android - 滚动视图不起作用

Question

（此处的所有屏幕截图：http: //imgur.com/a/uSQEe）您好，我正在为《使命召唤：黑色行动 2》开发完整指南。我已经基于并使用 ActionBarSherlockLibrary 和 SlidingMenu 库构建ScrollViews了GridViews布局: 它在 Android 4.0+ 中运行良好。但我对旧版本 Android 中的 Scroll（ScrollViews 和 GridViews）有疑问。 首先，我在我的 Corby 智能手机（Android 2.2）上对其进行了测试，而 ScrollView 根本不起作用。其次，我在 Android 2.3 模拟器上对其进行了测试：同样的故障。

这是此活动基于 GridView 的 Java 代码

        public class MainActivity extends SherlockActivity {
        final String pacchetto_app_prenium = Strings.PreniumPackage;
    final String prenium = Strings.prenium;

    final static String fallenangel  = "Fallen Angel";

一个建议，使用 strings.xml 来存储您的静态字符串。
