How to Change a Tab Background Color When Using Tablayout

How do I change a tab background color when using TabLayout?

What finally worked for me is similar to what @如果我是DJ suggested, but the tabBackground should be in the layout file and not inside the style, so it looks like:

res/layout/somefile.xml:

<android.support.design.widget.TabLayout
    ....
    app:tabBackground="@drawable/tab_color_selector"
    ...
    />

and the selector
res/drawable/tab_color_selector.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/tab_background_selected" android:state_selected="true"/>
    <item android:drawable="@color/tab_background_unselected"/>
</selector>

Changing the color of selected tab

you can do it like this in your tab layout widget

<android.support.design.widget.TabLayout

    app:tabBackground="@drawable/selector"

    />

and define your selector.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
     android:drawable="@color/tab_selected_color" 
     android:state_selected="true"/>
    <item 
     android:drawable="@color/tab_unselected_color"
     android:state_selected="false"/>
</selector>

How to change color of tab selected in tablayout

For anyone who is looking for a solution to this. I was able to find one. You can apply the color to the layout of the child of the tabLayout. For some reference code this is what I used a worked really well for me

final LinearLayout tabsContainerLayout = (LinearLayout)expenseTabs.getChildAt(0);
Linear LayouttempLinearLayout = (LinearLayout)tabsContainerLayout.getChildAt(selectedTabPosition);
tempLinearLayout.setBackgroundColor(Color.RED);

How to set Tab background color the new TabLayout material components

Here are the steps to set the Tab background color:

first the code and then some brief explanation:

The code:

The Explanation

tabBackground: is the tab background and should be a drawable selector.

tabIconTint: is for icon color and it must me color selector.

tabIndicator="@null" : as it is useless in this case.

tabSelectedTextColor, tabTextColor are self explanatory.

How to change background color of Tablayout from a fragment?

You can change background color of tablayout using addOnTabSelectedListener of tablyout according to position of tabs, like below code:

     tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
                @Override
                public void onTabSelected(TabLayout.Tab tab) {
                    viewPager.setCurrentItem(tab.getPosition());
                    switch (tab.getPosition()){
// Change color of tab layout according to tab position
 
                        case 0:
                            tabLayout.setBackgroundColor(getResources().getColor(R.color.black));
                            break;
                        case 1:
                            tabLayout.setBackgroundColor(getResources().getColor(R.color.teal_200));
                            break;
                        default:
                            tabLayout.setBackgroundColor(getResources().getColor(R.color.black));
                            break;
    
                    }
                }
    
                @Override
                public void onTabUnselected(TabLayout.Tab tab) {
    
                }
    
                @Override
                public void onTabReselected(TabLayout.Tab tab) {
    
                }
            });

Changing the background color of a Tab in TabLayout (Android design support library) doesn't occupy the entire tab space

Define a selector as a drawable, and also have a drawable for the selected/unselected states.

For this solution, I started with the code from this answer, and then added the functionality that changes the background color for the current Tab.

First, the selector, tab_background.xml in the drawable folder:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/tab_background_selected" android:state_selected="true" />
    <item android:drawable="@drawable/tab_background_unselected" android:state_selected="false" android:state_focused="false" android:state_pressed="false" />
</selector>

Then, tab_background_selected.xml in the drawable folder:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="#d13fdd1a" />
</shape>

Then, tab_background_unselected.xml in the drawable folder:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="#3F51B5" />
</shape>

Finally, in your styles.xml, specify the selector to use, and also specify the tab indicator style, since the app:tabIndicatorColor property in the TabLayout will now be ignored:

<style name="Base.Widget.Design.TabLayout" parent="android:Widget">
    <item name="tabBackground">@drawable/tab_background</item>
    <item name="tabIndicatorColor">#ff00ff</item>
    <item name="tabIndicatorHeight">2dp</item>
</style>

Result with the example colors above:

Additional Note:

Tested with the 23.3.0 versions of the support library components:

dependencies {
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.android.support:cardview-v7:23.3.0'
    compile 'com.android.support:recyclerview-v7:23.3.0'
    compile 'com.android.support:design:23.3.0'
    compile 'com.android.support:support-v4:23.3.0'
}

Android - How to change the background color or the entire TabLayout dynamically?

I solved it by checking the boolean that I have set for night theme prior to setting the content view in onCreate.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    SharedPreferences nightModeSwitchState = getSharedPreferences("NightModeSwitchState", 0);
    mNightModeSwitchState = nightModeSwitchState.getBoolean("NightModeSwitchState", false);

    if (mNightModeSwitchState) {
        setContentView(R.layout.activity_book_night);
    } else {
        setContentView(R.layout.activity_book);
    }

I have two layouts made both include tabLayouts. One of them references a style file for tabLayout set to night mode colors with the dark background and the layout references a style file set to regular colors for the tablayout.

<style name="CategoryTab" parent="Widget.Design.TabLayout">
    <item name="tabIndicatorColor">@android:color/white</item>
    <item name="tabSelectedTextColor">@android:color/white</item>
    <item name="tabTextAppearance">@style/CategoryTabTextAppearance</item>
    <item name="tabBackground">@drawable/tab_regular_theme</item>
    <item name="android:textColorSecondary">@android:color/white</item>
</style>

<style name="CategoryTabNight" parent="Widget.Design.TabLayout">
    <item name="tabIndicatorColor">@android:color/white</item>
    <item name="tabSelectedTextColor">@android:color/white</item>
    <item name="tabTextAppearance">@style/CategoryTabTextAppearance</item>
    <item name="tabBackground">@drawable/tab_layout_dark_mode</item>
    <item name="android:textColorSecondary">@android:color/white</item>
</style>

The style files reference different drawables that control the background colors as you can see above.. and here are the drawables...

Here is night mode drawable:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/dark_grey" android:state_selected="true"/>
<item android:drawable="@color/dark_grey"/>
</selector>

Here is regular mode drawable:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/app_bar" android:state_selected="true"/>
<item android:drawable="@color/app_bar"/>
</selector>

Everything else is the layouts are identical as not to mess anything up just the style files for the tablayouts are changed. I hope this makes sense. I tested it and it works for me. I have tried so many other things and nothing worked. It is important to call Shared Preference to get the value before checking the boolean. I hope this helps someone.

How to change selected Tab Text color using TabLayout from code in Android?

If you are using the design support library add this code to your tab activity.

tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#FF0000"));
tabLayout.setSelectedTabIndicatorHeight((int) (5 * getResources().getDisplayMetrics().density));
tabLayout.setTabTextColors(Color.parseColor("#727272"), Color.parseColor("#ffffff"));

This will set the tab text color as well as tab indicator color in your tab activity.
