android 桌面斗地主

引用：http://www.2cto.com/kf/201204/126319.html

发一个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

[java]
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

[java]
package com.bison;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Rect;
import android.view.MotionEvent;
import android.view.SurfaceHolder;
import android.view.SurfaceView;

import com.bison.utils.Person;

/**
* 牌桌，会被老婆骂，最好不要上去，你懂的
*
* 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
*
* @author Bison
*
*/
public class GameView extends SurfaceView implements SurfaceHolder.Callback {
private FlushThread thread = null;// 刷帧线程
private Bitmap sourceBitmap = null;// 扑克图片来源
private Bitmap backgroundDesk = null;// 牌桌背景
private Bitmap backgroundPuke = null;// 扑克背面

private final Person person;
private int pukeWidth = 0;// 扑克的宽
private int pukeHeight = 0;// 扑克的高
private int deskWidth = 0;// 牌桌的宽
private int deskHeight = 0;// 牌桌的高
private int left = 0;// 我自己首张牌左距离

public GameView(Context context) {
super(context);
getHolder().addCallback(this);
this.thread = new FlushThread(getHolder(), this);// 实例化线程
initBitmap();// 实例化图片
this.person = new Person();// 实例化Person类
this.left = deskWidth / 2 - (16 * 25 + pukeWidth) / 2;// 左距开始时赋值
}

private void initBitmap() {// 初始化图片
sourceBitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.smallcard);
pukeWidth = sourceBitmap.getWidth() / 14;// 每张扑克的宽高
pukeHeight = sourceBitmap.getHeight() / 4;

backgroundDesk = BitmapFactory.decodeResource(getResources(),
R.drawable.gameback2);

deskWidth = backgroundDesk.getWidth();// 牌桌的宽高
deskHeight = backgroundDesk.getHeight();

backgroundPuke = BitmapFactory.decodeResource(getResources(),
R.drawable.cardback);
}

@Override
protected void onDraw(Canvas canvas) {
// 绘制牌桌
canvas.drawBitmap(backgroundDesk, 0, 0, null);
personPaint(canvas, pukeWidth, pukeHeight);
deskthreePukes(canvas, pukeWidth, pukeHeight);
}

/** 绘制每个玩家手里的牌 */
public void personPaint(Canvas c, int pukeWidth, int pukeHeight) {
Rect src = new Rect();
Rect dst = new Rect();

// 遍历数组
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 17; j++) {
if (i == 0) {// 左手边玩家，不用绘出正面
// src = person.cardRect(person.person1[j], pukeWidth,
// pukeHeight);
// dst.set(10, j * 20, 10 + pukeWidth, j * 20 + pukeHeight);
c.drawBitmap(backgroundPuke, 35, 85, null);
}
if (i == 1) {// 自己
src = person.cardRect(person.person2[j], pukeWidth,
pukeHeight);
dst.set(left + j * 25, this.deskHeight - 20 - pukeHeight,
left + j * 25 + pukeWidth, deskHeight - 20);
c.drawBitmap(sourceBitmap, src, dst, null);
}
if (i == 2) {// 右手边玩家，同样不用绘出正面
// src = person.cardRect(person.person3[j], pukeWidth,
// pukeHeight);
// dst.set(this.screenWidth - 10 - pukeWidth, j * 20,
// this.screenWidth - 10, j * 20 + pukeHeight);
c.drawBitmap(backgroundPuke, deskWidth - 35 - pukeWidth,
85, null);
}
}
}
}

/** 绘制三张底牌 */
private void deskthreePukes(Canvas c, int pukeWidth, int pukeHeight) {
Rect src = new Rect();
Rect dst = new Rect();
for (int i = 0; i < 3; i++) {
src = person.cardRect(person.threePukes[i], pukeWidth, pukeHeight);
dst.set(280 + i * pukeWidth, 12, 280 + (i + 1) * pukeWidth,
12 + pukeHeight);
c.drawBitmap(sourceBitmap, src, dst, null);
}
}

