Android.Views.InflateException Binary XML file line #1 in layout/toolbar: Error inflating class androidx.appcompat.widget.Toolbar

Question

Android.Views.InflateException Binary XML file line #1 in layout/toolbar: Error inflating class androidx.appcompat.widget.Toolbar

pierre-louis deschamps 146

In a xamarin.forms android project, MainActivity.cs contains:

  [Activity (Label = "Almicantarat", Theme = "@style/MainTheme",  
  Icon = "@drawable/almicantarat_launcher",   
  MainLauncher = true,  
  ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]  
  public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity  
  {

I need to remove:

Theme = "@STYLE /MainTheme",

in order to use a custom theme and a toolbar.

But then I met the following exception:

Android.Views.InflateException
Message=Binary XML file line #1 in almicantarat.almicantarat:layout/toolbar: Binary XML file line #1 in almicantarat.almicantarat:layout/toolbar: Error inflating class androidx.appcompat.widget.Toolbar

This is styles.xml:

<?xml version="1.0" encoding="utf-8" ?>  
<resources>  
  <style name="AlmicantaratTheme" parent="@android:Theme.Material">  
      <item name="android:windowNoTitle">true</item>  
      <item name="android:windowActionBar">false</item>  
      <item name="android:colorPrimary">#15014E</item>  
      <item name="android:colorPrimaryDark">#15014E</item>  
      <item name="android:navigationBarColor">#15014E</item>  
      <item name="android:statusBarColor">#15014E</item>  
      <item name="android:colorAccent">#FF4081</item>  
      <item name="android:windowActionModeOverlay">true</item>  
  </style>  
</resources>

This is Toolbar.axml:

<androidx.appcompat.widget.Toolbar  
    xmlns:android="http://schemas.android.com/apk/res/android"  
    xmlns:app="http://schemas.android.com/apk/res-auto"  
    android:id="@+id/toolbar"  
    android:layout_width="match_parent"  
    android:layout_height="?attr/actionBarSize"  
    android:minHeight="?attr/actionBarSize"  
    android:background="?attr/colorPrimary"  
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"  
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"  
    app:layout_scrollFlags="scroll|enterAlways" />

How can I solve that?

hint: this is an long time running project started in 2014. It migrated successfully to AndroidX.
It targets SDK 29 and requires minimum SDK 21.

using VS2019
Xamarin.Forms v5.0.0.2125

Hello pierrelouisdeschamps-1678,

Welcome to our Microsoft Q&A platform!

Error inflating class androidx.appcompat.widget.Toolbar

I tested the code and reproduced the issue on my side. This is because @android:Theme.Material theme is not applicable in AndroidX. Please using Theme.AppCompat.* instead. Such as:

   <style name="AlmicantaratTheme" parent="Theme.AppCompat.NoActionBar">  
     <item name="android:windowNoTitle">true</item>  
     <item name="android:windowActionBar">false</item>  
     <item name="android:colorPrimary">#15014E</item>  
     <item name="android:colorPrimaryDark">#15014E</item>  
     <item name="android:navigationBarColor">#15014E</item>  
     <item name="android:statusBarColor">#15014E</item>  
     <item name="android:colorAccent">#FF4081</item>  
     <item name="android:windowActionModeOverlay">true</item>  
   </style>

Pra mim, era só definir o tema para a outra tela

Done!
I got the following build error:
resource android:style/Theme.AppCompat.NoActionBar not found.

because I wrote:
<style name="AlmicantaratTheme" parent="@Krak ruiz :Theme.AppCompat.NoActionBar">

instead of:
<style name="AlmicantaratTheme" parent="Theme.AppCompat.NoActionBar">

Now it compiles!

Thanks
