Transparent Actiobar in android - android

I am trying to give transparent effect to my action bar. I have used the following line to make it work that way, but strangely on my Nexus 5 I am can see the bar coming, but on my galaxy nexus I don't see it at all.
I am not sure why this is coming up on N5? How to solve this issue?
Here is the code:
getWindow().requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setDisplayShowHomeEnabled(false);
ActionBar actionBar = getActionBar();
actionBar.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
actionBar.setStackedBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
setContentView(R.layout.profile);
Here is the screenshot for both Galaxy nexus running Jelly Bean (4.3) and Nexus 5 running kitkat (4.4.4)
Galaxy Nexus: showing transparent action bar perfectly:
Nexus 5: showing transparent action bar: (A horizontal line is shown)
Update 2:
I managed to remove the line on N5 by using the following style
styles.xml in Values-v14 folder
<style name="AppBaseTheme" parent="android:Theme.Holo.Light.DarkActionBar"></style>
<style name="CustomActionBarTheme" parent="#android:style/Theme.Holo"></style>
then added theme to specific activity in manifext:
<activity
android:name=".Profile"
android:label="#string/profile"
android:theme="#style/CustomActionBarTheme"
android:screenOrientation="portrait" >
but then all my text, dialog format have changed in this activity. It has become dark. It doesn't change even though I programatically change the theme for dialog. I am not sure what is wrong? Can someone help me out with this?
Update 1: As per #erakitn advice: I tried the following with few changes:
<!-- Transparent ActionBar Style -->
<style name="CustomThemeTransparent" parent="AppBaseTheme">
<item name="android:background">#android:color/transparent</item>
<item name="background">#android:color/transparent</item>
</style>
<!-- Activity Theme with transparent ActionBar -->
<style name="CustomThemeTransparentLight" parent="AppBaseTheme">
<item name="android:actionBarStyle">#style/CustomThemeTransparent</item>
<item name="actionBarStyle">#style/CustomThemeTransparent</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:backgroundDimEnabled">false</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="windowActionBarOverlay">true</item>
</style>
I have getting the following error:
1. error: Error: No resource found that matches the given name: attr 'background'.
2. error: Error: No resource found that matches the given name: attr 'actionBarStyle'.
3. error: Error: No resource found that matches the given name: attr 'windowActionBarOverlay'.


To remove ActionBar shadow try to add <item name="android:windowContentOverlay">#null</item> attribute to your Activity theme. Below there is an example of theme with transparent ActionBar. Define it in res/styles.xml:
<!-- Your App Theme-->
<style name="YourAppTheme.Light" parent="#style/Theme.AppCompat.Light">
<...>
</style>
<!-- Transparent ActionBar Style -->
<style name="YourAppTheme.Light.ActionBar.Transparent" parent="#style/Widget.AppCompat.Light.ActionBar">
<item name="android:background">#android:color/transparent</item>
<item name="background">#android:color/transparent</item>
</style>
<!-- Activity Theme with transparent ActionBar -->
<style name="YourAppTheme.TransparentActionBar.Light" parent="#style/YourAppTheme.Light">
<item name="android:actionBarStyle">#style/YourAppTheme.Light.ActionBar.Transparent</item>
<item name="actionBarStyle">#style/YourAppTheme.Light.ActionBar.Transparent</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:backgroundDimEnabled">false</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="windowActionBarOverlay">true</item>
</style>
And set this theme to your Activity:
<activity
android:name="your.package.name.YourActivity"
android:label="#string/app_name"
android:theme="#style/YourAppTheme.TransparentActionBar.Light" />
UPD:
If you are not using AppCompat or ABS you should use HOLO theme as parent for your theme. It seems you use light theme with dark ActionBar. Please try following solution:
<!-- Your App Theme-->
<style name="YourAppTheme.Light" parent="#android:style/Theme.Holo.Light.DarkActionBar">
<...>
</style>
<!-- Transparent ActionBar Style -->
<style name="YourAppTheme.Light.ActionBar.Transparent" parent="#android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
<item name="android:background">#android:color/transparent</item>
</style>
<!-- Activity Theme with transparent ActionBar -->
<style name="YourAppTheme.TransparentActionBar.Light" parent="#style/YourAppTheme.Light">
<item name="android:actionBarStyle">#style/YourAppTheme.Light.ActionBar.Transparent</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:backgroundDimEnabled">false</item>
<item name="android:windowActionBarOverlay">true</item>
</style>