@Override
public boolean onTouchEvent(MotionEvent event) {
// 正在研究点击弹出相应的扑克www.2cto.com
return super.onTouchEvent(event);
}

@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
}

@Override
public void surfaceCreated(SurfaceHolder holder) {
this.thread.setFlag(true);
this.thread.start();
}

@Override
public void surfaceDestroyed(SurfaceHolder holder) {
boolean retry = true;
this.thread.setFlag(false);
while (retry) {
try {
thread.join();
retry = false;
} catch (InterruptedException e) {
e.printStackTrace();
}
}

}

// 刷帧线程，这个不解释，实在看不懂，M我：[email protected]
class FlushThread extends Thread {
private boolean flag = false;
private final int span = 500;
private final GameView gameView;
private final SurfaceHolder holder;

public FlushThread(SurfaceHolder holder, GameView gameView) {
this.gameView = gameView;
this.holder = holder;
}

@Override
public void run() {
Canvas canvas;
while (this.flag) {
canvas = null;
try {
canvas = this.holder.lockCanvas(null);
synchronized (this.holder) {
this.gameView.onDraw(canvas);
}
} finally {
if (canvas != null) {
this.holder.unlockCanvasAndPost(canvas);
}
}

try {
Thread.sleep(span);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}

public boolean isFlag() {
return flag;
}

public void setFlag(boolean flag) {
this.flag = flag;
}

}

}

3、相关实体类

扑克牌类：

[java]
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
*
* @author Bison
*
*/
public class Cards {
// 声明一副扑克牌
public int[] pukes = new int[54];

private static Cards cardsInstance = null;

private Cards() {
setPuke();
shuffle();
}

public static Cards getInstance() {
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：

[java]
package com.bison.utils;

import android.graphics.Rect;

/**
* 这个是玩家的实体类
*
* @author Bison
*
*/
public class Person {
private final Cards mCards = Cards.getInstance();

public int[] person1 = new int[17];
public int[] person2 = new int[17];
public int[] person3 = new int[17];

// 余下三张属于地主的
public int[] threePukes = new int[3];

public Person() {
personHold(mCards.pukes);
}

/** 分牌 */
private void personHold(int[] pukes) {
int k = 0;
for (int i = 0; i < 3; i++) {
if (i == 0) {
for (int j = 0; j < 17; j++) {
person1[j] = pukes[k++];
}
// 将其排序
sort(person1);
}
if (i == 1) {
for (int j = 0; j < 17; j++) {
person2[j] = pukes[k++];
}
// 将其排序
sort(person2);
}
if (i == 2) {
for (int j = 0; j < 17; j++) {
person3[j] = pukes[k++];
}
// 将其排序
sort(person3);
}
}

threePukes[0] = pukes[51];
threePukes[1] = pukes[52];
threePukes[2] = pukes[53];
}

/** 对每个玩家手里的牌排序:使用冒泡排序 */
private void sort(int[] ary) {
for (int i = 0; i < ary.length; i++) {
for (int j = 0; j < ary.length - i - 1; j++) {
if (ary[j] > ary[j + 1]) {
int temp = ary[j];
ary[j] = ary[j + 1];
ary[j + 1] = temp;
}
}
}
}

/**
* 对应扑克所在图片上的位置
* 1 5 9 ………… 53
* 2 6 10 ………… 54
* 3 7 11
* 4 8 12
*/
public Rect cardRect(int cardValue, int width, int height) {
int x = 0, y = 0;
if (cardValue % 4 == 0) {
x = cardValue / 4 - 1;
y = 4;
} else {
x = cardValue / 4;
y = cardValue % 4;
}

int left = x * width;
int top = (y - 1) * height;
int right = (x + 1) * width;
int bottom = (y) * height;
return new Rect(left, top, right, bottom);
}
}

PS：斗地主还是可以做成很复杂的。相关图片
