Android Multiple Nested DialogFragment

概述我有一个场景,我显示一个DialogFragment(使用getSupportFragmentManager()),显示一个值列表和一个“添加”按钮.如果用户单击添加按钮,我会显示另一个DialogFragment(使用由EditText和Button组成的getChildFragmentManager().当用户点击新Button时,如果值通过验证,我将其添加到列表中.如果不是通过验证,我显示另 我有一个场景,我显示一个DialogFragment(使用getSupportFragmentManager()),显示一个值列表和一个“添加”按钮.如果用户单击添加按钮,我会显示另一个DialogFragment(使用由EditText和button组成的getChildFragmentManager().当用户点击新button时,如果值通过验证,我将其添加到列表中.如果不是通过验证,我显示另一个显示错误消息的DialogFragment和一个“确定”按钮.我希望当按下“确定”按钮时,用户仍然会看到带有EditText和button的DialogFragment,这样他们就可以查看错误值并可能更改它.但是,当在错误消息DialogFragment中按下“确定”按钮时,对话框将被关闭,并且仅显示原始DialogFragment(具有值列表的那个).

在第三个DialogFragment被解散后,我如何保持第二个DialogFragment仍然显示？

编辑：这是一些代码片段：

解决方法 我想问题是你使用标准的show方法来显示对话框.根据AndroID的消息来源,这个方法不会向backstack添加片段,所以最顶层的对话框被解雇,中间也被解雇了.

您应该在调用show之前自己开始trasaction并将事务添加到backstack(调用addToBackStack).一个例子显示在DialogFragment documentation page上.
