私の展開可能リストビューでは、それぞれの子ビューにEditTextがあり、各テキスト更新時にモデルを更新する必要があるため、各EditTextにテキストウォッチャーを追加しようとしました。しかし、TextWatchersで使用すると、私のモデルはグループ&の子の位置に間違った値で入力されます。拡張可能リストビューで不必要な変更を引き起こすテキストウォッチャー
これは私のアダプターコード

注意と私のコンソール出力です：どのEditTextのデータもUIから変更していません。
TextWatchersを実装する方法が間違っているのですか、またはアダプタに問題がありますか？ TextWatcherを対応するグループ&の子の位置についてのみ更新することは明らかですが、それらは混同しています。
もう1つの観測では、私はconvertViewが 'getChildView'内のすべてのchildViewsのビューを返すと思います。 TextChangedListenerをconvertviewで表示するように設定しているので、問題を引き起こす可能性がありますか？
