下面是我的適配器類和視圖代碼，其中我爲每行顯示了2個按鈕。我爲每個按鈕設置了2個diff偵聽器。特定行上的Recyclerview按鈕 - 如何在onclicklistener之前捕獲行ID？
剛接觸android時，我不確定如何獲取getbarCode()（某種行ID）的特定行按鈕被點擊？ （這個我想用來設置我打電話給我的web服務的條形碼b4）。目前我已在代碼中硬編碼，我想從我的書籍getbarCode()中獲得它。
有什麼建議嗎？

謝謝，讓我試試看。 – Dep
你能告訴我 - 如何「獲取訪問（或路徑事件）列表書籍;在你的適配器」？我無法找到。 –

明白了。非常感謝！！ – Dep
