I'm on the 1.0 SDK and I'm having the exact same problem... I spent a
few hours on the forums & googling, but the only suggestion I can find
is to make sure you call setContentView(...) before you call
findViewById. I can't seem to get past this -- I can't lookup any of
my views from onCreate. Posting relevant portion of main activity --
am I doing anything stupid/wrong here?
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button btn = (Button)this.findViewById(R.id.btn_about); /*
RuntimeException here */
if(btn != null)
{
return; /* set a breakpoint here*/
}
}
Thanks
Sam
