[android] Android: Create spinner programmatically from array

I'm all new to Android and I'm trying to create a spinner programmatically and feeding it with data from an array, but Eclipse gives me a warning that I can't handle.

Here's what I got:

This ArrayList holds the elements that should be in the spinner (gets filled from a file later on):

ArrayList<String> spinnerArray = new ArrayList<String>();

This is code I found on a site which should create the spinner:

Spinner spinner = new Spinner(this);
ArrayAdapter spinnerArrayAdapter = new ArrayAdapter(this,
                android.R.layout.simple_spinner_dropdown_item,
                spinnerArray);
spinner.setAdapter(spinnerArrayAdapter);

Now the second line (ArrayAdapter...) gives me a warning in Eclipse saying "ArrayAdapter is a raw type... References to generic type ArrayAdapter<T> should be parameterized", I have no idea how to fix this (or what that means in the first place :) ).

It's just a warning and the App seems to run alright, but I'd still like to understand what's wrong and fix it. Any hint is appreciated.

In Kotlin language you can do it in this way:

val values = arrayOf(
    "cat",
    "dog",
    "chicken"
)

ArrayAdapter(
    this,
    android.R.layout.simple_spinner_item,
    values
).also {
    it.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)
    spinner.adapter = it
}

This worked for me with a string-array named shoes loaded from the projects resources:

Spinner              spinnerCountShoes = (Spinner)findViewById(R.id.spinner_countshoes);
ArrayAdapter<String> spinnerCountShoesArrayAdapter = new ArrayAdapter<String>(
                     this,
                     android.R.layout.simple_spinner_dropdown_item, 
                     getResources().getStringArray(R.array.shoes));
spinnerCountShoes.setAdapter(spinnerCountShoesArrayAdapter);

This is my resource file (res/values/arrays.xml) with the string-array named shoes:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="shoes">
        <item>0</item>
        <item>5</item>
        <item>10</item>
        <item>100</item>
        <item>1000</item>
        <item>10000</item>
    </string-array>
</resources>

With this method it's easier to make it multilingual (if necessary).

this work for me:-

String[] array = {"A", "B", "C"};
String abc = "";


Spinner spinner = new Spinner(getContext());
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(getContext(), android.R.layout.simple_spinner_item, array); //selected item will look like a spinner set from XML
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(spinnerArrayAdapter);

I am using a Fragment.

In the same way with Array

// Array of choices
String colors[] = {"Red","Blue","White","Yellow","Black", "Green","Purple","Orange","Grey"};

// Selection of the spinner
Spinner spinner = (Spinner) findViewById(R.id.myspinner);

// Application of the Array to the Spinner
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this,   android.R.layout.simple_spinner_item, colors);
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); // The drop down view
spinner.setAdapter(spinnerArrayAdapter);

This actually worked for me

    Spinner spinner = new Spinner(this);
    ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(
            this, android.R.layout.simple_spinner_item, spinnerArray);
    spinnerArrayAdapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item );

    spinner = (Spinner) findViewById( R.id.spinner );
    spinner.setAdapter(spinnerArrayAdapter);
