Change Tabview Color Based on Which Tab Is Selected -Swiftui

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.

How to change to color of react-native-tab-view?

Changing the background color of the tab-bar

If you refer to this section, the styling props for the tab-bar will have to be passed after declaring a custom React component using the renderTabBar prop.

<TabView
  navigationState={{ index, routes }}
  renderScene={renderScene}
  onIndexChange={setIndex}
  initialLayout={initialLayout}
  renderTabBar={props => <TabBar {...props} style={{backgroundColor: 'black'}}/>} // <-- add this line
/>

Changing the text color of the tab-bar

If you refer to this,

<TabBar
  renderLabel={({route, color}) => (
    <Text style={{ color: 'black', margin: 8 }}>
      {route.title}
    </Text>
  )}
  style={{backgroundColor: 'white'}}
  ...
/>

Feel free to experiment further using the example snack. :)

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>

Change the color of selected Tab, of TabMenu PRIMENG - style

Sorry for the delayed answer. Just to keep in mind you should add :host ::ng-deep before your css class to override any style

:host ::ng-deep .ui-tabmenu .ui-tabmenu-nav .ui-tabmenuitem.ui-state-active {
    background-color: #d90096; //<Replace your custom color>
    border: 1px solid #d600d9;
}

Hopefully it will save your time.

How to change selected tab title color in Xamarin

I need Black for selected tab and gray for unselected tab.

You don't need to use CustomRender to achieve this.
You can just use properties UnselectedTabColor and SelectedTabColor of TabbedPage .

Please refer to the following code:

<?xml version="1.0" encoding="UTF-8"?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" 
            xmlns:local="clr-namespace:TabbedPageWithNavigationPage;assembly=TabbedPageWithNavigationPage" 
            x:Class="TabbedPageWithNavigationPage.MainPage"
            UnselectedTabColor="Gray"
            SelectedTabColor="Black"
            >
    
</TabbedPage>

TabBar icon color when tab is selected

To change the selected tab color, you just need to add this to TabBar :

labelColor: Colors.
unselectedLabelColor: Colors.white,

Full code:

DefaultTabController(
      length: 2,
      child: Scaffold(
        appBar: AppBar(
          bottom: TabBar(
            labelColor: Colors.deepOrange,
            unselectedLabelColor: Colors.white,
            tabs: <Tab>[
              Tab(
                child: Row(
                  children: <Widget>[
                    Text("Select", textAlign: TextAlign.start),
                    SizedBox(
                      width: 24.0,
                    ),
                    Icon(
                      Icons.arrow_drop_down,
                      color: Colors.blue.shade400,
                    ),
                  ],
                ),
              ),
              Tab(
                child: Row(
                  children: <Widget>[
                    Text("Select", textAlign: TextAlign.start),
                    SizedBox(
                      width: 24.0,
                    ),
                    Icon(
                      Icons.arrow_drop_down,
                      color: Colors.blue.shade400,
                    ),
                  ],
                ),
              ),
            ],
          ),
        ),
        body: Center(
          child: Container(
            child: Text("This is a page blahblah"),
          ),
        ),
      ),
    )

EDIT:
If u want to only change the icon color, then add color to Text and remove the color from the Icon in Tab, Code:

DefaultTabController(
      length: 2,
      child: Scaffold(
        appBar: AppBar(
          bottom: TabBar(
            labelColor: Colors.deepOrange,
            unselectedLabelColor: Colors.white,
            tabs: <Tab>[
              Tab(
                child: Row(
                  children: <Widget>[
                    Text("Select", textAlign: TextAlign.start, style: TextStyle(color: Colors.white),),
                    SizedBox(
                      width: 24.0,
                    ),
                    Icon(
                      Icons.arrow_drop_down,
                    ),
                  ],
                ),
              ),
              Tab(
                child: Row(
                  children: <Widget>[
                    Text("Select", textAlign: TextAlign.start, style: TextStyle(color: Colors.white),),
                    SizedBox(
                      width: 24.0,
                    ),
                    Icon(
                      Icons.arrow_drop_down,

                    ),
                  ],
                ),
              ),
            ],
          ),
        ),
        body: Center(
          child: Container(
            child: Text("This is a page blahblah"),
          ),
        ),
      ),
    )

EDIT #2
Now , This code changes the Icon color, but leaves the text color change as default (You can customize the change for color of text like the icon color). Code:

import 'package:flutter/material.dart';

class FirstPage extends StatefulWidget {
  @override
  _FirstPageState createState() => _FirstPageState();
}

class _FirstPageState extends State<FirstPage> {
  int _currentIndex = 0;
  @override
  Widget build(BuildContext context) {
    return DefaultTabController(
      length: 2,
      child: Scaffold(
        appBar: AppBar(
          bottom: TabBar(
            onTap: (index){
              setState(() {
               _currentIndex = index; 
              });
            },

            tabs: <Tab>[
              Tab(
                child: Row(
                  children: <Widget>[
                    Text("Select", textAlign: TextAlign.start,),
                    SizedBox(
                      width: 24.0,
                    ),
                    Icon(
                      Icons.arrow_drop_down,
                      color: _currentIndex == 0 ? Colors.deepOrange : Colors.white54
                    ),
                  ],
                ),
              ),
              Tab(
                child: Row(
                  children: <Widget>[
                    Text("Select", textAlign: TextAlign.start,),
                    SizedBox(
                      width: 24.0,
                    ),
                    Icon(
                      Icons.arrow_drop_down,
                      color: _currentIndex == 1 ? Colors.deepOrange : Colors.white54,
                    ),
                  ],
                ),
              ),
            ],
          ),
        ),
        body: Center(
          child: Container(
            child: Text("This is a page blahblah"),
          ),
        ),
      ),
    );
  }
}
