Answer 3

You can get like

View layout = inflater.inflate(R.layout.activity_register,
            (ViewGroup) youractivity.this.findViewById(R.id.popup_element));

btnReg = (Button) layout.findViewById(R.id.btnReg);
inputName = (EditText) layout.findViewById(R.id.name);
inputDOB = (DatePicker) layout.findViewById(R.id.dob);

It's becoz your all the elements coming from inflated layout view and you need to pass context to get your popup_element layout as ViewGroup.
