遵循這一更有效的方式。
- 使用Map對象來存儲單個用戶數據。
- 將這些地圖對象添加到列表中。
- 使用自定義適配器顯示在ListView中。
- 無論何時用戶點擊特定列表項目，都意圖傳遞其位置。
- 從Bundle獲取位置並從List的映射中檢索特定的用戶數據。
- 顯示用戶的所有數據。
如果你想要一個代碼片段發送給我的用戶數據字段，我可以給你發送代碼片段。
這裏是代碼。

我不清楚這個問題...你可以請指定更清楚。您正在數組的列表視圖中顯示數據。當點擊每個項目時，你想要執行什麼......？ – Noby
我試圖做到這一點 - 當我從listView中選擇一個名字時，我希望它打開一個活動Bajzelj。然後根據我選擇的名字，我想填寫個人日期（每個人有不同的數據）。對於活動Bajzelj，我只想使用一個具有空TextViews和ImageView的XML。 – user925185
好吧，我明白你的要求。你在哪裏得到問題..在準備XML文件或獲取特定的數據。 – Noby
