简单七巧板源码
自己以前写过一个简单的七巧板，功能不完善，玩玩可以，不要太认真，分享下。
主程序入口
qiqiao.java
/* * @description: * main qiqiao activity * @author: warren * @email: warrenqin@hotmail.com * @date: 2012.1.10 */ package com.my.Qiqiao; import com.my.game.GameView; import android.app.Activity; import android.os.Bundle; import android.view.ViewGroup.LayoutParams; import android.widget.LinearLayout; public class Qiqiao extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); /* 设置Activity要显示的布局为(R.layout.main) */ //setContentView(R.layout.main); LinearLayout layout = new LinearLayout(this); layout.setOrientation(LinearLayout.VERTICAL); LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT); layout.addView(new GameView(this), new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); setContentView(layout, layoutParams); } }
整个代码结构可以分为三部分：控制显示的，控制逻辑的，控制数据的 ，真惭愧具体细节都记不太清楚了。
GameView.java 是整个显示的入口

PhysicsPara.java定义基本的图形要素，中心点坐标、 相对于基准方向的 角度、图形内切圆半径，有了它们就很容的构造出我们所需要的图形了。

DrawPhysics.java 定义了不同图形的实现，也就是说四边形、三角形、平行四边形长什么样子都是由着个文件决定的。

代码就这些了，我是在M9上调试的，没有在其他机器上试过。
操作方式：双击可旋转，单击选择后拖动
注意：
如果要在其他机器上运行请自行修改DataPhysics.java 中的相关参数： baseLength 决定所有图形的大小、DataPhysics()中初始化了七个图形的初始位置（如果显示少了图形，修改这里）。
问题：没有做边界检测，没有做翻转、双击旋转的角度是固定的 、其他
