Ajout d'un bouton d'action flottant au blocage de la vue du recycleur: le style de ce composant nécessite que le thème de votre application soit Theme.AppCompat

J'essaie d'ajouter un bouton d'action flottant unique à chaque élément dans une vue de grille de recycleur. J'ai essayé de changer le thème en MaterialComponent mais cela n'a pas fonctionné. L'erreur m'indique que le crash se produit pendant l'inflation et que mon thème n'est pas AppCompat même s'il est dans les styles. Je pense que je devrais peut-être ajouter quelque chose dans le XML, mais je ne suis pas sûr. Quelqu'un sait-il comment résoudre ce problème?

Qu'est-ce que mContext? Que transmettez-vous cette valeur?

@GabrieleMariotti C'est le contexte de MainActivity qui est passé dans l'adaptateur, je pense.

Pouvez-vous publier le code où vous instanciez l'adaptateur et passez le contexte?

@GabrieleMariotti vient d'être ajouté et le XML pour MainActivity et Gradle

Vérifiez simplement la réponse ci-dessous. Vous devez transmettre l ' Activité , pas un Contexte d'application. Faites juste attention car les composants matériels v1.1.0 nécessitent un thème Theme.MaterialComponents .

L'erreur indique que votre application doit avoir le thème. Pour ce faire, dans votre fichier manifeste, dans votre balise d'application, ajoutez votre thème: 

implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.core:core-ktx:1.1.0'
implementation 'com.google.android.material:material:1.1.0'

Et dans votre application build.gradle ajoutez les dépendances suivantes 

<application 
          your application configurations
          android:theme="@style/AppTheme">

viens de terminer la réponse, fais-moi savoir si ça te fait l'affaire

Même erreur, malheureusement. Cependant, je n'avais pas l'implémentation core: core auparavant. Ajouté maintenant.

Avez-vous inclus le package de conception de matériaux dans le fichier build.gradle de votre application? 

dependencies {
    // ...
    implementation 'com.google.android.material:material:1.1.0'
    // ...
}

mAdapter = new AnimalsAdapter(this, arrayList);

Il y a un problème avec le contexte utilisé pour instancier l ' adaptateur . Vous devez transmettre l ' Activity , pas un ApplicationContext .
Le contexte de l'application n'a pas le thème de votre application.

Dans votre activité, changez 

mContext = getApplicationContext();
mAdapter = new AnimalsAdapter(mContext, arrayList);

en 

Caused by: java.lang.IllegalArgumentException: 
The style on this component requires your app theme to be Theme.AppCompat (or a descendant).

Faites également attention car avec les composants matériels 1.1.0 votre thème d'application doit hériter d'un Thème des composants matériels .
