How to write preference values with androidx.preference:preference:1.1.1 in kotlin?

Question

I know that preference operation has upgraded to androidx.preference:preference:1.1.1

I can Code A to read the preference values "signature".

How can I write a new value to the preference values "signature" with androidx.preference:preference:1.1.1 in kotlin?

Code A

val sharedPreferences = PreferenceManager.getDefaultSharedPreferences(activity_context)
val name = sharedPreferences.getString("signature", "")

Answer 1

Use it like the old preference library:

val sharedPreferences = PreferenceManager.getDefaultSharedPreferences(activity_context)
sharedPreferences.edit().putString("signature", value).apply()

Just make sure that you import from:

import androidx.preference.PreferenceManager;
