EditTextPreference with false persistent does not call onSharedPreferenceChanged

I've this EditTextPreference

<EditTextPreference
        android:title="@string/settings_server"
        android:summary="@string/server_name_message"
        android:persistent="false"
        android:key="SERVER_NAME" />

But with persistent="false" it does not call onSharedPreferenceChanged method. How can I detect this event keeping android:persistent="false"

You'll have to attach custom listener in code of your PreferenceActivity or PreferenceFragment:

EditTextPreference prefServerName = (EditTextPreference) findPreference("SERVER_NAME");

prefServerName.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
    @Override
    public boolean onPreferenceChange(Preference preference, Object newValue) {
        String value = (String) newValue;

        // do what you need

        return true; // indicates you processed the new value
    }
});
