Its a example to implement DialogFragment. Please check the screenshots of running on Android Emulators of Android 4.1 Jelly Bean with API 16, Android 5.1 Lollipop with API 22 and Android 6.0 Marshmallow with API 23. If the emulator of Android 6.0 Marshmallow work properly, DialogFragment display wrong on Marshmallow.
