Android spinner if statement

Hi i need help constructing an if statement that will limit the values in a proceeding spinner based on whether a certain value is selected in the first spinner.

                ArrayAdapter<String> ItemTypeAdapter =new ArrayAdapter<String> (
                        this,R.layout.support_simple_spinner_dropdown_item, ItemTypes );
                //TODO If Item Types = "Tops" then use Top Sizes else use WaistSizes else ShoeSizes etc
                ArrayAdapter<String> ItemTopSizeAdapter = new ArrayAdapter<String>(
                        this,R.layout.support_simple_spinner_dropdown_item, TopSizes);
                ArrayAdapter<String> ItemWaistSizeAdapter = new ArrayAdapter<String>(
                        this,R.layout.support_simple_spinner_dropdown_item, WaistSizes);
                ArrayAdapter<String> ItemShoeSizeAdapter = new ArrayAdapter<String>(
                        this,R.layout.support_simple_spinner_dropdown_item, ShoeSizes);
