protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        createIntent();

    }

    public Intent createIntent() 

     {

}

Am i calling the method right.

A new Activity is called with:

startActivity(new Intent(currentActivity.this, nextActivity.class));

Then in your new Activities onCreate(Bundle savedInstance) method you can call setContentView(Layout layout); to set the new Layout.

So if you want to change the Activity when clicking on a Button you have to do the following:

button.setOnClickListener(new View.OnClickListener(){

            public void onClick(View v){
                startActivity(new Intent(currentActivity.this, nextActivity.class));
            }

        });

You are currently only changing the layout of the current Activity when clicking the button and not changing to another Activity.

I hope I understood you correctly. If not then provide me with some more code so I can try to understand what you want to do.
