Android游戏之数独游戏开发

2023-09-19 07:07:06 62

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：

packagecom.example.administrator.shudugame;

/**
*CreatedbyAdministratoron2016/9/19.
*/

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

publicclassMyViewextendsView{

publicMyView(Contextcontext,AttributeSetattrs){
super(context,attrs);
}
//方格长宽
floatwidth;
floatheight;
//选定的坐标
intselectX;
intselectY;
MyGamemGame=newMyGame();

//获得屏幕尺寸
@Override
protectedvoidonSizeChanged(intw,inth,intoldw,intoldh){
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
protectedvoidonDraw(Canvascanvas){
super.onDraw(canvas);
//画背景
PaintbgPaint=newPaint();
bgPaint.setColor(getResources().getColor(R.color.bg));
canvas.drawRect(0,0,getWidth(),getHeight()*2/3f,bgPaint);
//线条画笔
PaintdarkPaint=newPaint();
darkPaint.setColor(getResources().getColor(R.color.dark));
PainthilitePaint=newPaint();
hilitePaint.setColor(getResources().getColor(R.color.hilite));
PaintlightPaint=newPaint();
lightPaint.setColor(getResources().getColor(R.color.light));
//绘制线条
for(inti=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
PaintnumberPaint=newPaint();
numberPaint.setColor(Color.BLACK);
numberPaint.setStyle(Paint.Style.STROKE);
numberPaint.setTextSize(height*0.75f);
numberPaint.setTextAlign(Align.CENTER);

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

}
//触摸事件
@Override
publicbooleanonTouchEvent(MotionEventevent){
intx=(int)(event.getX()/width);
inty=(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;
MyDialogmDialog=newMyDialog(getContext(),t,this);//调用自定义Dialog
mDialog.show();
}
returnsuper.onTouchEvent(event);
}
publicvoidsetTitle(inti){
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：

packagecom.example.administrator.shudugame;

importandroid.content.Context;
importandroid.content.DialogInterface;
importandroid.support.v7.app.AlertDialog;

/**
*CreatedbyAdministratoron2016/9/19.
*/
publicclassMyGame{

Contextcontext;
Stringdata="008309100"+
"900060004"+
"007504800"+
"036000540"+
"001000600"+
"042000970"+
"005907300"+
"600010008"+
"004608200";
intnumbers[][]=newint[9][9];
publicMyGame(){
//初始化data
for(inti=0;i<9;i++)
for(intj=0;j<9;j++)
{
numbers[i][j]=data.charAt(i+j*9)-'0';//字符转化为整形
}
}
//得到值
publicStringgetNumber(intx,inty){
if(numbers[x-1][y-1]==0)
return"";
else
return""+numbers[x-1][y-1];
}
//算出已经被用的数字
publicint[]getUsed(intx,inty){
intc[]=newint[9];
//x列
for(inti=0;i<9;i++)
{
if(numbers[x][i]!=0)
{
c[numbers[x][i]-1]=numbers[x][i];
}
}
//y排
for(inti=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(inti=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];
}
}
returnc;
}
//设置选定的数字
publicvoidsetTitle(inti,intx,inty){
numbers[x][y]=i;
}
//判断游戏结束
publicvoidyouWin(){
intt=0;
for(inti=0;i<9;i++){
for(intj=0;j<9;j++){
if(numbers[i][j]!=0){
t++;
}
}
}
if(t==81){
AlertDialog.Builderbuilder=newAlertDialog.Builder(context);
builder.setTitle("Tips")
.setMessage("YouWin!")
.setPositiveButton("Restart",newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){

}
})
.setNegativeButton("Exit",newDialogInterface.OnClickListener(){
@Override
publicvoidonClick(DialogInterfacedialog,intwhich){
System.exit(0);
}
}).show();
}
}
}

3.自定义Dialog类：

packagecom.example.administrator.shudugame;

/**
*CreatedbyAdministratoron2016/9/19.
*/
importandroid.app.Dialog;
importandroid.content.Context;
importandroid.os.Bundle;
importandroid.view.View;

publicclassMyDialogextendsDialog{

MyViewmView;
Viewkeys[]=newView[9];
int[]used=newint[9];

//传入已经使用过的数字
publicMyDialog(Contextcontext,int[]useed,MyViewm){
super(context);
this.mView=m;
this.used=useed;

}
@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
//设置标题
setTitle("可选数字");
//设置布局文件
setContentView(R.layout.table);
intid[]=newint[]{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(inti=0;i<9;i++)
{
finalintt=i+1;
keys[i]=findViewById(id[i]);
keys[i].setOnClickListener(newView.OnClickListener(){

publicvoidonClick(Viewv){
mView.setTitle(t);
dismiss();//取消对话框
}
});
}
for(inti=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：
