Android游戏之数独游戏开发

 数独游戏是一种源自18世纪末的瑞士的游戏，后在美国发展、并在日本得以发扬光大的数学智力拼图游戏。在每一个小九宫格中，分别填上1至9的数字，让整个大九宫格每一列、每一行的数字都不重复。 数独的玩法逻辑简单，数字排列方式千变万化，是锻炼脑筋的好方法。

本文实现简单的数独游戏，通过mars的视频教程完成编程
1.自定义View：

package com.example.administrator.shudugame;

/**
 * Created by Administrator on 2016/9/19.
 */

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Paint.Align;
import android.graphics.Paint.FontMetrics;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;

public class MyView extends View{

  public MyView(Context context, AttributeSet attrs) {
    super(context, attrs);
  }
  //方格长宽
  float width;
  float height;
  //选定的坐标
  int selectX;
  int selectY;
  MyGame mGame=new MyGame();

  //获得屏幕尺寸
  @Override
  protected void onSizeChanged(int w, int h, int oldw, int oldh) {
    super.onSizeChanged(w, h, oldw, oldh);
    //每一个小格的长宽
    this.width=w/9f;
    this.height=h/9f*2/3;
  }


  //绘图函数
  @Override
  protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    //画背景
    Paint bgPaint=new Paint();
    bgPaint.setColor(getResources().getColor(R.color.bg));
    canvas.drawRect(0,0,getWidth(),getHeight()*2/3f, bgPaint);
    //线条画笔
    Paint darkPaint =new Paint();
    darkPaint.setColor(getResources().getColor(R.color.dark));
    Paint hilitePaint =new Paint();
    hilitePaint.setColor(getResources().getColor(R.color.hilite));
    Paint lightPaint =new Paint();
    lightPaint.setColor(getResources().getColor(R.color.light));
    //绘制线条
    for(int i=0;i<9;i++){
      canvas.drawLine(0, i*height,getWidth(),i*height,lightPaint);
      canvas.drawLine(0, i*height+1,getWidth(),i*height+1,hilitePaint);
      canvas.drawLine(i*width, 0,i*width,getWidth()+width*0.4f,lightPaint);
      canvas.drawLine(i*width+1,0,i*width+1,getWidth()+width*0.4f,hilitePaint);
      if(i%3==0){
        canvas.drawLine(0, i*height,getWidth(),i*height,darkPaint);
        canvas.drawLine(0, i*height+3,getWidth(),i*height+3,hilitePaint);
        canvas.drawLine(i*width, 0,i*width,getWidth()+width*0.4f,darkPaint);
        canvas.drawLine(i*width+3, 0,i*width+3,getWidth()+width*0.4f,hilitePaint);
      }
    }
    //绘制数字
    Paint numberPaint =new Paint();
    numberPaint.setColor(Color.BLACK);
    numberPaint.setStyle(Paint.Style.STROKE);
    numberPaint.setTextSize(height*0.75f);
    numberPaint.setTextAlign(Align.CENTER);

    //调节文字居中
    FontMetrics fMetrics=numberPaint.getFontMetrics();
    float x=width/2;
    float y=height/2-(fMetrics.ascent+fMetrics.descent)/2;
    for(int i=0;i<9;i++)
    {
      for(int j=0;j<9;j++)
      {
        canvas.drawText(mGame.getNumber(i+1, j+1), i*width+x, y+j*height, numberPaint);
      }
    }

  }
  //触摸事件
  @Override
  public boolean onTouchEvent(MotionEvent event) {
    int x=(int)(event.getX()/width);
    int y=(int)(event.getY()/height);
    if(x<=8 && y<=8){ //判断点击的是否是游戏界面
      int []t=mGame.getUsed(x, y);
      selectX=x;
      selectY=y;
      MyDialog mDialog=new MyDialog(getContext(), t, this); //调用自定义Dialog
      mDialog.show();
    }
    return super.onTouchEvent(event);
  }
  public void setTitle(int i){
    mGame.setTitle(i,selectX,selectY);
    invalidate(); //每次填写一个数 都要重新进行绘制
    mGame.youWin();
  }
}

