Dialogfragment - Setting Initial Values And Retaining State After Rotation

I have created an DialogFragment which is building and returning AlertDialog from onCreateDialog method. The AlertDialog contains two EditText views. I'm setting the initial value

Solution 1:

Calendar is Serializable so you can put it as that in the Bundle.

Solution 2:

You can store your data in onSaveInstanceState(Bundle outState) method, and read them again in onRestoreInstanceState() method. onSaveInstanceState will be called before screen rotation, and onRestoreInstanceState() after change. This is a good place to store data between orientation changes.

Or you can also add in Manifest file

android:configChanges="orientation"

Add this value to activitiy, which contains your alertDialog.
