【移动应用开发技术】Android怎么开发数独游戏

这篇文章给大家分享的是有关Android怎么开发数独游戏的内容。在下觉得挺实用的，因此分享给大家做个参考，一起跟随在下过来看看吧。

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;

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);

canvas.drawLine(i*width+3,

}

}

//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

{

canvas.drawText(mGame.getNumber(i+1,

j+1),

i*width+x,

}

}

}

//触摸事件

@Override

public

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;

/**

*

on

*/

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(newMyView(this,attrs));5.新建table.xml：<?xml

version="1.0"

encoding="utf-8"?>

<TableLayout

xmlns:android="/apk/res/android"

android:orientation="vertical"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:stretchColumns="*"

>

<TableRow

android:id="@+id/row1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

>

<Button

android:id="@+id/bt1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="1"

/>

<Button

android:id="@+id/bt2"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="2"

/>

<Button

android:id="@+id/bt3"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="3"

/>

</TableRow>

<TableRow

android:id="@+id/row2"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

>

<Button

android:id="@+id/bt4"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="4"

/>

<Button

android:id="@+id/bt5"

android:layout_width="wrap_content"

android:layout_height="wrap_content"
