How to open ListPreference automatically when activity is started

Question

I have two activities - MainActivity and PrefActivity . MainActivity - activity with button, when I click on it, it refer me to the PrefActivity PrefActivity - preferenceactivity with ListPreference .

How to open or click on the ListPreference automatically while PrefActivity is opening?

Answer 1

Use startActivityForResult to transfer control from MainActivity to PrefActivity. Once complete you'll return control back to MainActivity.

That said, you'll typically only want to automatically direct users to preferences the first time they use the app. In that case you can use Shared Preferences to record that prefs have been set. (Eg, flip sharedPref boolean value to true.)
