示例2: onMeasure

    // This method won't be called in Android because we use the native android layout.
    public onMeasure(widthMeasureSpec: number, heightMeasureSpec: number): void {
        var result = view.View.measureChild(this, this.layoutView, widthMeasureSpec, heightMeasureSpec);

        var width = utils.layout.getMeasureSpecSize(widthMeasureSpec);
        var widthMode = utils.layout.getMeasureSpecMode(widthMeasureSpec);

        var height = utils.layout.getMeasureSpecSize(heightMeasureSpec);
        var heightMode = utils.layout.getMeasureSpecMode(heightMeasureSpec);

        var density = utils.layout.getDisplayDensity();
        var measureWidth = Math.max(result.measuredWidth, this.minWidth * density);
        var measureHeight = Math.max(result.measuredHeight, this.minHeight * density);

        var widthAndState = view.View.resolveSizeAndState(measureWidth, width, widthMode, 0);
        var heightAndState = view.View.resolveSizeAndState(measureHeight, height, heightMode, 0);

        this.setMeasuredDimension(widthAndState, heightAndState);
