Android: Custom triangle icon in spinner using android eclipse

how to customize the icon in the right side of the spinner. As you can see in the image below inside of the red circle there is a black circle the data inside of that spinner came from database. Is there a way to remove it? if none, how to change it?
For the code, I just add this in my styles.xml and then that black circles appeared also.
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:spinnerItemStyle">#style/SpinnerItem</item>
<item name="android:spinnerDropDownItemStyle">#style/SpinnerItem.DropDownItem</item>
</style>
<style name="SpinnerItem" parent="#android:style/Widget.TextView.SpinnerItem">
<item name="android:textColor">#909090</item>
</style>
<style name="SpinnerItem.DropDownItem" parent="#android:style/Widget.DropDownItem.Spinner">
<item name="android:textColor">#909090</item>
</style>
Thanks.

I already have answer.
instead of this code
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:spinnerItemStyle">#style/SpinnerItem</item>
<item name="android:spinnerDropDownItemStyle">#style/SpinnerItem.DropDownItem</item>
</style>
<style name="SpinnerItem" parent="#android:style/Widget.TextView.SpinnerItem">
<item name="android:textColor">#909090</item>
</style>
<style name="SpinnerItem.DropDownItem" parent="#android:style/Widget.DropDownItem.Spinner">
<item name="android:textColor">#909090</item>
</style>
I made it like this
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:textColor">#909090</item>

Android styles: how to change colors in styles.xml

I want to change some colors of android UI elements. But I would prefer to set a default tint color, which applies to all UI elements. I am not sure if this is possible.
If not, I want to set the "tint"-color of some UI elements, as shown below. Can anybody enlighten me?
EDIT
Based on what Entreco suggested:
My styles.xml:
<resources>
<!-- Base application theme. -->
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="android:textColorPrimary">#color/brown</item>
<item name="android:textColorSecondary">#color/brown</item>
<item name="android:textColorTertiary">#color/brown</item>
<item name="android:textColorPrimaryInverse">#color/brown</item>
<item name="android:textColorSecondaryInverse">#color/brown</item>
<item name="android:textColorTertiaryInverse">#color/brown</item>
<item name="colorPrimary">#color/blue</item>
<item name="colorPrimaryDark">#color/blue</item>
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
<!-- style for the action bar backgrounds -->
<style name="MyActionBar" parent="#style/Widget.AppCompat.Light.ActionBar">
<item name="android:titleTextStyle">#style/MyTheme.ActionBar.TitleTextStyle</item>
<item name="android:subtitleTextStyle">#style/MyTheme.ActionBar.TitleTextStyle</item>
<item name="android:background">#color/brown</item>
<item name="titleTextStyle">#style/MyTheme.ActionBar.TitleTextStyle</item>
<item name="subtitleTextStyle">#style/MyTheme.ActionBar.TitleTextStyle</item>
<item name="background">#color/brown</item>
</style>
<style name="MyTheme.ActionBar.TitleTextStyle" parent="#android:style/TextAppearance">
<item name="android:textColor">#color/brown_light</item>
<item name="android:textSize">24sp</item>
</style>
</resources>
And my values-v21/styles.xml:
<resources>
<style name="AppTheme" parent="AppTheme.Base">
<item name="android:colorPrimary">#color/blue</item>
<item name="android:colorPrimaryDark">#color/blue</item>
<!-- <item name="android:colorAccent">#color/white</item> -->
</style>
</resources>
And in my Manifest:
<application android:theme="#style/AppTheme.Base" >
...
</application>
But the primary color is still the same...???

Starting from Lollipop this is straight-forward thanks to the colorPrimary attribute:
file values/styles.xml:
<!-- Base application theme. -->
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/primary</item>
<item name="colorPrimaryDark">#color/primary_dark</item>
</style>
file values-v21/styles.xml:
<style name="AppTheme" parent="AppTheme.Base">
<item name="android:colorPrimary">#color/primary</item>
<item name="android:colorPrimaryDark">#color/primary_dark</item>
<item name="android:colorAccent">#color/white</item>
</style>
Basically, you can define a color pallete for your app, and I believe for your case your want to set the colorPrimary (unverified).

