XML OnClick attribute Does no Work on setContent Change

Question

I'm trying to implement multiple layouts in one activity using set content multiple times and initializing all widgets again with it, so far i'm sucessfull, but i'm stuck at one point.

1. setContentView(R.layout.layout1) --> initWidgets1(); --> btn1.setOnClickListner() -->Works

2. setContentView(R.layout.layout2) --> initWidgets2(); --> btn2.setOnClickListner() -->Works

But

handleClick2(View v)
{
Switch (v.getId())
{-------------
---------
Multiple click handles
-----
---
}

Similarly.
handleClick1(View v)
{
Switch (v.getId())
{
-----------
---------
Multiple click handles
-----
---
}

this method does not work either for any layouts.

while btn.setOnClickListner() works but it will take huge memory for huge lists, latter would be easy if it works.

code:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    setContentView(R.layout.activity_user);
    initCurrUserWidgets();      
    setAdapter();   
    setCurrUserClickListners();
}

private void initNewUsrWidgets() {
    // TODO Auto-generated method stub
           cancel_new_user          =   (TextView)findViewById(R.new_user.cancel_TV);
           name_new_user            =   (TextView)findViewById(R.new_user.name_TV);
           username_new_user        =   (TextView)findViewById(R.new_user.username_TV);
           password_new_user        =   (TextView)findViewById(R.new_user.password_TV);
           phone_new_user           =   (TextView)findViewById(R.new_user.phone_TV);
           email_new_user           =   (TextView)findViewById(R.new_user.email_TV);
           role_new_user            =   (TextView)findViewById(R.new_user.role_TV);
           window_group_new_user    =   (TextView)findViewById(R.new_user.window_group_TV);
           room_office_new_user     =   (TextView)findViewById(R.new_user.room_office_TV);


    //New User's input Dialog
            user_input_Dialog   = new Dialog(UserActivity.this);
            user_input_Dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            user_input_Dialog.setContentView(R.layout.userdialog);
            user_input_Dialog.setCanceledOnTouchOutside(false);
            doneBtn_userDialog = (Button) user_input_Dialog.findViewById(R.userBox.done_Button);

Try using multiple Activities or Fragments instead. Most people do not do what you are trying to do.
