本文实例讲述了Android开发实现的简单五子棋游戏。分享给大家供大家参考，具体如下：

我刚刚在Android上写的一个五子棋的小程序，在这里跟大家分享一下。

写完以后感觉Android的SDK，虽然也是使用Java的，但是跟Java ME还是有很大不一样。

首先就是Android的SDK没有实现所有的Java ME标准，原来运行在KJava上的应用程序是不能在Android上直接跑的。

另外就是Android的SDK有大量的API是Android自己的，需要开发人员去了解。

Android的开发框架也跟别的不一样，需要学习一下。

这个五子棋游戏是我参照Android 的Snake这个Demo还有别的例子，加上自己的需求写出来的。

其中实现了棋盘、下棋、判断输赢、重新开局等功能。目前暂时没有实现机器智能走棋子的功能。

Android的触屏功能是比较好用的，前一段时间见人演示的G1，触屏很好用，而且Android的“Window” 窗、"Shade"帘加上触摸，显得很炫。

呃，这个五子棋，也是用触摸屏实现走棋的。点一下棋盘的位子，把棋子落到棋盘上。

先贴个图看看效果吧。

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 <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));}

里面的R.id.gobangview是在res中定义的View。

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <lixinsong.game.gobang.GobangView android:id="@+id/gobangview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="aaaaa" tileSize="24" /> <RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" > <TextView android:id="@+id/text" android:text="hahahhaha" android:visibility="visible" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:gravity="center_horizontal" android:textColor="#ffff0000" android:textStyle="bold" android:textSize="24sp" /> </RelativeLayout></FrameLayout>
