androidstudio五子棋游戏

以下是基于Android Studio开发的五子棋游戏的实现方法： 1. 首先，我们需要定义一个ChessView类，并在其中定义一些成员变量，以便于后续使用。在需要显示五子棋的布局文件中引入该自定义View。 2. 接下来，我们需要编写构造函数，并在其中进行一些初始化设置。例如，初始化画笔以及将棋子图片转换为bitmap等。 3. 在onMeasure()方法中获取屏幕宽高，在onSizeChanged()方法中获取棋盘的宽度，并计算出棋盘的行高。然后，根据行高缩放棋子大小，使其显示大小合适。 4. 每次调用invalidate()方法时，都会调用onDraw()方法进行界面绘制。在该方法中，我们需要先绘制棋盘，然后绘制用户所下的棋子。 5. 对于人机对战模式，我们需要实现一些简单的算法，以实现人机交互。对于人人对战模式，我们只需要进行输赢方的判定即可。 下面是一个简单的五子棋游戏的实现代码： ```java public class ChessView extends View { private int mPanelWidth; private float mLineHeight; private Bitmap mWhitePiece; private Bitmap mBlackPiece; private float ratioPieceOfLineHeight = 3 * 1.0f / 4; private boolean mIsWhite = true; private ArrayList<Point> mWhiteArray = new ArrayList<>(); private ArrayList<Point> mBlackArray = new ArrayList<>(); private boolean mIsGameOver; private boolean mIsWhiteWinner; private int MAX_LINE = 10; private Paint mPaint = new Paint(); public ChessView(Context context, AttributeSet attrs) { super(context, attrs); setBackgroundColor(0x44ff0000); init(); } private void init() { mPaint.setColor(0x88000000); mPaint.setAntiAlias(true); mPaint.setDither(true); mPaint.setStyle(Paint.Style.STROKE); mWhitePiece = BitmapFactory.decodeResource(getResources(), R.drawable.stone_w2); mBlackPiece = BitmapFactory.decodeResource(getResources(), R.drawable.stone_b1); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int widthSize = MeasureSpec.getSize(widthMeasureSpec); int heightSize = MeasureSpec.getSize(heightMeasureSpec); int widthMode = MeasureSpec.getMode(widthMeasureSpec); int heightMode = MeasureSpec.getMode(heightMeasureSpec); int width = Math.min(widthSize, heightSize); if (widthMode == MeasureSpec.UNSPECIFIED) { width = heightSize; } else if (heightMode == MeasureSpec.UNSPECIFIED) { width = widthSize; } setMeasuredDimension(width, width); } @Override protected void onSizeChanged(int w, int h, int oldw, int oldh) { super.onSizeChanged(w, h, oldw, oldh); mPanelWidth = w; mLineHeight = mPanelWidth * 1.0f / MAX_LINE; int pieceWidth = (int) (mLineHeight * ratioPieceOfLineHeight); mWhitePiece = Bitmap.createScaledBitmap(mWhitePiece, pieceWidth, pieceWidth, false); mBlackPiece = Bitmap.createScaledBitmap(mBlackPiece, pieceWidth, pieceWidth, false); } @Override public boolean onTouchEvent(MotionEvent event) { if (mIsGameOver) { return false; } int action = event.getAction(); if (action == MotionEvent.ACTION_UP) { int x = (int) event.getX(); int y = (int) event.getY(); Point p = getValidPoint(x, y); if (mWhiteArray.contains(p) || mBlackArray.contains(p)) { return false; } if (mIsWhite) { mWhiteArray.add(p); } else { mBlackArray.add(p); } invalidate(); mIsWhite = !mIsWhite; } return true; } private Point getValidPoint(int x, int y) { return new Point((int) (x / mLineHeight), (int) (y / mLineHeight)); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); drawBoard(canvas); drawPieces(canvas); checkGameOver(); } private void drawBoard(Canvas canvas) { int w = mPanelWidth; float lineHeight = mLineHeight; for (int i = 0; i < MAX_LINE; i++) { int startX = (int) (lineHeight / 2); int endX = (int) (w - lineHeight / 2); int y = (int) ((0.5 + i) * lineHeight); canvas.drawLine(startX, y, endX, y, mPaint); canvas.drawLine(y, startX, y, endX, mPaint); } } private void drawPieces(Canvas canvas) { for (int i = 0, n = mWhiteArray.size(); i < n; i++) { Point whitePoint = mWhiteArray.get(i); canvas.drawBitmap(mWhitePiece, (whitePoint.x + (1 - ratioPieceOfLineHeight) / 2) * mLineHeight, (whitePoint.y + (1 - ratioPieceOfLineHeight) / 2) * mLineHeight, null); } for (int i = 0, n = mBlackArray.size(); i < n; i++) { Point blackPoint = mBlackArray.get(i); canvas.drawBitmap(mBlackPiece, (blackPoint.x + (1 - ratioPieceOfLineHeight) / 2) * mLineHeight, (blackPoint.y + (1 - ratioPieceOfLineHeight) / 2) * mLineHeight, null); } } private void checkGameOver() { boolean whiteWin = checkFiveInLine(mWhiteArray); boolean blackWin = checkFiveInLine(mBlackArray); if (whiteWin || blackWin) { mIsGameOver = true; mIsWhiteWinner = whiteWin; String text = mIsWhiteWinner ? "白棋胜利" : "黑棋胜利"; Toast.makeText(getContext(), text, Toast.LENGTH_SHORT).show(); } } private boolean checkFiveInLine(List<Point> points) { for (Point p : points) { int x = p.x; int y = p.y; boolean win = checkHorizontal(x, y, points); if (win) return true; win = checkVertical(x, y, points); if (win) return true; win = checkLeftDiagonal(x, y, points); if (win) return true; win = checkRightDiagonal(x, y, points); if (win) return true; } return false; } private boolean checkHorizontal(int x, int y, List<Point> points) { int count = 1; for (int i = 1; i < 5; i++) { if (points.contains(new Point(x - i, y))) { count++; } else { break; } } if (count == 5) return true; for (int i = 1; i < 5; i++) { if (points.contains(new Point(x + i, y))) { count++; } else { break; } } if (count == 5) return true; return false; } private boolean checkVertical(int x, int y, List<Point> points) { int count = 1; for (int i = 1; i < 5; i++) { if (points.contains(new Point(x, y - i))) { count++; } else { break; } } if (count == 5) return true; for (int i = 1; i < 5; i++) { if (points.contains(new Point(x, y + i))) { count++; } else { break; } } if (count == 5) return true; return false; } private boolean checkLeftDiagonal(int x, int y, List<Point> points) { int count = 1; for (int i = 1; i < 5; i++) { if (points.contains(new Point(x - i, y + i))) { count++; } else { break; } } if (count == 5) return true; for (int i = 1; i < 5; i++) { if (points.contains(new Point(x + i, y - i))) { count++; } else { break; } } if (count == 5) return true; return false; } private boolean checkRightDiagonal(int x, int y, List<Point> points) { int count = 1; for (int i = 1; i < 5; i++) { if (points.contains(new Point(x + i, y + i))) { count++; } else { break; } } if (count == 5) return true; for (int i = 1; i < 5; i++) { if (points.contains(new Point(x - i, y - i))) { count++; } else { break; } } if (count == 5) return true; return false; } } ```

### Android Studio五子棋游戏开发示例与教程 在Android Studio中开发五子棋游戏，需要结合用户界面设计、事件处理以及AI逻辑实现。以下是一个完整的五子棋游戏开发思路和代码示例。 #### 1. 用户界面设计 使用`GridLayout`作为棋盘布局，每个格子可以是一个`ImageView`或`Button`，用于显示玩家的落子状态。棋盘大小可以根据需求设置为15×15或其他尺寸。 ```xml <GridLayout android:id="@+id/chessboard" android:layout_width="match_parent" android:layout_height="match_parent" android:columnCount="15" android:rowCount="15"> </GridLayout> ``` #### 2. 玩家落子逻辑 玩家点击棋盘上的某个位置时，触发`onUserMove`方法。以下是基于Java的实现： ```java public void onUserMove(int x, int y) { boolean success = placePiece(x, y, 1); // 玩家尝试落子 if (success) { // 更新游戏状态 updateGameState(); } else { // 如果落子失败，提示玩家重新落子 System.out.println("Invalid move. Try again."); } } private boolean placePiece(int x, int y, int player) { if (board[x][y] == 0) { // 检查该位置是否为空 board[x][y] = player; // 落子 return true; } return false; } ``` #### 3. 游戏状态更新 每次玩家落子后，都需要检查游戏状态是否发生变化（如是否有玩家获胜）。以下是`updateGameState`方法的实现： ```java private void updateGameState() { if (checkGameOver()) { // 检查游戏是否结束 System.out.println("Game over!"); } else { // 如果游戏未结束，调用电脑AI落子逻辑 makeAIMove(); } } private boolean checkGameOver() { for (int i = 0; i < 15; i++) { for (int j = 0; j < 15; j++) { if (checkWin(i, j, 1) || checkWin(i, j, -1)) { return true; // 如果有玩家获胜，返回true } } } return false; } private boolean checkWin(int x, int y, int player) { // 检查水平、垂直和对角线方向是否有五个连续的棋子 int[][] directions = {{0, 1}, {1, 0}, {1, 1}, {1, -1}}; for (int[] dir : directions) { int count = 1; for (int k = 1; k < 5; k++) { int newX = x + k * dir[0]; int newY = y + k * dir[1]; if (newX >= 0 && newX < 15 && newY >= 0 && newY < 15 && board[newX][newY] == player) { count++; } else { break; } } if (count >= 5) { return true; } } return false; } ``` #### 4. 电脑AI落子逻辑 电脑AI可以通过简单的策略实现，例如随机选择一个空位，或者优先选择靠近玩家最近落子的位置。 ```java private void makeAIMove() { Random random = new Random(); while (true) { int x = random.nextInt(15); int y = random.nextInt(15); if (placePiece(x, y, -1)) { // 电脑落子 updateGameState(); break; } } } ``` #### 5. 棋谱功能 为了方便调试，可以将每一步的落子记录到数组中，如下所示： ```java List<String> manu = new ArrayList<>(); public void addMoveToManu(int x, int y) { String move = String.format("%c%d", 'A' + x, y + 1); // 将坐标转换为棋谱格式 manu.add(move); } public void printManu() { for (String move : manu) { System.out.print(move + " "); } System.out.println(); } ``` #### 示例运行流程 1. 初始化棋盘并监听用户点击事件。 2. 玩家点击棋盘，触发`onUserMove`方法。 3. 检查游戏状态是否发生变化。 4. 如果游戏未结束，调用电脑AI落子逻辑。 5. 输出当前棋谱以便调试[^2]。 ###
