1. 介绍
Lua是游戏、软件开发中脚本语言的首选。Android中的主要作用是替代json,提升了性能。
fastjson包2.5MB,lua仅需要107KB,

lua脚本语言中一个独特的数据类型就是表,表其实就是java中的map、哈希表,比如说下面一个表:
T1={}--定义一个空表 T1[1]=10--定义表的内容 T1["John"]={Age=27,Gender="Male"}
而每一个脚本文件实际上就是一个大表,每一个变量、方法都是表的成员,因此脚本的变量默认都是全局的,而且也可以
定以方法为变量,kahlua正是依据这个概念来的。
2. 使用kahlua
kahlua最初是为J2ME设计的,现在已经扩展到J2SE,项目地址是http://code.google.com/p/kahlua/,在这里可以
下载到源代码及编译好的jar包。kahlua可以识别*.lua及*.lbc文件,*.lbc是编译后的lua文件,项目中一般使用
这种文件,因为不会泄露lua文件的内容。可以到http://www.lua.org上下载一个lua的运行环境,安装后会自动添加
安装路径到系统变量,此时在cmd中运行luac程序就可以编译脚本,命令是luac -o f.lbc d:/f.lua
3. 参数结构

},responseCode = "0",}4. 解析
LuaTable luaTable = LuaTableUtil.stringToLuaTable(luaDataString.getBytes());
//获取参数的方法
String mRespCode2 = LuaTableUtil.getString(luaTable, "responseCode", "");
//获取数组的方法
String mAppinfoList = LuaTableUtil.getArrayList(LuaTableUtil.getLuaTable(luaTable, "appinfoList")).toString();
//解析数组，转成json
Object obj = luaTable.rawget("appinfoList");
Vector<LuaTable> array = LuaTableUtil.getArray((LuaTable) obj);
if (array == null || array.size() <= 0) return;
ArrayList<LuaBean> arrayList = new ArrayList<>();
for (LuaTable mLuaTable : array) {
LuaBean luaBean = new LuaBean();
luaBean.setAppDesc((String) mLuaTable.rawget("appDesc"));
