I am currently trying to change the colors of the icons in the toolbar via the theme (I know the way to do it via kotlin but I am interested to be able to do it on the whole app via a theme). Even though I read the google doc on this subject and several topics, I was not able to change the color of these icons. I'm using MaterialTheme
Manifest where I defined my theme and my activity :
<application
android:name=".App"
android:theme="#style/Theme.MyApp">
<activity
android:name=".views.activity"
android:label="#string/title_activity" />
</application>
Themes.xml
<!--Top level DayNight theme to be used in AndroidManifest.xml-->
<style name="Theme.MyApp" parent="Base.Theme.MyApp" />
<!--Base custom theme which will be shared between both light and dark theme variants-->
<style name="Base.Theme.MyApp" parent="Base.Theme.MaterialThemeBuilder">
<!--Material color attributes (light theme) -->
<!--colorPrimary colors map to components and elements, such as app bars and buttons. -->
<!--colorSecondary colors are most often used as accents on components, such as FABs and -->
<!--selection controls.-->
<item name="colorPrimary">#color/primaryColor</item>
<item name="colorPrimaryVariant">#color/primaryLightColor</item>
<item name="colorSecondary">#color/secondaryColor</item>
<item name="colorSecondaryVariant">#color/secondaryLightColor</item>
<!--colorBackground appears behind scrollable content and is used for the default window-->
<!--background. colorSurface is mapped to the surface of components such as cards, sheets-->
<!--and menus. colorError is used to indicate an error state for components such as-->
<!--text fields.-->

<item name="colorSurface">#color/black_800</item>
<item name="colorError">#color/red_600</item>
<!--"On" colors define how text, icons and strokes are colored in relation to the surface-->
<!--on which they appear.-->
<item name="colorOnPrimary">#color/black_800</item>
<item name="colorOnSecondary">#color/black_800</item>
<item name="colorOnBackground">#color/black_800</item>
<item name="colorOnSurface">#color/black_800</item>
<item name="colorOnError">#color/white</item>
<!--Material type attributes-->
...
<!--Material shape attributes-->
...
<item name="toolbarStyle">#style/Widget.MyTheme.Toolbar</item>
</style>
Styles.xml
<!--Toolbar-->
<style name="Widget.MyTheme.Toolbar" parent="Widget.MaterialComponents.Toolbar.Surface"> // I have also try ThemeOVerlay here and Toolbar.Primary
<item name="android:background">#color/grey_200</item>
<item name="titleTextAppearance">#style/TextAppearance.MyTheme.Headline6</item>
<item name="subtitleTextAppearance">#style/TextAppearance.MyTheme.Subtitle1</item>
<item name="titleTextColor">#color/black_800</item>
<!-- color used by navigation icon and overflow icon -->
<item name="colorOnPrimary">#color/red_800</item>
<item name="colorControlNormal">#color/red_800</item>
</style>
As you can see the toolbar is provided by the theme so the activity xml is not revelant here. My icons are in vector format, generated via AndroidStudio. I have try this solution but not working :/
The solution linked in the question works but you are using a style (with style="..") not a theme overlay (with android:theme="..").
<style name="Base.Theme.MyApp" parent="Base.Theme.MaterialThemeBuilder">
<item name="toolbarStyle">#style/Widget.MyTheme.Toolbar</item>
</style>
With the theme attribute toolbarStyle you are using a style:
<style name="Widget.MyTheme.Toolbar" parent="Widget.MaterialComponents.Toolbar">
<!-- Title text color -->
<item name="titleTextColor">#color/colorSecondary</item>
<!-- ..... -->
<!-- ThemeOverlay -->
<item name="materialThemeOverlay">#style/MyThemeOverlay_Toolbar</item>
</style>
<style name="MyThemeOverlay_Toolbar" parent="ThemeOverlay.MaterialComponents.Toolbar.Primary">
<!-- color used by navigation icon and overflow icon -->
<item name="colorOnPrimary">#color/red600Dark</item>
</style>
and in your layout use a MaterialToolbar:
<com.google.android.material.appbar.MaterialToolbar
.../>

I would like to change the action bar size. I have tried the following coding.
