SnackBar using ActionBar Theme?

I having this weird behavior with the styling of ActionBar and Snackbar.
I have below theme for AppTheme
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorWhite</item>
<item name="colorPrimaryDark">#color/colorWhiteDark</item>
<item name="colorAccent">#color/colorGreen</item>
</style>
So, I am having white theme. And my SnackBar looks like this
But, whenever I add custom actionBarTheme, like
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorWhite</item>
<item name="colorPrimaryDark">#color/colorWhiteDark</item>
<item name="colorAccent">#color/colorGreen</item>
<item name="actionBarTheme">#style/ActionbarTheme</item>
</style>
<style name="ActionbarTheme">
<item name="android:textColor">#color/colorBlack</item>
<item name="android:background">#color/colorWhite</item>
</style>
My SnackBar looks like this
Why it is causing this behavior and how to fix it?

Since you are applying following style in your parent
<style name="ActionbarTheme">
<item name="android:textColor">#color/colorBlack</item>
<item name="android:background">#color/colorWhite</item>
</style>
Your text color is black and your background is white.
EDIT:
To fix, you need to set textcolor as white and background black:
<style name="ActionbarTheme">
<item name="android:textColor">#color/colorWhite</item>
<item name="android:background">#color/colorBlack</item>
</style>

change item name background to colorPrimary
<style name="ActionbarTheme">
<item name="android:textColor">#color/colorBlack</item>
<item name="colorPrimary">#color/colorWhite</item>
</style>

Android Changing Action Bar color

I want to change the Action Bar color, but I don't know how to do it. What should I add to change the style?
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>
</resources>

This is all you need to change the color of the action bar:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#995544</item>
</style>

That code works for me and it also changes text color
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</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="background">#color/colorPrimary</item>
<item name="android:height">150dp</item>
<item name="height">60dp</item>
</style>
<style name="AppTheme.ActionBar.TitleText" parent="TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textSize">15dp</item>
<item name="android:textColor">#color/colorAccent</item>
</style>

simple a single Line code
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.red)));

If your minSdk is 21 or higher, you can add the following:
<item name="colorPrimary">#color/yourColor</item>
If not then make the following changes:
Your activity must extend AppCompatActivity
Change your theme to #style/Theme.AppCompat.Light.NoActionBar
Add this to the top of your activity xml file:
<android.support.v7.widget.Toolbar
android:id="#+id/my_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"/>
Put this in your onCreate method after the super.onCreate call:
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
To change the color just replace ?attr/colorPrimary with #color/yourColor

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
</style
Here colorPrimary attribute helps you to change the color of action bar.
For more details see this fig.

Please try the code below:
<style name="AppCompatTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:background">#ff540e9e</item>
<item name="android:textColor">#ffffff</item>
</style>

At your theme.xml or/and theme.xml (dark), change the following android:statusBarColor which change the to status bar background color, toolbarNavigationButtonStyle change the back button color, actionBarStyle change the background and text color and displayOptions to show the text.
<style name="Theme.Example" parent="Theme.AppCompat.DayNight.DarkActionBar">
<!-- Status bar color. -->
<item name="android:statusBarColor">#color/backgroundDark</item>
<!-- action bar color. -->
<item name="toolbarNavigationButtonStyle">#style/Toolbar.Button.Navigation.Tinted</item>
<item name="actionBarStyle">#style/Actionbar.dark</item>
<item name="displayOptions">showHome|useLogo|showTitle</item>
</style>
<style name="Actionbar.dark" parent="Widget.AppCompat.Toolbar.Button.Navigation">
<item name="background">#color/backgroundDark</item>
<item name="titleTextStyle">#style/Actionbar.darktext</item>
</style>
<style name="Actionbar.darktext" parent="#style/TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textColor">#color/white</item>
</style>
<style name="Toolbar.Button.Navigation.Tinted" parent="Widget.AppCompat.Toolbar.Button.Navigation">
<item name="tint">#color/white</item>
</style>

You can customize the current theme for your app, in the res/values/styles.xml file try:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
// your custom styles added to theme
<item name="android:actionBarStyle">#style/MyActionBarTheme</item>
</style>
//Cutomise your theme by specifying layout,color, font type etc:
<style name="MyActionBarTheme"
parent="#android:style/Widget.AppCompat.Light.DarkActionBar">
// sets the background color of the activity/app:
<item name="android:background">#33FF33</item>
</style>
Then you will need to add your new custom theme name to your apps Manifest file

How to change android button text color globally in theme

How can I change all my buttons text color?
I know I can set the background color like follows :
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
...
<item name="colorButtonNormal">#color/buttonColor</item>
</style>
How can I do this for the button Text?

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:textColor">#yourcolor</item>
<item name="android:buttonStyle">#style/ButtonColor</item>
<item name="colorButtonNormal">#color/buttonColor</item>
</style>
<style name="ButtonColor" parent="#android:style/Widget.Button">
<item name="android:textColor">#color/yourcolor</item>
</style>
android:textColor This should help you change the text color globally.

