findViewById in a non-activity class?

Guys, i'am stuck on this for like a week... So i want to call a findViewById in a non-activity class.

EXP: I got MainActivity and a AddCustomer activity.By pressing a button in a AddCustomer activity i want to make new TextView in a LinearLayout in MainActivity.When i do that now i'm getting nullExeption on this line: mLinearLayout = (LinearLayout)findViewById(R.id.customerLinearLayout);

customerLinearLayout is a layout from MainActivity so i'am getting a null pointer exception because of this.How can I resolve this issue?
