android - How to change the Theme of an activity after it is created? -

after creating activity, how can alter theme new one, example, theme.holo.

is possible?

you cannot alter theme of activity after created. can alter theme before views added, not after.

as per the docs settheme(int):

note should called before views instantiated in context (for illustration before calling setcontentview(view) or inflate(int, viewgroup)).

if wish alter theme before views added, can in oncreate() so:

public void oncreate(bundle savedinstancestate) { settheme(mythemeresourceid); super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); }