2.新建MyGame类：

package com.example.administrator.shudugame;

import android.content.Context;
import android.content.DialogInterface;
import android.support.v7.app.AlertDialog;

/**
 * Created by Administrator on 2016/9/19.
 */
public class MyGame {

  Context context;
  String data="008309100" +
      "900060004" +
      "007504800" +
      "036000540" +
      "001000600" +
      "042000970" +
      "005907300" +
      "600010008" +
      "004608200";
  int numbers[][] =new int[9][9];
  public MyGame(){
    //初始化data
    for(int i=0;i<9;i++)
      for(int j=0;j<9;j++)
      {
        numbers[i][j]=data.charAt(i+j*9)-'0'; //字符转化为整形
      }
  }
  //得到值
  public String getNumber(int x,int y){
    if(numbers[x-1][y-1]==0)
      return "";
    else
      return ""+numbers[x-1][y-1];
  }
  //算出已经被用的数字
  public int[] getUsed(int x,int y){
    int c[]=new int[9];
    //x列
    for(int i=0;i<9;i++)
    {
      if(numbers[x][i]!=0)
      {
        c[numbers[x][i]-1]=numbers[x][i];
      }
    }
    //y排
    for(int i=0;i<9;i++)
    {
      if(numbers[i][y]!=0)
      {
        c[numbers[i][y]-1]=numbers[i][y];
      }
    }
    //小九宫格
    x=(x/3)*3;
    y=(y/3)*3;
    for(int i=0;i<9;i++)
    {
      if(numbers[x+i%3][y+i/3]!=0)
      {
        c[numbers[x+i%3][y+i/3]-1]=numbers[x+i%3][y+i/3];
      }
    }
    return c;
  }
  //设置选定的数字
  public void setTitle(int i,int x,int y){
    numbers[x][y]=i;
  }
  //判断游戏结束
  public void youWin(){
    int t=0;
    for (int i=0;i<9;i++){
      for (int j=0;j<9;j++){
        if (numbers[i][j]!=0){
           t++;
        }
      }
    }
    if (t==81){
      AlertDialog.Builder builder=new AlertDialog.Builder(context);
      builder.setTitle("Tips")
          .setMessage("You Win !")
          .setPositiveButton("Restart", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {

            }
          })
          .setNegativeButton("Exit", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
              System.exit(0);
            }
          }).show();
    }
  }
}

3.自定义Dialog类：

package com.example.administrator.shudugame;

/**
 * Created by Administrator on 2016/9/19.
 */
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;

public class MyDialog extends Dialog{

  MyView mView;
  View keys[]=new View[9];
  int []used=new int[9];

  //传入已经使用过的数字
  public MyDialog(Context context, int[] useed, MyView m) {
    super(context);
    this.mView=m;
    this.used=useed;

  }
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //设置标题
    setTitle("可选数字");
    //设置布局文件
    setContentView(R.layout.table);
    int id[]=new int[]{R.id.bt1,R.id.bt2,R.id.bt3,R.id.bt4,
        R.id.bt5,R.id.bt6,R.id.bt7,R.id.bt8,R.id.bt9};
    for(int i=0;i<9;i++)
    {
      final int t=i+1;
      keys[i]=findViewById(id[i]);
      keys[i].setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
          mView.setTitle(t);
          dismiss(); //取消对话框
        }
      });
    }
    for(int i=0;i<9;i++)
    {
      if(used[i]!=0)
        keys[used[i]-1].setVisibility(View.INVISIBLE); //将不可使用的数字对应的Button设置为隐藏
    }
  }
}

4.在MainActivity中，在onCreate()方法： 更改：setContentView(R.layout.activity_main); 为 setContentView(new MyView(this,attrs));

5.新建table.xml：
