How to change the dialog's button colors for a Material Date picker

I'm using Material components to create a DatePicker. From what I understand, colorPrimary is used to determine the color of the section at the top of the dialog, as well as the colors for the text on the buttons, specifically CANCEL and OK.
Going through the documentation, I can't seem to find a way to change just the color of the buttons at the bottom ? Is it possible to do that ?
current code:
<style name="ThemeOverlay.App.DatePicker" parent="#style/ThemeOverlay.MaterialComponents.MaterialCalendar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorOnPrimary">#android:color/white</item>
<item name="shapeAppearanceSmallComponent">#style/ShapeAppearance.App.SmallComponent</item>
<item name="shapeAppearanceMediumComponent">#style/ShapeAppearance.App.MediumComponent
</item>
<item name="materialCalendarHeaderTitle">#style/MyHeaderTitle</item>
<item name="colorOnPrimarySurface">#android:color/white</item>
</style>
<style name="MyHeaderTitle" parent="Widget.MaterialComponents.MaterialCalendar.HeaderTitle">
<item name="android:textColor">#android:color/white</item>
</style>
<style name="ThemeMaterialCalendarTextButton" parent="Widget.MaterialComponents.Button.TextButton.Dialog.Flush">
<item name="android:textColor">#android:color/white</item>
<item name="iconTint">#android:color/white</item>
</style>
<style name="ShapeAppearance.App.SmallComponent" parent="ShapeAppearance.MaterialComponents.SmallComponent">
<item name="android:textSize">24sp</item>
<item name="cornerSize">16dp</item>
</style>
<style name="ShapeAppearance.App.MediumComponent" parent="ShapeAppearance.MaterialComponents.MediumComponent">
<item name="android:textSize">30sp</item>
<item name="cornerSize">16dp</item>
</style>

You can use:
builder.setTheme(R.style.MaterialCalendarTheme)
and then define:
<style name="MaterialCalendarTheme" parent="ThemeOverlay.MaterialComponents.MaterialCalendar">
<!-- Buttons -->
<item name="buttonBarPositiveButtonStyle">#style/TextButton</item>
<item name="buttonBarNegativeButtonStyle">#style/TextButton</item>
</style>
<style name="TextButton" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">#color/...</item>
<item name="backgroundTint">#color/...</item>
</style>

How to set text and/or background color of Cut Copy Paste

I am using a custom Dark Theme in my app. Everything is doing okay, except for the Cut Copy Paste dialog that appears as a solid black square.
Surely there is a style that determines that, but I can't find it, or an answer that addresses this directly. Min API is 16.
<style name="DarkTheme" parent="AppTheme.NoActionBar">
<item name="colorPrimary">#color/blackBackground</item>
<item name="colorPrimaryDark">#color/blackBackground</item>
<item name="colorAccent">#color/yellow</item>
<item name="android:textColor">#color/whiteText</item>
<item name="android:background">#color/blackBackground</item>
<item name="buttonStyle">#style/darkButtonStyle</item>
<item name="spinnerStyle">#style/darkSpinnerStyle</item>
</style>
<style name="darkButtonStyle" parent="#android:style/Widget.Button">
<item name="android:layout_width">fill_parent</item>
<item name="android:textColor">#color/whiteText</item>
<item name="android:textSize">16sp</item>
<item name="android:padding">10dp</item>
<item name="android:textStyle">bold</item>
<item name="android:background">#color/darkBackground</item>
<item name="android:gravity">center</item>
<item name="android:textAllCaps">true</item>
</style>
<style name="darkSpinnerStyle" parent="Widget.AppCompat.Spinner">
<item name="android:background">#color/blackBackground</item>
<item name="android:paddingTop">0dp</item>
<item name="android:layout_marginStart">1dp</item>
<item name="android:layout_marginLeft">1dp</item>
<item name="android:layout_width">0dp</item>
<item name="android:layout_height">0dp</item>
</style>

