android - 无法从自定义属性android获取值

Question

为什么总是默认值？

    private fun setupAttributes(attrs: AttributeSet?) {
        val typedArray = context.theme.obtainStyledAttributes(attrs, R.styleable.CustomView,
                0, 0)
        mColor = typedArray.getColor(R.styleable.CustomView_secondHandColor, Color.CYAN)
        paint.color = mColor
    }
