先前創建房間時有呼叫一個外部的class，叫CreateBoardData，我們可將一些棋盤棋子的初始設置儲存在這裡

CreateBoardData

先加入一些變數用來儲存值

    private String player;
    private Activity activity;
    private PlayerChessboardData playerChessboardData;
    private HashMap<String,Object> chessboardData = new HashMap<>();
    private HashMap<String,Object> chessmanMoveData = new HashMap<>();
    private HashMap<String,Object> pawnMove1 = new HashMap<>();
    private HashMap<String,Object> pawnMove2 = new HashMap<>();
    private HashMap<String,Object> castlingMove1 = new HashMap<>();
    private HashMap<String,Object> castlingMove2 = new HashMap<>();
    private ArrayList<TextView> chessboard = new ArrayList<>();
    private ArrayList<Button> chessman = new ArrayList<>();
    private ArrayList<TextView> chessmanSelect = new ArrayList<>();
    private String[] board_coordinate;
    private ColorData colorData = new ColorData();

接著我們加入建構元，讓呼叫class時可以直接傳入參數，以及作相對應的初始化

public CreateBoardData(Activity activity, String player){
        this.activity = activity;
        this.player = player;
        if(player.equals("1")){
            playerChessboardData = new PlayerChessboardData("1");
            board_coordinate = new String[]{
                    "","a","b","c","d","e","f","g","h","",
                    "8","7","6","5","4","3","2","1",
                    "8","7","6","5","4","3","2","1",
                    "","a","b","c","d","e","f","g","h",""
            };
        } else if (player.equals("2")) {
            playerChessboardData = new PlayerChessboardData("2");
            board_coordinate = new String[]{
                    "","h","g","f","e","d","c","b","a","",
                    "1","2","3","4","5","6","7","8",
                    "1","2","3","4","5","6","7","8",
                    "","h","g","f","e","d","c","b","a",""
            };
        }else{
            board_coordinate = new String[]{};
        }
    }

• 初始化棋盤資料

// 棋盤資料
    public HashMap<String,Object> CreateChessboard(){
        chessboardData.put("a8","bR");
        chessboardData.put("b8","bN");
        chessboardData.put("c8","bB");
        chessboardData.put("d8","bQ");
        chessboardData.put("e8","bK");
        chessboardData.put("f8","bB");
        chessboardData.put("g8","bN");
        chessboardData.put("h8","bR");

        chessboardData.put("a7","bP");
        chessboardData.put("b7","bP");
        chessboardData.put("c7","bP");
        chessboardData.put("d7","bP");
        chessboardData.put("e7","bP");
        chessboardData.put("f7","bP");
        chessboardData.put("g7","bP");
        chessboardData.put("h7","bP");

        chessboardData.put("a6","  ");
        chessboardData.put("b6","  ");
        chessboardData.put("c6","  ");
        chessboardData.put("d6","  ");
        chessboardData.put("e6","  ");
        chessboardData.put("f6","  ");
        chessboardData.put("g6","  ");
        chessboardData.put("h6","  ");

        chessboardData.put("a5","  ");
        chessboardData.put("b5","  ");
        chessboardData.put("c5","  ");
        chessboardData.put("d5","  ");
        chessboardData.put("e5","  ");
        chessboardData.put("f5","  ");
        chessboardData.put("g5","  ");
        chessboardData.put("h5","  ");

        chessboardData.put("a4","  ");
        chessboardData.put("b4","  ");
        chessboardData.put("c4","  ");
        chessboardData.put("d4","  ");
        chessboardData.put("e4","  ");
        chessboardData.put("f4","  ");
        chessboardData.put("g4","  ");
        chessboardData.put("h4","  ");

        chessboardData.put("a3","  ");
        chessboardData.put("b3","  ");
        chessboardData.put("c3","  ");
        chessboardData.put("d3","  ");
        chessboardData.put("e3","  ");
        chessboardData.put("f3","  ");
        chessboardData.put("g3","  ");
        chessboardData.put("h3","  ");

        chessboardData.put("a2","wP");
        chessboardData.put("b2","wP");
        chessboardData.put("c2","wP");
        chessboardData.put("d2","wP");
        chessboardData.put("e2","wP");
        chessboardData.put("f2","wP");
        chessboardData.put("g2","wP");
        chessboardData.put("h2","wP");

        chessboardData.put("a1","wR");
        chessboardData.put("b1","wN");
        chessboardData.put("c1","wB");
        chessboardData.put("d1","wQ");
        chessboardData.put("e1","wK");
        chessboardData.put("f1","wB");
        chessboardData.put("g1","wN");
        chessboardData.put("h1","wR");

        return chessboardData;
    }

• 初始化棋譜資料

// 棋譜資料
    public HashMap<String,Object> CreateChessmanMove(){
        chessmanMoveData.put("0","");

        return chessmanMoveData;
    }

• 初始化玩家1、2士兵升變狀態資料

// 玩家1士兵升變資料
    public HashMap<String,Object> CreatePawnMove1(){
        pawnMove1.put("a4",false);
        pawnMove1.put("b4",false);
        pawnMove1.put("c4",false);
        pawnMove1.put("d4",false);
        pawnMove1.put("e4",false);
        pawnMove1.put("f4",false);
        pawnMove1.put("g4",false);
        pawnMove1.put("h4",false);

        return pawnMove1;
    }
    // 玩家2士兵升變資料
    public HashMap<String,Object> CreatePawnMove2(){
        pawnMove2.put("h5",false);
        pawnMove2.put("g5",false);
        pawnMove2.put("f5",false);
        pawnMove2.put("e5",false);
        pawnMove2.put("d5",false);
        pawnMove2.put("c5",false);
        pawnMove2.put("b5",false);
        pawnMove2.put("a5",false);

        return pawnMove2;
    }

• 初始化玩家1、2王車易位資料

// 玩家1王車易位資料
    public HashMap<String,Object> CreateCastlingMove1(){
        castlingMove1.put("a1",true);
        castlingMove1.put("e1",true);
        castlingMove1.put("h1",true);

        return castlingMove1;
    }
    // 玩家2王車易位資料
    public HashMap<String,Object> CreateCastlingMove2(){
        castlingMove2.put("h8",true);
        castlingMove2.put("e8",true);
        castlingMove2.put("a8",true);

        return castlingMove2;
    }

這樣我們在先前創建房間時，就可以直接呼叫到這裡的function了
