###### tags: `第12屆IT邦幫忙鐵人挑戰賽` `IThome` `Kotlin` `Android` `Mobile Development` # Day 03 | Kotlin 起手式: IDE 怎麼選? 在上一篇簡單介紹了 Kotlin 和 Java 的不同以及他的特色,那這篇就要延伸到基礎語法以及如何使用了! ## IDE 選擇 在 Kotlin 的開發上會有下列幾種 IDE 可以選擇,讀者可以選擇自己順手的 IDE 即可 ![](https://i.imgur.com/3D7GmRZ.png) ### 1. IntelliJ IDEA [IntelliJ IDEA](https://www.jetbrains.com/idea/) 是 Jetbrains 打造給 Java 、 Kotlin 和 Scala 開發者的 IDE,因為需要付費,所以我也沒有是用過,但據說是非常符合 Java 開發者尿性的工具,另外 IntelliJ IDEA 還有 Ktor (Kotlin 網頁開發框架)的 Plugin ,所以在上面能做到用 Koltin 開發 Web 前後端、 API 、 App 等等,可說非常之強大阿~ ### 2. Eclipse [Eclipse](https://www.eclipse.org/downloads/) 是開發 Java 的老牌 IDE ,相信很多人剛開始學 Java 都是從它開始的,在 Android Studio 出來之前, Android App 開發也是使用 Eclipse (我用它刻過一次 UI ,超級崩潰),目前 Eclipse 也有提供 Kotlin plugin 給開發者,具體導入流程在 [Kotlin 的官網](https://kotlinlang.org/docs/tutorials/getting-started-eclipse.html)上有介紹 ### 3. Android Studio [Android Studio](https://developer.android.com/studio) 是 Jetbrains 和 Goolge 合作開發,專門為寫 Android App 的開發者打造的 IDE ,在Android Studio 3.0 之前,開發者如果想用 Kotlin 必須手動處理, 但在 Android Studio 3.0 之後, Kotlin 已經變成內建支援的語言了,在新建專案時便可選擇此專案是否要支援 Kotlin 語法,之後開始寫 App 開發時變會再重新講解。 ### 4. Standalone Compiler 我不確定會有什麼樣的 Scenario 需要開發者用 Commnad line 開發 Kotlin ,所以這邊就提供[安裝 Kotlin 流程](https://kotlinlang.org/docs/tutorials/command-line.html)給有需要的讀者們 --- 上面介紹了一長串不同的 IDE,但如果只是要體驗 Kotlin ,學習基礎 Kotlin 用法,就不會希望有很煩雜、很久的安裝流程,因此除此之外我們還有一個比較快速可以體驗的選擇,就是採用 Online IDE ## Kotlin Playground [Kotlin Playground](https://play.kotlinlang.org/) 是我大 JetBrains 開發的專門給 Kotlin 的 sandbox ,用戶可以很快的得到一個可以開發 Kotlin 的環境,大多數 Kotlin 的語法他都支援,因此這也是我很常會使用的一個實驗工具,可以很快的透過他來印證我的猜想,而不需要在開一個 Project 或是重 Build Project ,節省很多時間。 如果在練習上想要體驗不同 Kotlin Version 帶來的不同, JetBrain 也很貼心的設計了 Run configuration 給開發者去做版本的切換。 另外他還提供了 Share code 的功能,可以分享 sandbox 給其他人,或是將 code 嵌入到網頁中,這在 Kotlin 的一些範例教學也會時常看到喔! ![](https://i.imgur.com/nQlXP4R.png) ## 結語 因為剛開始的範例都會是偏基礎語法,因此讀者們可以先從 Kotlin Playground 使用起,另外想裝 IDE 的讀者可以去 Koltin 官網上依照教學一步步建立,這邊就不在多寫文章去做教學了。 除此之外,因為 Kotlin 1.4 在近期 Release ,所以後面的教學都會以 Version 1.4 為主喔。 ## Reference * https://www.jetbrains.com/idea/ * https://play.kotlinlang.org/
