400行代码实现双人对战五子棋(适合新手入门)

跟上一篇博客一样,都是看了慕课网的视频之后写的学习记录,记录一下实现的思路,大部分内容比较简单,但也从中学到了很多东西.

按惯例首先看一下效果:(素材都是用的慕课网给的)

顺便也贴一下这个视频的连接,也推荐新手多上慕课看视频,能学到很多东西,质量也很好:Android-五子连珠

这里写图片描述

下面就一步步来实现吧

一:首先看到的是全屏的Activity,没有状态栏,在Android中要实现全屏我知道的有两种方式,推荐第二种因为第一种存在问题,下面就一一介绍一下:

1.第一种全屏方式:Manifest中设置要全屏的Activity的主题为@android:style/Theme.NoTitleBar.Fullscreen,同时需要更改Activity继承的父类为Activity,否则无法启动,如下:

<application        android:allowBackup="true"        android:icon="@mipmap/ic_launcher"        android:label="@string/app_name"        android:supportsRtl="true"        android:theme="@style/AppTheme">        <activity            android:name=".MainActivity"            android:label="@string/app_name"            android:theme="@android:style/Theme.NoTitleBar.Fullscreen">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>    </application>

Activity

public class MainActivity extends Activity { ...

缺点:正是因为这种方法更改了Activity的主题和所继承的父类,相应的会引起其他很多问题,如下:

1.修改了Activity主题,会使得在此Activity内显示的组件在4.0+设备和5.0+设备下使用同样的资源文件,如下图:

在5.1版本的设备上进行测试,本应该显示的Dialog是这样的:

这里写图片描述

结果设置了上文的主题之后却是这样的:

这里写图片描述

2.第二种问题相对于第一种就显得不是那么明显,由于这种全屏方式更换了当前Activity的父类,且默认生成的父类应该是AppCompatActivity,更换之后如果之前使用的FragmentManager对象,那么原本的获取方式是getSupportFragmentManager(),换成Activity之后就只有getFragmentManager(),目前遇到的问题只是这样.

2.第二种全屏方式:获取ActivityWindow对象,添加全屏的flag,如下:

Window window = getWindow();window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

两种方式的效果是一样的,都是示例图中的全屏状态,第二种更为方便,简单,推荐第二种.

二.主要的布局只有一个自定义的棋盘Panel组件,父组件是RelativeLayout,有一个背景图,布局文件如下:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="@drawable/bg">    <com.brioal.gobang.view.Panel        android:id="@+id/main_panel"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:layout_gravity="center"        android:layout_marginBottom="40dp" /></LinearLayout>

由于游戏结束之后设置显示的Dialog不想遮挡最后的棋盘,所以将棋盘设置了一个layout_marginBottom使棋盘整体向上移动了40dp

自定义的Panel封装了棋盘线的绘制,棋盘点击事件的处理,棋子的绘制,棋子点的存储,胜负情况的判断等,给外部的接口只是游戏的结果和重新开始游戏的方法.

三.自定义棋盘的代码书写.

1创建Panelclass文件,继承View,并添加两个构造方法,只需要处理两个参数的构造方法,单个参数的是在代码中创建View时候调用的,两个参数的是在布局文件中定义时候调用的,如下:

public class Panel extends View {public Panel(Context context) {        this(context, null);    }    public Panel(Context context, AttributeSet attrs) {        super(context, attrs);    }}

2.接下来定义一下需要用到的参数,由于要绘制棋盘的线条,棋子,等,所以需要定义的参数如下:

 private int MAX_LINE = 10; // 格子的数量    private int MAX_IN_LINE = 5; //胜利的条件    public static int WHITE_WIN = 0; //白子胜利的标志    public static int BLACK_WIN = 1; // 黑子胜利的标志    private int panleWidth; // 棋盘的宽度    private float lineHeight; // 方格的高度    private Paint mPaint; // 用于绘制线的画笔    private Paint mPaint_point; // 用于绘制点的画笔    private Bitmap mWhite; // 白色棋子    private Bitmap mBlack;//黑色棋子    private int pieceWidth; // 棋子要显示的高度    private int offset; // 棋盘离组件边界的偏移    private List<Point> mWhites; // 存储棋盘上的白子    private List<Point> mBlacks; // 存储棋盘上的黑子    private boolean isWhite = false; // 存储是否是白子 , 默认黑子先行    private boolean isGameOver = false; // 存储游戏是否已经结束    private onGameListener onGameListener; // 供外部调用的接口参数    private int mUnder; // 组件的底部的位置 , 用于确定Dialog的显示位置    public interface onGameListener { // 用于回调的接口        void onGameOVer(int i);    }

