Question

（此处的所有屏幕截图：http://imgur.com/a/uSQEe）嗨，我正在为“使命召唤：黑色行动2”制定完整的指南。我已经基于ScrollViews和GridViews构建了布局，并使用了ActionBarSherlockLibrary和SlidingMenu库：它在Android 4.0+中运行良好。但我在旧版Android中的Scroll（ScrollViews和GridViews）都存在问题。 首先，我在我的Corby智能手机（Android 2.2）上进行了测试，而ScrollView根本无效。第二个我在Android 2.3模拟器上测试过：相同的故障。

这是基于GridView

的此活动的Java代码
