I'm receiving Caused by: android.view.InflateException: Binary XML file line #32: Error inflati

Time:02-17

So I was trying to get my fragments with navigation component to work, but for some reason I'm getting that exception. I already searched for some solutions but didnt mine.Don't mind some spanish variables. I'm receiving the exception:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.iesnervion.pmdmo_prac2eva/com.iesnervion.pmdmo_prac2eva.view.MainActivity}: android.view.InflateException: Binary XML file line #32: Binary XML file line #32: Error inflating class androidx.fragment.app.FragmentContainerView

and it says that its caused by:

Caused by: android.view.InflateException: Binary XML file line #32: Binary XML file line #32: Error inflating class androidx.fragment.app.FragmentContainerView

My Fragment XML:

And this is the activity_main.xml (where I'm getting the error):

    app:defaultNavHost="true"
    app:navGraph="@navigation/nav_graph"
    />

And I don't know if u need this, but this is my nav_graph.xml

<navigation xmlns:android="http://schemas.android.com/apk/res/android"

    android:label="fragment_tienda"
    tools:layout="@layout/fragment_tienda" >
    <action
        android:id="@ id/action_tiendaFragment_to_detallesFragment"
        app:destination="@id/detallesFragment" />
</fragment>
<fragment

    android:name="com.iesnervion.pmdmo_prac2eva.fragments.DetallesFragment"
    android:label="fragment_detalles"
    tools:layout="@layout/fragment_detalles" />

Thanks for trying to help and if u need some other files in order to find a fix, just comment it

EDIT 2: I have 2 Fragments in my Activity, here you can see the design view: Navigation Graph Design View

And here is my MainActivity code:

class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

}

}

CodePudding user response:

onCreate() is too early to access binding that you are only setting up later in onCreateView().

You can e.g. move the binding.svProductos.setOnQueryTextListener(this) to onViewCreated().
