android非法状态异常内容视图尚未创建?
嗨,当我启动抽屉活动片段时,会弹出“非法状态异常内容视图尚未创建”错误。这是我的代码和错误。我正在使用自定义列表适配器 错误:android非法状态异常内容视图尚未创建?,android,parse-platform,android-listfragment,Android,Parse Platform,Android Listfragment,嗨,当我启动抽屉活动片段时,会弹出“非法状态异常内容视图尚未创建”错误。这是我的代码和错误。我正在使用自定义列表适配器 错误: 10-14 09:40:25.926: E/AndroidRuntime(6736): java.lang.IllegalStateException: Content view not yet created 10-14 09:40:25.926: E/AndroidRuntime(6736): at android.app.ListFragment.ensu

我的oncreateview
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(
R.layout.fragment_home, container, false);
listview=(ListView) rootView.findViewById(android.R.id.list);
return rootView;
}
在恢复时调用mysetlist适配器
@Override
public void onResume() {
super.onResume();
ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("Shopinfo");
query.findInBackground(new FindCallback<ParseObject>() {
@Override
public void done(List<ParseObject> Shopinfo, ParseException e) {
// TODO Auto-generated method stub
if(e==null){
mShop=Shopinfo;
String[] spots = new String[mShop.size()];
int i = 0;
for(ParseObject Shopinfos : mShop) {
spots[i] = Shopinfos.getString(ParseConstants.KEY_SHOP_NAME);
i++;
}
if (getListView().getAdapter() == null) {
adapter=new ShopListAdapter(list.getContext(), mShop);
setListAdapter(adapter);
}
else {
((ShopListAdapter)getListView().getAdapter()).refill(mShop);
}
}
}
});
}
@覆盖
恢复时公开作废(){
super.onResume();
ParseQuery=新的ParseQuery(“Shopinfo”);
findInBackground(新的FindCallback(){

公共作废完成(列出Shopinfo,Parsee){

如果(e==null){

否则{

将以下内容移动到onActivityCreated()
方法或onViewCreated()
中

一个好的做法是将所有使用UI小部件的内容放在
方法的activitycreated()
方法中。从where isadapter=new ShopListAdapter(listview.getContext(),mShop)代码>和设置列表适配器(适配器)代码>被调用?尝试通过添加super.onCreateView(充气机、容器、savedInstanceState)来调用它们;在onCreateView部分中。我是否应该首先为片段创建视图?您应该在onCreateView()中这样做。
