IllegalArgumentException：无法从当前目的地 Destination 找到导航操作/目的地 [导航错误]

Question

我对导航图和导航组件不太熟悉，我正在尝试将数据从位于“PrivSectionFragment”中的回收器视图传递到“PrivSectionDetailFragment”。不幸的是，每当我运行该应用程序时，我都会在日志中收到此错误

\n

 java.lang.IllegalArgumentException: Navigation action/destination com.gazelle.wadifatk:id/action_privSectionFragment_to_privsDetailFragment cannot be found from the current destination Destination(com.gazelle.wadifatk:id/jobsFragment) label=\xd8\xa7\xd9\x84\xd9\x88\xd8\xb8\xd8\xa7\xd8\xa6\xd9\x81 class=com.gazelle.wadifatk.jobLists.jobsFragment\n    at androidx.navigation.NavController.navigate(NavController.java:940)\n    at androidx.navigation.NavController.navigate(NavController.java:877)\n    at androidx.navigation.NavController.navigate(NavController.java:863)\n    at androidx.navigation.NavController.navigate(NavController.java:1159)\n    at com.gazelle.wadifatk.jobLists.PrivListAdapter.onBindViewHolder$lambda-0(PrivListAdapter.kt:55)\n

\n

这就是它所指的地方// 它指的是我的回收器适配器

\n

PushDownAnim.setPushDownAnimTo(holder.card_view)\n        //.setScale(PushDownAnim.MODE_SCALE, 0.89f)\n        .setOnClickListener {\n            val sendData = PrivSectionFragmentDirections\n                .actionPrivSectionFragmentToPrivsDetailFragment(priv_list[position])\n            Navigation.findNavController(view).navigate(sendData)\n        }\n

\n

这是 my_nav.xml // 蓝色圆圈\n

\n

请记住，我能够通过使用相同的动作将数据从“LatestNewsFragment”传递到“NewsDetailsFragment”，但我不知道为什么它接受了这些片段之间传递的数据，但没有“不接受从“PrivSectionFragment”到“PrivSectionDetailFragment”。

\n

这是片段的代码

这是 jobsFragment() 的屏幕截图

您只需JobsFragment在导航图中添加，并在此片段中添加操作PrivsDetailFragment。

\n

<fragment\n    android:id="@+id/jobsFragment"\n    android:name="com.gazelle.wadifatk.jobLists.jobsFragment"\n    android:label="\xd8\xa7\xd9\x84\xd9\x88\xd8\xb8\xd8\xa7\xd8\xa6\xd9\x81"\n    tools:layout="@layout/fragment_jobs" >\n    <action\n        android:id="@+id/action_jobsFragment_to_govSectionFragment"\n        app:destination="@id/govSectionFragment" />\n    <action\n        android:id="@+id/action_jobsFragment_to_latestNewsFragment"\n        app:destination="@id/latestNewsFragment" />\n    <action\n        android:id="@+id/action_jobsFragment_to_privsDetailFragment"\n        app:destination="@id/privsDetailFragment"\n        app:enterAnim="@anim/nav_default_enter_anim"\n        app:exitAnim="@anim/nav_default_exit_anim" />\n</fragment>\n

\n

然后在您的适配器中，使用以下操作：

\n

PushDownAnim.setPushDownAnimTo(holder.card_view)\n        //.setScale(PushDownAnim.MODE_SCALE, 0.89f)\n        .setOnClickListener {\n            val sendData = JobFragmentDirections.actionJobFragmentToPrivsDetailFragment(priv_list[position])\n            Navigation.findNavController(view).navigate(sendData)\n        }\n

\n

您可以privSectionFragment从导航图中删除。
