私はいくつかのTextViewsと画像でExpandleListviewを持っています。 clikedの後、私はshowTextViewを子として使い、GroupViewの別のTextViewを非表示にします。残念ながら、リストは正しく表示されていますが、OnGroupClickListenerを設定してデバッグしようとすると、アイテムがクリックされても展開されません。そのブレークポイントはトリガーしません。Expandable ListViewは展開されません

EDIT：解決しよう：グループ項目でiはクリッカブル要素（ボタン）を有します。それはunfocusする必要があります（android：focusable = "false" in XML）
