I'm trying to change my action bar color to royal blue but it stays black despite everything I try. I've set the color code in my color.xml file and the theme is set to AppTheme in AndroidManifest.xml. I don't know what else could cause it to not work. Here is my styles.xml:
<!-- Base application theme. -->
<style name="AppTheme"
parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
<style name="MyActionBar">
<item name="android:background">#color/royal_blue</item>
</style>
It is recommended to use "colorPrimary" for configuring action bar color. You can use following files for styles configuration.You are recomended to use Toolbar to act as ActionBar
values/styles.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- Base application theme. -->
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/primaryColor</item>
<item name="colorPrimaryDark">#color/primaryColorDark</item>
<item name="android:textColorPrimary">#color/textColorPrimary</item>
<item name="android:textColorSecondary">#color/textColorSecondary</item>
</style>
<!-- Application theme to be used -->
<style name="AppTheme" parent="AppTheme.Base"></style>
</resources>
values-v22/styles.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="AppTheme.Base">
<item name="android:colorPrimary">#color/primaryColor</item>
<item name="android:colorPrimaryDark">#color/primaryColorDark</item>
<item name="android:colorAccent">#color/accentColor</item>
<item name="android:textColorPrimary">#color/textColorPrimary</item>
<item name="android:textColorSecondary">#color/textColorSecondary</item>
</style>
</resources>
Please note to create another folder in in res folder named values-v22.This will be used by Lollipop devices.And values/styles.xml will be used by pre-lollipop devices.

on creating styles.xml in Android Studio. How can I resolve it.
I've read numerous answers regarding changing the color of the action bar, but I can't seem to get it to work. Here's what I have:
styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
<!-- ActionBar styles -->
<style name="MyActionBar" parent="Theme.AppCompat.Light">
<item name="android:windowBackground">#color/actionBarBackground
</item>
</style>
</resources>
I've also tried
<item name="android:Background">#F33</item>
AndroidManifest.xml
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
You are changing the android:windowBackground not the background of your ActionBar.
In any case, starting with the AppCompat v21+, you can use a new way to customize your ActionBar.
All of your Activities must extend from AppCompatActivity
All of your themes (that want an ActionBar/Toolbar) must inherit from Theme.AppCompat.
Just use a theme like this:
<style name="Theme.MyTheme" parent="Theme.AppCompat.Light">
<!-- Set AppCompat’s color theming attrs -->
<item name="colorPrimary">#color/my_awesome_red</item>
<item name="colorPrimaryDark">#color/my_awesome_darker_red</item>
<!-- The rest of your attributes -->
</style>
The current version of AppCompat is 23. It requires API23 to compile the project.
The following seems to have done the trick. I found it here Change Background color of the action bar using AppCompat
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
<!-- ActionBar styles -->
<style name="MyActionBar" parent="Theme.AppCompat.Light">
<item name="android:background">#color/actionBarBackground</item>
<item name="background">#color/actionBarBackground</item>
</style>
However, now my android:label in my manifest file is being covered by the background color, so I added
<item name="android:displayOptions">showTitle</item>
<item name="displayOptions">showTitle</item>
I use ActionBar in my Application. And I customized my own actionbar theme as the android developer site puts. unfortunately, My style doesn't work anyway. Every time my app is runned, there is an IllegalStateException thrown. And the detail is "You need to use a Theme.AppCompat theme (or descendant) with this activity.". Then, my custom style is here:
<resources>
<!-- the theme applied to the application or activity -->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">#8FB01C</item>
<!-- colorPrimaryDark is used for the status bar -->
<item name="colorPrimaryDark">#CCE96B</item>
<item name="colorAccent">#303A0A</item>
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- the theme applied to the application or activity -->
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="android:actionBarTabTextStyle">#style/TabTextStyle</item>
<item name="android:actionMenuTextColor">#color/action_bar_text_color</item>
<!-- Support library compatibility -->
<item name="actionBarStyle">#style/MyActionBar</item>
<item name="actionBarTabTextStyle">#style/TabTextStyle</item>
<item name="actionMenuTextColor">#color/action_bar_text_color</item>
</style>
<!-- ActionBar theme. -->
<style name="ActionBarTheme" parent="AppTheme">
<!-- when hide or show ActionBar frequently, use this attribute. -->
<item name="windowActionBarOverlay">true</item>
</style>
<!-- general styles for the action bar -->
<style name="MyActionBar" parent="#style/Widget.AppCompat.ActionBar">
<item name="android:titleTextStyle">#style/TitleTextStyle</item>
<item name="android:background">#drawable/actionbar_background</item>
<item name="android:backgroundStacked">#drawable/actionbar_background</item>
<item name="android:backgroundSplit">#drawable/actionbar_background</item>
<!-- Support library compatibility -->
<item name="titleTextStyle">#style/TitleTextStyle</item>
<item name="background">#drawable/actionbar_background</item>
<item name="backgroundStacked">#drawable/actionbar_background</item>
<item name="backgroundSplit">#drawable/actionbar_background</item>
</style>
<!-- action bar title text -->
<style name="TitleTextStyle" parent="#style/TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textColor">#400040</item>
</style>
<!-- action bar tab text -->
<style name="TabTextStyle" parent="#style/Widget.AppCompat.ActionBar.TabText">
<item name="android:textColor">#400040</item>
</style>
</resources>
And my manifest about this activity is here:
<activity
android:name=".HomeActivity"
android:label="#string/app_name"
android:launchMode="singleInstance"
android:theme="#style/ActionBarTheme"
android:uiOptions="splitActionBarWhenNarrow" >
</activity>
But the strange thing is when I set android:theme="#style/ActionBarTheme" to android:theme="#style/Theme.Appcomat.Light", it works well. But the style is not what I want. So, it does confuse me. So, I want to know why my custom style doesn't work.
