Create a spinner using a double array

Question

I am trying to create a spinner which gets its values from a double array but i get the error: java.lang.Double[], required int, i have values such as 1.4 or 2.8 which is why i cant use an int array. My code is here below:

Double[] FULL = new Double[]{2.25,2.5,2.8};
adapter = ArrayAdapter.createFromResource(this,FULL,android.R.layout.simple_selectable_list_item);

I have tried converting my double array into an int array but that doesn't seem to work as well, i am relatively new to android so i may be doing the conversion wrong. Can i get some help?

Int indiacate the resources in Android . Default array adapter only takes String array . So just use quotes for double values .and use ArrayAdapter defined String Array — SpiritCrusher

@ADM I need to get the values after that as a number to add to something, will this still work? — Mohammedis271

You just accepted the answer below. Which is same what i had suggested previously. And to get Value you need to parse it with Double.parseDouble(value). — SpiritCrusher

You are using the ArrayAdapter.createFromResource() wrong. Please, refer to the documentation.

To fix your problem, add your FULL array to an array in values > string.xml

<array name="spinner_val">
    <item>"2.0"</item>
    <item>"3.0"</item>
    <item>"4.0"</item>
    ...
 </array>

Then retrieve them as strings since you are going to display them in a text.

ArrayAdapter.createFromResource (this, 
                getContext().getResources().getStringArray(R.array.spinner_val), 
                R.layout.simple_selectable_list_item);
