如何在< API 24中使用带有渐变的矢量绘图？

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24"
    android:viewportHeight="24">
    
    <path
        android:fillColor="#000000"
        android:pathData="M12,2L1,21h22L12,2z" />
        
    <gradient
        android:startColor="#FF0000"
        android:endColor="#0000FF"
        android:type="linear"
        android:angle="45" />
</vector>

ImageView imageView = findViewById(R.id.imageView);
Drawable drawable = VectorDrawableCompat.create(getResources(), R.drawable.gradient_vector, getTheme());
imageView.setImageDrawable(drawable);
