How to combine style into a theme?

I have created a style:
<style name="Button_Display">
<item name="android:minHeight">48dip</item>
<item name="android:minWidth">88dip</item>
<item name="android:focusable">true</item>
<item name="android:clickable">true</item>
<item name="android:gravity">center_vertical|center_horizontal</item>
</style>
I want that all the Button's in my application will look like declared above.
My question is how can i combine the Button_Display style inside a theme so all the Buttons in my app will have this look and feel?

https://developer.android.com/guide/topics/ui/look-and-feel/themes
In styles.xml create your own button style. Choose whatever parent style matches your need the best. Then overwrite all the necessary parameters.
<style name="myButtonStyle" parent="#style/Widget.AppCompat.Button">
<item name="android:minHeight">48dip</item>
<item name="android:minWidth">88dip</item>
...
</style>
Then set this as default button style in your theme.
<style name="AppTheme" parent="Theme.AppCompat....">
<item name="buttonStyle">#style/myButtonStyle</item>
...
</style>
Now all Buttons will have the parameters you specified in your style.

I want to change title bar text color in material Components theme. Any help will be greatly appreciated

I tried set title color but it is deprecated. I tried to change color by using
<style name="MyTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">#style/MyTheme.ActionBarStyle</item>
</style>
<style name="MyTheme.ActionBarStyle" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:titleTextStyle">#style/MyTheme.ActionBar.TitleTextStyle</item>
</style>
<style name="MyTheme.ActionBar.TitleTextStyle" parent="#android:style/TextAppearance.Holo.Widget.ActionBar.Title">
<item name="android:textColor">#color/red</item>
</style>
as mentioned here: ActionBar text color but the whole Titlebar color changes to white while doing it.
All I want to do is set my Black Title bar text color to white.
I also tried this solution here: Change color title bar but I am using the MaterialComponents theme and using AppCompactThemes makes my app crash.

Assuming that you are not using a Toolbar the textcolor used in the ActionBar is based on the attribute android:textColorPrimary.
You can override it adding in your app theme the actionBarTheme attribute:
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight">
<item name="actionBarTheme">#style/ThemeOverlay.Actionbar</item>
</style>
with:
<style name="ThemeOverlay.Actionbar" parent="ThemeOverlay.MaterialComponents.ActionBar.Surface" >
<item name="android:textColorPrimary">#color/....</item>
</style>
As alternative you can

just add this to you base theme
<item name="titleTextColor">#android:color/holo_red_dark</item> //whatever color
Eg:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="titleTextColor">#android:color/holo_green_dark</item>
</style>

Remove Transparent Background in Toolbar Fragment

I am using a toolbar in which the overflow menu options have a transparent background as shown in the image transparent overflow menu in toolbar
I have tried editing the default theme and also tried out a custom theme as well as using a panel background option.
Could someone please let me know how to make the background of the overflow menu in the toolbar not transparent?

change your base theme as below one it should work as its working for me just compiled now. just add this
<item name="android:itemBackground">#color/colorPrimaryDark</item>
Theme:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:itemBackground">#color/colorPrimaryDark</item>
</style>

How to change color of the back arrow in the new material theme?

I've updated my SDK to API 21 and now the back/up icon is a black arrow pointing to the left.
I would like it to be grey. How can I do that?
In the Play Store, for example, the arrow is white.
I've done this to set some styles. I have used #drawable/abc_ic_ab_back_mtrl_am_alpha for homeAsUpIndicator. That drawable is transparent (only alpha) but the arrow is displayed in black. I wonder if I can set the color like I do in the DrawerArrowStyle. Or if the only solution is to create my #drawable/grey_arrow and use it for homeAsUpIndicator.
<!-- Base application theme -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="android:actionBarStyle" tools:ignore="NewApi">#style/MyActionBar</item>
<item name="actionBarStyle">#style/MyActionBar</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
<item name="homeAsUpIndicator">#drawable/abc_ic_ab_back_mtrl_am_alpha</item>
<item name="android:homeAsUpIndicator" tools:ignore="NewApi">#drawable/abc_ic_ab_back_mtrl_am_alpha</item>
</style>
<!-- ActionBar style -->
<style name="MyActionBar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid">
<item name="android:background">#color/actionbar_background</item>
<!-- Support library compatibility -->
<item name="background">#color/actionbar_background</item>
</style>
<!-- Style for the navigation drawer icon -->
<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
<item name="color">#color/actionbar_text</item>
</style>
My solution so far has been to take the #drawable/abc_ic_ab_back_mtrl_am_alpha, which seems to be white, and paint it in the color I desire using a photo editor. It works, although I would prefer to use #color/actionbar_text like in DrawerArrowStyle.

