我们首先把数独游戏的布局，自定义View和初始化数字给完成；
我们把画笔的颜色写进color.xml里

架构.jpg

• color.xml(画笔颜色)

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="background">#ffe6f0ff</color>
    <color name="hilite">#ffffffff</color>
    <color name="light">#64c6d4ef</color>
    <color name="dark">#6456648f</color>
</resources>

• MainActivity.java(引用自定义View布局)

/**
 * 数独游戏开发
 * @author dandan
 *
 */
public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
//        setContentView(R.layout.activity_main);
        setContentView(new MyView(this));
    }
}

• MyView.java(自定义View)

/**
 * 数独游戏开发
 * @author dandan
 *
 */
public class MyView extends View{

    private float widht,height;
    private Game game = new Game();
    //构造方法
    public MyView(Context context) {
        super(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);
            canvas.drawLine(i*widht+1,0,i*widht+1, getHeight(), hilitepaint);
        }
        //画外面的最清楚的4个深色的线
        for(int i=0;i<9;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);
            canvas.drawLine(i*widht+1,0,i*widht+1, getHeight(), hilitepaint);
        }
        //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.getStringTile(i,j), i*widht+x,j*height+y, numpaint);
            }
        }
        super.onDraw(canvas);
    }
}

• Game.java(游戏初始化数字)

/**
 * 数独游戏开发
 * @author dandan
 *
 */
public class Game {
    //數獨初始化數據
    private final String data = "360000000004230800000004200"+
                                "070460003820000014500013020"+
                                "001900000007048300000000045";
    private int[] shuduku = new int[9*9];
    
    //根據一個字符串數據，生成一個整型數組
    protected int[] fromString(String src){
        int[] shudu = new int[src.length()];
        for(int i=0;i<src.length();i++){
            shudu[i] = src.charAt(i)-'0';
        }
        return shudu;
    }
    public Game(){
        shuduku = fromString(data);
    }
    //根據九宮格的坐標，返回坐標所對應的數字
    private int getTile(int x,int y){
        
        return shuduku[y*9+x];
    }
    //得到字符串
    public String getStringTile(int x,int y){
        int v = getTile(x,y);
        if(v==0){
            return "";
        }
        return String.valueOf(v);
    }
}
