Keep value after closing dialog fragment

Question

I create dialog box by extending AppCompatDialogFragment(). I have one EditText field and Positive/Negative button. When I click on the Positive button I want to keep the value on the EditText, so when I reopen the dialog the value will be already written there.

Positive button (inside onCreateDialog()) - I send text to MainActivity

.setPositiveButton("apply", DialogInterface.OnClickListener(){ _: DialogInterface, _: Int ->
            (activity as MainActivity?)?.updateDelay(textDelay.text.toString())
        })

Does this answer your question? [How to store edit text data from an Android dialog?](https://stackoverflow.com/questions/27761497/how-to-store-edit-text-data-from-an-android-dialog) — Cyb3rKo, Sep 06 '20 at 15:49

You can use an interface which passes the value back if the dialog is closed:

If you want to permanently store the value and use it all around your project, you can also store it in Sharedpreferences.

Here`s an very simple tutorial of how to use SharedPreferences:

if you want to save this value while app is open use static value like in JAVA

public static String objectName = "";

and in Kotlin

companion object {

var objectName : String= ""
}