You can achieve it through code. Obtain the back arrow drawable, modify its color with a filter, and set it as back button.
final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
upArrow.setColorFilter(getResources().getColor(R.color.grey), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setHomeAsUpIndicator(upArrow);
Revision 1:
Starting from API 23 (Marshmallow) the drawable resource abc_ic_ab_back_mtrl_am_alpha is changed to abc_ic_ab_back_material.
EDIT:
You can use this code to achieve the results you want:
toolbar.getNavigationIcon().setColorFilter(getResources().getColor(R.color.blue_gray_15), PorterDuff.Mode.SRC_ATOP);

Looking at the Toolbar and TintManager source, drawable/abc_ic_ab_back_mtrl_am_alpha is tinted with the value of the style attribute colorControlNormal.
I did try setting this in my project (with <item name="colorControlNormal">#color/my_awesome_color</item> in my theme), but it's still black for me.
Update:
Found it. You need to set the actionBarTheme attribute (not actionBarStyle) with colorControlNormal.
Eg:
<style name="MyTheme" parent="Theme.AppCompat.Light">
<item name="actionBarTheme">#style/MyApp.ActionBarTheme</item>
<item name="actionBarStyle">#style/MyApp.ActionBar</item>
<!-- color for widget theming, eg EditText. Doesn't effect ActionBar. -->
<item name="colorControlNormal">#color/my_awesome_color</item>
<!-- The animated arrow style -->
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
</style>
<style name="MyApp.ActionBarTheme" parent="#style/ThemeOverlay.AppCompat.ActionBar">
<!-- THIS is where you can color the arrow! -->
<item name="colorControlNormal">#color/my_awesome_color</item>
</style>
<style name="MyApp.ActionBarStyle" parent="#style/Widget.AppCompat.Light.ActionBar">
<item name="elevation">0dp</item>
<!-- style for actionBar title -->
<item name="titleTextStyle">#style/ActionBarTitleText</item>
<!-- style for actionBar subtitle -->
<item name="subtitleTextStyle">#style/ActionBarSubtitleText</item>
<!--
the actionBarTheme doesn't use the colorControlNormal attribute
<item name="colorControlNormal">#color/my_awesome_color</item>
-->
</style>

Tried all suggestions above. The only way that I managed to change the color of navigation icon default Back button arrow in my toolbar is to set colorControlNormal in base theme like this. Probably due to the fact that the parent is using Theme.AppCompat.Light.NoActionBar
<style name="BaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorControlNormal">#color/white</item>
//the rest of your codes...
</style>

Need to add a single attribute to your toolbar theme -
<style name="toolbar_theme" parent="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="colorControlNormal">#color/arrow_color</item>
</style>
Apply this toolbar_theme to your toolbar.
OR
you can directly apply to your theme -
<style name="CustomTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorControlNormal">#color/arrow_color</item>
//your code ....
</style>

Just add
<item name="colorControlNormal">#color/white</item>
to your current app theme.

if use Toolbar,you can try this
Drawable drawable = toolbar.getNavigationIcon();
drawable.setColorFilter(ContextCompat.getColor(appCompatActivity, colorId), PorterDuff.Mode.SRC_ATOP);

As said on most of the previous comments, the solution is to add
<item name="colorControlNormal">#color/white</item>
to your app theme.
But confirm that you don´t have another theme defined in your Toolbar element on your layout.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />

The answer by Carles is the correct answer, but few of the methods like getDrawable(), getColor() got deprecated at the time I am writing this answer. So the updated answer would be
Drawable upArrow = ContextCompat.getDrawable(context, R.drawable.abc_ic_ab_back_mtrl_am_alpha);
upArrow.setColorFilter(ContextCompat.getColor(context, R.color.white), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setHomeAsUpIndicator(upArrow);
Following some other stackoverflow queries I found that calling ContextCompat.getDrawable() is similar to
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
return resources.getDrawable(id, context.getTheme());
} else {
return resources.getDrawable(id);
}
And ContextCompat.getColor() is similar to
public static final int getColor(Context context, int id) {
final int version = Build.VERSION.SDK_INT;
if (version >= 23) {
return ContextCompatApi23.getColor(context, id);
} else {
return context.getResources().getColor(id);
}
}
Link 1: ContextCompat.getDrawable()
Link 2: ContextCompat.getColor()

I found a solution that works pre Lollipop. Set the "colorControlNormal" within the "actionBarWidgetTheme" to change the homeAsUpIndicator color. Modifying rockgecko's answer from above to look like this:
<style name="MyTheme" parent="Theme.AppCompat.Light">
<item name="actionBarTheme">#style/MyApp.ActionBarTheme</item>
<item name="actionBarStyle">#style/MyApp.ActionBar</item>
<!-- color for widget theming, eg EditText. Doesn't effect ActionBar. -->
<item name="colorControlNormal">#color/my_awesome_color</item>
<!-- The animated arrow style -->
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
<!-- The style for the widgets on the ActionBar. -->
<item name="actionBarWidgetTheme">#style/WidgetStyle</item>
</style>
<style name="WidgetStyle" parent="style/ThemeOverlay.AppCompat.Light">
<item name="colorControlNormal">#color/my_awesome_color</item>
</style>

On compileSdkVersoin 25, you could do this:
styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="android:textColorSecondary">#color/your_color</item>
</style>

Change Menu Nav Icon Color
In style.xml :
<style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
<item name="android:textColor">#color/colorAccent</item>
</style>
<style name="DrawerArrowStyle" parent="#style/Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
<item name="color">#color/colorPrimaryDark</item>
</style>
In Mainfests.xml :
<activity android:name=".MainActivity"
android:theme="#style/MyMaterialTheme.Base"></activity>

Use below method:
private Drawable getColoredArrow() {
Drawable arrowDrawable = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
Drawable wrapped = DrawableCompat.wrap(arrowDrawable);
if (arrowDrawable != null && wrapped != null) {
// This should avoid tinting all the arrows
arrowDrawable.mutate();
DrawableCompat.setTint(wrapped, Color.GRAY);
}
return wrapped;
}
Now you can set the drawable with:
getSupportActionBar().setHomeAsUpIndicator(getColoredArrow());

Solution is very simple
Just put following line into your style named as AppTheme
<item name="colorControlNormal">#color/white</item>
Now your whole xml code will look like shown below (default style).
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#0F0F0F</item>
<item name="android:statusBarColor">#EEEEF0</item>
<item name="android:windowLightStatusBar">true</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:windowActivityTransitions">true</item>
<item name="colorControlNormal">#color/white</item>
</style>

Another solution that might work for you is to not declare your toolbar as the app's action bar ( by setActionBar or setSupportActionBar ) and set the back icon in your onActivityCreated using the code mentioned in another answer on this page
final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
upArrow.setColorFilter(getResources().getColor(R.color.grey), PorterDuff.Mode.SRC_ATOP);
toolbar.setNavigationIcon(upArrow);
Now, you will not get the onOptionItemSelected callback when you press the back button. However, you can register for that using setNavigationOnClickListener. This is what i do:
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
getActivity().onBackPressed(); //or whatever you used to do on your onOptionItemSelected's android.R.id.home callback
}
});
I'm not sure if it will work if you work with menu items.

This is what worked for me:
Add the below attributes to your theme.
To change toolbar/actionbar back arrow above api 21
<item name="android:homeAsUpIndicator">#drawable/your_drawable_icon</item>
To change toolbar/actionbar back arrow below api 21
<item name="homeAsUpIndicator">#drawable/your_drawable_icon</item>
To change action mode back arrow
<item name="actionModeCloseDrawable">#drawable/your_drawable_icon</item>
To remove toolbar/actionbar shadow
<item name="android:elevation" tools:targetApi="lollipop">0dp</item>
<item name="elevation">0dp</item>
<!--backward compatibility-->
<item name="android:windowContentOverlay">#null</item>
To change actionbar overflow drawable
<!--under theme-->
<item name="actionOverflowButtonStyle">#style/MenuOverflowStyle</item>
<style name="MenuOverflowStyle" parent="Widget.AppCompat.ActionButton.Overflow">
<item name="srcCompat">#drawable/ic_menu_overflow</item>
Note : 'srcCompat' is used instead of 'android:src' because of vector drawable support for api below 21

