发一个Android斗地主游戏的牌桌实现。

为了节约内存资源，每张扑克牌都是剪切形成的，当然这也是当前编程的主流方法。

1、主Activity

package com.bison;  
  
import android.app.Activity;  
import android.content.pm.ActivityInfo;  
import android.os.Bundle;  
import android.view.Window;  
import android.view.WindowManager;  
  
/** 
 * 求某公司包养 
 *  
 * @author Bison 
 *  
 */  
public class PukeActivity extends Activity {  
    /** Called when the activity is first created. */  
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        // 这个事隐藏标题栏，不解释   
        requestWindowFeature(Window.FEATURE_NO_TITLE);  
        // 隐藏状态栏，你懂的   
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,  
                WindowManager.LayoutParams.FLAG_FULLSCREEN);  
        /* 
         * 开始有考虑使屏幕上扑克的排列随屏幕的分辨率变动 结果貌似不好做，注释掉了 Display display = 
         * getWindowManager().getDefaultDisplay(); int screenWidth = 
         * display.getWidth(); int screenHeight = display.getHeight(); 
         */  
  
        // 使用代码锁定横屏   
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);  
        // setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);这个是竖屏   
        setContentView(new GameView(this));  
    }  
}
2、牌桌页面

import android.view.SurfaceView;  
  
import com.bison.utils.Person;  
  
/**

 *  
 * 扑克图片来源,和牌桌背景在文章的下面。 扑克背面图等我没上传，玩家自行百度

3、相关实体类

扑克牌类：

package com.bison.utils;  
  
import java.util.Random;  
  
/** 
 * 生成一副洗好的牌，并且 设计为单例模式 
 *

    }

        if (cardsInstance == null) {  
            cardsInstance = new Cards();  
        }  
        return cardsInstance;  
    }  
  
    /** 给54张扑克牌赋值 ：1~54 */  
    private void setPuke() {  
        for (int i = 0; i < 54; i++) {  
            pukes[i] = i + 1;  
        }  
    }  
  
    /** 洗牌 */  
    private void shuffle() {  
        Random rdm = new Random();  
        for (int i = 0; i < 54; i++) {  
            // random.nextInt();是个前闭后开的方法：0~53   
            int rdmNo = rdm.nextInt(54);  
            int temp = pukes[i];  
            pukes[i] = pukes[rdmNo];  
            pukes[rdmNo] = temp;  
        }  
    }  
}  

玩家类：

                    person3[j] = pukes[k++];  
                }  
                // 将其排序   
                sort(person3);  
            }  
        }  
  
        threePukes[0] = pukes[51];

    }  
  
    /** 对每个玩家手里的牌排序:使用冒泡排序 */
