Help with listView in Android

I'm just starting with Android and can't find how to display a list in my activity. The activity and the layout main.xml are shown below. How can I display the country array in the ListView 'list' of my layout?

thank you

public class Atable extends ListActivity {      


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

    String[] COUNTRIES = new String[] { "Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra"};
    setListAdapter(new ArrayAdapter<String>(this, R.layout.main, COUNTRIES)); //I tried this but it does not work


    }

main.xml

    <LinearLayout android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
        <TextView android:layout_width="wrap_content"
            android:layout_height="wrap_content" 
            android:text="@string/search" />
        <EditText android:id="@+id/search" 
          android:layout_width="wrap_content"
            android:layout_height="wrap_content" 
            android:layout_weight="1"/>
    </LinearLayout>

    <LinearLayout android:orientation="vertical"
      android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <ListView android:id="@id/android:list"
              android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>

Here is a good working example

I think the easiest way is to override toString method in your restaurant class and use an ArrayAdapter< Restaurant> as your list content and then set it with setAdapter

Replace R.layout.main with android.R.layout.simple_list_item_1

http://developer.android.com/reference/android/app/ListActivity.html

I guess this is what you where trying to do:

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class LayoutTest extends ListActivity {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        String[] COUNTRIES = new String[] {"Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra"};
        setListAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, COUNTRIES)); //I tried this but it does not work
    }
}

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <LinearLayout android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">

        <TextView android:layout_width="wrap_content"
            android:layout_height="wrap_content" 
            android:text="@string/search"/>
        <EditText android:id="@+id/search" 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" 
            android:layout_weight="1"/>
    </LinearLayout>

    <LinearLayout android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">

        <ListView android:id="@android:id/list"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"/>
        <TextView android:id="@android:id/empty"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/noresults"/>
    </LinearLayout>
</LinearLayout>