Here's how I did it in Material Components:
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
<item name="drawerArrowStyle">#style/AppTheme.DrawerArrowToggle</item>
</style>
<style name="AppTheme.DrawerArrowToggle" parent="Widget.AppCompat.DrawerArrowToggle">
<item name="color">#android:color/white</item>
</style>

We were running into the same problem and all we wanted was to set the
app:collapseIcon
attribute in the toolbar in the end, which we did not find since it is not very well documented :)
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="#dimen/toolbarHeight"
app:collapseIcon="#drawable/collapseBackIcon" />

try this
public void enableActionBarHomeButton(AppCompatActivity appCompatActivity, int colorId){
final Drawable upArrow = ContextCompat.getDrawable(appCompatActivity, R.drawable.abc_ic_ab_back_material);
upArrow.setColorFilter(ContextCompat.getColor(appCompatActivity, colorId), PorterDuff.Mode.SRC_ATOP);
android.support.v7.app.ActionBar mActionBar = appCompatActivity.getSupportActionBar();
mActionBar.setHomeAsUpIndicator(upArrow);
mActionBar.setHomeButtonEnabled(true);
mActionBar.setDisplayHomeAsUpEnabled(true);
}
function call:
enableActionBarHomeButton(this, R.color.white);

I just changed the toolbar theme to be #style/ThemeOverlay.AppCompat.Light
and the arrow became dark gray
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:gravity="center"
app:layout_collapseMode="pin"
app:theme="#style/ThemeOverlay.AppCompat.Light">

The simplest (and best) way to change the color of the back/up-arrow. Best part is
that there are no side-effects (unlike the other answers)!
Create a style with parent Widget.AppCompat.DrawerArrowToggle, define the color and any other attributes you'd like.
Set the style on the drawerArrowStyle attribute in the apps Theme.
Create style:
<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
<!-- Set that the nav buttons will animate-->
<item name="spinBars">true</item>
<!-- Set the color of the up arrow / hamburger button-->
<item name="color">#color/white</item>
</style>
Set the style in App Theme:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<!-- Change global up-arrow color with no side-effects -->
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
</style>
To change the ToolBar text color (and other attributes), create this style:
<style name="ToolbarStyle" parent="Widget.AppCompat.Toolbar">
<item name="android:textColor">#color/white</item>
<item name="titleTextColor">#color/white</item>
<item name="colorControlNormal">#color/white</item> <!-- colorControlNormal is Probably not necessary -->
</style>
Then set that style on the AppTheme:
<!-- Base application theme. -->
<style name="AppTheme.MyProduceApp" parent="Theme.MaterialComponents.Light.NoActionBar.Bridge">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<!-- Style the toolbar (mostly the color of the text) -->
<item name="toolbarStyle">#style/ToolbarStyle</item>
<!-- Change color of up-arrow -->
<item name="drawerArrowStyle">#style/DrawerArrowStyle</item>
</style>

You can change the color of the navigation icon programmatically like this:
mToolbar.setNavigationIcon(getColoredArrow());
private Drawable getColoredArrow() {
Drawable arrowDrawable = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
Drawable wrapped = DrawableCompat.wrap(arrowDrawable);
if (arrowDrawable != null && wrapped != null) {
// This should avoid tinting all the arrows
arrowDrawable.mutate();
DrawableCompat.setTintList(wrapped, ColorStateList.valueOf(this.getResources().getColor(R.color.your_color)));
}
}
return wrapped;
}

private fun setToolbarNavigationIconColor(context: Context, toolbar: Toolbar?, color: Int) {
val drawableBack = toolbar?.navigationIcon
drawableBack?.let {
val drawableWrap = DrawableCompat.wrap(drawableBack).mutate()
DrawableCompat.setTint(
drawableWrap, ContextCompat.getColor(context, white)
)
toolbar.navigationIcon = drawableWrap
}
}

I saw all soluation but didn't fix the problem , If you need fix the problem just add in XMl file this code if you but dark make it light
app:theme="#style/ThemeOverlay.AppCompat.Light"

Just remove android:homeAsUpIndicator and homeAsUpIndicator from your theme and it will be fine. The color attribute in your DrawerArrowStyle style must be enough.

