View 测量宽高代码

    private int measureSize(int measureSpec) {
        int specMode = MeasureSpec.getMode(measureSpec);
        int specSize = MeasureSpec.getSize(measureSpec);
        //设置一个默认值，就是这个View的默认宽度为500，这个看我们自定义View的要求
        int result = 500;
        if (specMode == MeasureSpec.AT_MOST) {//相当于我们设置为wrap_content
            Log.i(TAG+"-measure"," wrap_content");
            result = Math.min(500, specSize);
        } else if (specMode == MeasureSpec.EXACTLY) {//相当于我们设置为match_parent或者为一个具体的值
            Log.i(TAG+"-measure"," match_parent or fix size");
            result = specSize;
        }
        return result;
    }

The issue contains only a Java measureSize snippet for an Android View and names no file, test, or requested change. Start by identifying whether the intended work is documentation or a code change, then locate the relevant blog entry; done requires a clearly stated outcome and a way to validate it.
