私は、2つのチェックボックス（より正確には5個）を表示する警告ダイアログを持っています。チェックボックスフィルタ5は、マップ上に表示されるマーカーのリスト、時間間隔でグループ化されたマーカーです。私はonSaveInstanceStateにコードを書くべきであることがわからないという事実を除いて、すべてが機能するように管理していますので、チェックボックスの値は画面の回転後も保持されます。ここでは、私はそれが質問に関連していると思うコードの部分です。助けをあらかじめありがとう！onSaveInstanceStateでチェックボックス状態を保存する方法

お手伝いすれば回答を受け入れてください。 – notsopopularguy
私は以前このアイデアを試してみましたが、残念ながらそれは機能しません。私はこのコードを追加していますが、同じことが回転すると、チェックボックスがリセットされ、前回のチェックを保持していないだけでなく、画面の回転後に動作していない（何もフィルタリングしていません）... –
onCreateメソッドのバンドルから読み取ってチェックボックスの値を取得しますか？ – notsopopularguy
