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：
<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
