所以請聽我說完，我使用一個按鈕打開一個活動，該活動生成一個專案，然后該專案將回傳到原始片段并顯示在 recyclerview 中......但是一旦我嘗試添加第二個專案，ImageButton 就贏了'不要讓我再次訪問專案生成活動，幾乎就像 ImageButton 已停用（我嘗試使用 setEnabled 和 setClickable 但它不會修復它），只要我使用 Button 而不是 ImageButton，它就可以正常作業，但是我無法按照自己的意愿自定義它的外觀。以下是一些影像和代碼：

uj5u.com熱心網友回復：
基本上我在 recyclerView 和 ImageButton 之間切換了位置，問題是當我向 recyclerView 添加一個專案時，它有點將回收器視圖放在按鈕的“前面”，這使我無法單擊 ImageButton。
正確代碼：