Unless there's a better solution...
What I did is to take the #drawable/abc_ic_ab_back_mtrl_am_alpha images, which seem to be white, and paint them in the color I desire using a photo editor.

Change the action bar settings icon color

How can one change the color of the overflow icon in the action bar?
(The most right icon)

You can use something like this
<style name="MyTheme" parent="android:style/Theme.Holo.Light">
<item name="android:actionOverflowButtonStyle">#style/MyActionButtonOverflow</item>
</style>
<style name="MyActionButtonOverflow" parent="android:style/Widget.Holo.ActionButton.Overflow">
<item name="android:src">#drawable/my_action_bTutton_overflow</item>
</style>
in your AndroidManifest.xml
<application
android:theme="#style/MyTheme" >
If you want to change actionBar color
#style/MyActionBar
<!-- Support library compatibility -->
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
<!-- ActionBar styles -->
<style name="MyActionBar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="android:background">#color/app_theme_color</item>
<!-- Support library compatibility -->
<item name="background">#color/app_theme_color</item>
<item name="android:alwaysDrawnWithCache">true</item>
<item name="android:displayOptions">showTitle|showHome|homeAsUp</item>
<item name="android:icon">#android:color/transparent</item>
</style>
Then in your AndroidManifest.xml you need to refer this one inside your application tag.
android:theme="#style/CustomActionBarTheme"

If you just want to change the color you can simply tint it:
<style name="DotsDarkTheme" parent="#style/Widget.AppCompat.ActionButton.Overflow" >
<item name="android:tint">#color/yourColor</item>
</style>
and then use it in your style:
<item name="actionOverflowButtonStyle">#style/DotsDarkTheme</item>

if you are using action bar use :
toolbar.getOverflowIcon().setColorFilter(Color.WHITE , PorterDuff.Mode.SRC_ATOP);

It's also worth adding that if you simply want to change the overflow button to a light or dark colour to go with your action bar colour this can be done without specifying a custom icon.
For a dark button colour set your theme as:
<style name="MyTheme" parent="#style/Theme.AppCompat.Light">
<item name="android:actionBarStyle">#style/MyTheme.ActionBar</item>
</style>
For a light button colour add DarkActionBar:
<style name="MyTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/MyTheme.ActionBar</item>
</style>
If, like me, you want a light button colour but you want the overflow menu to be light you can do the following:
<style name="MyTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/MyTheme.ActionBar</item>
<item name="android:actionBarWidgetTheme">#style/MyTheme.ActionBarWidget</item>
</style>
<!-- This helps the PopupMenu stick with Light theme while the ActionBar is in Dark theme -->
<style name="MyTheme.ActionBarWidget"
parent="android:Theme.Holo.Light">
<item name="android:popupMenuStyle">#android:style/Widget.Holo.Light.PopupMenu</item>
<item name="android:dropDownListViewStyle">#android:style/Widget.Holo.Light.ListView.DropDown</item>
</style>

You can use your custom style inside for menu item, like this
<item name="android:itemTextAppearance">#style/myCustomMenuTextApearance</item>
Define the style like this:
<style name="myCustomMenuTextApearance" parent="#android:style/TextAppearance.Widget.IconMenu.Item">
<item name="android:textColor">#android:color/primary_text_dark</item>
</style>
Also see Change the background color of the options menu and
Android: customize application's menu (e.g background color)

Create below style in styles.xml with parent as ActionButton Overflow widget
and then use that theme in the style that you are using for that activity where toolbar is shown.
Step-1) Creating style for the actionButtonOverflow
<style name="DotsDarkTheme" parent="#style/Widget.AppCompat.ActionButton.Overflow" >
<item name="android:tint">your color</item>
</style>
Step-2) Using this style in the activity that is using actionBar
<style name="CustomMainActivityTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="actionOverflowButtonStyle">#style/DotsDarkTheme</item>
</style>
