Android Array List

Question

I am getting an error on this line:-"for(Item item:Items)" on "Items" keyword and the error is "Type mismatch: cannot convert from element type Object to Item". somebody Please help me out for this.

import java.util.ArrayList;

public class Model 
{
    public static ArrayList Items;

    public static void LoadModel()
    {
        Items=new ArrayList();
        Items.add(new Item(1, "taj.png", "Taj Mahal", "arrow.png"));
        Items.add(new Item(2, "agra_fort.png", "Agra Fort", "arrow.png"));
        Items.add(new Item(3, "chini _ka_rauza.png", "Chini ka Rauza", "arrow.png"));
        Items.add(new Item(4, "fatepur_sikri.png", "Fatepur Sikri", "arrow.png"));
        Items.add(new Item(5, "guru_ka_tal.png", "Guru Ka Tal", "arrow.png"));
        Items.add(new Item(6, "jamma_masjid.png", "Jamma Masjid", "arrow.png"));
        Items.add(new Item(7, "mankameshwar_temple.png", "Mankameshwar", "arrow.png"));
        Items.add(new Item(8, "mehtab_baug.png", "Mehtab Baug", "arrow.png"));
        Items.add(new Item(9, "musamman_burj.png", "Musamman Burj", "arrow.png"));
        Items.add(new Item(10, "panch_mahal.png", "Panch Mahal", "arrow.png"));


    }
    public static Item GetbyId(int id)
    {
        for(Item item:Items)
        {
            if(item.id==id)
            {
                return item;
            }
        }
        return null;
    }

}

Try to declare list this way : public static ArrayList<Item> Items; — Hareshkumar Chhelana

Why are you create custom holder class from item you can simply hold this type data using HashMap if you prefer. — Hareshkumar Chhelana

First initialize the ArrayList as

  ArrayList<Item> Items = new ArrayList<Item>();

It should be Items= new ArrayList<Item>(); Otherwise Java assumes the worst case of Object.

Oh, as @Aniruddha mentioned- you need the <Item> in the declaration as well.
