私はこのエラーを解決する方法を、教えてください？
このリンクを参照してくださいhttp://stackoverflow.com/questions/26515058/t彼の活動は、既に持っているアクションバーの窓付きの装飾 –
あなたがエラーを見ると、それはある時点で言うことができます： "原因：java.lang.IllegalStateException：これはアクティビティにはすでにウィンドウデコレーションによってアクションバーが提供されています。あなたのテーマでWindow.FEATURE_SUPPORT_ACTION_BARを要求せず、windowActionBarをfalseに設定して、代わりにツールバーを使用するようにしてください」上記のコメントによってリンクされた質問によって対処されているようだ。 – Acapulco
