vh.sdv.setImageURI(uri);    }    //获取数据的数量      @Override    public int getItemCount() {        return list.size();    }    //自定义的ViewHolder，持有每个Item的的所有界面元素      public static class ViewHolder extends RecyclerView.ViewHolder {        public TextView mTextView;       SimpleDraweeView sdv;        public ViewHolder(View view){            super(view);            mTextView = (TextView) view.findViewById(R.id.tv2);            sdv=view.findViewById(R.id.sdl);        }    }    public interface OnItemClickLisenter{        void onitemClick(int a);    }    private OnItemClickLisenter onItemClickLisenter;    public void setOnItemClickLisenter(OnItemClickLisenter onItemClickLisenter){        this.onItemClickLisenter=onItemClickLisenter;    }}

rightrvlitem的布局：
