Android开发实现的简单五子棋游戏示例

/* * 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 <at> gmail.com * * *///----------------------//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.TextView;//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.id.gobangview);  gbv.setTextView((TextView)this.findViewById(R.id.text));}
