リストビューのチェックボックスをチェックボックスでチェックし、リストビューを別のタブに変更した後、前のタブに戻ると、チェック....私はどのように私はタブを変更するとチェックボックスをチェックし、前のタブに復帰した後も維持することができますか？前もって感謝します！共有設定が保存されないチェックボックスが選択されていない
これは
アダプター....私のコードです：

、状態がに変更された場合は、 '確認' == false'を..しかし、これは 'editor.putBoolean（" holder.chkBox "+ finalHolder.planetName.getText（）。toString（）、false）; 'これは1つの可能なエラーである可能性があります... – user0815
あなたの' 'putBoolean'の後に' editor'を追加します。異なる「エディタ」を「コミット」します。 –
私はedit.putBoolean（ "holder.chkBox" + finalHolder.planetName.getText（）。toString（）、false）と書く。しかし、動作しません.. – markella