Alright, After the ActionBarTheme is changed into this:
<style name="ActionBarTheme" parent="#style/Theme.AppCompat.Light">
<item name="colorPrimary">#8FB01C</item>
<item name="colorPrimaryDark">#CCE96B</item>
<item name="colorAccent">#4D4DFF</item>
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="android:actionBarTabTextStyle">#style/TabTextStyle</item>
<item name="android:actionMenuTextColor">#color/action_bar_text_color</item>
<item name="actionBarStyle">#style/MyActionBar</item>
<item name="actionBarTabTextStyle">#style/TabTextStyle</item>
<item name="actionMenuTextColor">#color/action_bar_text_color</item>
<item name="windowActionBarOverlay">true</item>
</style>
it works well. Yep, here:
<style name="ActionBarTheme" parent="AppTheme">
It doesn't work. So I want to know why. Can't custom style be inherited, something wrong with my dev environment, or something else?
Maybe this is just the problem of your IDE. If you are using Eclipse, project-->clean, and then select your project, OK, then your project will rebuild. If you are using Android Studio, then, Build-->Rebuild Project or Clean Project, then take a look at the result.
So I have a spinner and I was successful in changing the color of the selected item but I am not able to change the color of the items in the drop down menu
This is my spinner_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="13sp"
android:textColor="#33CCFF"
/>
and this is my styles.xml
<resources>
<style name="AppTheme" parent="android:Theme.Light" >
<item name="android:spinnerDropDownItemStyle">#style/SpinnerItem.DropDownItem.Color</item>
<item name="android:spinnerItemStyle">#style/SpinnerItem</item>
</style>
<style name="SpinnerItem.DropDownItem.Color" parent="#android:style/Widget.DropDownItem.Spinner">
<item name="android:textColor">#4FBDE8</item>
</style>
<style name="SpinnerItem" parent="#android:style/Widget.TextView.SpinnerItem">
<item name="android:textColor">#4FBDE8</item>
</style>
</resources>
is there an XML way I can do it in ?
Here is the solution I found on another stackoverflow thread
<style name="Theme.NoTitleBar.WithColoredSpinners" parent="#android:style/Theme.NoTitleBar">
<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">#00FF00</item>
</style>
<style name="SpinnerItem.DropDownItem" parent="#android:style/Widget.DropDownItem.Spinner">
<item name="android:textColor">#FF0000</item>
</style>
While specifying a layout resource file for the spinner, you have to set it at two places.
While declaring a new ArrayAdapter
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, R.layout.spinner_item, categories);
While setting the dropDownViewResource on the array adapter.
dataAdapter.setDropDownViewResource(R.layout.spinner_item_dropdown);
Notice that two different layout files have been used. You can customize your views in the following manner, by defining the styles and using these styles as theme in the respective layouts.
<style name="SpinnerItem" parent="#android:style/Widget.TextView.SpinnerItem">
<item name="android:textColor">#color/white</item>
<item name="android:background">#color/black</item>
</style>
<style name="SpinnerItem.DropDownItem" parent="#android:style/Widget.DropDownItem.Spinner">
<item name="android:textColor">#color/black</item>
</style>
Hope this helps.