I was having the same issue when regarding to MaterialAlertDialog. I was able to fix it using backgroundTint instead of background in styles. This is how:
Before
<style name="materialAlertDialog" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="android:background">#color/colorPrimaryDark</item>
<item name="materialAlertDialogTitleTextStyle">#style/TitleTextStyle</item>
<item name="materialAlertDialogBodyTextStyle">#style/BodyTextStyle</item>
<item name="buttonBarPositiveButtonStyle">#style/PositiveButtonStyle</item>
<item name="buttonBarNegativeButtonStyle">#style/NegativeButtonStyle</item>
</style>
This will be enough to repropduce the error that you are saying... So what i did was changing background for backgroundTint...
After
<style name="materialAlertDialog" parent="ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="android:backgroundTint">#color/colorPrimaryDark</item>
<item name="materialAlertDialogTitleTextStyle">#style/TitleTextStyle</item>
<item name="materialAlertDialogBodyTextStyle">#style/BodyTextStyle</item>
<item name="buttonBarPositiveButtonStyle">#style/PositiveButtonStyle</item>
<item name="buttonBarNegativeButtonStyle">#style/NegativeButtonStyle</item>
</style>
It seems like when you set a background and the dialog is created, the toolbar of copy/paste menu was changing his background in some weird way that i cant explain.
So this is not the exact answer for your problem but it may help you.
Note: Try removing background attr of your style. I have a dark theme and there is no need to use it. Just simple use <style name="AppTheme" parent="Theme.MaterialComponents.DayNight"> instead of <style name="DarkTheme" parent="AppTheme.NoActionBar">.

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.

Change generated action bar theme from Android Asset Studio

I have used Android Asset Studio to generate action bar style, however i woul like to do some changes, which I was unable to do in Studio, so I edited generated theme but lot of things was just ignored, and I just can't figure out how things work.
There is example:
`
<style name="Theme.Myactionbar" parent="#style/Theme.AppCompat.Light">
<item name="actionBarItemBackground">#drawable/selectable_background_myactionbar</item>
<item name="popupMenuStyle">#style/PopupMenu.Myactionbar</item>
<item name="dropDownListViewStyle">#style/DropDownListView.Myactionbar</item>
<item name="actionBarTabStyle">#style/ActionBarTabStyle.Myactionbar</item>
<item name="actionDropDownStyle">#style/DropDownNav.Myactionbar</item>
<item name="actionBarStyle">#style/ActionBar.Solid.Myactionbar</item>
<item name="actionModeBackground">#drawable/cab_background_top_myactionbar</item>
<item name="actionModeSplitBackground">#drawable/cab_background_bottom_myactionbar</item>
<item name="actionModeCloseButtonStyle">#style/ActionButton.CloseMode.Myactionbar</item>
</style>
<style name="ActionBar.Solid.Myactionbar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid">
<item name="background">#drawable/ab_solid_myactionbar</item> //THIS IS GREEN
<item name="backgroundStacked">#drawable/ab_solid_myactionbar</item>//THIS IS GREEN
<item name="backgroundSplit">#drawable/ab_bottom_solid_myactionbar</item>//THIS IS GREEN
<item name="progressBarStyle">#style/ProgressBar.Myactionbar</item>
</style>
<style name="ActionBar.Transparent.Myactionbar" parent="#style/Widget.AppCompat.Light.ActionBar">
<item name="background">#drawable/ab_transparent_myactionbar</item>
<item name="progressBarStyle">#style/ProgressBar.Myactionbar</item>
</style>
<style name="PopupMenu.Myactionbar" parent="#style/Widget.AppCompat.Light.PopupMenu">
<item name="android:popupBackground">#drawable/menu_dropdown_panel_example </item>
</style>
<style name="DropDownListView.Myactionbar" parent="#style/Widget.AppCompat.Light.ListView.DropDown">
<item name="android:listSelector">#drawable/selectable_background_myactionbar</item>
</style>
<style name="ActionBarTabStyle.Myactionbar" parent="#style/Widget.AppCompat.Light.ActionBar.TabView">
<item name="android:background">#drawable/tab_indicator_ab_myactionbar</item>
</style>
<style name="DropDownNav.Myactionbar" parent="#style/Widget.AppCompat.Light.Spinner.DropDown.ActionBar">
<item name="android:background">#drawable/spinner_background_ab_myactionbar</item>
<item name="android:popupBackground">#drawable/menu_dropdown_panel_myactionbar</item>
<item name="android:dropDownSelector">#drawable/selectable_background_myactionbar</item>
</style>
<style name="ProgressBar.Myactionbar" parent="#style/Widget.AppCompat.ProgressBar.Horizontal">
<item name="android:progressDrawable">#drawable/progress_horizontal_myactionbar</item>
</style>
<style name="ActionButton.CloseMode.Myactionbar" parent="#style/Widget.AppCompat.Light.ActionButton.CloseMode">
<item name="android:background">#drawable/btn_cab_done_myactionbar</item>
</style>
<!-- this style is only referenced in a Light.DarkActionBar based theme -->
<style name="Theme.Myactionbar.Widget" parent="#style/Theme.AppCompat">
<item name="popupMenuStyle">#style/PopupMenu.Myactionbar</item>
<item name="dropDownListViewStyle">#style/DropDownListView.Myactionbar</item>
</style>
Everything was like in generator, but then i tried the simplest change, that is the color, so I edited style name=ActionBar.Solid.Myactionbar and put there som other drawables from other generated style.
It looked like this :
<style name="Theme.Myactionbar" parent="#style/Theme.AppCompat.Light">
<item name="actionBarItemBackground">#drawable/selectable_background_myactionbar</item>
<item name="popupMenuStyle">#style/PopupMenu.Myactionbar</item>
<item name="dropDownListViewStyle">#style/DropDownListView.Myactionbar</item>
<item name="actionBarTabStyle">#style/ActionBarTabStyle.Myactionbar</item>
<item name="actionDropDownStyle">#style/DropDownNav.Myactionbar</item>
<item name="actionBarStyle">#style/ActionBar.Solid.Myactionbar</item>
<item name="actionModeBackground">#drawable/cab_background_top_myactionbar</item>
<item name="actionModeSplitBackground">#drawable/cab_background_bottom_myactionbar</item>
<item name="actionModeCloseButtonStyle">#style/ActionButton.CloseMode.Myactionbar</item>
</style>
<style name="ActionBar.Solid.Myactionbar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid">
<item name="background">#drawable/ab_solid_example</item>
<item name="backgroundStacked">#drawable/ab_stacked_solid_example</item>
<item name="backgroundSplit">#drawable/ab_bottom_solid_myactionbar</item>
<item name="progressBarStyle">#style/ProgressBar.Myactionbar</item>
</style>
but nothing happend, and changed drawables supposed to be gray. I was wandering if anybody did this before and why this isnt working? Thank you

