使Commonsware TouchListView在TabGroup活动中起作用

Question

当我在TabGroupActivity中使用Commonsware TouchListView运行我的项目时，我可以看到ListView，但是当我试图拖动一个项目时，应用程序崩溃。我在日志中有这样的记录：

Answer 1

我不支持任何CWAC组件的选项卡式活动。这是一种官方弃用的技术。这从一开始就不是一个好主意，IMHO。

TouchListView代码来自一个Android开源应用程序，该应用程序不使用拖放活动中的选项卡。它用于拖动指示器的技术--将其作为视图添加到Window --可能不适用于选项卡中的活动。如果您将选项卡设置为以视图作为其内容，则可能会起作用，如您在this sample project中所见。
