I have an activity with action bar and action bar tabs. I am using appcompat for action bar. I have attached the screen shots. on emulator 4.4 and htc 4.1.1 tabs widths id correct but on nexus 4, 4.4 it adds some margin due to which it looks ugly.
Edit
how i am adding tabs.
ActionBar ab = getSupportActionBar();
ab.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ab.setTitle("Purchase media");
ab.setSubtitle("To share with members");
ab.addTab(ab.newTab().setText("Audios").setTabListener(this));
ab.addTab(ab.newTab().setText("Videos").setTabListener(this));
my style for tabs is as follow
<style name="ActionBarTabStyle.Example" parent="#style/Widget.AppCompat.ActionBar.TabView">
<item name="android:background">#drawable/tab_indicator_ab_example</item>
</style>
and tab indicator selector is as follow
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="#android:color/transparent" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_selected_example" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/tab_unselected_focused_example" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_selected_focused_example" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="#drawable/tab_unselected_pressed_example" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:drawable="#drawable/tab_selected_pressed_example" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="#drawable/tab_unselected_pressed_example" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="#drawable/tab_selected_pressed_example" />
how it looks.
how it should be

The traditional way to implement ActionBar tabs has now been deprecated. So I have now implemented my tabs with this guide github tabs.
However I have a problem with styling the tabs with this guide. It seems you can only style the tabs through java code like this:
slidingTabLayout
.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
#Override
public int getIndicatorColor(int position) {
return Color.RED;
}
});
This will only change the color of the indicator, but I want to change the background of the tabs in both selected, deselected and pressed states. The tradional way was to change the theme and make a XML file like this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- STATES WHEN BUTTON IS NOT PRESSED -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false"
android:state_pressed="false"
android:drawable="#drawable/tab_unselected" />
<item android:state_focused="false" android:state_selected="true"
android:state_pressed="false"
android:drawable="#drawable/tab_selected" />
<!-- Focused states (such as when focused with a d-pad or mouse hover) -->
<item android:state_focused="true" android:state_selected="false"
android:state_pressed="false"
android:drawable="#drawable/tab_unselected_focused" />
<item android:state_focused="true" android:state_selected="true"
android:state_pressed="false"
android:drawable="#drawable/tab_selected_focused" />
<!-- STATES WHEN BUTTON IS PRESSED -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false"
android:state_pressed="true"
android:drawable="#drawable/tab_unselected_pressed" />
<item android:state_focused="false" android:state_selected="true"
android:state_pressed="true"
android:drawable="#drawable/tab_selected_pressed" />
<!-- Focused states (such as when focused with a d-pad or mouse hover) -->
<item android:state_focused="true" android:state_selected="false"
android:state_pressed="true"
android:drawable="#drawable/tab_unselected_pressed" />
<item android:state_focused="true" android:state_selected="true"
android:state_pressed="true"
android:drawable="#drawable/tab_selected_pressed" />
</selector>
How can I do the same with the new way of doing tabs without having to install 3rd party librarys like this github?
I'm trying to create a custom Tabs. I implemented the indicator color with 9.png with Android Action Bar Style Generator. But now I want to change the background color for each Tab programmatically. How I can do? Thank you.
JAVA
TabWidget tw = (TabWidget)tabs.findViewById(android.R.id.tabs);
View tabView = tw.getChildTabViewAt(0);
tabView.setBackgroundResource(R.drawable.tab_indicator_blanco);
View tabView2 = tw.getChildTabViewAt(1);
tabView2.setBackgroundResource(R.drawable.tab_indicator_blanco);
tab_indicator_blanco.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/tab_unselected_blanco" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_selected_blanco" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/tab_unselected_focused_blanco" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_selected_focused_blanco" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="#drawable/tab_unselected_pressed_blanco" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:drawable="#drawable/tab_selected_pressed_blanco" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="#drawable/tab_unselected_pressed_blanco" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="#drawable/tab_selected_pressed_blanco" />
</selector>
So I just want to change the blue line color of tab widget in the app. I searched online and the found solutions to changing the whole background of the tabs but i just want to change the blue line color of the tab widget to another color like black. Can that be done?
You can try this style:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false"
android:state_selected="false"
android:state_pressed="false"
android:drawable="#drawable/tab_unselected_holo" />
<item android:state_focused="false"
android:state_selected="true"
android:state_pressed="false"
android:drawable="#drawable/tab_selected_holo" />
<!-- Focused states -->
<item android:state_focused="true"
android:state_selected="false"
android:state_pressed="false"
android:drawable="#drawable/tab_unselected_focused_holo" />
<item android:state_focused="true"
android:state_selected="true"
android:state_pressed="false"
android:drawable="#drawable/tab_selected_focused_holo" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false"
android:state_selected="false"
android:state_pressed="true"
android:drawable="#drawable/tab_unselected_pressed_holo" />
<item android:state_focused="false"
android:state_selected="true"
android:state_pressed="true"
android:drawable="#drawable/tab_selected_pressed_holo" />
<!-- Focused states -->
<item android:state_focused="true"
android:state_selected="false"
android:state_pressed="true"
android:drawable="#drawable/tab_unselected_pressed_holo" />
<item android:state_focused="true"
android:state_selected="true"
android:state_pressed="true"
android:drawable="#drawable/tab_selected_pressed_holo" />
</selector>

Hope it will help you.
Make a separate Style for your tabwidget in your custom theme.
