这篇"Android怎么实现数独游戏开发"文章的知识点大部分人都不太理解，所以小编给大家总结了以下内容，内容详细，步骤清晰，具有一定的借鉴价值，希望大家阅读完这篇文章能有所收获，下面我们一起来看看这篇"Android怎么实现数独游戏开发"文章吧。
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
package com.dw.gamesuduku;import android.app.Activity;import android.os.Bundle;public class About extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.about); }}三、逻辑实现1
package com.dw.gamesuduku;import android.app.Activity;import android.app.Dialog;import android.os.Bundle;import android.util.Log;import android.view.Gravity;import android.widget.Toast;public class Game extends Activity { private static final String TAG="Sudoku"; private static final String PREF_PUZZLE="puzzle"; protected static final int DIFFICULTY_CONTINUE=-1; public static final String KEY_DIFFICULTY="difficulty"; public static final int DIFFICULTY_EASY=0; public static final int DIFFICULTY_MEDIUM=1; public static final int DIFFICULTY_HARD=2; private int puzzle[]=new int[9*9]; private PuzzleView puzzleView; //三种游戏模式 private static final String easyPuzzle="360000000004230800000004200"+ "070460003820000014500013010"+ "001900000007048300000000045"; private static final String mediumPuzzle="650000070000506000014000005"+ "007009000002314700000700800"+ "500000630000201000030000097"; private static final String hardPuzzle="009000000080605020501078000"+ "000000700706040102004000000"+ "000720903090301080000000600"; private final int used[][][]=new int[9][9][]; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); Log.e(TAG, "onCreate"); int diff=getIntent().getIntExtra(KEY_DIFFICULTY, DIFFICULTY_EASY); puzzle=getPuzzle(diff); calculateUsedTiles(); puzzleView=new PuzzleView(this); setContentView(puzzleView); puzzleView.requestFocus(); //if the activity is restarted ,do a continue next time getIntent().putExtra(KEY_DIFFICULTY, DIFFICULTY_CONTINUE); } @Override protected void onPause() { // TODO Auto-generated method stub super.onPause(); Music.stop(this); //Save the current puzzle getPreferences(MODE_PRIVATE).edit().putString(PREF_PUZZLE, toPuzzleString(puzzle)).commit(); } @Override protected void onResume() { // TODO Auto-generated method stub super.onResume(); Music.play(this, R.raw.game); } protected int[] getUsedTiles(int x,int y){ return used[x][y]; } private void calculateUsedTiles() { // TODO Auto-generated method stub for (int x = 0; x < 9; x++) { for (int y = 0; y < 9; y++) { used[x][y]=calculateUsedTiles(x,y); } } } private int[] calculateUsedTiles(int x, int y) { // TODO Auto-generated method stub int c[]=new int[9]; //horizontal for(int i=0;i<9;i++){ if(i==y) continue; int t=getTitle(x, i); if(t!=0) c[t-1]=t; } //vertical for(int i=0;i<9;i++){ if(i==x) continue; int t=getTitle(i, y); if(t!=0) c[t-1]=t; } //same cell block int startx=(x/3)*3; int starty=(y/3)*3; for(int i=startx;i五、背景音乐
package com.dw.gamesuduku;import android.content.Context;import android.media.MediaPlayer;public class Music { private static MediaPlayer mp=null; //stop old song and start a new song public static void play(Context context,int resource){ stop(context); if(Settings.getMusic(context)){ mp=MediaPlayer.create(context, resource); mp.setLooping(true); mp.start(); } } //stop the music public static void stop(Context context) { // TODO Auto-generated method stub if(mp!=null){ mp.stop(); mp.release(); mp=null; } }}六、逻辑实现2
