Android开发实现的简单五子棋游戏示例

时间：2021-01-30 10:26:35 | 栏目：Android代码 | 点击：次

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：

/*

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"
