RecyView使用按钮加减删除、点击Item删除

适配器代码：

  

class MyRecyclerViewBase extends RecyclerView.Adapter<MyRecyclerViewBase.ViewHodler> implements View.OnClickListener {

    private Context context;
    private List<String> list;

    public MyRecyclerViewBase(Context context, List<String> list) {
        this.context = context;
        this.list = list;
    }

    @Override
    public ViewHodler onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = View.inflate(context, R.layout.mybase, null);
        v.setOnClickListener(this);
        ViewHodler hodler = new ViewHodler(v);
        return hodler;
    }

    @Override
    public void onBindViewHolder(ViewHodler holder, final int position) {
        holder.tv.setText(list.get(position));
        holder.image.setImageResource(R.drawable.ic_launcher_background);
        holder.itemView.setTag(position);
    }

    @Override
    public void onClick(View v) {
        if (mItemClickListener != null) {
            mItemClickListener.onItemClick((Integer) v.getTag());
        }
    }


    class ViewHodler extends RecyclerView.ViewHolder {

        private final ImageView image;
        private final TextView tv;

        public ViewHodler(View v) {
            super(v);
            image = (ImageView) v.findViewById(R.id.imageView);
            tv = (TextView) v.findViewById(R.id.textView);

        }
    }

    @Override
    public int getItemCount() {
        return list.size();
    }

    //增加
    public void addData(int position, String data) {
        list.add(position, data);
        notifyItemInserted(position);
    }

    //删除
    public void removeData(int position) {
        list.remove(position);
        notifyItemRemoved(position);
    }

    //定义接口
    public interface OnItemClickListener {
        void onItemClick(int position);
    }

    //声明接口对象
    private OnItemClickListener mItemClickListener;

    //判断
    public void setItemClickListener(OnItemClickListener itemClickListener) {
        mItemClickListener = itemClickListener;
    }

}
