DnD in Compose @punchdrunker 2025/4/4
自己紹介 - 2010〜 Android / iOS Dev - Director of
DroidKaigi Association - MNG - Tamagotchi Connect
ComposeでもDnD(ドラッグアンドドロップ)できる? - Jetpack Compose 1.6からDnDサポート追加 - 具体的には dragAndDropSource と dragAndDropTarget
を使う - Viewベースと同じく ClipData でデータを渡せる
最小限の実装の流れ 構成 - Modifier.dragAndDropSource → ドラッグしたいもの - ClipDataで中身を渡す - Modifier.dragAndDropTarget
→ ドロップ先 - DragAndDropEventでイベント受け取り 📦 データの受け渡しは ClipData.newPlainText("label", "value") みたいな感じ
example: dragAndDropSource
example: dragAndDropTarget 1/2
example: dragAndDropTarget 2/2 onDropだけ 実装必須
example: DragAndDropEvent - DragAndDropEvent - mimeType - DragEvent - Offset
- ClipData - …(たくさん)
まとめ まとめ: - ComposeでもDnDができるようになった - Modifierベースで導入も簡単 - ClipDataとDragAndDropEventの理解がポイント - 外部アプリからのDnD対応もできそうなのでやってみたい
- ファイルDnDなども試す予定!
