Android：当接触外部时，如何删除DatePicker DialogFragment？

Question

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    super.onCreateDialog(savedInstanceState);

    DatePickerDialog picker = new DatePickerDialog(getActivity(),this,year,month,day);
    **picker.setCanceledOnTouchOutside(true);**
    return picker;

DatePickerFragment newFragment = new DatePickerFragment();
// tried the below also, with no luck
**newFragment.setCancelable(true);**
newFragment.show(getSupportFragmentManager(), "datePicker");

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
   ...
   getDialog().setCanceledOnTouchOutside(true);
   ... 
   }

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    if (getDialog() != null) {
        getDialog().setCanceledOnTouchOutside(true);
    }
    return super.onCreateView(inflater, container, savedInstanceState);
}    

我引用了这篇文章来寻找可能的答案：当在对话框外按下时，如何删除DialogFragment？。我在这里漏掉了什么？

Answer 1

如果要删除扩展DialogFragment的对话框，请写入

setCancelable（真）；

在OnCreateView内部。当你接触外面时，对话框将被取消。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
     setCancelable(true);
     return super.onCreateView(inflater, container, savedInstanceState);
}
