如何修复此错误？它在哪里被泄露？是什么造成的？

Answer 1

当活动结束并进入后台时，您正在尝试显示对话框。内部活动检查活动是否正在完成。

if(isFinishing()) return;
final Dialog dialog = new Dialog(getActivity());
dialog.show();

在片段中你可以写：

if(getActivity() != null && !getActivity().isFinishing()) {
    final Dialog dialog = new Dialog(getActivity());
    dialog.show();   
}
