android表行需要以行的百分比换行

Question

我有以下代码，我需要每个表格行的第二行以屏幕宽度的百分比换行……比如 80%。 它的textview3 字段需要换行，同时将row1 保留在屏幕上。

应该是

---

RowOneLeft RowOneRight

这一行应该重新换行\n

一次又一次

一次又一次。

检查PercentRelativeLayout。

您可以在xml中设置百分比宽度：

  app:layout_widthPercent="80%"

或在代码中：

PercentLayoutHelper.PercentLayoutParams params =(PercentLayoutHelper.PercentLayoutParams) view.getLayoutParams();
PercentLayoutHelper.PercentLayoutInfo info = params.getPercentLayoutInfo();
info.widthPercent = 80;
