数独游戏开发（四）
【数独游戏开发（四）】（通过界面我们知道，点击new Game 进入新游戏 ，点击Continue我们可以吧刚玩的记录重现出来， 点击about 弹出Activity 游戏的介绍， exit代表退出）现在我们在游戏中设置Music+Activity显示+小九宫格数字颜色显示+界面+保存游戏进度+about 具体操作 如下：
- 界面：（有点丑）

以下是修改的Java代码，其它demo不作改动
- MainActivity.java (我们的做法是吧Game.java的demo整合到MainActivity.java里面)
public class MainActivity extends Activity {// 数独初始化数据的基础

}
- MyView.java(做些点击颜色改变)
public class MyView extends View {private float widht, height;
//private Game game = new Game();
private final MainActivity game;
private int selectx, selecty;
private final Rect selectRect = new Rect();
// 构造方法
public MyView(Context context) {
super(context);
this.game=(MainActivity)context;
}// 得到改变的视图宽和高
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
this.widht = w / 9f;
this.height = h / 9f;
super.onSizeChanged(w, h, oldw, oldh);
}// 画视图，⑨宫格
@Override
protected void onDraw(Canvas canvas) {
// 用于生成背景色的画笔(共4种颜色的画笔)
Paint backgroundpaint = new Paint();
// 设置画笔颜色
backgroundpaint.setColor(getResources().getColor(R.color.background));
// 画出背景
canvas.drawRect(0, 0, getWidth(), getHeight(), backgroundpaint);
Paint darkpaint = new Paint();
darkpaint.setColor(getResources().getColor(R.color.dark));
Paint lightpaint = new Paint();
lightpaint.setColor(getResources().getColor(R.color.light));
Paint hilitepaint = new Paint();
hilitepaint.setColor(getResources().getColor(R.color.hilite));
// 下面开始画线
for (int i = 0;
i < 9;
i++) {
// 画横线
canvas.drawLine(0, i * height, getWidth(), i * height, lightpaint);
canvas.drawLine(0, i * height + 1, getWidth(), i * height + 1,
hilitepaint);
// 画竖线
canvas.drawLine(i * widht, 0, i * widht, getHeight(), lightpaint);

}
// 画外面的最清楚的4个深色的线

i++) {
if (i % 3 != 0) {
continue;
}
// 画横线
canvas.drawLine(0, i * height, getWidth(), i * height, darkpaint);
canvas.drawLine(0, i * height + 1, getWidth(), i * height + 1,
hilitepaint);
// 画竖线
canvas.drawLine(i * widht, 0, i * widht, getHeight(), darkpaint);

}
// 框框里添加文本
Paint numpaint = new Paint();
numpaint.setColor(Color.BLACK);
numpaint.setStyle(Paint.Style.STROKE);
numpaint.setTextAlign(Paint.Align.CENTER);
numpaint.setTextSize(height * 0.75f);
// 數字的位置
FontMetrics fm = numpaint.getFontMetrics();
float x = widht / 2;
float y = height / 2 - (fm.ascent + fm.descent) / 2;
for (int i = 0;
i < 9;
i++) {
for (int j = 0;
j < 9;
j++) {
canvas.drawText(game.getTileString(i, j), i * widht + x, j
* height + y, numpaint);
}
}//我们进行绘制小矩形框 ,数字提示颜色
Paint rectPaint = new Paint();
int c[] = {getResources().getColor(R.color.puzzle_hint_0),
getResources().getColor(R.color.puzzle_hint_1),
getResources().getColor(R.color.puzzle_hint_2)};
//生成矩形对象
Rect r = new Rect();
for(int i=0;
i<9;
i++){
for(int j=0;
j<9;
j++){
//我们得到可用数字的个数用moveleft来表示
int moveleft = 9 - game.getUsedTilesByCoor(i, j).length;
//如果可用数字小于3 我们用颜色来提示用户
if(moveleft- Music.java(音乐播放,此方法调用放在需要调用的Activity里)
public class Music {
private static MediaPlayer mp = null;
public static void play(Context context,int resoce){
stop(context);
mp = MediaPlayer.create(context, resoce);
mp.setLooping(true);
mp.start();
}
public static void stop(Context context){
if(mp!=null){
mp.stop();
mp.release();
mp=null;
}
}
}
- OperationActivity.java(首界面)
public class OperationActivity extends Activity implements
OnClickListener{private Button continuee,new_game,about,exit;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.operation);
iviview();
}
private void iviview() {
continuee = (Button) findViewById(R.id.continuee);
new_game = (Button) findViewById(R.id.new_game);
about = (Button) findViewById(R.id.about);
exit = (Button) findViewById(R.id.exit);
continuee.setOnClickListener(this);
new_game.setOnClickListener(this);
about.setOnClickListener(this);
exit.setOnClickListener(this);
}
public void onClick(View v) {
if(v==continuee){
Intent j = new Intent(OperationActivity.this,MainActivity.class);
j.putExtra("contin", -1);
startActivity(j);
}
if(v==new_game){
Intent i = new Intent(OperationActivity.this,MainActivity.class);
startActivity(i);
}
if(v==about){
Intent i_1 = new Intent(OperationActivity.this,AboutActivity.class);
startActivity(i_1);
}
if(v==exit){
finish();
}
}
@Override
protected void onPause() {
super.onPause();
Music.stop(this);
}
@Override
protected void onResume() {
super.onResume();
Music.play(this, R.raw.main);
}
}
- AboutActivity.java(点击About弹出此Activity)
public class AboutActivity extends Activity {private TextView about;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.about);
about = (TextView) findViewById(R.id.about);
about.setText("Sudoku disk is a house, every house is divided into nine compartments. In these eighty-one spaces are given a certain number of known figures and problem solving conditions, the use of logic and reasoning, in other spaces on the 1-9 numbers. "
+ "The 1-9 of each number in each row, "
+ "each column and each palace only once, so called squares.");
}
}
下面就是布局了：（其它布局不变）
- operation.xml(首界面)
- about.xml（关于的布局）
- AndroidManifest.xml(修改首起Activity,配置属性)
- 演示：
