class CircleView : ViewGroup, View.OnTouchListener { 

private var controller: SpeedControllerImp? = null 

constructor(context: Context) : super(context) { 
    init() 
} 

constructor(context: Context, attrs: AttributeSet?) : super(context, attrs) { 
    var mTextView = TextView(this.context) 
    mTextView?.setTextColor(Color.WHITE) 
    mTextView?.textSize = 150F 
    val params = LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT) 
    mTextView?.layoutParams = params 
    mTextView?.text = "asdasadasdasdasdasdasdasdasdasdasdasdasdas" 

    this.addView(mTextView) 
    init() 
}

/*覆盖乐趣onMeasure（widthMeasureSpec：诠释，heightMeasureSpec：诠释）{

val count = childCount 
    for (i in 0..count - 1) { 
     var childView = getChildAt(i) 
     childView.measure(widthMeasureSpec, heightMeasureSpec) 
    } 
    super.onMeasure(widthMeasureSpec, heightMeasureSpec) 
}

} 

override fun onDraw(canvas: Canvas) { 
    super.onDraw(canvas) 
    controller?.onDraw(canvas) 
    invalidate() 
} 

override fun onSizeChanged(w: Int, h: Int, oldw: Int, oldh: Int) { 
    controller?.onSizeChanged(w, h) 
    super.onSizeChanged(w, h, oldw, oldh) 
} 

override fun onTouch(v: View, event: MotionEvent): Boolean { 
    controller?.onTouchEvent(event) 
    return true 
} 

private fun init() { 
    setWillNotDraw(false) 
    setOnTouchListener(this) 
    controller = SpeedControllerImp() 
}

} fun onMeasure不帮我（我的错误在哪里？
