我将数据传递给ListView以显示一些餐厅名称。现在，当点击某个项目时，我想开始另一项活动以显示更多餐馆数据。我不知道如何去做。我是否应该通过意向对象将所有餐馆数据传递给捆绑销售商？或者我应该通过餐厅ID并从其他活动中获取数据？在那种情况下，我如何从其他活动访问我的restaurantList？无论如何，我怎样才能从我点击的餐厅（视图只包含名称）获取数据？如何通过Android中的任何活动访问未存储在数据库中的数据？
任何帮助，指针欢迎！
ListView lv= (ListView)findViewById(R.id.listview);
lv.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,restaurantList.getRestaurantNames()));
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent i = new Intent(Atable.this, RestaurantEdit.class);
Bundle b = new Bundle();
//b.putInt("id", ?);
startActivityForResult(i, ACTIVITY_EDIT);
}
});

this.restaurants = restaurants;
}
public List<String> getRestaurantNames() {
List<String> restaurantNames = new ArrayList<String>();
for (int i=0; i<this.restaurants.size(); i++) {
restaurantNames.add(this.restaurants.get(i).getName());
}
return restaurantNames;
}
