我是多么的Java应该已经学会尝试的Andr​​oid编程之前？ [英] How much Java should I have learnt before trying Android programming?

问题描述

我一直在寻求的Andr​​oid初学者学习书籍，当然发现我应该先学习Java。于是，我开始学习Java和我现在很舒服对象，类，继承，接口，只是移动到布局在Swing和摇摆功能。但我开始怀疑....我不够了解Java的吗？我可以开始编程机器人吗？

当然，我可以继续下去在Java中，但已跃跃欲试，开始编写Android应用程序。

任何明确的答案，在这里我是多么的Java需要了解Android的过吗？

太感谢了！

解决方案

  

做我不够了解Java的吗？的

是

  

我就可以开始编程机器人吗？的

是

  

多少的Java我需要了解Android的过吗？的

基础的完整的了解是可取的。

具体有以下内容：

• 在声明和访问控制
• ObjectOrientation
• 分配
• 符
• 流量控制，异常和断言
• 字符串，I / O，格式化和解析
• 泛型和集合
• InnerClasses
• 主题

但如果你已经知道的基本知识（类，对象，继承，接口），我觉得你行启动。

您不需要了解具体的库（如Swing或其他），因为你不会使用他们的Andr​​oid。

I have been seeking beginner learning books in Android, and of course found out that I should learn Java first. So I began studying Java and now I am quite comfortable with objects, classes, inheritance, interfaces, and just moved onto Layouts in Swing as well as Swing Features. But I am starting to wonder.... do I know enough about Java now? Can I start programming Android yet?

Of course I can keep going in Java, but have been itching to begin programming Android apps.

Any definitive answer here about how much Java I need to know before Android?

Thanks so much!

解决方案

do I know enough about Java now?

Yes

Can I start programming Android yet?

Yes

how much Java I need to know before Android?

A complete understanding of the basics would be desirable.

Specifically the following topics:

• Declarations and Access Control
• ObjectOrientation
• Assignments
• Operators
• Flow Control, Exceptions, and Assertions
• Strings, I/O, Formatting, and Parsing
• Generics and Collections
• InnerClasses
• Threads

But if you know already the basics ( classes, objects, inheritance, interfaces ) I think you're ok to start.

You don't need to learn specific libraries ( like swing, or others ) because you won't use them in Android.
