Android Question

Is there a super simple List / ListAdapter example out there for android

I have a web service that returns a super simple list of objects

MyObject[] data = webServiceCall();

MyObject has 1 field i want to display,


How can i turn this into an activity that lists just the name of these objects in a scrollable
on Android. I am getting really confused with Cursors and am not sure if I need Cursors and I"m not sure what kind of adapter to implement (

So i guess i'm looking for three things,

the activity, the adapter and the

Just trying to figure this android stuff out, definitely a noob here

Answer Source

so i think i figured it out with a little inspiration from RobGThai's answer, i'm posting the code for anyone else to see, i guess i didn't really use a custom adapter

This is the super simple example that got me started, so once i had this, I made sure my "MyObject" had a toString() method on it to show properly in the list and i passed the MyObject[] array into the "new ArrayAdapter" constructor instead of listItems

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

public class FooList extends ListActivity {
    String[] listItems = {"item 1", "item 2 ", "list", "android", "item 3", "foobar", "bar", }; 
     public void onCreate(Bundle savedInstanceState) {
         setListAdapter(new ArrayAdapter(this,  android.R.layout.simple_list_item_1, listItems));


the layout xml i used (temp.xml)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""
    android:orientation="vertical" android:layout_width="fill_parent"
    <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="Empty set" />
