Android应用实践之数独游戏开发

2023-09-19 06:39:05 76

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。拼图是九宫格（即3格宽×3格高）的正方形状，每一格又细分为一个九宫格。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。不少教育者认为数独是锻炼脑筋的好方法，上外语阅读课的时候外教老师就很喜欢带我们玩这个，乐此不疲，老外的教学方式还是很受欢迎的。但是每次玩这个游戏的时候都要发一张数独游戏卡，嫌麻烦，就想着写一个demo放自己手机上，想想那个时候真是好奇心爆棚，碰上很火爆的小游戏都想整一个DIY的Demo，叨叨够了，哈哈，上源码。

一、界面布局

1.主界面

2.数字键盘布局

3.游戏提示布局

二、游戏提示类

packagecom.dw.gamesuduku;

importandroid.app.Activity;
importandroid.os.Bundle;
publicclassAboutextendsActivity{

@Override
protectedvoidonCreate(BundlesavedInstanceState){
//TODOAuto-generatedmethodstub
super.onCreate(savedInstanceState);
setContentView(R.layout.about);
}
}

三、逻辑实现1

packagecom.dw.gamesuduku;

importandroid.app.Activity;
importandroid.app.Dialog;
importandroid.os.Bundle;
importandroid.util.Log;
importandroid.view.Gravity;
importandroid.widget.Toast;
publicclassGameextendsActivity{
privatestaticfinalStringTAG="Sudoku";
privatestaticfinalStringPREF_PUZZLE="puzzle";
protectedstaticfinalintDIFFICULTY_CONTINUE=-1;

publicstaticfinalStringKEY_DIFFICULTY="difficulty";
publicstaticfinalintDIFFICULTY_EASY=0;
publicstaticfinalintDIFFICULTY_MEDIUM=1;
publicstaticfinalintDIFFICULTY_HARD=2;

privateintpuzzle[]=newint[9*9];
privatePuzzleViewpuzzleView;
//三种游戏模式
privatestaticfinalStringeasyPuzzle="360000000004230800000004200"+

privatestaticfinalStringhardPuzzle="009000000080605020501078000"+
"000000700706040102004000000"+
"000720903090301080000000600";

privatefinalintused[][][]=newint[9][9][];
@Override
protectedvoidonCreate(BundlesavedInstanceState){
//TODOAuto-generatedmethodstub
super.onCreate(savedInstanceState);
Log.e(TAG,"onCreate");
intdiff=getIntent().getIntExtra(KEY_DIFFICULTY,DIFFICULTY_EASY);
puzzle=getPuzzle(diff);
calculateUsedTiles();

puzzleView=newPuzzleView(this);
setContentView(puzzleView);
puzzleView.requestFocus();
//iftheactivityisrestarted,doacontinuenexttime
getIntent().putExtra(KEY_DIFFICULTY,DIFFICULTY_CONTINUE);
}


@Override
protectedvoidonPause(){
//TODOAuto-generatedmethodstub
super.onPause();
Music.stop(this);
//Savethecurrentpuzzle
getPreferences(MODE_PRIVATE).edit().putString(PREF_PUZZLE,toPuzzleString(puzzle)).commit();
}

@Override
protectedvoidonResume(){
//TODOAuto-generatedmethodstub
super.onResume();
Music.play(this,R.raw.game);
}

protectedint[]getUsedTiles(intx,inty){
returnused[x][y];
}

privatevoidcalculateUsedTiles(){
//TODOAuto-generatedmethodstub
for(intx=0;x<9;x++){
for(inty=0;y<9;y++){
used[x][y]=calculateUsedTiles(x,y);
}
}
}
privateint[]calculateUsedTiles(intx,inty){
//TODOAuto-generatedmethodstub
intc[]=newint[9];
//horizontal

for(inti=0;i<9;i++){
if(i==y)
continue;
intt=getTitle(x,i);
if(t!=0)
c[t-1]=t;
}
//vertical

for(inti=0;i<9;i++){
if(i==x)
continue;
intt=getTitle(i,y);
if(t!=0)
c[t-1]=t;
}
//samecellblock
intstartx=(x/3)*3;
intstarty=(y/3)*3;
for(inti=startx;i
五、背景音乐
packagecom.dw.gamesuduku;

importandroid.content.Context;
importandroid.media.MediaPlayer;

publicclassMusic{
privatestaticMediaPlayermp=null;
//stopoldsongandstartanewsong
publicstaticvoidplay(Contextcontext,intresource){
stop(context);
if(Settings.getMusic(context)){
mp=MediaPlayer.create(context,resource);
mp.setLooping(true);
mp.start();
}
}
//stopthemusic

//TODOAuto-generatedmethodstub
if(mp!=null){
mp.stop();
mp.release();
mp=null;
}
}
}

break;
}
}
@Override

super.onResume();
Music.play(this,R.raw.welcome);
}
@Override

returntrue;
}

@Override

}
returnfalse;
}

privatevoidopenNewGameDialog(){

intent.putExtra(Game.KEY_DIFFICULTY,i);
startActivity(intent);
}
}
