问题描述
因此，我创建了一个DialogFragment，它通过此技术
So I've created a DialogFragment that is shown as a dialog via this technique
现在，它已启动，并且在此弹出窗口中与用户交互时，我想在此对话框的另一个片段中滑动.我正在尝试通过FragmentTransaction.add()来执行此操作，在此我给它提供此布局中容器之一的ID.此时，我得到:
Now that it's launched and upon a user interaction within this popup I want to slide in another fragment to this dialog. I'm trying to do this via FragmentTransaction.add() where I give it the id of one of the containers in this layout. At this point I get:
java.lang.IllegalArgumentException: No view found for id 0x7f09013f for fragment <fragmentClassThatIWasPushingIn>
作为一个快速测试，我尝试将其推入容器ID中，而不是在对话框中，而是在主要支持活动中，并且效果很好.
As a quick test, I tried to push it onto a container id not in the dialog but within the main backing activity and that worked just fine.
关于DialogFragments及其容器ID是否存在不允许FragmentTransactions的内容?
Is there something about DialogFragments and its container ids that does not allow for FragmentTransactions?
作为权宜之计，我告诉我的交易隐藏当前的DialogFragment并显示此新片段，但是动画/显示有些刺耳，所以我真的很想解决此问题.
As a stopgap I've told my transaction to hide the current DialogFragment and show this new fragment, but the animation/display is a little jarring so I'd really like to sort this issue out.
谢谢
推荐答案
当 DialogFragment 显示为 Dialog 时，它实际上不是真正的 Fragment 在容器视图中.它是一个无容器的 Fragment ，基本上是 Dialog 的包装.
When a DialogFragment is shown as a Dialog it is not actually a real Fragment in a container view. It is a container-less Fragment which is basically a wrapper of a Dialog.
所以不，您不能在 FragmentDialog 内显示 Fragment .如果您确实想执行此操作，我认为最好的方法是创建一个样式为 Dialog 的新 Activity ，然后您也可以添加 Fragments
So no, you can not show a Fragment inside a FragmentDialog. If you really want to do this I think the best way would to create a new Activity styled as a Dialog which you can then add Fragments too.
