Question

I am looking for a guide as to how i can implement switch that would get values from a string array. Basically, i have a spinner with all the items as stated in my array, so i want to implement a switch so that whenever i click on an item, it will trigger an event, for example, going to another activity.

<string-array name="location1">

    <item>string a</item>
    <item>string a</item>
    <item>string b</item>
    <item>string c</item>
    <item>string d</item>

</string-array>

So, if i have a string array like this, how should I implement my switch statement?

Answer 1

If array is:

<string-array name="cars_array">
    <item>Audi</item>
    <item>Ferrari</item>
</string-array>

You can access them like this:

Resources res = getResources();
String[] cars = res.getStringArray(R.array.cars_array);

then you can access them individually as cars[0], cars[1] etc

If you want to access the same string resource as part of an array and individually as well, then you can do this:

<string name="audi">Audi</string>
<string name="ferrari">Ferrari</string>

<string-array name="cars_array">
    <item>@string/audi</item>
    <item>@string/ferrari</item>
</string-array>

Then you can simply say “@string/audi” to get it individually as well as you can use the array name “@string/cars” to use the string array as a whole.