Try out as below:
<item name="android:tabWidgetStyle">#android:style/Widget.TabWidget</item>
and
<style name="Widget.TabWidget">
<item name="android:textAppearance">#style/TextAppearance.Widget.TabWidget</item>
<item name="android:ellipsize">marquee</item>
<item name="android:singleLine">true</item>
</style>
<style name="TextAppearance.Widget.TabWidget">
<item name="android:textSize">14sp</item>
<item name="android:textStyle">normal</item>
<item name="android:textColor">#android:color/tab_indicator_text</item>
</style>
I hope this will be helpfull to you.
How can I change the colour of the line that appears under the highlighted Action Bar Sherlocks tab.
It's default is an electric blue.
Here an implementation based on the google i/o app implementation:
Set the theme style:
<style name="Theme.Styled" parent="Theme.Sherlock.Light">
<item name="android:actionBarTabBarStyle">#style/Widget.Styled.TabBar</item>
<item name="actionBarTabBarStyle">#style/Widget.Styled.TabBar</item>
</style>
<style name="Widget.Styled.TabView" parent="Widget.Sherlock.Light.ActionBar.TabView">
<item name="android:background">#drawable/tab_white_ab</item>
</style>
Create a drawable like this - notice that in the google I/O app the non focused state is transparent - in the example below I changed transparent to green:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false"
android:state_selected="false"
android:state_pressed="false"
android:drawable="#drawable/tab_green_unselected"
/>
<!-- android:drawable="#android:color/transparent"-->
<item android:state_focused="false"
android:state_selected="true"
android:state_pressed="false"
android:drawable="#drawable/tab_white_selected" />
<!-- Focused states -->
<item android:state_focused="true"
android:state_selected="false"
android:state_pressed="false"
android:drawable="#drawable/item_focused" />
<item android:state_focused="true"
android:state_selected="true"
android:state_pressed="false"
android:drawable="#drawable/tab_white_selected_focused" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false"
android:state_selected="false"
android:state_pressed="true"
android:drawable="#drawable/item_pressed" />
<item android:state_focused="false"
android:state_selected="true"
android:state_pressed="true"
android:drawable="#drawable/tab_white_selected_pressed" />
<!-- Focused states -->
<item android:state_focused="true"
android:state_selected="false"
android:state_pressed="true"
android:drawable="#drawable/item_focused" />
<item android:state_focused="true"
android:state_selected="true"
android:state_pressed="true"
android:drawable="#drawable/tab_white_selected_pressed" />
Hope this helps.
I have an ActionBar in an app, and it has navigation tabs embedded in it (not TabHost!). By default the tabs show as dark grey, with a thin blue line under all the tabs, and a blue marker on the selected tab.
Which styles do I override to change those colours?
I have not changed the tabs themselves, but I would assume that you can do it with these styles from styles.xml...
<style name="Widget.Holo.TabWidget" parent="Widget.TabWidget">
<item name="android:tabStripLeft">#null</item>
<item name="android:tabStripRight">#null</item>
<item name="android:tabStripEnabled">false</item>
<item name="android:divider">?android:attr/dividerVertical</item>
<item name="android:showDividers">middle</item>
<item name="android:dividerPadding">8dip</item>
<item name="android:measureWithLargestChild">true</item>
<item name="android:tabLayout">#android:layout/tab_indicator_holo</item>
</style>
with tab_indicator_holo.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/tab_unselected_holo" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_selected_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/tab_unselected_focused_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_selected_focused_holo" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="#drawable/tab_unselected_pressed_holo" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:drawable="#drawable/tab_selected_pressed_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="#drawable/tab_unselected_pressed_focused_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="#drawable/tab_selected_pressed_focused_holo" />
</selector>
Or you may also try
<style name="Widget.Holo.ActionBar.TabView" parent="Widget.ActionBar.TabView">
<item name="android:background">#drawable/tab_indicator_ab_holo</item>
<item name="android:paddingLeft">16dip</item>
<item name="android:paddingRight">16dip</item>
</style>
and tab_indicator_ab_holo.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="#color/transparent" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_selected_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/list_focused_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/tab_selected_focused_holo" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="#drawable/list_pressed_holo_dark" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:drawable="#drawable/tab_selected_pressed_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="#drawable/tab_unselected_pressed_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="#drawable/tab_selected_pressed_holo" />
</selector>
Finally using the two png-9 drawables: tab_selected_holo and tab_unselected_holo. They look like the two thicker and thinner blue lines you are talking about.
Or do you mean the minitabs?
<style name="Widget.ActionBar.TabView" parent="Widget">
<item name="android:gravity">center_horizontal</item>
<item name="android:background">#drawable/minitab_lt</item>
<item name="android:paddingLeft">4dip</item>
<item name="android:paddingRight">4dip</item>
</style>
with in minitab_lt.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:state_selected="true"
android:drawable="#drawable/minitab_lt_press" />
<item android:state_selected="true"
android:drawable="#drawable/minitab_lt_selected" />
<item android:state_pressed="true"
android:drawable="#drawable/minitab_lt_unselected_press" />
<item android:drawable="#drawable/minitab_lt_unselected" />
</selector>
If you need another definition just search for TabWidget in here: https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/styles.xml
Then as usual define your own style with all the required attributes and drawables...
If you want to customize easily your tab bars, you can use this great tool :
http://jgilfelt.github.io/android-actionbarstylegenerator
You just select the colors you want and it automatically generates the style XMLs, the PNGs, etc.
