Change ActionBar Tabs background color

Question

Is there a way to change the background color of the tab bar in the ActionBar without changing it in the one line version?

To clarify what I want: In portrait mode the ActionBar is split in two lines, the ActionBar itself and the tabs below. In landscape mode the tabs are in the actual ActionBar.

I want to change the background color of the portrait mode. If I change the background in the TabView it'll be changed for both modes. Do I have to create separate styles for those? Which brings up a second question: is there a way to know when it'll be two lines and when not?

Or am I just missing something?

I'm using ActionBarSherlock btw

Answer 1

To seperate styles depending on orientation you have to create in your /res folder a new folder called layout-land (for landscape mode) and layout-port (in portrait mode) and put your xml files for action bar and set it's specific style (with the color you want) on each folder.

To Change Actionbar Tab's color, Pls use this code:

//For Example if you want White color as Tabs background, then

getActionBar().setStackedBackgroundDrawable(new ColorDrawable(Color.parseColor("#FFFFFF")));

Answer 3

In ActionBarSherlock's values/abs__themes.xml there is

<item name="actionModeSplitBackground">@drawable/abs__cab_background_bottom_holo_dark</item>

You have to create your own theme derived from ABS

<style name="AppTheme" parent="Theme.Sherlock">
    <item name="actionBarStyle">@style/MyActionBar</item>
    <item name="android:actionBarStyle">@style/MyActionBar</item>
</style>

<style name="MyActionBar" parent="Widget.Sherlock.ActionBar">
    <item name="actionModeSplitBackground">@drawable/my_split_background</item>
</style>

Hope this helps you.

I think you are looking for the android:backgroundStacked attribute of the ActionBar style:

<style name="MyTheme" parent="android:Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/MyActionBarStyle</item>
</style>

<style name="MyActionBarStyle" parent="@android:style/Widget.Holo.Light.ActionBar.Solid">
    <item name="android:backgroundStacked">@drawable/my_stacked_background</item>
</style>

or (If using ActionBarSherlock):

<style name="MyTheme" parent="@style/Theme.Sherlock.Light">
    <item name="android:actionBarStyle">@style/MyActionBarStyle</item>
    <item name="actionBarStyle">@style/MyActionBarStyle</item>
</style>

<style name="MyActionBarStyle" parent="@style/Widget.Sherlock.Light.ActionBar.Solid">
    <item name="android:backgroundStacked">@drawable/my_stacked_background</item>
    <item name="backgroundStacked">@drawable/my_stacked_background</item>
</style>

Answer 5

ColorDrawable colorDrawable = new ColorDrawable(Color.White);
actionBar.SetStackedBackgroundDrawable(colorDrawable);

for xamarin folks.
