ImageButton 在 1 次使用 Android 后停止工作

Question

所以聽我說，我使用一個按鈕打開一個活動，該活動生成一個項目，然后將其返回到原始片段並顯示在 recyclerview 中......但是一旦我嘗試添加第二個項目，ImageButton 就贏了'不要讓我再次訪問項目生成活動，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，它就可以正常工作，但是我無法按照自己的意願自定義它的外觀。 以下是一些圖像和代碼：

Answer 1

基本上我在 recyclerView 和 ImageButton 之間切換了位置，問題是當我向 recyclerView 添加一個項目時，它有點將回收器視圖放在按鈕的“前面”，這使我無法單擊 ImageButton。
