像那样

是否可以？

用组标签包裹你的路径标签。然后在组标签中添加属性scaleX、scaleY、pivotX和pivotY以创建填充效果。像这样：

<vector xmlns:android="http://schemas.android.com/apk/res/android"
        android:width="48dp"
        android:height="48dp"
        android:alpha="0.6"
        android:viewportHeight="24.0"
        android:viewportWidth="24.0">
    <group
        android:scaleX="0.5"
        android:scaleY="0.5"
        android:pivotX="12"
        android:pivotY="12">
        <path
            android:fillColor="#FF000000"
            android:pathData="M3,4L3,1h2v3h3v2L5,6v3L3,9L3,6L0,6L0,4h3zM6,10L6,7h3L9,4h7l1.83,2L21,6c1.1,0 2,0.9 2,2v12c0,1.1 -0.9,2 -2,2L5,22c-1.1,0 -2,-0.9 -2,-2L3,10h3zM13,19c2.76,0 5,-2.24 5,-5s-2.24,-5 -5,-5 -5,2.24 -5,5 2.24,5 5,5zM9.8,14c0,1.77 1.43,3.2 3.2,3.2s3.2,-1.43 3.2,-3.2 -1.43,-3.2 -3.2,-3.2 -3.2,1.43 -3.2,3.2z"/>
    </group>

</vector>

*枢轴值取决于向量的宽度和高度的大小
