Change "On" Color of a Switch

Change on color of a Switch

As of now it is better to use SwitchCompat from the AppCompat.v7 library. You can then use simple styling to change the color of your components.

values/themes.xml:

<style name="Theme.MyTheme" parent="Theme.AppCompat.Light">
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/my_awesome_color</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/my_awesome_darker_color</item>

    <!-- colorAccent is used as the default value for colorControlActivated,
         which is used to tint widgets -->
    <item name="colorAccent">@color/accent</item>

    <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight, and colorSwitchThumbNormal. -->

</style>

EDIT:

The way in which it should be correctly applied is through android:theme="@style/Theme.MyTheme"
and also this can be applied to parent styles such as EditTexts, RadioButtons, Switches, CheckBoxes and ProgressBars:

<style name="My.Widget.ProgressBar" parent="Widget.AppCompat.ProgressBar">

<style name="My.Widget.Checkbox" parent="Widget.AppCompat.CompoundButton.CheckBox">

Change color of Switch in Android

As per this, (direct answer by BoD copy-paste):

You must not use android:thumb and android:track, but instead, app:thumb and app:track And you must add the following to the root of your xml document:
xmlns:app="http://schemas.android.com/apk/res-auto"

Change the Color of a Switch - FormBuilderSwitch - flutter

You can use bool to do that

Example:

bool switched = false; //Based on which state you want it to be on init

Widget to trigger switch function

FormBuilderSwitch(
                        onChanged: (bool) {
                          setState(() {
                            bool = !bool;
                            switched = bool;
                          });
                        },
                      )

and here's an example of color change based on bool

Container(
   color: switched? Colors.white : Colors.blue,
)

Update :

Here's the code

FormBuilderSwitch(
              name: "public",
              title: Text("Wird noch ein Mitspieler gesucht?"),
              initialValue: false,
              controlAffinity: ListTileControlAffinity.leading,
              decoration: InputDecoration(border: InputBorder.none),
              onChanged: (bool) {
                setState(() {
                  bool = !bool;
                  switched = bool;
                });
              },
            ),
            Container(
              height: 20, 
              width: 20, 
              color: switched ? Colors.black54 : Colors.blue,
            ),

Change color of Switch while turning OFF react-native

onTintColor has been deprecated try the following.

  <Switch 
      trackColor={{true: 'red', false: 'grey'}}
      onValueChange={this.toggleSwitch}
      value={true}/>

this works

Changing the background color of a Switch

The background is called a track and you can change the color of it by using

app:trackTint="@color/darkThemeGreyTextColor"

The "button" is called a thumb
and you can change the color of it with

app:thumbTint="@color/heartRed"

I didn't see these attributes because I was using the android: prefix instead of the app: prefix to see the available options.

How to Change Color of Knob in Bootstrap 5 Switch

It will work if you change the fill color correctly.

That means you can use a hex color with the appropriate escape %23 for the # character.

For example: #cc2222

fill='%23cc2222'/%3e%3c/svg%3e"

Or, you can used a named color...

For example: red

fill='red'/%3e%3c/svg%3e"

Or, you can use an RGB color with the appropriate escapes for parens (%28,%29)...

For example: rgba(100, 0, 0, .25)

fill='rgba%28100, 0, 0, 0.25%29'/%3e%3c/svg%3e"

Demo

How can I change the checked background color of this Bootstrap 4 toggle switch?

You can simply altered every possible properties that can affect the color like

.custom-control-input:checked, .custom-control-label::before, .custom-control-input:active and .custom-control-input:focus

but you have to pay attention on altering .custom-control-input::after because it will destroy the pointer inside the toggle switch

Example

.custom-control-input:focus~.custom-control-label::before {
  border-color: red !important;
  box-shadow: 0 0 0 0.2rem rgba(255, 47, 69, 0.25) !important;
}

.custom-control-input:checked~.custom-control-label::before {
  border-color: red !important;
  background-color: red !important;
}

.custom-control-input:active~.custom-control-label::before {
  background-color: red !important;
  border-color: red !important;
}

.custom-control-input:focus:not(:checked)~.custom-control-label::before {
  border-color: red !important;
}

.custom-control-input-green:not(:disabled):active~.custom-control-label::before {
  background-color: red !important;
  border-color: red !important;
}

<link rel="stylesheet" type="text/css" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
<div class="custom-control custom-switch">
  <input type="checkbox" class="custom-control-input" id="darkSwitch" />
  <label class="custom-control-label" for="darkSwitch">Dark Mode</label>
</div>

How to change the color of a SwitchCompat from AppCompat library

AppCompat tinting attributs:

First, you should take a look to appCompat lib article there and to different attributs you can set:

colorPrimary: The primary branding color for the app. By default, this is the color applied to the action bar background.

colorPrimaryDark: Dark variant of the primary branding color. By default, this is the color applied to the status bar (via statusBarColor) and navigation bar (via navigationBarColor).

colorAccent: Bright complement to the primary branding color. By default, this is the color applied to framework controls (via colorControlActivated).

colorControlNormal: The color applied to framework controls in their normal state.

colorControlActivated: The color applied to framework controls in their activated (ex. checked, switch on) state.

colorControlHighlight: The color applied to framework control highlights (ex. ripples, list selectors).

colorButtonNormal: The color applied to framework buttons in their normal state.

colorSwitchThumbNormal: The color applied to framework switch thumbs in their normal state. (switch off)

If all custom switches are the same in a single activity:

With previous attributes you can define your own theme for each activity:

<style name="Theme.MyActivityTheme" parent="Theme.AppCompat.Light">
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/my_awesome_color</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/my_awesome_darker_color</item>

    <!-- colorAccent is used as the default value for colorControlActivated,
         which is used to tint widgets -->
    <item name="colorAccent">@color/accent</item>

    <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight, and colorSwitchThumbNormal. -->

</style>

and :

<manifest>
...
    <activity
        android:name=".MainActivity" 
        android:theme="@style/Theme.MyActivityTheme">
    </activity>
...
</manifest>

If you want to have differents custom switches in a single activity:

As widget tinting in appcompat works by intercepting any layout inflation and inserting a special tint-aware version of the widget in its place (See Chris Banes post about it) you can not apply a custom style to each switch of your layout xml file. You have to set a custom Context that will tint switch with right colors.

~~To do so for pre-5.0 you need to create a Context that overlays global theme with customs attributs and then create your switches programmatically:~~

ContextThemeWrapper ctw = ContextThemeWrapper(getActivity(), R.style.Color1SwitchStyle); 
SwitchCompat sc = new SwitchCompat(ctw)

As of AppCompat v22.1 you can use the following XML to apply a theme to the switch widget:

<RelativeLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    ...>

    <android.support.v7.widget.SwitchCompat
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:theme="@style/Color1SwitchStyle"/>

Your custom switch theme:

<style name="Color1SwitchStyle">
    <item name="colorControlActivated">@color/my_awesome_color</item>
</style>

On Android 5.0 it looks like a new view attribut comes to life : android:theme (same as one use for activity declaration in manifest). Based on another Chris Banes post, with the latter you should be able to define a custom theme directly on a view from your layout xml:

<android.support.v7.widget.SwitchCompat
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/Color1SwitchStyle"/>
