我需要在我的viewHolder對象中設置標籤的幫助。我有一個比屏幕更長的列表（在電話上），我需要爲每個視圖設置不同的標籤。正如你可以在我的預覽應用程序（下面的鏈接）中看到的外部片段中的第一項和最後一項綁定在一起。我不'那樣想，我希望每一個觀點都是獨一無二的。我怎樣才能做到這一點。指定唯一標籤列表中的項目列表

我建議你學習getView的工作原理。意見將得到回收。而且你不應該使「每個視圖都是唯一的」 – 2014-09-10 16:16:00
我的列表不是一個動態列表，它是由string.xml文件中的字符串數組生成的預設列表。我希望我的所有觀點都保留 其onClickListeners和onCheckChangedListeners – AbsoluteHeero 2014-09-10 16:34:09
請解釋您試圖爲每個視圖設置不同標記的位置。我所看到的是，您將視圖持有者設置爲視圖標記。他們在哪個方面有所不同？什麼'保持點擊聽衆等'這樣做呢？當然還有更多的物品可以放在屏幕上。而您的Google文檔在我的平板電腦上無法讀取，因此我不知道那裏出了什麼問題。 – greenapps 2014-09-10 20:00:37
