【问题描述】：
我得到一个类转换异常，该异常仅在我使用 genymotion 时发生。每当我在真实设备上尝试时，我都没有问题。

我正在使用 Commonsware 和代码的合并适配器：

ViewGroup v = (ViewGroup) inflater.inflate(R.layout.fragment_profile_merge_list, container, false);
initViews(inflater, container, v);

setListAdapter(mergeAdapter);
return v;
}

profileHeaderRL = (RelativeLayout) inflater.inflate(R.layout.profile_header_layout, container, false);
contactInfoRL = (RelativeLayout) inflater.inflate(R.layout.profile_contact_info_layout, container, false);
addressRL = (RelativeLayout) inflater.inflate(R.layout.profile_address_layout, container, false);
listingInfoRL = (RelativeLayout) inflater.inflate(R.layout.profile_listing_info_layout, container, false);

nameTV.setText(hsProfileData.getFirstName() + " " + hsProfileData.getLastName());

HomeStoryApplication.getInstance().getPicasso(getActivity()).
load(HSApiController.getInstance().getClientProfileImageURL(profileId))
.fit()
.centerCrop()
.into(profileIV, new Callback.EmptyCallback() {
public void onSuccess() {
initialsTV.setVisibility(View.GONE);

});
doneTV.setOnClickListener(new View.OnClickListener() {
@Override

editTV.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
switch (profileMode) {
case AGENT_MODE:
Intent editAgentProfileIntent = new Intent(getActivity(), AddNewSearchActivity.class);
editAgentProfileIntent.putExtra(PROFILE_ID, profileId);
editAgentProfileIntent.putExtra(PROFILE_MODE, AGENT_MODE);
startActivity(editAgentProfileIntent);
break;
case SEARCH_MODE:
Intent editSearchIntent = new Intent(getActivity(), AddNewSearchActivity.class);
editSearchIntent.putExtra(PROFILE_ID, profileId);
editSearchIntent.putExtra(PROFILE_MODE, SEARCH_MODE);
startActivity(editSearchIntent);
break;
case LISTING_MODE:
Intent editListingIntent = new Intent(getActivity(), AddNewListingActivity.class);
editListingIntent.putExtra(AddNewListingActivity.EXTRA_PROFILE_ID, listing.getProfileID());
startActivity(editListingIntent);
break;
}
}
});
}
更新：Commonsware 向我展示了如何解决该问题。我需要将 ListView 作为要添加到合并适配器的视图的容器传入。然后把代码移到onViewCreated，
这是更新后的代码：
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
ListView listView = getListView();
initViews(listView, view);
setViews();
setListAdapter(mergeAdapter);
}
现在 initViews 只是从宿主活动中获取 LayoutInflater。
public void initViews(ViewGroup container, View v) {
LayoutInflater inflater = getActivity().getLayoutInflater();
....
感谢您的帮助！