3.下一步是获取棋盘的尺寸,棋盘是正方形的,并且是以棋盘的宽度为准的,一般尺寸的获取是在onSizeChanged里面获取的,这个方法会在进行绘制之前调用,且只调用一次,并且会在屏幕尺寸发生改变的时候调用,如屏幕旋转,对尺寸参数进行处理的代码如下:

@Override    protected void onSizeChanged(int w, int h, int oldw, int oldh) {        super.onSizeChanged(w, h, oldw, oldh);        panleWidth = w; // 获取棋盘的宽度        mUnder = h - (h - panleWidth) / 2;        lineHeight = panleWidth * 1.0f / MAX_LINE; // 获取格子的高度 10行,则直线有10条 ,格子只有9个        offset = (int) (lineHeight / 2);        pieceWidth = (int) (lineHeight * 3 / 4); // 棋子的高度为格子高度的3/4        mWhite = Bitmap.createScaledBitmap(mWhite, pieceWidth, pieceWidth, false); // 根据棋子宽度进行缩放        mBlack = Bitmap.createScaledBitmap(mBlack, pieceWidth, pieceWidth, false); //根据棋子宽度进行缩放    }

4.尺寸处理完之后就需要绘制棋盘了,看示例图可以直到,棋盘线距离组件的边界都有一个偏移量,并且已经在onSizeChanged内处理过了,绘制棋盘很简单,就是一个循环就能完成全部的绘制工作.

绘制之前需要先初始化画笔,这里我们就将绘制线和绘制棋子的画笔都初始化一下,细节都在注释里面:

        mPaint = new Paint();        mPaint.setColor(0x88000000); // 设置画笔的颜色        mPaint.setAntiAlias(true); // 画笔设置抗锯齿        mPaint.setDither(true); // 画笔设置图像抖动处理,使图像更加平滑        mPaint.setStyle(Paint.Style.STROKE); // 设置绘制方式        mPaint.setStrokeWidth(2); // 设置画笔的边界宽度        mPaint_point = new Paint();        mPaint.setAntiAlias(true);        mPaint.setDither(true);        mWhite = BitmapFactory.decodeResource(getResources(), R.drawable.stone_w2); // 获取白棋的资源文件        mBlack = BitmapFactory.decodeResource(getResources(), R.drawable.stone_b1); // 获取黑棋的资源文件        mWhites = new ArrayList<>();        mBlacks = new ArrayList<>();

接下来绘制棋盘,观察棋盘可以知道,横线的起点为偏移量,终点为宽度减去偏移量,起始Y坐标与终止Y坐标相同,都为行高与当前序号的乘积,竖线绘制的参数与横线的参数完全相同,不同的只是与横线的x,y刚好相反,代码如下:

//绘制棋盘    private void drawBoard(Canvas canvas) {        int start_x = offset; // 起始 x坐标        int end_x = panleWidth - offset; // 终止x坐标        for (int i = 0; i < MAX_LINE; i++) {            float start_y = i * lineHeight + offset; // 起始的y坐标            float end_y = i * lineHeight + offset; // 终止的y坐标            canvas.drawLine(start_x, start_y, end_x, end_y, mPaint); // 绘制横向的            canvas.drawLine(start_y, start_x, end_y, end_x, mPaint); // 纵向只需要把 横向的xy交换就行        }    }

然后在onDraw内调用drawBoard即完成了棋盘的绘制,效果如下:

这里写图片描述

5.我们之前处理了白子黑子的资源文件,接下来应该处理点击事件,并且将棋子显示到棋盘上

首先我们使用List<Point>来存储棋子的位置,Point类为系统自带,在onTouch方法中对点击的位置进行计算,生成横纵坐标是棋子在棋盘中的相对位置的Point,然后添加到对应的List<Point>中去,代码如下,详细的都在注释当中:

@Override    public boolean onTouchEvent(MotionEvent event) {        if (isGameOver) {            return false;        }        int action = event.getAction();        if (action == MotionEvent.ACTION_DOWN) {            Point point = new Point((int) ((event.getX() - offset) / lineHeight), (int) ((event.getY() - offset) / lineHeight));            if (!mWhites.contains(point) && !mBlacks.contains(point)) { // 如果没有点                if (isWhite) {                    mWhites.add(point); // 存入白子                    isWhite = false;                } else {                    mBlacks.add(point); //存入黑子                    isWhite = true;                }            }            invalidate();            return true;        }        return super.onTouchEvent(event);    }

