Solution in XML: Referencing a Single Item from a String Array 🔍🆔💡
Although the official Android developer reference may not explicitly mention how to reference a string from an array resource in XML, fear not! We have a neat workaround for you. 😉
To reference a single item from a string array in XML, you can use the following syntax:
@array/array_name[index]Replace array_name with the name you gave to your string array in arrays.xml. Use [index] to indicate the position of the string you want to reference.
For example, let's say you named your string array menu_titles and want to use the third item in your preferences.xml layout file. Here's how you can do it:
android:title="@array/menu_titles[2]"Remember, arrays in programming languages are zero-indexed, so the third item would be at index 2. 😉
