本文提供了一个Android斗地主游戏的牌桌实现方法，通过剪切扑克牌图片以节约内存，并详细介绍了主Activity、牌桌页面的代码实现，包括牌桌背景、扑克牌的绘制和布局。同时，还涉及到玩家手牌的处理和排序逻辑。

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;
public class PukeActivity extends Activity {
@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);
// 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

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;
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);
}
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);
}
}
}
}
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);
