heightMeasureSpec = widthMeasureSpec = MeasureSpec.makeMeasureSpec（childWidthSize，MeasureSpec.EXACTLY）是什么意思？

Question

在下面的示例代码中，我找到heightMeasureSpec = widthMeasureSpec = MeasureSpec.makeMeasureSpec（childWidthSize，MeasureSpec.EXACTLY）。 代码中有两个“=”，是不是？这是Java语法吗？

   @SuppressWarnings("unused")
    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        setMeasuredDimension(getDefaultSize(0, widthMeasureSpec), getDefaultSize(0, heightMeasureSpec));

        int childWidthSize = getMeasuredWidth();
        int childHeightSize = getMeasuredHeight();

        heightMeasureSpec = widthMeasureSpec = MeasureSpec.makeMeasureSpec(childWidthSize, MeasureSpec.EXACTLY);
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }

Answer 1

是的，它在Java中是允许的。它将heightMeasureSpec和widthMeasureSpec设置为MeasureSpec.makeMeasureSpec(childWidthSize, MeasureSpec.EXACTLY)返回的值。
