1.先上效果图

2.绘制步骤

1.在你要显示的Activity里添加如下几句代码：

public class MainActivity extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

requestWindowFeature(Window.FEATURE_NO_TITLE);

MySurfaceView msv=new MySurfaceView(this);

setContentView(msv);

}

}

将屏幕设成全屏模式，并且无标题形式

创建自己的SurfaceView命名为MySurfaceView用于棋盘的绘制

将屏幕的内容设为MySurfaceView的实例

2. 定义自己的SurfaceView时要注意继承SurfaceView这个控件并实现Callback接口

3. 添加横屏格子数和竖排格子数等参数

4.在构造函数中获得处理绘画的Holder并设置背景图片。

5.在回调函数surfaceCreated里面绘制横线和竖线，以形成棋盘。代码如下：

/**

* 线条格数的划分受所在屏幕分辨率的影响而定

* 本例分辨率参考1024*600【竖屏】

*/

public class MySurfaceView extends SurfaceView implements Callback {

private Bitmap bm;//背景图片

private SurfaceHolder sfh;

private Canvas canvas;

private float tileW,tileH;//每个格子的宽高

private int screenW,screenH;//屏幕的宽高

private static int GRIDW=10,GRIDH=15;//横、纵格子数目

private static int startW=10,startH=22;//左右上下的内缩距离

public MySurfaceView(Context context) {

super(context);

bm=BitmapFactory.decodeResource(getResources(), R.drawable.background);

sfh=this.getHolder();

sfh.addCallback(this);

}

@Override

public void surfaceCreated(SurfaceHolder holder) {

screenW=this.getWidth();

screenH=this.getHeight();

tileW=(screenW-2*startW)/GRIDW;//宽：(600-2*10)/10=58

tileH=(screenH-2*startH)/GRIDH;//高：(1024-2*22)/15=65.33……

canvas=sfh.lockCanvas();

//canvas.drawColor(Color.WHITE);

Paint paint=new Paint();

canvas.drawBitmap(bm, 0, 0, paint);

paint.setColor(Color.GREEN);

paint.setStrokeWidth(1);

paint.setStyle(Style.STROKE);

float startX=0,startY=0;

for(int i=0;i

startX=startW+i*tileW;

startY=startH;

canvas.drawLine(startX, startY, startX, screenH-startH, paint);//(x,y[min])-->(x,y[max])

}

for(int i=0;i

startX=startW;

startY=startH+i*tileH;

canvas.drawLine(startX, startY, screenW-startW, startY, paint);//(x[min],y)-->(x[max],y)

}

if(canvas!=null){

sfh.unlockCanvasAndPost(canvas);

}

}

@Override

public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {

}

@Override

public void surfaceDestroyed(SurfaceHolder holder) {

}

}3.运行即可看到上述效果图了
