Question

当我在不使用活动的情况下将片段放入dialogfragment时，我收到IllegalStateException。我的设计不是使用活动。在这方面有谁能帮助我？

代码段：

popUpFragment = this;
popUpFragment.dismissPopUp += DismissPopUpDialog;
dialog = new PopUpDialogFragment(popUpFragment, this.GetString(Resource.String.signin_btn_title), HeaderButton.Close, this.Resources.GetDimension(Resource.Dimension.Tablet_Popup_Width), this.Resources.GetDimension(Resource.Dimension.Tablet_Signin_Height), true);
dialog.Show(this.Activity.SupportFragmentManager, "test dialog");

以上代码已在片段的构造函数中使用。我得到的例外是：

Answer 1

Fragment和DialogFragment必须使用Activity实现让活动将信息传递给其他片段，或者您可以使用AlertDialog.Builder。看看这里：Dialogs

放置在dialogfragment内部时出现片段IllegalStateException
