Question

I have a ListView and it should be populated with ArrayList of objects.

ArrayList<BrowserClass> playListArr = new ArrayList<BrowserClass>();

and here is BrowserClass:

public class BrowserClass{
    String musicName = null;
    int musicId = 0;

    BrowserClass(String Name, int Id)
    {
        musicName = Name;
        musicId = Id;
    }

    public String getName()
    {
        return musicName;
    }

    public int getId()
    {
        return musicId;
    }

}

In order to populate ListView I am using following code:

ArrayAdapter<BrowserClass> plAdapter = new ArrayAdapter<BrowserClass>(this, android.R.layout.simple_list_item_1, playListArr);
myListView.setAdapter(plAdapter);

But the listView is showing some garbage value. I need to display only the names(getname() in browser class). I can achieve this using Custom Listview, BaseAdapter. But i want to implement it without using BaseAdapter.

Answer 1

like this :

Product.java

public class Product {
private int id;
private String name;
private double price;

public Product(){
    super();
}

public Product(int id, String name, double price) {
    super();
    this.id = id;
    this.name = name;
    this.price = price;
}

@Override
public String toString() {
    return this.id + ". " + this.name + " [$" + this.price + "]";
}
}

MainActivity

public class MainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ListView listView1 = (ListView) findViewById(R.id.listView1);

    Product[] items = { 
        new Product(1, "Milk", 21.50), 
        new Product(2, "Butter", 15.99), 
        new Product(3, "Yogurt", 14.90), 
        new Product(4, "Toothpaste", 7.99), 
        new Product(5, "Ice Cream", 10.00), 
    };

    ArrayAdapter<Product> adapter = new ArrayAdapter<Product>(this,
                android.R.layout.simple_list_item_1, items);

    listView1.setAdapter(adapter);
}
}