Please don't change anything
Your original code is just fine. All you need to do is set/apply the following attribute:
android:windowContentOverlay = true
Again, don't change your theme/style. Define a new one like this:
<style name="ConOver" > <<== no parent
<item name="android:windowContentOverlay">#null</item>
</style>
Add this above your code:
// Add this line
// Lets you add new attribute values into the current theme
getTheme().applyStyle(R.style.ConOver, true);
// Rest stays the same
getWindow().requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setDisplayShowHomeEnabled(false);
ActionBar actionBar = getActionBar();
actionBar.setBackgroundDrawable(new
ColorDrawable(android.graphics.Color.TRANSPARENT));
actionBar.setStackedBackgroundDrawable(new
ColorDrawable(android.graphics.Color.TRANSPARENT));
setContentView(R.layout.profile);


Since you are using DarkActionBar as a theme now the dialog will turn black all around because that is the style DarkActionBar is using.
You can style your dialog from default light theme of HOLO for dialogs.
sample:
final AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, android.R.style.Theme_Holo_Light_Dialog));
EDIT:
Change this:
<style name="CustomActionBarTheme" parent="#android:style/Theme.Holo"></style>
To
<style name="CustomActionBarTheme" parent="#android:style/Theme.Holo.Light"></style>

Why isn't the action bar text color changing?

I am on android lollipop and using the following style as my theme MyNavigationDrawerTheme
in styles v14
<style name="MyNavigationDrawerTheme" parent="MaterialNavigationDrawerTheme.Light">
<item name="actionMenuTextColor">#color/white</item>
</style>
in material drawer theme.xml (mostly irrelevant to this issue)
<style name="MaterialNavigationDrawerTheme.Light" parent="Theme.AppCompat.Light.NoActionBar" >
<item name="drawerType">#integer/DRAWERTYPE_ACCOUNTS</item>
<item name="drawerColor">#fafafa</item>
</style>
I understand that the theme Theme.AppCompat.Light.NoActionBar has black text for the action bar but why isn't it changing when I include the line
<item name="actionMenuTextColor">#color/white</item>
I have been trying to fix this for almost two days now tried so many things (eg here) but nothing works
Any idea

you could try this in styles.xml:
<style name="MyNavigationDrawerTheme" parent="MaterialNavigationDrawerTheme.Light">
<item name="android:actionMenuTextColor">#color/white</item>
<item name="android:actionMenuTextAppearance">#style/TextAppearance.ActionMenu
</item>
</style>
<style name="TextAppearance.ActionMenu">
<item name="android:textColor">#color/white</item>
</style>
ps:
yeah ,sometimes it won't works only by android:actionMenuTextColor ,such as Galaxy S4
just add attr android:actionMenuTextAppearance

In case you are using Toolbar, this is how you do it -
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:textColorPrimary">#android:color/holo_red_dark</item>
<item name="textColorPrimary">#android:color/holo_red_dark</item>
<!-- Customize your theme here. -->
</style>
Should work like a charm :)

Action bar with custom background not shown

I am trying to change the background of the action bar via xml, but the action bar is not shown anymore at all.
This is the style that I am using, declared in styles.xml:
<style name="AppBaseTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<item name="actionBarStyle">#style/DiaryActionBar</item>
<item name="android:actionBarStyle">#style/DiaryActionBar</item>
</style>
<style name="DiaryActionBar"
parent="#style/Theme.AppCompat.Light.DarkActionBar">
<item name="background">#color/action_bar_bg</item>
<item name="android:background">#color/action_bar_bg</item>
</style>
I have set both android:background and background for compatibility. This is the only styles.xml file in my app. What am I doing wrong?

In my style with custom actionbar background, i have this:
<style name="Theme.Malaka" parent="#style/Theme.AppCompat">
<style name="Malaka.ActionBar" parent="#style/Widget.AppCompat.ActionBar">
And that works just fine. Items of the styles are the same as yours. Please note that the parent of Malaka.ActionBar is not Theme... but Widget...

For changing background and actionBarStyle from android styling.You can do like this..
<style name="AppBaseTheme" parent="#android:style/Theme.Black">
<item name="android:actionBarStyle">#style/Theme.DeviceDefault.NoActionBar</item>
</style>
<style name="DiaryActionBar" parent="#android:style/Theme.Black">
<item name="android:background">#color/action_bar_bg</item>
</style>

Actionbar (android.support.v7) fills the entire screen

I have given a custom theme, different style.xml for API levels "7-13" and "14 and above"
<style name="CustomTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<!-- Setting values in the default namespace affects API levels 7-13 -->
<item name="actionBarStyle">#style/CustomTheme</item>
</style>
<style name="CustomTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<!-- Setting values in the default namespace affects API levels 7-13 -->
<item name="background">#color/medium_turquoise</item>
</style>
<style name="CustomTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<item name="actionBarSize">200dp</item>
</style>
<style name="CustomTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<item name="homeAsUpIndicator">#drawable/back_button_actionbar</item>
I have set the theme of my application as "#style/CustomTheme" and in my activity i have set following.
addView = getLayoutInflater().inflate(R.layout.actionbar, null);
getSupportActionBar().setCustomView(addView);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
The entire screen has been taken by the action bar, I tried to change the height but of no use. I guess I am doing some mistake with the style.
Thanks

