【问题描述】：
您好，感谢您阅读本文！请帮帮我。
我正在尝试创建一个餐厅应用程序，该应用程序在菜单中显示 3 个按钮，然后单击显示食物列表的食物按钮，然后客户可以选择他们想要订购的食物，然后将订单发回第一页.我读了很多文章，有人说使用 listview.setItemsCanFocus(true) 但我在理解它来实现它时遇到了问题。有人说getView中的按钮监听器但是当我实现我的程序时只是挂起。请帮我。谢谢。
我的菜单：
这是我的食物（第二）页
我遇到了问题：
将所选数据（食品订单）数组从 food.class 传回我的主类，即 restaurant.class
在列表中添加按钮后，食物不可点击（整行食物）。
点击图片放大及其他地方（图片除外）
我的主要课程（餐厅）
public class SesameRestaurant extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void foodMenu(View v){
startActivity(new Intent(SesameRestaurant.this,Food.class));
//setContentView(R.layout.foods);
}
public void drinkMenu(View v){startActivity(new Intent(SesameRestaurant.this,Drink.class));}
public void billMenu(View v){}
}
