Question

I’ve passes by this tutorial:

Android: Creating and populating ListView items in XML

I want to initialize a ListView in the xml not the code.

my array.xml file:

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string-array name="anyArray">
        <item>one</item>
        <item>two</item>
        <item>three</item>
    </string-array>

</resources>

my activity_main.xml file:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ListView
        android:id="@+id/listView1"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:entries="@array/anyArray" >
    </ListView>

</RelativeLayout>

When I switch to the layout, I get this warning

Couldn't resolve resource @array/anyArray

and no items are displayed. How can I fix this problem?

Answer 1

Your resources’ names should only contain [a-z0-9._]. Rename your Array to all lower case characters.
