Android AblistView:屏幕方向更改期间onRestoreInstanceState内的ClassCastException

我在几个片段和活动中使用了

AbsListView

，这样我就可以在纵向模式下使用

ListView

，在横向模式下使用

GridView

。我每天都用ICS和JB进行测试，效果很好。我开始在GB设备（2.3.6）上进行测试，当我在其中一个屏幕处于活动状态的情况下旋转设备时，我得到一个ClassCastException。以下是堆栈跟踪：

由于此视图的类型因方向而异，因此无需保存状态。通过

setSaveEnabled

禁用它将从

onSaveInstanceState

/

onRestoreInstanceState

事件中删除此控件

    list = (AbsListView) findViewById(R.id.list);
    list.setSaveEnabled(false);
