Impossible d'appeler l'annulé Android.view.View.setElevation (float) sur un objet null dans lapism/SearchView

J'utilise la bibliothèque lapism/SearchView ( https://github.com/lapism/SearchView ) dans mon projet. Mais je reçois une exception d’exécution seulement sur Android 5.0:

S'il vous plaît quelqu'un a une idée comment résoudre ce problème?

Pour résoudre ce problème, vous devez mettre à jour votre fichier XML qui contient SearchView et AppBarLayout. Ajoutez Android:stateListAnimator="@null" à votre AppBarLayout comme indiqué ci-dessous.

 <Android.support.design.widget.AppBarLayout
        Android:layout_width="match_parent"
        Android:layout_height="wrap_content"
        Android:stateListAnimator="@null">

Il indique que Android:stateListAnimator="@null" attribut stateListAnimator est uniquement utilisé dans l'API de niveau 21. Mais j'ai vérifié le code source de la bibliothèque et il se bloque dans la classe SearchBehavior lorsqu'il tente de définir mAppBarLayout.setStateListAnimator(null);

MODIFIER

Comme mentionné dans les commentaires ci-dessous, ce problème est davantage lié aux composants Android crash natif lors du défilement dans RecyclerView + CollapsingToolbarLayout

L'attribut AppCarLayout app:elevation="..dp" permet de résoudre ce problème
