Ich habe in Android 8 (360dp x 640dp Gerät) getestet und alles ist in Ordnung, aber in Android 5.1.1 (320dp x 480dp Gerät) ist es deformiert, mein VectorDrawable-Bildschirm gefüllt und verliert das Seitenverhältnis. Wie kann ich das beheben?

@ ManiKandan Warum 24dp? Mein SVG ist kein Symbol, es ist eine große Illustration

@ManiKandan Ich habe den Beitrag aktualisiert und den vollständigen Vektor hinzugefügt

Ich habe es schon einmal gepostet, die erste XML ist mein Splash-Layout und die zweite XML ist Vektor, die dritte ist Thema

Ich hatte das gleiche Problem. Bitte schauen Sie sich meine Antwort hier an. Stackoverflow.com/questions/50327633/…

VectorDrawabledefiniert ein statisch zeichnbares Objekt. Ähnlich wie beim SVG-Format wird jede Vektorgrafik als Baumhierarchie definiert, die aus Pfad- und Gruppenobjekten besteht. Jeder Pfad enthält die Geometrie des Objektumrisses und die Gruppe enthält Details für die Transformation.

Sie können SDP verwenden - eine skalierbare Größeneinheit.

Ein Android SDK, das eine neue Größeneinheit bietet - sdp (skalierbares dp). Diese Größeneinheit skaliert mit der Bildschirmgröße. Es kann Android-Entwicklern bei der Unterstützung mehrerer Bildschirme helfen.

So fügen Sie Ihrem Projekt SDP hinzu (mit Android Studio und Gradle) build.gradle

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

Fügen Sie nun sdp anstelle von dp hinzu .

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

Hinweis - Verwenden Sie AppCompatImageView (With app:srcCompat) anstelle von ImageView in Ihrem Layout.

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

Aber hilft die Bildansicht tatsächlich, wenn ein Begrüßungsbildschirm "richtig" implementiert wird? Wenn es das Seitenverhältnis auf allen APIs
beibehält,

Das Problem hat mit den APIs 21, 22 und 23 zu tun, die Sie benötigen, um das Drawable um eine Bitmap zu wickeln. Sie müssen lediglich 2 Versionen Ihrer Liste mit zeichnbaren Ebenen erstellen und eine in drawable-v22 und die andere in drawable-v24 ablegen. Wenn diese Ordner noch nicht vorhanden sind, erstellen Sie sie einfach in res / und beachten Sie, dass Sie das Projekt festlegen müssen Ansicht zum Poject, um sie zu sehen (siehe Bild unten).

Für v24 verwenden Sie einfach die, die Sie bereits haben:

<?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>

Für drawable-v21 verwenden Sie Folgendes (beachten Sie, dass diese Drawable aus irgendeinem Grund nicht für APIs funktionieren, die höher als 23 sind).

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

</layer-list>
