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
anybody have any idea about this behavior?
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" />

</selector>
I've a TabWidget, independently of the ÀctionBar, in aFragmentTabHost`.
I want to customize the look and feel of the TabWidget but I don't get it. My intention is to change the text color and the selector color, as you can see in the image I can change the background of the TabWidget. I don't want to use a custom TextViewfor the tabs because the tabs must be with the Holo look and feel.
I've tried to put a style to the TabWidgetbut it doesn't work. In this way:
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
style="#style/MyTabs"
/>
and with the style
<style name="MyTabs">
<item name="android:textColor">#color/white</item>
<item name="android:background">#drawable/tabs</item>
<item name="android:backgroundStacked">#color/red_action_bar</item>
</style>
I've tried to add the style from a theme.xml using theparent="android:Widget.Holo.TabWidget", but nothing happens.
I finally find a way to do that. Using this code in the onCreateViewmethod of the Fragment
for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
View v = tabHost.getTabWidget().getChildAt(i);
v.setBackgroundResource(R.drawable.tabs);
TextView tv = (TextView) tabHost.getTabWidget().getChildAt(i).findViewById(android.R.id.title);
tv.setTextColor(getResources().getColor(R.color.white));
}
And setting the bakcground color of the TabWidgetto red
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...
Try this:
1.Create a new style:
<style name="TabText">
<item name="android:textColor">#color/YOUR_COLOR</item>
</style>
2.On Tab Host, set theme:
<TabHost android:theme="#style/TabText">
3.The background you can set normally on TabWidget
<TabWidget android:background="#FFF"/>
As I answered here, this can actually be done using XML themes. The TabWidget uses android:textPrimaryColor for the selected tab and android:textSecondaryColor for the unselected ones. The accent color is determined by colorAccent and the background color by colorPrimary Thus, you can achieve the desired customization like this:
In styles.xml:
<style name="TabWidgetTheme" parent="AppTheme">
<item name="colorPrimary">#color/your_primary_color</item>
<item name="colorAccent">#color/your_accent_color</item>
<item name="android:textPrimaryColor">#color/your_primary_color</item>
<item name="android:textSecondaryColor">#color/your_secondary_color</item>
</style>
In your layout:
<TabHost
android:layout_height="match_parent"
android:layout_width="match_parent"
android:theme="#style/TabWidgetTheme"/>
Note that the android:theme should not be directly in the TabWidget itself, but rather the containing TabHost or similar.
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.
