我无法匹配 textview 宽度

标签: android kotlin textview width tablelayout

这个问题吓到我了: 我从数据库中获取一些值,我想在表格中显示它们。我正在使用 2 个表格布局,因为我想在上面放一些标题和 1 个滚动条。我的想法是找到每列和它们的最大宽度,将这些值分配给标题文本视图,但它显示如下:

enter image description here

各种代码我都试过了;例如我使用 lp.width=resultado[0]tv1.width=resultado[0]。另一方面,如果我不写标题,我可以控制行的宽度,但是一旦我放置标题行,一切都会变得一团糟。

总结:我希望表格填满整个屏幕宽度并与标题匹配。

    }

P.S:知道这不是最简单的方法,但我正在测试它,一旦我得到正确的表格,我会改进应用程序。
