我已经在SO上尝试过类似问题的引用,但是没有得到合适的解决方案。
我正在尝试从网页中获取数据,并以包含4列的行的格式显示。
网页上显示的数据:
SBIN ;1916.00;1886.85;1.54@LT ;1315.50;1310.30;0.40@TCS ;1180.00;1178.00;0.17@AXISBANK ;1031.30;1005.95;2.52@MARUTI ;1000.35;992.35;0.81@PNB ;931.90;916.35;1.70@GAIL ;400.00;398.45;0.39@
我想以
的形式透露它SBIN.........1916.00.....1886.85.....1.54
LT...........1315.50.....1310.30.....0.40 and so on.
请注意,我不想要点,我希望每个值都是一行中的单独列。
我的数据包含7行。
当我运行以下代码时,我得到此输出 即。
values[0] values[1] values[2] values[3]
values[1] values[2] values[3] values[4]
values[2] values[3] values[4] values[5]
(打印第1行的所有4个col,然后是第1行的第2-4列和第2行的col1,然后是第1行的3-4和第2行的第1-2行,依此类推......)

尝试使用ListView
而不是TableLayout将ListView添加到xml中,并将内容放在新xml中的表中 通过扩展ArrayAdapter创建适配器,并在listView上设置此适配器。
答案 1 :(得分:0)
不要在Java代码中添加视图,因为它们是根据您的XML文件添加的。在我看来,你的Java代码重复了你在XML中做的非常不稳定的事情......
我不明白为什么你不能只删除Java代码并使用setContentView
来使用你定义的XML布局。

将宽度设置为0,并为所有测试视图添加权重1,它将为行中的每个项目均匀分配空间。
textView1.setWidth(0);
textView1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f));
