當我運行我的應用程序時，一切都運行完好，直到我選擇第三個選項卡組成我所做的listfragment，因此它顯示與數據和圖像的列表視圖，一旦選擇該應用程序只給出正常的消息不幸的是應用程序停止工作，logcat發送大量的紅色錯誤。當選中選項卡並出現錯誤時，Listfragment崩潰

，我在這個類改變了其使用是extends Fragment到extends ListFragment主要的事情我相信這是產生錯誤，雖然不知道怎麼辦？

這這裏的適配器可以使片段來回報每類認爲這是不允許它的值。

乾杯
UPDATE：
與ID /列表XML實現的列表視圖時新的錯誤發生的歷史。

問題是在你的xml..u需要給列表視圖的id作爲@android：id/list「 –
