Question

当我试图运行我的程序时，我有下一个错误。我看了其他类似的问题，他们问他们的代码中是否有列表视图。问题是我的代码中没有列表视图或列表活动。

这是GitHub上的项目。

以下是错误日志：

Answer 1

您正在使用将BidListFragment extends ListFragment更改为BidListFragment extends Fragment它可以正常使用。并且您没有使用ListFragment的任何属性，因此您可以使用Fragment本身

检查this

为此，视图层次结构必须包含ListView对象 id“@android：id / list”（或列表，如果它在代码中）

您的内容必须具有ListView，其id属性为＆＃39; android.R.id.list＆＃39;错误
