Hands-on 2 | 3 | ## 題材 4 | 5 | GitHubのリポジトリをキーワード検索するアプリを作成します。 6 | 7 | ![rocket](https://raw.github.com/ntaro/kotlin-android-hands-on/master/art/capture.gif) 8 | 9 | ## 事前準備とスタート 10 | 11 | ハンズオンは[masterブランチ](https://github.com/ntaro/kotlin-android-hands-on)から始めます。 12 | 13 | このブランチは、コードや各種設定が記述済みです。 14 | ハンズオン開始までに **ビルド** と **実行** をしておいてください。 15 | 16 | コードは未完成で、ハンズオンの中で完成させていきます。 17 | 18 | ## 完成形 19 | 20 | [completedブランチ](https://github.com/ntaro/kotlin-android-hands-on/tree/completed)は、完成形です。 21 | 22 | ## ハンズオン課題 23 | 24 | ### `Repository`クラスの定義 25 | 26 | GitHub上に存在するリポジトリを表現するクラスを定義しましょう。 27 | 28 | プロパティ名|型|説明 29 | ---|---|--- 30 | `id`|`Long`|ID 31 | `fullName`|`String`|フルネーム＝「ユーザ名/リポジトリ名」 32 | `htmlUrl`|`String`|詳細URL 33 | `stargazersCount`|`Int`|スター数 34 | `owner`|`User`|リポジトリの所有者。Userクラスは定義済み 35 | `description`|`String?`|リポジトリの説明 36 | `language`|`String?`|言語 37 | 38 | ### ダミーデータのリスト表示 39 | 40 | ### インテント生成関数 + リポジトリ詳細画面 41 | 42 | ### Retrofitを使ってAPIアクセス 43 | 44 | ### async/awaitの体験 45 | 46 | ### スター付けた人のリスト表示機能を作る --------------------------------------------------------------------------------
