I'm a newbie in Android development. I'm following the tutorial on this page, and trying to get an actionbar with tabs. http://developer.android.com/training/basics/actionbar/styling.html
My code seems to be exactly same as the sample in the page, except for the "android:drawable" in actionbar_tab_indicator.xml.
I used #color/blablabla rather than the #drawable/blablabla in the sample in that web page. But based on my knowledge, #color and #drawable are replaceable of each other.
Yet, I'm not getting any tab when I run the application. Only an activity with an actionbar. And the whole background is black(blank?).
Here is my themes.xml
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<!-- the theme applied to the application or activity -->
<style name="TabTheme" parent="#style/Theme.AppCompat">
<item name="android:actionBarTabStyle">#style/MyActionBarTabs</item>
<!-- android support library compatibility -->
<item name="actionBarTabStyle">#style/MyActionBarTabs</item>
</style>
<!-- ActionBar tabs styles -->
<style name="MyActionBarTabs"
parent="#style/Widget.AppCompat.ActionBar.TabView">
<!-- tab indicator -->
<item name="android:background">#drawable/actionbar_tab_indicator</item>
<!-- Support library compatibility -->
<item name="background">#drawable/actionbar_tab_indicator</item>
</style>
</resources>
And here is my actionbar_tab_indicator.xml
<?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="#color/gold" />
<item android:state_focused="false" android:state_selected="true"
android:state_pressed="false"
android:drawable="#color/articlecolor" />
<!-- 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="#color/gold" />
<item android:state_focused="true" android:state_selected="true"
android:state_pressed="false"
android:drawable="#color/articlecolor" />
<!-- STATES WHEN BUTTON IS PRESSED -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false"
android:state_pressed="true"
android:drawable="#color/black" />
<item android:state_focused="false" android:state_selected="true"
android:state_pressed="true"
android:drawable="#color/blue" />
<!-- 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="#color/black" />
<item android:state_focused="true" android:state_selected="true"
android:state_pressed="true"
android:drawable="#color/blue" />
</selector >
I'm so confused; any help is appreciated. I'm using support compat library by the way
use android:background="#drawable/actionbar_tab_indicator" to set the background color of the xml.
Also to use your theme, make sure you set android:theme="#style/TabTheme"

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'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 am having great difficultly styling tab widgets using xml. Everywhere I have searched seem's to either suggest solutions to do this programmatically, or refers to the actionBarTab style >:|
What I am trying to achieve is a customised tab from the tabwidget drawables that was generated using http://android-holo-colors.com/
I manage to get the
So in my custom theme I have this code:
<style name="RR.App.Theme" parent="android:Theme.Holo.Light">
...
<item name="android:tabWidgetStyle">#style/RR.Tab.Widget</item>
...
</style>
This is the RR.Tab.Widget style: (none of these seem to make such difference)
<style name="RR.Tab.Widget" parent="android:Widget.Holo.Light.TabWidget">
<item name="android:background">#drawable/rrtheme_tab_indicator_holo</item>
<item name="android:tabStripEnabled">false</item>
<item name="android:tabStripLeft">#null</item>
<item name="android:tabStripRight">#null</item>
</style>
This is the generated drawable:
<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/rrtheme_tab_unselected_holo" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/rrtheme_tab_selected_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="#drawable/rrtheme_tab_unselected_focused_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="#drawable/rrtheme_tab_selected_focused_holo" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="#drawable/rrtheme_tab_unselected_pressed_holo" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:drawable="#drawable/rrtheme_tab_selected_pressed_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="#drawable/rrtheme_tab_unselected_pressed_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="#drawable/rrtheme_tab_selected_pressed_holo" />
</selector>
This is what it currently looks like:
All I'm trying to do is change this blue color to green!
Many thanks for your help in advance :)
I recommend you to take a look at this:
Customize Tab indicator (dead link)
Also to have your tab customized use Android Action Bar Style Generator. I always use it to have my Tabs in the color I want.
Hope I helped you
This is my style
<style name="MyCustomTheme" parent="#style/Theme.AppCompat">
<item name="android:actionBarStyle">#style/MyActionBarTheme</item>
<item name="actionBarTabTextStyle">#style/MyActionBarTabText</item>
<item name="android:actionBarTabStyle">#style/customActionBarTabStyle</item>
<item name="actionMenuTextColor">#fff</item>
</style>
<style name="customActionBarTabStyle" parent="#style/Widget.AppCompat.ActionBar.TabView">
<!-- tab indicator -->
<item name="android:background">#ac0910</item>
<!-- Support library compatibility -->
<item name="background">#drawable/actionbar_tab_indicator</item>
</style>
I got this result:
but if i changed my xml to this:
<!-- tab indicator -->
<item name="android:background">#drawable/actionbar_tab_indicator</item>
<!-- Support library compatibility -->
<item name="background">#drawable/actionbar_tab_indicator</item>
</style>
I got this result:
This is my #drawable/actionbar_tab_indicator
<?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="true"
android:drawable="#drawable/tab_selected_pressed" />
</selector>
the most important part is
#drawable/tab_selected_pressed
#drawable/tab_unselected_pressed
#drawable/tab_selected_pressed
...
are images like rectange and fill in colors. this is what i though is the indicator
create a custom layout in the xml as
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/tab_button_drawable"
android:orientation="vertical"
android:padding="10dp" > <TextView
android:id="#+id/tab_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#drawable/text_navigator_color_drawable"
android:textSize="14dp" /></LinearLayout>
and create a method which will return a custom view than define as this after defining the tab view
public View createTabView(final Context context, final String text) {
View view = LayoutInflater.from(context).inflate(R.layout.tab_layout,
null);
TextView tv = (TextView) view.findViewById(R.id.tab_text_view);
tv.setText(text);
return view;
}
tabSpec.setIndicator(createTabView(tabHost.getContext(),
tabWidgetTextView.getText().toString()));
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.
