在android中，是否可以完全从支持库中以编程方式创建GridLayout(即，无需编写相应的xml)？
我在一个 fragment (称为PromotionLayoutFragment)中创建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中存在的GridLayout类时，此方法工作正常，但是当我使用支持库(v7-r9)中的GridLayout时，我得到:

最佳答案
原来，您需要将GridLayout支持库作为一个Android库项目(apklib)而不是jar包含在内。我正在使用maven Android SDK deployer，但是目前对此有一个issue打开。
