Java 原因：android.database.sqlite.SQLiteException:没有这样的表：food（代码1 sqlite_错误）：，编译时：按id asc 1从食品订单中选择*

当我编译程序时，我在Logcat中得到了这个错误

根据Logcat，这是导致错误的两个地方

一,

    db=openOrCreateDatabase("Restaurants_DB", Context.MODE_PRIVATE, null);
    locations = loadLocationData();
    addListenerOnButton();
    initializeUI();

二,

以下是日志：

Activity

menudrinksavity

在

AddDrinkActivity

之前被调用，所以此时不创建表。我建议在

应用程序

类中初始化数据库。该类在任何活动之前调用，所以在开始使用数据库和表之前，将初始化数据库和创建表

public class AndroidApplication extends Application {
    @Override
    public void onCreate() {
        // initialize database here
    }
}

不要忘记在清单中注册

应用程序
类，如下所示：

<application
    ...
    android:name="com.example.AndroidApplication">
    ...
</application>


...
改进的代码格式
