 ArrayAdapter<String> adapter=new ArrayAdapter<String>(HotelActivity.this, android.R.layout.simple_list_item_1,Category);
        listView.setAdapter(adapter);

        listView.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View v, int position,
                    long id) {
                if(position>0){
                    Intent intent=new Intent(HotelActivity.this,NewList.class);
                    intent.putExtra("position", position);
                    startActivity(intent);
                }
            }
        });

新しいアクティビティを作成し、そのxmlファイルでlistviewを宣言します

NewListアクティビティ：

public class NewList extends Activity{
    ListView listView;
    int pos=0;
    ArrayAdapter<String> adapter;
    String[] Beverage={"PEPSI","COKE","LASSI","FALOODA","BUTTER MILK","GREEN TEA","BADAM MILK","MASALA CHAI" };
    String[] Breakfast={"SIRLOIN & EGG","CFS STEAK & EGG","T-BONE & EGG","TWO EGGS BREAKFAST","2EGG W/MEAT","BEL WAFFLE","BEL WAFFLE W/MEAT","BLUEBERRY CAKE","CAKES","FABULOUS FRENCH TST","MOONS","FRENCH TST"};
    String[] Lunch={" CRAB CAKE SANDWICH","TUSCAN GRILLED CHICKEN PANINI","SOUTHWEST TURKEY CLUB"," LOBSTER ROLL","TUNA MELT"," FRENCH DIP","YOUR OWN SANDWICH"};
    String[] Dinner={"DUBLIN BAY PRAWN","CRAB FROM BRITTANY","WHITE ASPARAGUS","BLEWIT MUSHROOM","JOHN DORY FISH","MONKFISH","VEAL SWEET BREAD","LAMB","PIGEON FRY"};
    String[] Desserts={"ECHOURGNAC CHEESE","HAZELNUT","GARIGUETTE STRAWBERRY","MOUSSE & ZEST","APRICOT","CHOCOLATE"};
    String[] Appetizers={"Greek Artichoke Spinach","Seafood Appetizers","Tapenade Flatbread","Cranberry Blue Cheese","Fig and Blue Cheese","Sun-Dried Tomato","Tropical Crab Rangoon"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mylist);


        listView=(ListView) findViewById(R.id.newlist);
        Bundle bundle=getIntent().getExtras();
        if(bundle!=null){
            pos=bundle.getInt("position");
        }

        if(pos==1){
            adapter=new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1,Beverage);
            listView.setAdapter(adapter);
        }
        else if(pos==2){
            adapter=new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1,Breakfast);
            listView.setAdapter(adapter);
        }
        else if(pos==3){
            adapter=new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1,Lunch);
            listView.setAdapter(adapter);
        }
        else if(pos==4){
            adapter=new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1,Dinner);
            listView.setAdapter(adapter);
        }
        else if(pos==5){
            adapter=new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1,Desserts);
            listView.setAdapter(adapter);
        }
        else if(pos==6){
            adapter=new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1,Appetizers);
            listView.setAdapter(adapter);
        }
    }

}

これがお役に立てば幸いです。
