How to set a theme to whole application in code, but not in the Manifest?

Question

I know how to set theme to whole application in manifest,but how to set theme to whole application programmatically ? I am trying this: getApplicationContext.se

Answer 1

In setTheme, the documentation says:

Note that this should be called before any views are instantiated in the Context (for example before calling setContentView(View) or inflate(int, ViewGroup)).

Have you taken care of that?
