Android generate xml elements based on array

Question

In WPF we can define an array and bind it to our xml. Elements are then automatically generated based on the contents of this array.:

public partial class MainWindow : Window {
    public MainWindow() { 
        InitializeComponent(); 
        this.DataContext = this;
    } 

    ObservableCollection<int> sampleData = new ObservableCollection<int>();
    public ObservableCollection<int> SampleData {
        get {
            if (sampleData.Count <= 0) {
                sampleData.Add(1);
                sampleData.Add(2);
                sampleData.Add(3);
                sampleData.Add(4);
            }
            return sampleData;
        }
    }
}


<Window x:Class="Sandbox.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
    <Grid>
        <ListBox ItemsSource="{Binding Path=SampleData}"/>
    </Grid>
</Window>

Is something like this possible in android?

You can define an XML file, in res/values/strings.xml, to define your array member using:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="planets_array">
        <item>Mercury</item>
        <item>Venus</item>
        <item>Earth</item>
        <item>Mars</item>
    </string-array>
</resources>

More about array resource

Then receive using

getResources().getStringArray(R.array.planets_array);

But there is no

automatically generated based on the contents of this array

similar method in Android. To do it you will need to implement an ArrayAdapter.
