I am new to navigation graphs and navigation components in general and I am trying to pass data from the recycler view that's located in 'PrivSectionFragment' to 'PrivSectionDetailFragment'. Unfortunately, whenever I run the app I receive this error in my log

 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 com.gazelle.wadifatk.jobLists.PrivListAdapter.onBindViewHolder$lambda-0(PrivListAdapter.kt:55)

This is where it refers // it refers to my recycler adapter

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

This is my_nav.xml // the blue circle

keep in mind that I was able to pass the data from 'LatestNewsFragment' to 'NewsDetailsFragment' just by using the same moves and I don't know why it accepted the data passing between those fragments and didn't accept it from 'PrivSectionFragment' to 'PrivSectionDetailFragment'.

here is the code of the fragments

Here is a screen shot of the jobsFragment()

CodePudding user response：

You need to add only JobsFragment in your nav graph and add action in this fragment for PrivsDetailFragment.

<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>

And then in you adapter, using this action:

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

You can remove privSectionFragment from the nav graph.