<style name="MyTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">#style/CustomActionBar</item>
</style>
<style name="CustomActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<!-- <item name="android:background">#drawable/action_bar_style</item> -->
<item name="android:actionBarSize">15dp</item>
<item name="android:background">#drawable/header_bar</item>
</style>
But the action bar size didn't change. Is there another way? I am using api level 11.
Thanks.
Use height attribute, actionBarSize if for something else.
<item name="android:height">#dimen/bar_height</item>
Explanantion:
From source code of ActionBar:
mContentHeight = a.getLayoutDimension(R.styleable.ActionBar_height, 0);
We can see that R.styleable.ActionBar_height is being used for height. Stylable property names are generated as component_attribute (If you have ever used a custom stylable view, you'd have notice this). Hence, Actionbar is the name of component and height is the name of the attribute to use. Since this is a system attribute, hence defined under android namespace.
Update Dec-2014:
AppCompat library is now provided to extend support for latest ActionBar (or Toolbar) and theme support to old android versions. Below is an example of such an application theme /res/values/styles.xml:
<resources>
<!-- Application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<!-- Main theme colors -->
<!-- your app branding color for the app bar -->
<item name="colorPrimary">#color/primary</item>
<!-- darker variant for the status bar and contextual app bars -->
<item name="colorPrimaryDark">#color/primary_dark</item>
<!-- theme UI controls like checkboxes and text fields -->
<!-- native widgets will now be "tinted" with accent color -->
<item name="colorAccent">#color/accent</item>
<!--Action bar style-->
<item name="android:actionBarStyle">#style/AppTheme.ActionBar</item>
<item name="actionBarStyle">#style/AppTheme.ActionBar</item>
</style>
<style name="AppTheme.ActionBar" parent="Widget.AppCompat.Light.ActionBar">
<item name="android:titleTextStyle">#style/AppTheme.ActionBar.TitleText</item>
<item name="titleTextStyle">#style/AppTheme.ActionBar.TitleText</item>
<item name="android:height">#dimen/bar_height</item>
<item name="height">#dimen/bar_height</item>
</style>
<style name="AppTheme.ActionBar.TitleText" parent="TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textSize">#dimen/bar_text_size</item>
<item name="android:textColor">#color/bar_text_color</item>
</style>
</resources>
This style can now be set as app theme by using android:theme="#style/AppTheme" in <application> tag of the AndroidManifest.xml.
Note the use of duplicate entries
<item name="android:actionBarStyle">
<item name="actionBarStyle">
The ones without android namespace are there for supporting both compatibility library and native attributes.Some of these attributes didn't exist under android namespace on older versions and belong to support library.
In some other places, you'll need to use app namespace (xmlns:app="http://schemas.android.com/apk/res-auto"), for example app:showAsAction="always" in menu xml files.

AppCompat Library v22 is also available. Read through the article to know what's new.
Simply put actionBarSize item under MyTheme style, like this:
<style name="MyTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarSize">15dp</item>
<item name="actionBarSize">15dp</item>
...
</style>
Explanation:
In R.styleable we see that R.styleable.Theme_actionBarSize is a styleable attribute defined at Theme level.
Also, from source code res/values/styles.xml we see how actionBarSize is used to set height:
<style name="Widget.ActionBar">
...
<item name="android:height">?android:attr/actionBarSize</item>
Add this to the custom theme style XML that you are referencing from your manifest file:
<item name="android:windowTitleSize">58dip</item>
For instance if your manifest file looks something like this:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
**android:theme="#style/AppTheme"** >
Your theme style should be -at least- like this:
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:windowTitleSize">54dip</item>
</style>
S.D.'s solution does not work for me.
I used AppCompat v-21 library in my case.
And I just add
android:layout_height="#dimen/actionBarSize"
android:minHeight="#dimen/actionBarSize"
to my layout file and it works.
Make sure to add S.D.'s code to styles.xml and then add
android:theme="#style/thin_ab"
to the <application> element in the main manifest. (I'm a noob and it took me about 2 hours to find that out.)
I have used the <ContentPage.ToolbarItems> in my code ti display a menu on the top right of the app. My app is only targeting Android at the moment even though it's written in Xamarin.Forms.
