Android Recyclerview嵌套 列表裡面套列表

最近，項目中遇到一個問題，就是列表顯示的嵌套，外面是一個RecyclerView列表，而其中一個單項竟然也是列表，產品設計的是否規范暫且不論，先想辦法實現吧，本以為這樣嵌套很難實現，結果寫下來也不過如此，雖然寫的時候內心很刺激。

方法：按照正常實現就可，那個單項布局裡放一個RecyclerView,在holder裡find到它，然後在給它接上一個適配器，也就是在外層列表Adapter中，再給它的單項子控件配一個Adapter,就問你刺激不？？？廢話少說，上代碼，客官請看…….

public class ContractDeatilAdapter extends
        RecyclerView.Adapter {

    private static final int TYPE_SIMPLE = 1;//普通簡易布局，只有兩個textview
    private static final int TYPE_INSTALMENT = 2;//分期付款的布局

    private Context mContext;
    private List valueList;
    private List keyList;
    private List payStagesList;

    public ContractDeatilAdapter(Context mContext, List valueList, List keyList,
                                 List payStagesList) {
        this.mContext = mContext;
        this.valueList = valueList;
        this.keyList = keyList;
        this.payStagesList = payStagesList;
    }

    @Override
    public ContractDetailHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(mContext).inflate(R.layout.item_contract_detail_instalment, parent, false);
        return new ContractInstalmentHolder(itemView);
    }


    @Override
    public int getItemCount() {
        if (valueList != null && payStagesList != null) {
            return valueList.size() + payStagesList.size();
        }
        return 0;
    }

    @Override
    public void onBindViewHolder(ContractDetailHolder holder, int position) {
            ContractInstalmentHolder instalmentHolder = (ContractInstalmentHolder) holder;

            int stagePosition = position - valueList.size();
            StagePayDetailAdapter mRefundAdapter = new StagePayDetailAdapter(mContext,
                    payStagesList.get(stagePosition).getRentpactpaylists());
            ((ContractInstalmentHolder) holder).rvRefundDetail.setLayoutManager(new LinearLayoutManager(mContext){
                @Override
                public boolean canScrollVertically() {
                    return false;
                }
            });
            ((ContractInstalmentHolder) holder).rvRefundDetail.setAdapter(mRefundAdapter);
        }
    }

    class ContractDetailHolder extends RecyclerView.ViewHolder {
        public ContractDetailHolder(View itemView) {
            super(itemView);
        }
    }



    /**
     * 分期付款詳情 的holder
     */
    class ContractInstalmentHolder extends ContractDetailHolder {
        TextView tvGrade;
        LinearLayout layoutTitle;
        TextView tvPay, tvBeginDate, tvPayDate, tvOverDate;
        RecyclerView rvRefundDetail;
        TextView tvMemo;

        public ContractInstalmentHolder(View itemView) {
            super(itemView);
            layoutTitle = (LinearLayout) itemView.findViewById(R.id.layout_title);
            tvGrade = (TextView) itemView.findViewById(R.id.tv_grade);
            tvPay = (TextView) itemView.findViewById(R.id.tv_pay);

            tvMemo = (TextView) itemView.findViewById(R.id.tv_memo);
        }

    }
