こんにちは私は4つのタブで構成されたTabBarアプリケーションを開発しています。アプリケーションが開かれるたびに、最初のタブが選択されます。最初のタブでは、HTML5のコンテンツ（ラベルとテキストボックス）で構成されるWebViewをロードしています。テキストボックスにデータを入力して別のWebViewにナビゲートすると、このWebViewではスピンナー、つまりHTMLスピナーを使用しています。私は、次のExceptionを取得していますそのスピナーをクリックしたときにでも：

代わりsetcontentviewのレイアウトを膨らませる試みを使用している場合例外。 – user1195614
私はこの例外のための他の解決策を考えることができませんでした。すべてのfindViewById（）をviewToLoad.findViewById（）に変換してください。 – EedAndroid
はい私はすべてのfindViewById（）をviewToLoad.findViewById（）に変換しました。私はreplaceContentView（）メソッドを使用しましたが、このメソッドにはsetContentView（）も含まれています。私はこれで何かを変更する必要があるかどうか。 – user1195614