I am struggling to change the three dots icon. Any idea how I can achieve that either using Custom Renderer, Effects or styles.xml?
I have seen answers on this overflow but they are all referring to native android and I am struggling to understand how I can do it on Xamarin.Forms.
Thanks!
You can modify style.xml to achieve that .No mattter in forms or native , this will work .
Add item inside MainTheme.Base :
<item name="actionOverflowButtonStyle">#style/OverflowButtonStyle</item>
Then adding style inside resourses :
<style name="OverflowButtonStyle" parent="#android:style/Widget.ActionButton.Overflow">
<item name="android:src">#drawable/circle</item> //here set the wanted icon
</style>
The full style.xml is :
<?xml version="1.0" encoding="utf-8" ?>
<resources>
<style name="MainTheme" parent="MainTheme.Base">
</style>
<!-- Base theme applied no matter what API -->
<style name="MainTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<!--If you are using revision 22.1 please use just windowNoTitle. Without android:-->
<item name="windowNoTitle">true</item>
<!--We will be using the toolbar so no need to show ActionBar-->
<item name="windowActionBar">false</item>
<!-- Set theme colors from https://aka.ms/material-colors -->
<!-- colorPrimary is used for the default action bar background -->
<item name="colorPrimary">#2196F3</item>
<!-- colorPrimaryDark is used for the status bar -->
<item name="colorPrimaryDark">#1976D2</item>
<!-- colorAccent is used as the default value for colorControlActivated
which is used to tint widgets -->
<item name="colorAccent">#FF4081</item>
<!-- You can also set colorControlNormal, colorControlActivated
colorControlHighlight and colorSwitchThumbNormal. -->
<item name="windowActionModeOverlay">true</item>
<item name="actionOverflowButtonStyle">#style/OverflowButtonStyle</item>
<item name="android:datePickerDialogTheme">#style/AppCompatDialogStyle</item>
</style>
<style name="AppCompatDialogStyle" parent="Theme.AppCompat.Light.Dialog">
<item name="colorAccent">#FF4081</item>
</style>
<style name="OverflowButtonStyle" parent="#android:style/Widget.ActionButton.Overflow">
<item name="android:src">#drawable/circle</item>
</style>
</resources>
The effect :
I wish to be able to set a theme to set the message text size in an AppCompat AlertDialog. The theme needs to have parent="#style/Theme.AppCompat.Dialog". I have spent hours searching and trying all the suggestions, but none of them seem to work with that base theme.
If the parent is changed to the Holo theme, then I can alter the message text size using textAppearanceMedium, but the rest of the dialog looks really ugly :S
Currently my theme is (all this is currently hooked up and working):
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyDialogTheme" parent="#style/Theme.AppCompat.Dialog">
<!-- Used for the buttons -->
<item name="colorAccent">#color/colorPrimary</item>
<!-- Button text size -->
<item name="android:textSize">#dimen/ui_text_size</item>
<!-- Content text color -->
<item name="android:textColorPrimary">#color/ui_text_color</item>
<!-- Title style -->
<item name="android:windowTitleStyle">#style/MyDialogTitleStyle</item>
<!-- Button style (except size) -->
<item name="android:textAppearanceButton">#style/MyDialogButtonTextAppearance</item>
<!-- Dialog background -->
<item name="android:windowBackground">#color/ui_background</item>
</style>
<style name="MyDialogTitleStyle" parent="#style/RtlOverlay.DialogWindowTitle.AppCompat">
<item name="android:textAppearance">#style/MyDialogTitleTextAppearance</item>
<item name="android:textSize">#dimen/ui_large_text_size</item>
</style>
<style name="MyDialogTitleTextAppearance">
<item name="android:textSize">#dimen/ui_large_text_size</item>
<item name="android:textAllCaps">true</item>
<item name="android:textColor">#color/ui_title_color</item>
</style>
<style name="MyDialogButtonTextAppearance">
<item name="android:fontFamily">sans-serif-light</item>
<item name="android:textAllCaps">true</item>
</style>
</resources>
Seems like there is no way to this via a theme attribute. Let's look at the source code of appcompat-v7 library. Following the TextView that reflects the message of the AlertDialog:
<android.support.v7.widget.AlertDialogLayout ... >
<!-- ... -->
<TextView
android:id="#android:id/message"
style="#style/TextAppearance.AppCompat.Subhead"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="?attr/dialogPreferredPadding"
android:paddingRight="?attr/dialogPreferredPadding"/>
<!-- ... -->
</android.support.v7.widget.AlertDialogLayout>
As you can see the TextView uses the TextAppearance.AppCompat.Subhead as the style. Following its definition:
<style name="TextAppearance.AppCompat.Subhead" parent="Base.TextAppearance.AppCompat.Subhead"/>
<style name="Base.TextAppearance.AppCompat.Subhead">
<item name="android:textSize">#dimen/abc_text_size_subhead_material</item>
<item name="android:textColor">?android:textColorPrimary</item>
</style>
The textSize is static and isn't resolved via an attribute like the textColor (which uses the textColorPrimary). Thus there's no option for us to set the textSize. The only way to do it would be to override the TextAppearance.AppCompat.Subhead style by adding it to your own styles.xml file and set the textSize to whatever value you need. But be aware there may be side effects since this style can be used in other places as well.