With the new Theme.MaterialComponents theme you can define the materialButtonStyle attribute in your app theme, to customize globally the style of all buttons in your app.
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light">
<!-- .... -->
<item name="materialButtonStyle">#style/Widget.App.Button</item>
</style>
With
<style name="Widget.App.Button" parent="Widget.Material3.Button">
<!-- button style customization example -->
<item name="materialThemeOverlay">#style/ThemeOverlay.App.Button</item>
<item name="android:textAppearance">#style/TextAppearance.App.Button</item>
<item name="shapeAppearance">#style/ShapeAppearance.App.SmallComponent</item>
</style>
Use Widget.MaterialComponents.Button as parent if you are using Material2 theme.
If you would like to override only some attributes like colors from the default style use the materialThemeOverlay attribute.
Something like:
<style name="Widget.App.Button" parent="Widget.Material3.Button">
<item name="materialThemeOverlay">#style/ThemeOverlay.App.Button</item>
</style>
<style name="ThemeOverlay.App.Button">
<!-- For filled buttons, your theme's colorPrimary provides the default background color of the component, and -->
<!--the text color is colorOnPrimary -->
<item name="colorPrimary">#color/my_color</item>
<item name="colorOnPrimary">#color/my_color2</item>
</style>

If you just need to change the text colour of buttons. You can modify the textAppearanceButton style attribute of your main theme.
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorButtonNormal">#color/buttonColor</item>
<item name="android:textAppearanceButton">#style/TextAppearance.AppCompat.Button.Custom</item>
</style>
And declare your new textAppearance style as follows
<style name="TextAppearance.AppCompat.Button.Custom">
<item name="android:textColor">#color/mycustomcolor</item>
</style>

For anyone that stumbles onto this, I recommend checking out a similar question about Material Design Button Styles. With a theme, your "accent color" will be used to color your button.
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
...
<item name="android:buttonStyle">#style/Widget.AppCompat.Button.Colored</item>
<item name="buttonStyle">#style/Widget.AppCompat.Button.Colored</item>
</style>

Since MaterialComponents Buttons use colorPrimary by default you can simply set colorOnPrimary in your theme when using Theme.MaterialComponents.Light, don't know if it's the same with Material3.
<resources>
<!-- Base application theme. -->
<style name="Base.Theme.MyApplication" parent="Theme.MaterialComponents.Light">
<!-- Customize your light theme here. -->
...
<item name="colorOnPrimary">#color/colorOnPrimary</item>
</style>
<style name="Theme.MyApplication" parent="Base.Theme.MyApplication" />
</resources>

Just using AppCompatButton by setting this attribute :
"app:backgroundTint="#color/wildberries"
And make sure your activity extends AppCompatActivity. I just use it in my project. It works like a charm in both 5.X and pre-5.X.

<Button
app:backgroundTint="#fece2f" //any color
/>
This is best way if you don't want it to be defined globally

Changing the colour of actionbar hides the settings button

I tried to change the colour of actionbar by making few changes in default theme.
But the problem is when the colour changes, it hides the settings button.please suggest me the changes.
Heres the xml file for styles.xml:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorWhite</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:windowActionBarOverlay">true</item>
</style>

You can add the android:textColorSecondary attribute to your theme.
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
.....
<!-- color of the menu overflow icon -->
<item name="android:textColorSecondary">#color/my_color</item>
</style>
Otherwise, since you are using a white Toolbar, you can use override the theme with:
<android.support.v7.widget.Toolbar
app:theme="#style/ThemeToolbar" />
with:
<style name="ThemeToolbar" parent="Theme.AppCompat.Light">
<!-- navigation icon color -->
<item name="colorControlNormal">#color/my_color</item>
<!-- color of the menu overflow icon -->
<item name="android:textColorSecondary">#color/my_color</item>
</style>

can we set actionbar height manually in android theme.light

I am using "Theme.Light" theme for my android project and while setting up a navigation drawer how can i set actionbar size(height).
I used the below code and i got an error..
<style name="Theme.Light.ActionBar" parent="#android:style/Theme.Light">
<item name="android:windowNoTitle">false</item>
<item name="android:windowActionBar">true</item>
<item name="actionBarSize">36dip</item>
<item name="android:windowActionBarOverlay">true</item>
</style>
can you please reply to my problem as soon as possible and thank you.

Use height attribute,for actionBarHeight
<item name="android:height">#dimen/bar_height</item>
you have to create style like this:
<!-- 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="titleTextStyle">#style/AppTheme.ActionBar.TitleText</item>
<item name="android:titleTextStyle">#style/AppTheme.ActionBar.TitleText</item>
<item name="android: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>
you have to try below code :
<resources>
<style name="Theme.FixedSize" parent="#android:style/Theme.Holo.Light.DarkActionBar">
<item name="actionBarSize">48dip</item>
<item name="android:actionBarSize">48dip</item>
</style>
</resources>

If you are using AppCompat, you can set the "actionBarSize" attribute in your theme (which must inherit from Theme.AppCompat.x). You can also use a Toolbar in your layout and set its layout_height to the desired value.