Ok I figured it out, there is values-v14 folder for styles for api level 14 and above, so you have to change these values too.

How can I customize theme to match overflow menu's background color to RGB (245, 243, 239), and the font color to RGB (64, 64, 64) in above code?
Thanks in advance..

to change text color you can use :
<item name="android:textAppearanceLargePopupMenu" >#style/m_textAppearanceLargePopupMenu</item>
<item name="android:textAppearanceSmallPopupMenu" >#style/m_textAppearanceSmallPopupMenu</item>
<style name="m_textAppearanceLargePopupMenu" parent="#android:style/TextAppearance.Holo.Widget.PopupMenu.Large">
<item name="android:textColor">#FFF</item>
</style>
<style name="m_textAppearanceSmallPopupMenu" parent="#android:style/TextAppearance.Holo.Widget.PopupMenu.Small">
<item name="android:textColor">#FFF</item>
</style>
this will change the popup menu text color to white

Try this:
<style name="CustomActivityTheme" parent="#android:style/Theme.Holo">
...
<item name="android:popupMenuStyle">#style/MyPopupMenu</item>
...
</style>
<style name="MyPopupMenu" parent="android:style/Widget.Holo.Light.ListPopupWindow">
<item name="android:background">#f5fdef</item>
</style>
I found it at this post

<style name="MyActionBar3" parent="#style/Widget.AppCompat.Light.ActionBar">
<item name="android:background">#color/ActionBarBackground</item>
</style>
<style name="MyActionBarDropDownStyle" parent="">
<item name="android:background">#00FF00</item>
<item name="android:divider">#ff0000</item>
<item name="android:dividerHeight">1dp</item>
<item name="android:textColor">#FFFFFF</item>
<item name="android:textSize">10sp</item>
</style>
<style name="MyTextStyle" parent="#style/Widget.AppCompat.Light.Base.ListPopupWindow">
<item name="android:popupBackground">#FF0000</item>
</style>
Apply the style to android:textAppearanceLargePopupMenu" item's attribute
