私はこの問題のさまざまな解決策を検索して実装しようとしましたが、この問題は何も解決していません。私はカスタムリストビュークラスを持っていて、私の主なアクティビティから呼び出されたときには、すべてが期待どおりに動作します。アイテムをクリックすると、次のアクティビティに移動します。しかし、私が新しいアクティビティでOnItemClickListenerの同じコードを呼び出すと、クリックに反応しません。私が困惑しているので、これの助けがあれば素晴らしいだろう。ListViewのOnItemClickListenerがクリックを識別しない
OCForumsAppActivityが主なアクティビティで、BothActivityは私のonItemClickListenerが動作しない場所です。
