我的列名行为受阿雷拉·阿达普特的约束,在那里,我凌驾于“意见”方法之上。 如果我改变这种方法中植被的可见度或改变这种观点的背景颜色,这些变化一旦在屏幕上滚动后修改了项目清单,就会消失。 事实上,名单上的其他一些观点正在讨论这些变化。

我如何看待经过修改的看法,然后在滚动之后重新展示?

最佳回答

您是否每次都fl新观点,或利用变本 观点已经通过?

通常,改编者试图回收意见,只是创造出足以提供平稳的滚动。 现有的循环意见作为转换意见通过。 无论何时(计算费用)或仅仅根据职位重新设立改写意见(如果存在的话),你都可以孤立和重新提出新观点。 如果回收,你需要重新确定所有观点属性,因为没有保证你过去曾被循环使用的观点与这一立场相同。

象你一样,你不正确地重新确定循环观点的所有属性(垂直意见),以便与目前情况的数据相匹配。
