プログラムに 2 つのリスト ビューがあるのは奇妙です。最初のリストビューは Android:id="@android:id/list" を設定し、2番目のリストビューは私のIDを Android:id="@+id/list1" に設定しました。
これは正しい方法ですか？2 番目のリストビュー ID を android:id="@+id/list1" に設定すると実行できないため、ID の障害であるか、コードに問題があるためではないかと考えていました。
actionbarsherlock で jeremy ライブラリを使用しています。私は、彼のメニューを取得するために listView findviewbyid(list) を使用して彼を見つけられないジェレミーの例に従っているだけです。ID を変更した後、アプリケーションがクラッシュしました。ありがとう
