tablerow不占用表格布局的全部宽度

Question

我对使用framelayouts的android中的tablelayouts有疑问。 但是，代码可以正常工作，但是我通过java添加的行与表未正确对齐，因此一开始就进行了总结。

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

我认为您还希望固定标题行。 我建议您使用此库https://github.com/InQBarna/TableFixHeaders 。 这样可以节省您很多时间。

Answer 2

在Java中动态设置日期的权重为textview，它们是日期，avg_speed等

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

其中1f等于1，则您可以根据需要给不同的权重。