Your code seems to be perfectly fine to me. Maybe Genymotion is not rendering it properly. Try running it on actual device or emulator in sdk.
Also one suggestion, if you are making a custom theme in android then try to avoid defining same style attribute again. see below
<style name="CustomTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<!-- Setting values in the default namespace affects API levels 7-13 -->
<item name="actionBarStyle">#style/CustomTheme</item>
<item name="background">#color/medium_turquoise</item>
<item name="actionBarSize">200dp</item>
<item name="homeAsUpIndicator">#drawable/back_button_actionbar</item>
</style>

How to set custom ActionBar color / style?

I am using Android Navigation bar in my project,
I want to change the top color in action bar to something red, How can i do that?
I have something like this,
and i want something like this,
how can i achieve that?

You can define the color of the ActionBar (and other stuff) by creating a custom Style:
Simply edit the res/values/styles.xml file of your Android project.
For example like this:
<resources>
<style name="MyCustomTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">#style/MyActionBarTheme</item>
</style>
<style name="MyActionBarTheme" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">ANY_HEX_COLOR_CODE</item>
</style>
</resources>
Then set "MyCustomTheme" as the Theme of your Activity that contains the ActionBar.
You can also set a color for the ActionBar like this:
ActionBar actionBar = getActionBar();
actionBar.setBackgroundDrawable(new ColorDrawable(Color.RED)); // set your desired color
Taken from here: How do I change the background color of the ActionBar of an ActionBarActivity using XML?

In general Android OS leverages a “theme” to allow app developers to globally apply a universal set of UI element styling parameters to Android applications as a whole, or, alternatively, to a single Activity subclass.
So there are three mainstream Android OS “system themes,” which you can specify in your Android Manifest XML file when you are developing apps for Version 3.0 and later versions
I am referring the (APPCOMPAT)support library here:--
So the three themes are
1. AppCompat Light Theme (Theme.AppCompat.Light)
AppCompat Dark Theme(Theme.AppCompat),
And a hybrid between these two ,AppCompat Light Theme with the Darker ActionBar.( Theme.AppCompat.Light.DarkActionBar)
AndroidManifest.xml and see the tag, the android theme is mentioned as:-- android:theme="#style/AppTheme"
Open the Styles.xml and we have base application theme declared there:--
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
</style>
We need to override these parent theme elements to style the action bar.
ActionBar with different color background:--
To do this we need to create a new style MyActionBar(you can give any name) with a parent reference to #style/Widget.AppCompat.Light.ActionBar.Solid.Inverse that holds the style characteristics for the Android ActionBar UI element. So definition would be
<style name="MyActionBar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="background">#color/red</item>
</style>
And this definition we need to reference in our AppTheme, pointing to overridden ActionBar styling as--
#style/MyActionBar
Change the title bar text color (e.g black to white):--
Now to change the title text color, we need to override the parent reference parent="#style/TextAppearance.AppCompat.Widget.ActionBar.Title">
So the style definition would be
<style name="MyActionBarTitle" parent="#style/TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textColor">#color/white</item>
</style>
We’ll reference this style definition inside the MyActionBar style definition, since the TitleTextStyle modification is a child element of an ActionBar parent OS UI element. So the final definition of MyActionBar style element will be
<style name="MyActionBar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="background">#color/red</item>
<item name="titleTextStyle">#style/MyActionBarTitle</item>
</style>
SO this is the final Styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<!-- This is the styling for action bar -->
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
<style name="MyActionBar" parent="#style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="background">#color/red</item>
<item name="titleTextStyle">#style/MyActionBarTitle</item>
</style>
<style name="MyActionBarTitle" parent="#style/TextAppearance.AppCompat.Widget.ActionBar.Title">
<item name="android:textColor">#color/white</item>
</style>
</resources>
For further ActionBar options Menu styling, refer this link

For Android 3.0 and higher only
When supporting Android 3.0 and higher only, you can define the action bar's background like this:
res/values/themes.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- the theme applied to the application or activity -->
<style name="CustomActionBarTheme" parent="#style/Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
<!-- ActionBar styles -->
<style name="MyActionBar" parent="#style/Widget.Holo.Light.ActionBar.Solid.Inverse">
<item name="android:background">#ff0000</item>
</style>
</resources>
For Android 2.1 and higher
When using the Support Library, your style XML file might look like this:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- the theme applied to the application or activity -->
<style name="CustomActionBarTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/MyActionBar</item>
<!-- 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">#drawable/actionbar_background</item>
<!-- Support library compatibility -->
<item name="background">#drawable/actionbar_background</item>
</style>
</resources>
Then apply your theme to your entire app or individual activities:
for more details Documentaion

