Android DialogFragment with AppCompat theme issue

Question

I've trying to create DialoFragment with AppCompat theme, but when i use AppCompat theme, dialog title is not shown.

I'am using defined style:

<style name="DialogFragment" parent="Theme.AppCompat.Light.Dialog"/>

When parent theme will be changed to:

<style name="DialogFragment" parent="android:Theme.Material.Light.Dialog"/>

or

<style name="DialogFragment" parent="android:Theme.Holo.Light.Dialog"/>

title is displaying properly.

Code of my dialog:

public class InfoDialog extends DialogFragment {

    public static final String TAG = InfoDialog.class.getName();

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.getWindow().setTitle(getString(R.string.dialog_title));

        return dialog;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(DialogFragment.STYLE_NORMAL, R.style.DialogFragment);
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.info_dialog, container, false);
    }
}

Any ideas what is causing the issue? Application use com.android.support:appcompat-v7:22.2.0, maybe this is platform bug?

Answer 1

Try extending AppCompatDialogFragment instead of DialogFragment. That should do the trick.

Answer 2

Theme.AppCompat.Light.Dialog sets no title window in default.

Try something like below:

<style name="DialogFragment" parent="Theme.AppCompat.Light.Dialog">
   <item name="android:windowNoTitle">false</item>
</style>
