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]
<span style="font-size:18px;color:#3333ff;">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)); } }</span> 2、牌桌页面[java]
<span style="color:#3333ff;">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 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： 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; } } } </span>
3、相关实体类
扑克牌类：
[java]
<span style="font-size:18px;color:#3333ff;">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; } } } </span>玩家类：
[java]
<span style="font-size:18px;color:#3333ff;">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); } } </span>
PS：斗地主还是可以做成很复杂的。相关图片
