RecyclerView单选

记录下今天RecyclerView单选实现

class HomeAdapter extends RecyclerView.Adapter implements View.OnClickListener {

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        MyViewHolder holder = new MyViewHolder(LayoutInflater.from(CashInstallActivity.this).inflate(R.layout.rcycleritem, parent, false));
        return holder;
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, final int position) {
        holder.tv_qs.setText(mDatas.get(position).getFq_Qs());
        holder.tv_fqje.setText(mDatas.get(position).getFq_Je());

        if (position == clickPosition) {
            holder.rb_check.setChecked(true);
            //holder.iv_test.setVisibility(View.VISIBLE);
        } else {
            holder.rb_check.setChecked(false);
           // holder.iv_test.setVisibility(View.GONE);
        }

        //holder.relativeLayout.setTag(position);
        //holder.relativeLayout.setOnClickListener(this);

        holder.rb_check.setTag(position);
        holder.rb_check.setOnClickListener(this);
    }

    @Override
    public int getItemCount() {
        if (mDatas.size() > 0) {
            return mDatas.size();
        } else {
            return 0;
        }
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.rl_click:
                Message msg = Message.obtain();
                clickPosition = (Integer) v.getTag();
                msg.arg1 = clickPosition;
                msg.what = RECYCLER_VIEW;
                handler.sendMessage(msg);
                notifyDataSetChanged();
        }
    }

    class MyViewHolder extends RecyclerView.ViewHolder {

        TextView tv_qs;
        TextView tv_fqje;
        RadioButton rb_check;

        //ImageView iv_test;
        //RelativeLayout relativeLayout;

        public MyViewHolder(View itemView) {
            super(itemView);
            tv_qs = (TextView) itemView.findViewById(R.id.tv_qs);
            tv_fqje = (TextView) itemView.findViewById(R.id.tv_fqje);
            rb_check = (RadioButton) itemView.findViewById(R.id.read_tag01);

            //iv_test = (ImageView) itemView.findViewById(R.id.iv_test);

            //relativeLayout = (RelativeLayout) itemView.findViewById(R.id.rl_click);
        }
    }
}

这是关键的实现代码。
