Testowałem na Androidzie 8 (urządzenie 360dp x 640dp) i wszystko jest w porządku, ale w Androidzie 5.1.1 (urządzenie 320dp x 480dp) jest zdeformowane, mój ekran wypełniony VectorDrawable i stracił proporcje, jak to naprawić?

i motyw

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
        <!-- Show a splash screen on the activity. Automatically removed when
             Flutter draws its first frame -->
        <item name="android:windowBackground">@drawable/launch_background</item>
    </style>
</resources>

@ManiKandan Dlaczego 24dp ?? mój SVG nie jest ikoną, to duża ilustracja
WebMaster

@ManiKandan Zaktualizowałem post i dodałem pełny wektor
WebMaster

Opublikowałem to wcześniej, pierwszy xml to mój układ powitalny, a drugi xml jest wektorowy, trzeci to motyw
WebMaster

Miałem ten sam problem, proszę spojrzeć na moją odpowiedź tutaj stackoverflow.com/questions/50327633/...

VectorDrawabledefiniuje nieruchomy obiekt rysowany. Podobnie do formatu SVG, każda grafika wektorowa jest zdefiniowana jako hierarchia drzewa, na którą składają się obiekty ścieżki i grupy. Każda ścieżka zawiera geometrię konturu obiektu, a grupa zawiera szczegóły dotyczące transformacji.

Możesz użyć SDP - skalowalnej jednostki rozmiaru.

Android SDK, który zapewnia nową jednostkę wielkości - sdp (skalowalny dp). Ta jednostka wielkości skaluje się wraz z rozmiarem ekranu. Może pomóc programistom Androida w obsłudze wielu ekranów.

Aby dodać SDP do swojego projektu (Korzystanie z Android Studio i Gradle) build.gradle

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

Teraz dodaj sdp zamiast 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">

Uwaga - Użyj układu AppCompatImageView (With app:srcCompat) zamiast ImageView w układzie.

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

ale czy podgląd obrazu faktycznie pomaga przy wdrażaniu ekranu powitalnego „we właściwy sposób”? w każdym razie, jeśli zachowuje proporcje wszystkich interfejsów API, myślę, że to działa

Problem dotyczy API 21, 22 i 23 dla tych, którzy muszą owijać mapę do rysowania wokół mapy bitowej. co musisz zrobić, to utworzyć 2 wersje listy warstw do rysowania i umieścić jedną w drawable-v22, a drugą w drawable-v24, jeśli te foldery jeszcze nie istnieją, po prostu utwórz je w res / i pamiętaj, że musisz ustawić projekt zobacz, aby zobaczyć, aby je zobaczyć (patrz zdjęcie poniżej).

w wersji v24 wystarczy użyć tego, który już masz:

<?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>

dla drawable-v21 używasz następujących (zwróć uwagę, że z jakiegoś powodu te drawable nie będą działać na API wyższych niż 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"
        android:src="@drawable/splash_screen" />
</item>

</layer-list>
