Ich habe eine ListView, die einen Adapter verwendet, der ein String-Array als Argument erhält. Wenn ich mir die Listenansicht anschaue, wird 1 Element angezeigt, dann wird dahinter viel Leerzeichen angezeigt, gefolgt vom nächsten Element, wenn ich nach unten blättere. Was könnte das Problem sein? HierAndroid ListView mit einem Element pro Seite
