Как сделать векторное изображение градиентом?

Мы можем сделать векторный градиент, объединив вектор и форму. Чтобы объединить вектор и форму, мы должны создать список слоев, как показано ниже:

<?xml version = "1.0" encoding = "utf-8"?>
<layer-list xmlns:android = "http://schemas.android.com/apk/res/android">
    <item>
        <vector xmlns:android = "http://schemas.android.com/apk/res/android"
            android:width = "1024.000000dp"
            android:height = "1024.000000dp"
            android:viewportWidth = "1024.000000"
            android:viewportHeight = "1024.000000">

            <group
                android:translateY = "1024.000000"
                android:scaleX = "0.100000"
                android:scaleY = "-0.100000">
                <path
                    android:fillColor = "#000000"
                    android:strokeWidth = "1"
                    android:pathData = "M4750 10229 c-1481 -111 -2824 -843 -3722 -2029 -327 -433 -603 -959 -772 -1475 -238 -726 -312

            </group>
        </vector>
    </item>

    <item>
        <shape xmlns:android = "http://schemas.android.com/apk/res/android"
            android:shape = "oval">
            <solid android:color = "#8df"/>
            <size
                android:width = "48dp"
                android:height = "48dp"
                />
            <gradient android:centerColor = "@android:color/holo_purple"
                android:startColor = "@android:color/holo_red_dark"
                android:endColor = "@android:color/holo_green_dark"
                />
        </shape>

Привет, если вы хотите изображение выше без значка, вот обновленный ответ:

<?xml version = "1.0" encoding = "utf-8"?>
<layer-list xmlns:android = "http://schemas.android.com/apk/res/android">
    <item
        android:width = "1024dp"
        android:height = "1024dp">
        <shape xmlns:android = "http://schemas.android.com/apk/res/android"
            android:shape = "oval">
            <gradient
                android:startColor = "@color/color1"
                android:centerColor = "@color/color2"
                android:endColor = "@color/color3"
                />
        </shape>
    </item>

    <item
        android:width = "900dp"
        android:height = "900dp"
        android:gravity = "center">
        <shape xmlns:android = "http://schemas.android.com/apk/res/android"
            android:shape = "oval">
            <gradient
                android:startColor = "@color/color4"
                android:centerColor = "@color/color5"
                android:endColor = "@color/color6"
                />
        </shape>
    </item>

Я попытался создать инструмент по умолчанию для Android-студии Векторные активы.

С помощью этого инструмента я создал значок Instagram.

<vector android:height = "24dp" android:viewportHeight = "1024"
    android:viewportWidth = "1024" android:width = "24dp"
