Android群英传 3.2View的测量代码@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { setMeasuredDimension( measureWidth(widthMeasureSpec), measureHeight(heightMeasureSpec));}private int measureWidth(int measureSpec) { int result = 0; int specMode = MeasureSpec.getMode(measureSpec); int specSize = MeasureSpec.getSize(measureSpec); if (specMode == MeasureSpec.EXACTLY) { result = specSize; } else { result = 200; if (specMode == MeasureSpec.AT_MOST) { result = Math.min(result, specSize); } } return result;}请问下划线的if语句有什么作用呢？前面result = 200 不是已经设置自定义View的wrap_content默认值为200px了么？
