当我将onCreateDialog方法添加到DialogFragment类时，我的应用程序崩溃了。如果我不添加该方法，则会显示包含列表的对话框。我经历了其他类似的话题，但它无法解决我的问题。拜托，我可以在这里使用一些帮助。这是我的代码。
public class SubVitalsEntryDialogFragment extends DialogFragment {
ArrayList<SubVitals> subVitalList = new ArrayList<SubVitals>();
ListView mylist;
public static SubVitalsEntryDialogFragment newInstance(ArrayList<SubVitals> sub) {
SubVitalsEntryDialogFragment f = new SubVitalsEntryDialogFragment();
// Supply num input as an argument.
Bundle args = new Bundle();
args.putParcelableArrayList("subVitalList", sub);
f.setArguments(args);
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.subvitals_dialog_layout, null, false);
mylist = (ListView) view.findViewById(R.id.vitalEntryListView);
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return view;
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
subVitalList = getArguments().getParcelableArrayList("subVitalList");
ArrayAdapter<SubVitals> adapter = new MyListAdapter(subVitalList);
mylist.setAdapter(adapter);
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder alertDialogBuilder = null;
alertDialogBuilder = new AlertDialog.Builder(getActivity());
//View view = getActivity().getLayoutInflater().inflate(R.layout.subvitals_dialog_layout, null);
//alertDialogBuilder.setView(view);
alertDialogBuilder.setTitle("Enter your vital");
alertDialogBuilder.setPositiveButton("Cancel", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
dialog.dismiss();
}
});
return alertDialogBuilder.create();
}
private class MyListAdapter extends ArrayAdapter<SubVitals>{
public MyListAdapter(ArrayList<SubVitals> subVitalList){
super(getActivity(), R.layout.subvitals_dialog_layout, subVitalList);
Log.d("Tag", "super okay");
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
//return super.getView(position, convertView, parent);
//Making sure we've a view to work with(may have been given null
Log.d("TAG","Inside get view");
View itemView = convertView;
if (itemView == null)
itemView = LayoutInflater.from(this.getContext()).inflate(R.layout.sub_vital_template, parent, false);
String currentVital = subVitalList.get(position).getSubVitalName();
//Fill the view
TextView vitalText = (TextView) itemView.findViewById((R.id.vitalEntryListView));
vitalText.setText(currentVital);
return itemView;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return subVitalList.size();
}
}
}

答案 0 :(得分：1)
替换
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
与
getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);
并在onViewCreated()中执行此操作，而不是onCreateView()：
@Override
public void onViewCreated(final View view, Bundle savedInstanceState){
getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);
}
