requestFeature() must be called before adding content in fragment in android

Question

I want to show fragment in activity without no title bar. i also have added request window without title bar before inflating the views. this is not happening and it is showing exception as

requestFeature() must be called before adding content
    at com.android.internal.policy.impl.PhoneWindow.requestFeature(PhoneWindow.java:318)
    at com.wishkart.wishkart.dialogFragment.HomeProductDialogFragment.onCreateView(HomeProductDialogFragment.java:30)

My fragment code is given as:

 public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    getActivity().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
    getActivity().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    View view = inflater.inflate(R.layout.custom_product_popup, container, false);
    return view;
}

Try moving it to the onCreate on the activity before setContentView is called. — Elletlar, Jul 14 '18 at 11:50
A fragment must be contained inside an Activity. The FEATURE_NO_TITLE is part of the Window/Activity. Did you try what I suggested? — Elletlar, Jul 14 '18 at 12:11

The problem is that views have already been added when SetContentView is called which happens before onCreateView in the fragment. The solution is to ensure FEATURE_NO_TITLE is requested before the call to setContentView.

Inside the enclosing Activity:

@Override
protected void onCreate(
final Bundle savedInstanceState)
{
  super.onCreate(savedInstanceState);

  // Hide the Title bar of this activity screen
  getWindow().requestFeature(Window.FEATURE_NO_TITLE);

  setContentView(R.layout.main);
  ...
}

You could also hide it inside the fragment like this:

 @Override
  public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        ((AppCompatActivity)getActivity()).getSupportActionBar().hide();
  }

Or getActivity().getActionBar() if the support library is not being used.

Note: Call show() to restore the ActionBar.

But I would advise doing it from the Activity if you are going to do it in code.

But the most maintainable framework friendly way to hide the bar is to use a style rather than doing it in code:

Hiding the ActionBar with a theme

In my activity i am showing many fragment but I want to hide title bar for one fragment and other will remain same. — Anser Abbas, Jul 14 '18 at 12:34
Okay. The original post was asking about how to get rid of requestFeature error which I think I've answered...But see the other solution that I just added, hide() and show() can be called on the ActionBar from within the fragment. — Elletlar, Jul 14 '18 at 12:41
