如何从对话框导航到导航组件中的片段?

这是导航图. <导航xmlns:android ="http://schemas.android.com/apk/res/android"xmlns:app =" http://schemas.android.com/apk/res-autoxmlns:tools ="http://schemas.android.com/tools"android:id ="@@ id/home";app:startDestination =" @ + id/titleScreen"><片段android:id ="@@ id/titleScreen"android:name ="com.example.android.navigationadvancedsample.homescreen.Title"android:label =&"; @ string/title_home"工具:layout ="@ layout/fragment_title"<动作android:id =" @ + id/action_title_to_about"app:destination ="@ id/aboutScreen"/></fragment><对话android:id ="@@ id/aboutScreen"android:name =" com.example.android.navigationadvancedsample.homescreen.About"android:label =&"; @ string/title_about"工具:layout ="@ layout/fragment_about"<动作android:id =" @ + id/action_aboutScreen_to_register"app:destination =" @ id/register"/></dialog><片段android:id =" @ + id/register"android:name ="com.example.android.navigationadvancedsample.formscreen.Register"android:label ="fragment_leaderboard"工具:layout ="@ layout/fragment_leaderboard"；/></导航> 为什么会出现这种现象或如何解决?通过修复，我的意思是正常的对话框行为.假设我在片段 A 上方有一个对话框 D ，然后从 D 上的按钮移至片段 B strong>，屏幕上应显示 B .当我从 B 弹出时，它应该转到 A 上的 D 的上一阶段.解决方案感谢@musooff提交此错误 此问题已在导航2.1.0-alpha06和其他对话框不一致问题中得到解决，例如返回按钮，当对话框弹出.但是，如果可以，请更新到2.1.0-beta02或更高版本.I am trying to navigation from DialogFragment to Fragment in Navigation Component, but getting weird result.When I navigate from DialogFragment to Fragment, background fragment is changing to target fragment with current dialog on top of it, instead of just moving to target fragment.Here is the navigation graph.<navigation xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/home" app:startDestination="@+id/titleScreen"> <fragment android:id="@+id/titleScreen" android:name="com.example.android.navigationadvancedsample.homescreen.Title" android:label="@string/title_home" tools:layout="@layout/fragment_title"> <action android:id="@+id/action_title_to_about" app:destination="@id/aboutScreen"/> </fragment> <dialog android:id="@+id/aboutScreen" android:name="com.example.android.navigationadvancedsample.homescreen.About" android:label="@string/title_about" tools:layout="@layout/fragment_about"> <action android:id="@+id/action_aboutScreen_to_register" app:destination="@id/register" /> </dialog> <fragment android:id="@+id/register" android:name="com.example.android.navigationadvancedsample.formscreen.Register" android:label="fragment_leaderboard" tools:layout="@layout/fragment_leaderboard" /></navigation>Why I am getting this behavior or how to fix it?By fixing I mean normal dialog behavior. Say, I have a dialog D on top of a fragment A and move to a fragment B from a button on D, the screen should show B. And when I pop back from B, it should go to previous stage of D on top of A. 解决方案 Thanks @musooff for filing this bugThis problem was fixed on Navigation 2.1.0-alpha06, along with others dialog inconsistencies like back button when Dialog is popped.However, update to 2.1.0-beta02 or higher if you can. 这篇关于如何从对话框导航到导航组件中的片段?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