获取到了要显示的点,接下来就是遍历List,将点绘制到画布当中去,如下:

//绘制棋子    private void drawPoints(Canvas canvas) {        for (Point point : mWhites) {            canvas.drawBitmap(mWhite, offset + point.x * lineHeight - pieceWidth / 2, offset + point.y * lineHeight - pieceWidth / 2, mPaint_point);        }        for (Point point : mBlacks) {            canvas.drawBitmap(mBlack, offset + point.x * lineHeight - pieceWidth / 2, offset + point.y * lineHeight - pieceWidth / 2, mPaint_point);        }    }

6.能通过点击交替生成棋子之后需要的就是对游戏结束条件的判断,同时调用接口将结果传出,判断胜利比较麻烦,基本原理是对白子和黑子中的每一个点进行四个方向上的判断,判断是否连成5个或者是连成4个且至少存在两个空白位置,代码如下:

//判断是否游戏结束,在onDraw方法内调用    public void checkGameOver() {        boolean whiteWin = checkFiveInLine(mWhites);        boolean blackWin = checkFiveInLine(mBlacks);        if (whiteWin || blackWin) {            isGameOver = true;            if (onGameListener != null) {                onGameListener.onGameOVer(whiteWin ? WHITE_WIN : BLACK_WIN);            }        }    }    private boolean checkFiveInLine(List<Point> points) {        for (Point point : points) {            int x = point.x;            int y = point.y;            //水平方向的检查            boolean isWin1 = checkHorizontal(x, y, points);            //检查垂直方向            boolean isWin2 = checkVertical(x, y, points);            //左斜方向的检查            boolean isWin3 = checkDiagonalLeft(x, y, points);            //右斜方向的检查            boolean isWin4 = checkDiagonalRight(x, y, points);            //任意方向五子连珠 , 游戏结束            if (isWin1 || isWin2 || isWin3 || isWin4) {                return true;            }        }        return false;    }    private boolean checkDiagonalRight(int x, int y, List<Point> points) {        int count = 1;        int emptyCount = 0;        //往右上方向的判断        for (int i = 1; i < MAX_IN_LINE; i++) {            Point point = new Point(x + i, y - i);            if (points.contains(point)) {                count++;            } else {                if (!mWhites.contains(point) && !mBlacks.contains(point)) {                    emptyCount++;                }                break;            }        }        if ((count == MAX_IN_LINE - 1 && emptyCount > 0) || count == MAX_IN_LINE) {            return true;        }        //往左下方向的判断        for (int i = 1; i < MAX_IN_LINE; i++) {            Point point = new Point(x - i, y + i);            if (points.contains(point)) {                count++;            } else {                if (!mWhites.contains(point) && !mBlacks.contains(point)) {                    emptyCount++;                }                break;            }        }        if ((count == MAX_IN_LINE - 1 && emptyCount > 0) || count == MAX_IN_LINE) {            return true;        }        return false;    }    private boolean checkVertical(int x, int y, List<Point> points) {        int count = 1;        int emptyCount = 0;        //往上遍历        for (int i = 1; i < MAX_IN_LINE; i++) {            Point point = new Point(x, y - i);            if (points.contains(point)) {                count++;            } else {                if (!mBlacks.contains(point) && !mWhites.contains(point)) {                    emptyCount++;                }                break;            }        }        Log.i(TAG, "checkDiagonalLeft: " + count + ":" + emptyCount);        if ((count == MAX_IN_LINE - 1 && emptyCount > 0) || count == MAX_IN_LINE) {            return true;        }        //往下遍历        for (int i = 1; i < MAX_IN_LINE; i++) {            Point point = new Point(x, y + i);            if (points.contains(point)) {                count++;            } else {                if (!mBlacks.contains(point) && !mWhites.contains(point)) {                    emptyCount++;                }                break;            }        }        Log.i(TAG, "checkDiagonalLeft: " + count + ":" + emptyCount);        if ((count == MAX_IN_LINE - 1 && emptyCount > 0) || count == MAX_IN_LINE) {            return true;        }        return false;    }    //左斜方向的判断    private boolean checkDiagonalLeft(int x, int y, List<Point> points) {        int count = 1;        //往左上方向遍历        int emptyCount = 0;        for (int i = 1; i < MAX_IN_LINE; i++) {            Point point = new Point(x - i, y - i);            if (points.contains(point)) {                count++;            } else {                if (!mBlacks.contains(point) && !mWhites.contains(point)) {                    emptyCount++;                }                break;            }        }        if ((count == MAX_IN_LINE - 1 && emptyCount > 0) || count == MAX_IN_LINE) {            return true;        }        //往右下方向的判断        for (int i = 1; i < MAX_IN_LINE; i++) {            Point point = new Point(x + i, y + i);            if (points.contains(point)) {                count++;            } else {                if (!mBlacks.contains(point) && !mWhites.contains(point)) {                    emptyCount++;                }                break;            }        }        if ((count == MAX_IN_LINE - 1 && emptyCount > 0) || count == MAX_IN_LINE) {            return true;        }        return false;    }    //检查水平方向    private boolean checkHorizontal(int x, int y, List<Point> points) {        int count = 1;        int emptyCount = 0;        //往左遍历        for (int i = 1; i < MAX_IN_LINE; i++) {            Point point = new Point(x - i, y);            if (points.contains(point)) { // 是否包含点                count++;            } else {                if (!mBlacks.contains(point) && !mWhites.contains(point)) {                    emptyCount++;                }                break;            }        }        if ((count == MAX_IN_LINE - 1 && emptyCount > 0) || count == MAX_IN_LINE) {            return true;        }        //往右遍历        for (int i = 1; i < MAX_IN_LINE; i++) {            Point point = new Point(x + i, y);            if (points.contains(point)) {                count++;            } else {                if (!mBlacks.contains(point) && !mWhites.contains(point)) {                    emptyCount++;                }                break;            }        }        if ((count == MAX_IN_LINE - 1 && emptyCount > 0) || count == MAX_IN_LINE) {            return true;        }        return false;    }

