How to set the title of DialogFragment?
AndroidAndroid FragmentsAndroid DialogfragmentAndroid Problem Overview
This should be a simple task, but for some reason I can find a way to set the title of a DialogFragment. (I am setting the dialog contents using onCreateView
overload).
The default style leaves a place for the title, but I can't find any method on the DialogFragment
class to set it.
The title is somehow magically set when the onCreateDialog
method is used to set the contents, so I wonder if this is by design, or there is a special trick to set it when using the onCreateView
overload.

You can use getDialog().setTitle("My Dialog Title")
Just like this:
public static class MyDialogFragment extends DialogFragment {
...
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// Set title for this dialog
getDialog().setTitle("My Dialog Title");
View v = inflater.inflate(R.layout.mydialog, container, false);
// ...
return v;
}
// ...
}

Does overriding onCreateDialog
and setting the title directly on the Dialog
work? Like this:
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.setTitle("My Title");
return dialog;
}

Jason's answer used to work for me, but now it needs the following additions to get the title to show.
Firstly, in your MyDialogFragment's onCreate()
method, add:
setStyle(DialogFragment.STYLE_NORMAL, R.style.MyDialogFragmentStyle);
Then, in your styles.xml file, add:
<style name="MyDialogFragmentStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">false</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">false</item>
</style>
After hours of trying different things, this is the only one that has done the trick for me.
NB - You may need to change the Theme.AppCompat.Light.Dialog.Alert
to something else in order to match the style of your theme.

DialogFragment could be represented as dialog and as Activity. Use code below that would work properly for both
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if (getShowsDialog()) {
getDialog().setTitle(marketName);
} else {
getActivity().setTitle(marketName);
}
}

You can take a look at the official docs. The way i did is like this:
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity())
.setTitle("My Title");
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.my_layout, null);
builder.setView(view);
return builder.create();
}

Similar to Ban Geoengineering's answer, but with a few modifications, so instead of coding what specific theme to use in the DialogFragment
, I override the default style used by DialogFragment
s in my styles.xml
.
set the title in the androidx.fragment.app.DialogFragment
.
class EditBatteryLevelFragment:DialogFragment(),SelfClosingFragment.Host
{
override fun onCreateView(
inflater:LayoutInflater,container:ViewGroup?,savedInstanceState:Bundle?
):View
{
// set dialog title
requireDialog().setTitle(R.string.edit_battery_level__title)
// .....
return someView
}
}
in your app theme in styles.xml
, override android:dialogTheme
, which is the default style used by DialogFragment
instances.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="Theme.MaterialComponents">
<!-- BONUS READING: override material colors here, too https://material.io/develop/android/theming/color -->
<!-- override DialogFragment theme of those spawned by activities with this theme -->
<item name="android:dialogTheme">@style/AppTheme.Dialog</item>
</style>
<!-- ... -->
also in styles.xml
, declare the dialog theme that will be used by DialogFragment
instances. it's important for this style to inherit from ThemeOverlay
so that it will preserve your app's theme colors.
<!-- ... -->
<!-- define the style for your dialog -->
<style name="AppTheme.Dialog" parent="ThemeOverlay.MaterialComponents.Dialog">
<!-- add a minimun width to the dialog, so it's not too narrow -->
<item name="android:windowMinWidthMajor">@dimen/abc_dialog_min_width_major</item>
<item name="android:windowMinWidthMinor">@dimen/abc_dialog_min_width_minor</item>
<!-- display the title for dialogs -->
<item name="android:windowNoTitle">false</item>
</style>
</resources>
make sure that the activity that is spawning the DialogFragment
is using the defined AppTheme
.

If you are using view binding:
@NonNull
@Override
public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
binding = YourDialogXmlBinding.inflate(getLayoutInflater());
AlertDialog.Builder builder = new AlertDialog.Builder(requireActivity());
builder.setTitle("Your title here")
.setView(binding.getRoot());
return builder.create();
}
