示例1: onMeasure

 onMeasure(widthMeasureSpec, heightMeasureSpec) {
   let utils = require("utils/utils"),
     width = utils.layout.getMeasureSpecSize(widthMeasureSpec),
     widthMode = utils.layout.getMeasureSpecMode(widthMeasureSpec),
     height = utils.layout.getMeasureSpecSize(heightMeasureSpec),
     heightMode = utils.layout.getMeasureSpecMode(heightMeasureSpec),
     nativeWidth = this.nativeView ? (this.nativeView.image ? this.nativeView.image.size.width : 0) : 0,
     nativeHeight = this.nativeView ? (this.nativeView.image ? this.nativeView.image.size.height : 0) : 0,
     measureWidth = Math.max(nativeWidth, this.minWidth as number),
     measureHeight = Math.max(nativeHeight, this.minHeight as number),
     finiteWidth = widthMode !== utils.layout.UNSPECIFIED,
     finiteHeight = heightMode !== utils.layout.UNSPECIFIED;
   if (nativeWidth !== 0 && nativeHeight !== 0 && (finiteWidth || finiteHeight)) {
     let scale = this.computeScaleFactor(width, height, finiteWidth, finiteHeight, nativeWidth, nativeHeight, this.stretch),
       resultW = Math.floor(nativeWidth * scale.width),
       resultH = Math.floor(nativeHeight * scale.height);
     measureWidth = finiteWidth ? Math.min(resultW, width) : resultW;
     measureHeight = finiteHeight ? Math.min(resultH, height) : resultH;
     let trace = require("trace");
     trace.write("Image stretch: " + this.stretch +
       ", nativeWidth: " + nativeWidth +
       ", nativeHeight: " + nativeHeight, trace.categories.Layout);
   }
   let view = require("ui/core/view");
   let widthAndState = view.View.resolveSizeAndState(measureWidth, width, widthMode, 0);
   let heightAndState = view.View.resolveSizeAndState(measureHeight, height, heightMode, 0);
   this.setMeasuredDimension(widthAndState, heightAndState);

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);
    }
