1、Android开发-一个简单的五子棋游戏好了，下面直接贴代码：/* Five In a Row. (五子棋)* 这是一个简单的五子棋程序，是我自己的一个练习，贴出来跟大家分享。* 希望跟大家一起多交流。 我的GoogleTalk: lixinso */-/TBD:AI，悔棋/-package lixinsong.game.gobang;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.TextVie

2、w;/这是主程序，继承自Activity，实现onCreate方法。：public class gobang extends Activity GobangView gbv; /* Called when the activity is first created. */ Override public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.main); gbv = (GobangView)this.findViewById(R.i

3、d.gobangview); gbv.setTextView(TextView)this.findViewById(R.id.text);里面的R.id.gobangview是在res中定义的View。 /五子棋的Viewpackage lixinsong.game.gobang;import android.content.Context;import android.content.res.Resources;import android.graphics.Bitmap;import android.graphics.Canvas;import android.graphics.Color