7.对重新开始一局游戏的处理,如下:

 //重新开始游戏    public void reStartGame() {        mWhites.clear(); // 清理白子        mBlacks.clear(); // 清理黑子        isGameOver = false; // 游戏未结束        isWhite = false; // 黑子先手        invalidate(); // 重绘    }

8.暴露回调接口:

public void setOnGameListener(Panel.onGameListener onGameListener) {        this.onGameListener = onGameListener;    }

9,返回棋盘的底部坐标:

  public int getUnder() {        return mUnder;    }

自定义棋盘View就完成了,接下来是Activity中的处理,如下:

设置Dialog的位置:

Window dialogWindow = dialog.getWindow();                WindowManager.LayoutParams params = new WindowManager.LayoutParams();                params.x = 0;//设置x坐标                params.y =panel.getUnder();//设置y坐标                dialogWindow.setAttributes(params);

余下的内容没有什么需要细说的,就直接上代码:

private Panel panel; // 棋盘VIew    private AlertDialog.Builder builder; //Dialog构建    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        Window window = getWindow();        window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); // 设置全屏        builder = new AlertDialog.Builder(MainActivity.this);        builder.setTitle("游戏结束"); // 设置Dialog的标题        builder.setNegativeButton("退出", new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) { // 设置退出按钮和点击事件                MainActivity.this.finish();            }        });        builder.setPositiveButton("再来一局", new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) { // 设置再来一局的按钮和点击事件                panel.reStartGame();            }        });        panel = (Panel) findViewById(R.id.main_panel);        panel.setOnGameListener(new Panel.onGameListener() {            @Override            public void onGameOVer(int i) { // 设置监听器                String text = "";                if (i == Panel.WHITE_WIN) {                    //白子胜利                    text = "白子胜利";                } else if (i == Panel.BLACK_WIN) {                    //黑子胜利                    text = "黑子胜利";                }                builder.setMessage(text); // 设置Dialog内容                builder.setCancelable(false); // 设置不可返回键取消                AlertDialog dialog = builder.create(); // 构建Dialog                Window dialogWindow = dialog.getWindow();                 WindowManager.LayoutParams params = new WindowManager.LayoutParams();                params.x = 0;//设置x坐标                params.y = panel.getUnder();//设置y坐标                dialogWindow.setAttributes(params); // 设置新的LayoutParams                dialog.setCanceledOnTouchOutside(false); // 设置点击外部不取消                dialog.show(); // 显示Dialog            }        });    }

至此所有代码就完成了,下面贴一下MainActivityPanel的全部代码,注释较全面.