tl;dr
Options:
Define TextAppearance.AppCompat.Subhead in your styles.xml file and override the textSize attribute.
Do it programatically (find TextView by id and #setTextSize)
Use your own layout in the dialog - the source code of appcompat-v7 may be a good starting point.
I have a custom theme that is (mostly) working great. The problem I have is that I cannot figure out a way to change the overflow menu's text color. I realize there are probably ways to do it programmatically but I'm really hoping I can find a solution I can put in the xml.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme.Light" parent="android:Theme.Material.Light.DarkActionBar">
<item name="themeName">Theme.Light</item>
<!--<item name="android:textColor">#ff000000</item>-->
<!-- colorPrimary is used for the default action bar background -->
<item name="android:colorPrimary">#color/blue</item>
<!-- colorPrimaryDark is used for the status bar -->
<item name="android:colorPrimaryDark">#color/medium_blue</item>
<!-- colorAccent is used as the default value for colorControlActivated,
which is used to tint widgets -->
<item name="android:colorAccent">#color/dark_blue</item>
<!-- You can also set colorControlNormal, colorControlActivated
colorControlHighlight, and colorSwitchThumbNormal. -->
<item name="android:actionOverflowMenuStyle">#style/Theme.Light.PopupMenu</item>
<item name="android:textColor">#color/light_text</item>
<item name="android:textColorPrimary">#color/light_text</item>
<item name="actionBarWidgetTheme">#style/MyStyle</item>
</style>
<style name="MyStyle" parent="android:style/Widget">
<item name="android:textColor">#color/dark_text</item>
</style>
<style name="Theme.Light.PopupMenu" parent="android:style/Widget.Material.PopupMenu.Overflow">
<!-- Required for pre-Lollipop. -->
<item name="overlapAnchor">false</item>
<!-- Required for Lollipop. -->
<item name="android:overlapAnchor">false</item>
<item name="android:popupBackground">#color/medium_blue</item>
<item name="android:actionMenuTextColor">#style/Theme.Light.TextAppearance</item>
<item name="android:textColor">#color/dark_text</item>
<item name="android:textColorPrimary">#color/dark_text</item>
</style>
<style name="Theme.Light.TextAppearance">
<item name="android:textColor">#color/dark_text</item>
<item name="android:textColorPrimary">#color/dark_text</item>
</style>
</resources>
I realize this is rather messy but I left in several ways I've attempted to change the textcolor. Basically instead of using the default black for the Material theme, I want to the change the overflow menu textcolor to white.
My guess is there's just some attribute I'm not changing but obviously I don't know what it is. I've searched Google and here but haven't found a solution to this.
EDIT: Setting the textColor for the entire theme does affect the overflow menu's text color but also affects every other text's color, obviously. I'm looking for a more specific attribute.
I would like to change the action bar size. I have tried the following coding.
<style name="MyTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">#style/CustomActionBar</item>
</style>
<style name="CustomActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<!-- <item name="android:background">#drawable/action_bar_style</item> -->
<item name="android:actionBarSize">15dp</item>
<item name="android:background">#drawable/header_bar</item>
</style>
