java - CreateFromRessource ChipDrawable : The style on this component requires your app theme to be Theme.MaterialComponents

Question

With using AppCompat and using min sdk version 21, I try to use ChipDrawable to use in a list of email adresse in a TextEdit, and I create that ChipDrawable with :

ChipDrawable chip = ChipDrawable.createFromResource(getApplicationContext(), R.xml.email_chip);

using this xml :

<?xml version="1.0" encoding="utf-8"?>
<chip xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:chipBackgroundColor="?colorAccent"
    app:closeIconEnabled="true"
    app:closeIconTint="@android:color/white" />

My theme use Theme.MaterialComponents.DayNight.DarkActionBar (and I also tryed Theme.MaterialComponents.DayNight.DarkActionBar.Bridge)

But I always get this error :

The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).

I tryed everything I found on stackoverflow but it didn't helped much.

Here is my style

<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <style name="Theme.Mareu" parent="Theme.MaterialComponents.DayNight.DarkActionBar.Bridge">
        <!-- Primary brand color. -->
        <item name="colorPrimary">#4E92DF</item>
        <item name="colorPrimaryVariant">#3F7ABD</item>
        <item name="colorOnPrimary">@color/white</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/teal_200</item>
        <item name="colorSecondaryVariant">@color/teal_700</item>
        <item name="colorOnSecondary">@color/black</item>
        <!-- Status bar color. -->
        <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
        <!-- Customize your theme here. -->
    </style>
</resources>

Answer 1

The issue is here:

ChipDrawable chip = ChipDrawable.createFromResource(getApplicationContext(),

The ApplicationContext doesn't have your app theme.
You need to pass the Activity, not an Application Context.
