Change color of the drop down arrow of Spinner in XML

As I wrote in my question, I want to change the color of the drop down arrow (the default arrow, not a custom arrow or something like that) of a Spinner in XML, but the problem is that I couldn't find anything to make reference to it from the XML.

Is it possible? If yes, how can I change the color?

Thanks in advance.

There are three ways to achieve that.

1. Through code:

In your xml, make sure your spinner has an id. Let's say we have a spinner with id "spinner".

In your code, add the following in your onCreate():

Spinner spinner = (Spinner) findViewById(R.id.spinner);
spinner.getBackground().setColorFilter(getResources().getColor(R.color.red), PorterDuff.Mode.SRC_ATOP);

where red is your defined color in colors.xml in the values folder.

2. Through xml:

For API 21+:

<Spinner
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:backgroundTint="@color/red" />

or if you use the support library, you can use:

<android.support.v7.widget.AppCompatSpinner
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:backgroundTint="@color/red" />

3. Through drawables:

You can use this online tool: http://android-holo-colors.com

This will generate custom drawables for any view you want with your preferred color. Make sure you select spinner, then download the resources.

I'm surprised noone had pointed it out, but you can just subclass Widget.AppCompat.Spinner and change backgroundTint

<style name="Spinner" parent="Widget.AppCompat.Spinner">
        <item name="backgroundTint">@color/spinnerTint</item>
</style>

and apply it to the Spinner

<Spinner
    style="@style/Spinner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:spinnerMode="dropdown" />

use backgroundTint attribute

<Spinner
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:backgroundTint="@color/white"
        />

if min_SDK < 21(Lollipop) you should use AppCompatSpinner

<android.support.v7.widget.AppCompatSpinner
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:backgroundTint="@color/white"
        />

If (API 21+) {

you can use directly android:backgroundTint="@color/color", inside your Spinner:

<Spinner
   android:id="@+id/spinner"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:backgroundTint="@color/color" />

} else {

create your own style:

<style name="spinner_style" parent="Widget.AppCompat.Spinner">
        <item name="backgroundTint">@color/color</item>
</style>

then into Spinner:

<Spinner
   android:id="@+id/spinner"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   style="@style/spinner_style"/>

}

Note: you can use the style method in all API's.

try this:

spinner_age.getBackground().setColorFilter(ContextCompat.getColor(this,
                R.color.spinner_icon), PorterDuff.Mode.SRC_ATOP);
