Android Spinner nie działa na urządzeniach Samsung z systemem Android 5.0

Question

Używam niestandardowego widgetu Spinner z poniższym kodem. Wszystko działa poprawnie na większości urządzeń, z wyjątkiem urządzeń Samsunga z Androidem 5.0. Po kliknięciu Spinner powinien wyświetlić listę wartości, ale tak się nie stanie.
Na emulatorach i innych urządzeniach marki z Androidem 5.0 działa dobrze.

Czy ktoś napotkał podobną osobę lub ma pojęcie o tym, co może się wydarzyć?

Z góry dzięki.

W końcu to naprawiłem!

Nieruchomość android clickable została ustawiona false, ale zachowanie kliknięcie przeprowadzono w pliku ComboBoxView.java na poniższym kodzie:

private final OnClickListener onClick = new OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     mSpinner.performClick(); 
    } 
}; 

to działa wszędzie (urządzenia i emulatory) z wyjątkiem urządzeń Samsung z Android 5.0. To nie mogłem zrozumieć dlaczego.

Po zmianie właściwości cliclabke na true, zaczęło działać.

android:clickable="true" 

Dzięki.
