arcgis runtime for android 100.13.0 入门系列，四、番外篇之要素录入结构与规划
在下一篇章就准备到绘制和保存要素的步骤了，在这之前我们需要组织好要素的存储结构。为了各位能上手即用我为大家写了如下代码，结构是按项目来划分，一个项目有多个图层，一个图层有各种自定义设置并且可以添加N个字段，一个字段有多种设置。这样定义好了之后就可以按这个项目结构json结果来生成shp文件了。程序后续会新增shp，geojson，featureServer等操作接口......

在即将到来的绘制和保存要素的篇章之前，我们需要组织好要素的录入结构与规划，为了能快速上手即用我为大家写了这部分的代码逻辑，入口在程序侧边栏项目配置
字段信息编辑完毕回退就会自动保存，在ArcgisAndroid生成一个配置文件，文件名就是项目名，里面的各种信息都是json格式
字段类型有string，int，double。显示样式可以有输入和选择，样式为选择的时候要把默认值内容回车换行一行一个输入，这样在展示的时候就可以用这个换行符来分割得到每一个值让你快速选择来代替重复性的输入。
值得一提的是如何根据json配置文件来动态组装dialog界面的控件呢？这个就需要用代码动态生成了，我弄了个UIGenerator控件工具类，在这做了一些基础的代码控件，可以看到有线性布局，输入框，下拉控件，TextView，还有MaterialCardView。例如我有10个字段我就调用UIGenerator.buildLinearLayout然后指定成为垂直，然后循环调用UIGenerator.buildEditInputView10次就会添加进来父容器buildLinearLayout中，这样就组出了一个线性布局里面有10个输入框了，还可以在buildLinearLayout外面再build一个cardView这样就会出现卡片样式，这下你已经脑补出来了，巧妙吧 ~=。=~
