我正在获得一个只在我使用genymotion时发生的类强制转换异常。每当我在真实设备上尝试这个时，我都没有问题。

我正在使用Commonsware的合并适配器和代码：

更新：Commonsware向我展示了如何解决这个问题。我需要传入ListView作为我添加到合并适配器的视图的容器。然后将代码移到onViewCreated，
以下是更新后的代码：
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
ListView listView = getListView();
initViews(listView, view);
setViews();
setListAdapter(mergeAdapter);
}
现在initViews只从主机活动中获取LayoutInflater。
public void initViews(ViewGroup container, View v) {
LayoutInflater inflater = getActivity().getLayoutInflater();
....
感谢您的帮助！
答案 0 :(得分：1)
在initViews()中，您需要将inflate()来电的第二个参数设为ListView。这不是你所拥有的 - 你正在传递放置这个片段的容器。更改initViews()以在其ListView来电中使用inflate()，您应该会有更好的结果。
虽然说实话，如果我对你的代码的解释是正确的，我会期待你在任何Android环境中崩溃，而不仅仅是Genymotion模拟器。
