- Tabs at the top of the dialogViewPager

- Swipable, which content is connected to the TabsViewPager

, meaning the same buttons should remain at the bottom of the Dialog regardless of what Fragment

is showing.IllegalStateException: Fragment does not have a view

is suppose to be showing, plus the DialogFragment

I first tried to override onCreateView
, then onCreateDialog
and then both at the same time. All of which I got to run but with unexpected results.
onCreateView
: Can't reach the AlertDialog.Builder
to create the needed buttons, other than that the Dialog's results were great.onCreateDialog
: the error message shown above. I still imagine this method to be as close as I've gotten to what I want to achieve.onCreateView
and onCreateDialog
: Inflated the Dialog layout in onCreateView
and added the Dialog buttons to the AlertDialog.Builder
in onCreateDialog
. This displayed the dialog, but the added buttons from the AlertDialog.Builder
were not visable. Plus the keyboard didn't show up when clicking on a EditText
field.Most come from Tutorial to implement the use of TabHost in Android 2.2 + ViewPager and Fragments. The code of the ActivityFragment
is instead in a DialogFragment
. However I replaced its ViewPager with a modified one from the source code from this answer https://stackoverflow.com/a/18167273/2375978. This was to be able to wrap_content
on height.
The faulty code in my project is in DialogFragment
's onCreateDialog
method, I believe.
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), AlertDialog.THEME_HOLO_DARK);
LayoutInflater inflater = getActivity().getLayoutInflater();
view = inflater.inflate(R.layout.dialog_test, null);
addActionButtons(builder, view);
builder.setView(view);
mViewPager = (WrapContentHeightViewPager) view.findViewById(R.id.viewpager);
initialiseTabHost();
List<Fragment> fragments = getFragments();
pageAdapter = new DialogPageAdapter(getChildFragmentManager(), fragments);
mViewPager.setAdapter(pageAdapter);
mViewPager.setOnPageChangeListener(this);
Dialog dialog = builder.create();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
dialog.show();
return dialog;
}

I think I just ran into this same problem and learned a few things by looking at the source for DialogFragment.
It looks like even though overriding onCreateDialog(...) is a valid way to create a custom dialog, it will result in the DialogFragment having a null View, just like the error message says. In most cases this is fine - the DialogFragment doesn't need a View to show a Dialog, but if you want to nest fragments further (like you do), this won't fly.
Considering that you want to interact with an AlertDialog.Builder, there is really no perfect solution that I can see, but you've got a few options:
