IllegalArgumentException：无法从当前目的地目的地找到导航操作/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

 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=الوظائف class=com.gazelle.wadifatk.jobLists.jobsFragment
    at androidx.navigation.NavController.navigate(NavController.java:940)
    at androidx.navigation.NavController.navigate(NavController.java:877)
    at androidx.navigation.NavController.navigate(NavController.java:863)
    at androidx.navigation.NavController.navigate(NavController.java:1159)
    at com.gazelle.wadifatk.jobLists.PrivListAdapter.onBindViewHolder$lambda-0(PrivListAdapter.kt:55)

这就是它所指的地方 // 它指的是我的回收器适配器

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

这是 my_nav.xml // 蓝色圆圈

请记住，我能够将数据从“LatestNewsFragment”传递到“NewsDetailsFragment” 只是通过使用相同的动作，我不知道为什么它接受这些片段之间传递的数据，而不接受从“PrivSectionFragment”到“PrivSectionDetailFragment”的数据。

这是片段的代码

这是 jobsFragment() 的屏幕截图

Answer 1

您只需在导航图中添加

JobsFragment

并在此片段中添加

PrivsDetailFragment

的操作。

<fragment
    android:id="@+id/jobsFragment"
    android:name="com.gazelle.wadifatk.jobLists.jobsFragment"
    android:label="الوظائف"
    tools:layout="@layout/fragment_jobs" >
    <action
        android:id="@+id/action_jobsFragment_to_govSectionFragment"
        app:destination="@id/govSectionFragment" />
    <action
        android:id="@+id/action_jobsFragment_to_latestNewsFragment"
        app:destination="@id/latestNewsFragment" />
    <action
        android:id="@+id/action_jobsFragment_to_privsDetailFragment"
        app:destination="@id/privsDetailFragment"
        app:enterAnim="@anim/nav_default_enter_anim"
        app:exitAnim="@anim/nav_default_exit_anim" />
</fragment>

然后在您的适配器中，使用以下操作：

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

您可以从导航图中删除

privSectionFragment

。

Answer 2

验证您的目的地是否需要参数，如果是真的，您可以添加到您的操作中

    PushDownAnim.setPushDownAnimTo(holder.card_view)
        //.setScale(PushDownAnim.MODE_SCALE, 0.89f)
        .setOnClickListener {
            val sendData = PrivSectionFragmentDirections

    sendData.setNameExtra(valueExtra)
                .actionPrivSectionFragmentToPrivsDetailFragment(priv_list[position])
            Navigation.findNavController(view).navigate(sendData)
        }

Answer 3

就我而言，我只是使用了错误的方向

findNavController().navigate(XFragmentDirections.toSomething)
