Question

I have this:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    LinearLayout layout = (LinearLayout) View.inflate(this, R.layout.main, null);
    setContentView(layout);
    s = (Spinner) findViewById(R.id.spinner1);

It throws a ClassCastException why is it?
If I do setContentView(R.layout.main) everything goes well. But i need to have the layout in a variable because I need it to use an advertsiment library. Is there a a way to inflate the XML and have the layout in an variable?

Thanks

Which line is throwing the ClassCastException?

Also you can use setContentView(R.layout.main); then still use a normal find view by id call to get a reference to your root layout.

LinearLayout layout = (LinearLayout)findViewById(R.id.yourParentId);

as long as this comes after you’ve called setContentView() you should get returned a reference to your layout object that you can use however you wish.
