大约一个月前，我刚刚完成了一个应用程序，它使用了我认为最“灵活”的解决方案。 （呵呵呵呵）
（第一个答案：）
如果您熟悉/熟悉（良好的）数据库设计，您可以设计一个 SQLite 数据库，允许您添加和修改您正在使用的所有数据。
（如果没有，我建议：
http://www.amazon.com/The-Art-SQL-Stephane-Faroult/dp/0596008945/ref=sr_1_14?s=books&ie=UTF8&qid=1336262973&sr=1-14
或
http://www.amazon.com/SQL-Demystified-Andrew-Oppel/dp/0072262249/ref=sr_1_1?s=books&ie=UTF8&qid=1336263052&sr=1-1
...这篇文章需要的时间比我预期的要长！嘿嘿嘿;P =D)
基本上是这样的：
类别表（例如体积、长度等）和另一个用于特定名称/值对的表（“km 到 mi”= 0.62137119224 [每个在单独的列中]）以及类别 id 列。
然后在您的主页上，您的 init() 为类别表创建一个 DAO（数据访问对象 [如果您还不知道，请研究一下]），然后将类别提取到 ArrayCollection 并将其设置为 dataProvider在您的类别列表中（在主视图上 - 或任何地方）。
（第二个答案：）
让类别列表的更改处理程序获取 selectedItem 并将其作为 navigator.pushView() 中的第二个参数传递。这会将 VO（值对象——如果您不知道，则另作研究）作为“数据”属性发送到新视图。
在“推送视图”中，使用您的 creationComplete 处理程序来“捕获”（使用）数据变量，该变量将包含类别的名称和 ID。为 values 表创建一个新的 DAO，然后使用 data.id 值加载具有该类别 ID 的所有值。然后将新的 ArrayCollection 设置为值列表的 dataProvider。
然后创建另一个视图以选择要以相同方式编辑的值。除了该“流程”中的最终视图将是一个包含类别、名称和值（带有保存和取消按钮）输入的表单，该表单也将填充适当的数据。 （注意：使用类别 DAO 来获取类别的名称，以便在更改类别时可以使用类别名称和 ID。
...那么只需在该视图上实现插入和更新方法以及每个 DAO 中所需的 SQL 和方法即可。
您可以使用 Lita (http://www.dehats.com/drupal/?q=node/58) 构建、设计和预填充您的数据库。
...我可能会带回一些不错的示例代码/文件（如果我记得的话）
我为那些正在阅读的人做了一些例子，希望我能...
