Question

在android中，是否可以通过编程方式从支持库中创建GridLayout（即不编写相应的xml）？

我在一个片段（名为PromotionLayoutFragment）中创建我的GridLayout，如下所示：

ViewGroup fragmentView = (ViewGroup)getView(); 
GridLayout gridLayout = new GridLayout(fragmentView.getContext());
gridLayout.setColumnCount(2);
gridLayout.setRowCount(15);
// add views to grid ...
fragmentView.addView(gridLayout);

当我使用API级别14中的GridLayout类时，这很好用，但是当我使用支持库（v7-r9）中的GridLayout时，我得到：

事实证明，您需要将GridLayout支持库包含为Android库项目（apklib），而不是jar。我正在使用maven Android SDK deployer，但目前有一个issue对此公开。
