效果图：

Step 1 - 引入 svgknife.aar

Step 2 - 自定义个View画解析出来的Path

import android.content.Context
import android.graphics.Canvas
import android.graphics.Color
import android.graphics.Paint
import android.util.AttributeSet
import android.view.View
import androidx.annotation.RawRes
import com.looper.android.svgknife.SvgKnife.SvgPath

class BloomImageView @JvmOverloads constructor(
    context: Context,
    attributeSet: AttributeSet? = null
) : View(context, attributeSet) {

    private val paint = Paint(Paint.ANTI_ALIAS_FLAG).apply {
        style = Paint.Style.STROKE
        color = Color.RED
        strokeWidth = 4f
        // 核心是设置一个 ShadowLayer
        setShadowLayer(10f, 0f, 0f, Color.RED)
    }

    private val svgKnife = SvgKnife(paint)

    private var bloomIconPaths = mutableListOf<SvgPath>()

    fun setBloomIcon(@RawRes rawRes: Int) {
        bloomIconPaths.clear()
        svgKnife.load(context, rawRes)
        invalidate()
    }

    override fun onDraw(canvas: Canvas) {
        super.onDraw(canvas)

        if (bloomIconPaths.isEmpty()) {
            bloomIconPaths.addAll(svgKnife.getPathsForViewport(width, height))
        }

        bloomIconPaths.forEach {
            canvas.drawPath(it.path, paint)
        }
    }
}
