Question

I thought I had this figured out, but I obviously don’t.

In an Android App I’m making a spinner will change it’s contents based on a previous spinner’s selection. The listener works and the second spinner is changing, however there is a third spinner that is not getting its contents.

What I would like to achieve is something along the lines of:

if (spinner1.selection == "Acura") {
spinner2 = "Acura";
}

The string-arrays that I’m calling are integers in the R.java file so for Acura it would be: R.array.Acura

So my question would be:

How can I call the integer R.array.* dynamically based on a string.

I hope my question makes sense.

Cheers

Use the getIdentifier() method on your activity to look up the resource ID.

For example:

spinner2 = "Acura";
int arrayResourceId = getResources().getIdentifier(spinner2, "array", getPackageName());
