J'ai testé dans Android 8 (appareil 360dp x 640dp) et tout va bien, mais dans Android 5.1.1 (appareil 320dp x 480dp) il est déformé, mon écran rempli VectorDrawable et son rapport d'aspect lâche, comment puis-je le réparer?

et le thème

@ManiKandan Pourquoi 24dp ?? mon SVG n'est pas une icône, c'est une grande illustration
— WebMaster
@ManiKandan J'ai mis à jour le message et ajouté le vecteur complet

Je l'ai posté avant, le premier xml est ma mise en page splash et le deuxième xml est vectoriel, le troisième est le thème

J'ai eu le même problème, veuillez regarder ma réponse ici stackoverflow.com/questions/50327633/…

VectorDrawabledéfinit un objet dessinable statique. Semblable au format SVG, chaque graphique vectoriel est défini comme une hiérarchie arborescente, composée d'objets de chemin et de groupe. Chaque chemin contient la géométrie du contour de l'objet et le groupe contient les détails de la transformation.

Vous pouvez utiliser SDP - une unité de taille évolutive.

Un SDK Android qui fournit une nouvelle unité de taille - sdp (dp évolutif). Cette unité de taille évolue avec la taille de l'écran. Il peut aider les développeurs Android à prendre en charge plusieurs écrans.

Pour ajouter sdp à votre projet (à l'aide d'Android Studio et de Gradle) build.gradle

dependencies {
  implementation 'com.intuit.sdp:sdp-android:1.0.6'
}

Ajoutez maintenant sdp au lieu de dp .

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="@dimen/_300sdp"
    android:height="@dimen/_225sdp"
    android:viewportWidth="512"
    android:viewportHeight="512">

Remarque - Utilisez AppCompatImageView (With app:srcCompat) au lieu d' ImageView dans votre mise en page.

 <android.support.v7.widget.AppCompatImageView //Or androidx.appcompat.widget.AppCompatImageView
    app:srcCompat="@drawable/your_svg"
    />

mais imageview aide-t-elle réellement lors de l'implémentation d'un écran de démarrage de la "bonne" façon? de toute façon si elle préserve le rapport d'aspect sur toutes les API, je suppose que cela fonctionne

Le problème est lié aux API 21, 22 et 23 pour ceux dont vous avez besoin pour enrouler le dessin autour d'une image bitmap. ce que vous devez faire est de créer 2 versions de votre liste de calques dessinables et d'en mettre une dans drawable-v22 et l'autre dans drawable-v24, si ces dossiers n'existent pas déjà, créez-les dans res / et notez que vous devez définir le projet vue à pojecter pour les voir (voir image ci-dessous).

pour v24, vous utilisez simplement celui que vous avez déjà:

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:drawable="@android:color/white"
    android:gravity="fill" />

<item

    android:gravity="center"
    android:src="@drawable/splash_screen" >
</item>

</layer-list>

pour drawable-v21, vous utilisez les éléments suivants (notez que pour une raison quelconque, ces drawables ne fonctionneront pas sur les API supérieures à 23)

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:drawable="@android:color/white"
    android:gravity="fill" />

<item android:gravity="center">
    <bitmap
        android:gravity="center"
