如果您是 Android 开发新手, 您可能听说过 Java, Objective-C, 或斯威夫特. 如果您有兴趣成为移动应用开发人员, 您可能有兴趣了解 Android 编程基础知识. 本课程还将向您介绍 Swift. 它面向 Java 开发人员, 但这对所有程序员都有帮助. 本课程的目标是为您提供这些语言的基础知识，以便您更轻松地开始创建 Android 应用程序.
Android 编程语言是软件开发人员的热门选择. 您可以找到各种有关使用 Java 进行 Android 编程的书籍和教程. 然而, 如果您对 Android 编程完全陌生, 需要花费一些努力来理解各种概念和语言. 在本文中, 我们将解释 Java 中 Android 编程的基础知识以及可用于创建应用程序的各种开发环境.
Android 应用程序由各种活动组成, 可以在屏幕页面上查看. 当您单击这些屏幕之一时, 您将转到下一个活动. 主要活动由 Java 类组成, 它们是 Activity 和 AppCompatActivity 的子类. 它是您的应用程序的入口点，并具有静态方法 main() 和 onCreate(). 使用这些类, 您将能够创建在任何 Android 设备上流畅运行的用户界面.
当您开始使用 Android 时, 你必须学习Java. 您可以通过介绍性书籍或免费的应用程序开发工具包获得 Java 的基本介绍. Java 是一种用于创建 Android 应用程序的流行编程语言, 但它有很多陷阱. Java 的主要问题是它需要完全不同的编程风格. 尽管 Java 是一个流行的选择, Python 作为学生的入门语言越来越受欢迎.
作为 Java 的替代方案, 许多开发人员正在转向 Kotlin. 与 Java 不同, Kotlin 与平台无关，可以快速学习. 它还可以更大程度地减少错误, 这使得 Kotlin 成为 Android 编程的绝佳选择. Soren Rauchle 在 3pc GmbH Neue Kommunikation 工作, 并拥有使用 Java 进行 Android 编程以及在移动应用程序中使用 Artliche Intelligence 的技能.
如果您需要您的应用程序快速运行, Java 是比 Python 更好的选择. Python不支持虚拟机, 但Java有广泛的优化功能. 这两种语言都提供库和 API 供 Android 程序员使用. 虽然两种语言都有各种优点, Python 更适合需要使用遗留系统的开发人员. 逐步改变系统也更容易. 尽管存在差异, 这两种语言对 Android 程序员都有很多好处.
作者还全面介绍了用Java进行Android编程. 它解释了专业应用程序开发的重要方面, 从数据存储到后台进程. 本书向读者展示了如何有效地使用Android Studio. 本书还介绍了如何使用Android SDK, 数据存储, 和互联网服务. 对于有抱负的 Java 开发人员来说是一本很好的指南, Android Java 编程是一个很好的资源. 在学习语言的同时, 您将对 Android 生态系统有更深入的了解.
如果您想为 Android 设备开发应用程序, 你应该了解 Android 版 Objective-C. Objective-C 源自 Smalltalk, 用于创建软件的语言. 它的语法与C非常相似, 但它实现了 Smalltalk 风格的消息传递. 当你使用 Objective-C 创建 Android 应用程序时, 您应该确保将实现和接口声明为单独的代码块. 您应该将接口放在头文件中，将实现放在代码文件中. 这两个文件与 C 代码文件非常相似, 因此您可能需要在开始之前阅读两者的文档.
使用 Objective-C 进行 Android 编程有几个优点. 与斯威夫特相比, 这门语言很容易学, 提供极致性能, 并被广泛推荐用于构建新平台. 它也比 Objective-C 更快, 但还不太成熟. 然而, 它仍然会收到未来的更新并随着时间的推移变得更好. 不考虑 Swift 的缺点, 开发人员可以从将其与 Objective-C 一起使用中受益.
而 Java 语言是 Android 最流行的编程语言, 在 Android 上使用 Objective-C 时需要记住一些事情. 例如, 您将可以访问更广泛的库和工具. Objective-C 也比 Java 更容易访问, 这样您就可以为 iOS 和 Android 编写应用程序. 如果您想使用 Java 来开发您的应用程序, 您需要了解其语法并使用可以在 iOS 设备上运行它的 IDE.
Kotlin 是一种用于 Android 开发的开源语言. 它发明于 2011 and was released in principal stable delivery in 2016. 在 2017, Google declared Kotlin as its best app-development language. But the decision is not final, as Google is in a legal battle with Oracle over Java APIs. Despite its many advantages, it is still inferior to Objective-C for Android programmierung. It has fewer features and is slower than Java.
As the default language of Apple’s iOS devices, Objective-C has a large library and is familiar to practically every iOS developer. Objective-C is a reliable language, and you don’t have to constantly update it, unlike many of the other programming languages on the market. 然而, the language is not very flexible, and you should keep this in mind when choosing the right language for your mobile development. 然而, if your idea is complicated enough, you should choose an alternative language for the project.
It is also very easy to learn, and it is not difficult to get started. You don’t have to know any code to get started, as you’ll find tutorials on Android development in Objective-C for Android. You can even download Objective-C for Android from the official Google Play Store. This will help you learn the language and make your application even more productive. You can start writing your own apps today!
If you’re a developer who is working on Android apps, you might have wondered if you should learn how to program in Swift or Kotlin. Both of these programming languages are open source and are becoming increasingly popular, but which one should you learn first? Learn more about both in this article. If you’re already familiar with Java, you can also move on to Swift. But if you’re looking for something new, consider learning Kotlin first.
The language is a great choice for building mobile apps. It’s free and open source and works on both Mac and iOS devices. It also allows you to contribute to the Swift Quellcode and download binaries for Linux and OS X. If you’re interested in learning how to code in Swift, it’s important to remember that the programming languages are quite similar. Swift is more complex than Objective-C, but it’s not impossible to learn.
Both Swift and Kotlin are statically typified programming languages, and they are widely used in iOS and Android apps. Kotlin has been replacing Java as the most popular language for Android app development. It is fully compatible with Java and is constantly being developed. But the differences between Kotlin and Swift are not great, and you should only use them if you’re already familiar with Java. You can also choose to learn Kotlin if you’re looking for an alternative to Swift or Java.
While you should learn Swift to code for Android, it would be best if you already know Java. The native programming environment of Android uses LLVM compilers, so your Swift code will be interpreted just like any other C/C++ code. 除此之外, you’ll also be able to reuse C/C++ development tools, such as the low-level debugger and profiling tools. You’ll want to know what these languages are because they’re both written for the same purpose: to develop Android apps!
Android developers can choose whichever programming language suits their needs. Swift is the most popular programming language for iOS, but it’s also an extremely powerful programming language for Android. The difference in programming languages, as well as the platform they run on, are important. iOS app development is more efficient for both platforms, but Swift is generally easier for programmers to learn. The advantages of both languages are well worth the learning curve. This article explains the differences between the two languages, and gives a good idea of which language is more suitable for your specific needs.
iOS apps are flexible, and can be tailored to meet your needs. Swift is an excellent choice for this kind of development. The authors walk you through the entire process step by step, providing practical examples and avoiding pitfalls along the way. You can also take advantage of iOS’s licensor terms and guidelines, and learn about the requirements of Apple’s strict app approval process. If you choose this path, you’ll be well on your way to making a successful app.
