[转]Android开发-一个简单的五子棋游戏

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"
