how fix Error inflating class android.support.design.widget.NavigationView

Question

I have problem and I can't find the solution ! I use in XML :

<?xml version="1.0" encoding="utf-8"?>

    <androidx.drawerlayout.widget.DrawerLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:id="@+id/activity_main"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      tools:context="com.example.libraryproject.MainActivity"
      android:background="@android:color/holo_green_dark">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">


        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Main"
            android:textSize="50dp"
            android:id="@+id/textView"
            android:layout_marginTop="200dp"
            android:layout_marginLeft="130dp"/>


    </RelativeLayout>

    <android.support.design.widget.NavigationView ------! #32
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        app:menu="@menu/navigation_menu"
        android:layout_gravity="start"
        app:headerLayout="@layout/navigation_header"
        android:id="@+id/nv">
    </android.support.design.widget.NavigationView>

</androidx.drawerlayout.widget.DrawerLayout>

And the error show is : android.view.InflateException: Binary XML file line #32: Binary XML file line #32: Error inflating class android.support.design.widget.NavigationView

in app :

Answer 1

In your build.gradle there are some errors:

• the support libraries 29.0.2 and 29.1.1 don't exist
• you are using androidx and support libraries together and you can't do it.

Then, since you are using the androidx component <androidx.drawerlayout.widget.DrawerLayout you have to use the

<com.google.android.material.navigation.NavigationView
 ...>

instead of android.support.design.widget.NavigationView.

Finally check your App theme. You have to use a Material Component Theme.
