如何优化一个复杂的活动有 80 多个视图
[英]How to optimize a complex activity has more than 80 views
问题描述
概述：我正在尝试创建此活动，其中有X 个主题（在本例中为 12 个）每个主题都有自己的CardView ，每张卡片都有三个TextEdit ，它们计算该主题的平均值并将其显示在该卡片的TextView中，最后单击按钮后，它会显示另一个活动中所有主题的平均值。
问题：所以我对每张卡进行了硬编码，如您所见...（只有两张卡的代码和图像），我收到警告说此活动有超过 80 个视图，这对性能不利...
问题1 ：是否有任何解决方案可以优化活动而不使每张卡在单独的活动中？
问题 2 ：是否可以在 ListView 元素中创建一个 TextEdit 并分别获取每个 TextEdit 值（用于计算目的）？
