Android：setcontentview（）中的错误;(Android : Error in setcontentview();)

 如果您有包含您希望使用的类型（类）的源，您可以： 
 
 
 
 创建包含这些类的Java项目 
 
 
 创建一个新的UML项目（包含这些类的UML版本） 
 
 
 将modelLibrary型应用于模型（选择模型，然后单击Stereotypes选项卡上的Apply Stereotypes... ） 
 
 
 创建一个新的转换配置（Java到UML），并将Java源转换为UML（以Java包为源，UML模型为目标） 
 
 
 然后回到原始的UML模型（要添加类型的模型） 
 
 
 
 右键单击您的UML模型，并将刚刚创建的UML模型项目导入为模型库（ Import Model Library...->Library in Workspace ） 
 
 
 为属性选择类型时，您现在应该能够搜索并使用Java项目中的类型！ 
 
 
 当您将UML模型转换为Java时，它应该使用正确的类型和import语句生成，因此您只需要在构建路径上确保这些类。 

If you have the source containing the types (classes) you wish to use you could:
 
 
 
Create a Java project containing those classes
 
 
Create a new UML project (to contain the UML version of those classes)
 
 
Apply the modelLibrary stereotype to the model (select the model, and click Apply Stereotypes... on the Stereotypes tab)
 
 
Create a new transformation configuration (Java to UML), and transform the Java source into UML (with the Java package as the source, and UML model as the target)
 
 
Then back in your original UML model (the one where you want to add the types)
 
 
 
Right-click on your UML model , and import the UML model project you just created as a model library (Import Model Library...->Library in Workspace)
 
 
When you select a type for an attribute, you should now be able to search and use the types in the Java project!
 
 
When you transform your UML model to Java, it should generate with the correct types and import statements, so you'll just have to ensure those classes on the the build path.