Android's Material Design of Toolbar / SupportActionBar

I'm experimenting with the news themes tonight and I'm wondering if anyone knows these fix to this issue.
This appears on the stock Toolbar and even, as seen below, when referring to custom layout file.
It's relatively minor but my OCD eyes go right to it so maybe someone can help. Thanks :)

UPDATE: Inheriting from the correct theme and declaring attributes in pairs (with and without the android: prefix) was the fix!
<!-- Base app theme. -->
<style name="AppTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
<!-- ActionBar styles. -->
<style name="MyActionBar" parent="Widget.AppCompat.ActionBar">
<item name="android:titleTextStyle">#style/MyActionBarTitleText</item>
<item name="titleTextStyle">#style/MyActionBarTitleText</item>
<item name="android:subtitleTextStyle">#style/MyActionBarSubTitleText</item>
<item name="subtitleTextStyle">#style/MyActionBarSubTitleText</item>
<item name="android:background">#color/blue</item>
<item name="background">#color/blue</item>
</style>
<style name="MyActionBarTitleText" parent="#style/TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textColor">#color/white</item>
</style>
<style name="MyActionBarSubTitleText" parent="#style/TextAppearance.AppCompat.Widget.ActionBar.Subtitle">
<item name="android:textColor">#color/white</item>
<item name="android:textSize">#dimen/subtitle</item>
</style>

If es0329's answer doesn't work for you, try to replace titleTextStyle by titleTextAppearance. It is working for me:
<style name="MyActionBar" parent="Widget.AppCompat.ActionBar">
<item name="android:titleTextAppearance">#style/MyActionBarTitleText</item>
<item name="titleTextAppearance">#style/MyActionBarTitleText</item>
<item name="android:subtitleTextAppearance">#style/MyActionBarSubTitleText</item>
<item name="subtitleTextAppearance">#style/MyActionBarSubTitleText</item>
<item name="android:background">#color/blue</item>
<item name="background">#color/blue</item>
</style>

The actionBarItemBackground theme attribute will allow you to change the action item selector.
If you're using it with ActionBarSherlock or ActionBarCompat, be sure to provide an entry with and without the android: prefix.
In your style you can use below lines:
<item name="android:actionBarItemBackground">#drawable/my_drawable</item>
<item name="actionBarItemBackground">#drawable/my_drawable</item>
Hope it will help you..

Change ActionBar OverflowMenu Background color

Ive added a lot of properties to change to background color of the overflow menu, none seem to work.
Here are a few links i've refered (other than SO questions):

<!-- style the items within the overflow menu -->
<style name="MyDropDownListView" parent="android:style/Widget.Holo.ListView.DropDown">
<item name="android:listSelector">#28bda9</item>
</style>
<!-- style the list navigation -->
<style name="MyDropDownNav" parent="android:style/Widget.Holo.Light.Spinner">
<item name="android:background">#28bda9</item>
<item name="android:popupBackground">#28bda9</item>
<item name="android:dropDownSelector">#28bda9</item>
</style>
</resources>
Edit: I have changed the code to match the solution. This was the error:
<style name="MyPopupMenu" parent="#android:style/Widget.Holo.ListPopupWindow">
<item name="android:popupBackground">**#28bda9**</item>
</style>

You're on the right track, but the popupBackground is not merely a color.
You have to change the drawable.
Below is the default drawable for Holo Light (usually called menu_dropdown_panel).
Change the color using your favorite image editor, and put it your drawable-x folder.
The needed style will be as follows:
<style name="AppTheme" parent="AppBaseTheme">
...
<item name="android:popupMenuStyle">#style/MyPopupMenu</item>
</style>
<style name="MyPopupMenu" parent="#android:style/Widget.Holo.ListPopupWindow">
<item name="android:popupBackground">#drawable/menu_dropdown_panel</item>
</style>
