您好我正在製作一個字典應用程序，我希望當我從一個列表視圖中打開一個單詞，然後在單詞頁面（word.class）（這裏的單詞含義解釋） ，我想將這個單詞添加到listview形狀的favorite.class活動中，稍後我可以從列表視圖中檢索該單詞。通過sharedpreferences保存在列表視圖中的.class名稱
我想在一個java類中點擊最喜歡的按鈕，並在favorite.class的anathor活動中保存該單詞（字符串，它是該單詞的類名稱）。最喜歡的按鈕實際上是在操作欄上可見的菜單項。請解釋我所有的代碼和方式，我該如何做到這一點。請給一些代碼，以實現它。

您需要對java進行自己的研究。試着弄清楚自己，然後在這裏問一個具體的問題。 – cbrulak
你使用數據庫？你可以發佈一些代碼嗎？ –
不，我不使用數據庫...我希望它通過sharedpreferences存儲 – user2592807
