java - mapping text to buttons from within a method -

i'm in stages of developing android app, , i'm trying settext buttons within method. doing not in method fine, want call method on , over. when try create method this, "non-static method findviewbyid(int) cannot referenced static context" error.

eg: button button = (button) findviewbyid(r.id.button); button.settext(options[0]);

the findviewbyid red highlighted

remove

static

from functions. remove functions oncreate callback, don't belong there.

when you're invoking functions in oncreate, functions/methods cannot static
