Question

我对使用framelayouts的android中的tablelayouts有疑问。但是，代码可以工作，但是我通过java添加的行不能正确地与表格对齐，在开头包装。

我希望textviews与上面的图像Date，Session和speed正确对齐，我该怎么办？

Answer 1

我认为你也想要修复标题行。我建议你使用这个库https://github.com/InQBarna/TableFixHeaders。它会为你节省很多时间。

Answer 2

在java中动态设置权重为textview，即日期，avg_speed等，如

TextView txtview = new TextView(v.getContext());
LayoutParams params = new LinearLayout.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f);
txtview.setLayoutParams(params);

其中1f的权重为1，您可以根据需要提供不同的权重。

tablerow没有占据表格布局的全宽