You can change action bar color on this way:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/green_action_bar</item>
</style>
Thats all you need for changing action bar color.
Plus if you want to change the status bar color just add the line:
<item name="android:colorPrimaryDark">#color/green_dark_action_bar</item>
Here is a screenshot taken from developer android site to make it more clear, and here is a link to read more about customizing the color palete

Another possibility of making.
actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#0000ff")));

I can change ActionBar text color by using titleTextColor
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="titleTextColor">#333333</item>
</style>

Custom Color:
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">#color/ColorPrimary</item>
<item name="colorPrimaryDark">#color/ColorPrimaryDark</item>
<!-- Customize your theme here. -->
</style>
Custom Style:
<style name="Theme.AndroidDevelopers" parent="android:style/Theme.Holo.Light">
<item name="android:selectableItemBackground">#drawable/ad_selectable_background</item>
<item name="android:popupMenuStyle">#style/MyPopupMenu</item>
<item name="android:dropDownListViewStyle">#style/MyDropDownListView</item>
<item name="android:actionBarTabStyle">#style/MyActionBarTabStyle</item>
<item name="android:actionDropDownStyle">#style/MyDropDownNav</item>
<item name="android:listChoiceIndicatorMultiple">#drawable/ad_btn_check_holo_light</item>
<item name="android:listChoiceIndicatorSingle">#drawable/ad_btn_radio_holo_light</item>
</style>
For More: Android ActionBar

As I was using AppCompatActivity above answers didn't worked for me. But the below solution worked:
In res/styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
</style>
PS: I've used colorPrimary instead of android:colorPrimary

in the style.xml add this code
<resources>
<style name="MyTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">#style/MyAction</item>
</style>
<style name="MyActionBarTheme" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">#333333</item>
</style>
</resources>

Actionbar Sherlock title shows for a sec at first run

As i mentioned in title of question I want to completely remove title from actionbar but at first run (when I run it from eclipse) title shows for a while and it's not what I want
in the onCreate method I've add this 2 line of code and its work but LATE!!
getSupportActionBar().setTitle("");
getSupportActionBar().setDisplayShowTitleEnabled(false);
may this 2 pics help u understand me

Set your theme to 'no action bar' in your manifest, then apply your normal theme in code after set contentview!
android:theme="#style/Theme.Sherlock.Light.NoActionBar"
and then.
this.setTheme(R.style.myTheme);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

While your code hides actionBar Title, the title will still be displayed while your activity is loading and before you remove the title in your code.
I think a better solution if you want to remove title from actionbar in all of your activities from the start is to do it by setting a theme and override the actionbar style.
To do this you have to create a style in your styles.xml and use this as your application theme e.g.
<style name="AppTheme" parent="Theme.Sherlock.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/AppTheme.ActionBarStyle</item
<item name="actionBarStyle">#style/AppTheme.ActionBarStyle</item>
</style>
<style name="AppTheme.ActionBarStyle" parent="Widget.Sherlock.Light.ActionBar.Solid.Inverse">
<item name="android:titleTextStyle">#style/AppTheme.ActionBarStyle.TitleTextStyle</item>
<item name="titleTextStyle">#style/AppTheme.ActionBarStyle.TitleTextStyle</item>
</style>
<style name="AppTheme.ActionBarStyle.TitleTextStyle" parent="TextAppearance.Sherlock.Widget.ActionBar.Title">
<item name="android:textSize">0dp</item>
<item name="textSize">0sp</item>
<item name="android:textColor">#00000000</item>
<item name="textColor">#00000000</item>
</style>
or another example:
<style name="AppTheme" parent="Theme.Sherlock.Light.DarkActionBar">
<item name="android:actionBarStyle" tools:ignore="NewApi">#style/AppTheme.ActionBarStyle</item>
<item name="actionBarStyle">#style/AppTheme.ActionBarStyle</item>
</style>
<style name="AppTheme.ActionBarStyle" parent="Widget.Sherlock.Light.ActionBar.Solid.Inverse">
<item name="android:displayOptions" tools:ignore="NewApi">useLogo|showHome</item>
<item name="displayOptions">useLogo|showHome</item>
</style>
These Code samples were taken from some of my projects where i use actionbarsherlock so you may have to edit it according to your needs.
Hope it helps.
