How to Change Color of the Toggle Button

How to change indicator color in Toggle Button ( Android)

I think you are going to have to create 2 custom images of the button and then use a drawable xml as the background.

For Example:

<ToggleButton
    android:id="@+id/toggleButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/btntoggle_selector"
    android:textColor="@android:color/white"
    android:textOff="Toggle Button OFF"
    android:textOn="Toggle Button ON "
    android:onClick="onToggleButtonClick" />

Then the btntoggle_selector xml

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

bg_selected and bg_normal are just images like 9-patch.

See the Android developer guide on 9-patch images

Toggle button background color when clicked

Far better off to attach a class to the button on the click and have the styling on that class.

The following snippet has the base background color set for the button and then when its clicked - toggles a"clicked" class - that when applied - provides an alternate background color.

This is simpler to implement because you are not having to determine the existing background color followed by some funky hex comparison and also its much better to separate the html, js and css into their own realms.

let testButton = document.getElementById("testbutton");

testButton.addEventListener("click", () => {
  testButton.classList.toggle('clicked');
})

#testbutton {
  background-color: #0f2e0c;
  color: white
}

#testbutton.clicked {
  background-color: #ba0202;
}

<button id="testbutton">Toggle</button>

change color of my ToggleButton when clicked

You have to create new file in drawable directory with list of states.

You can name it toggle_background.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- WHEN IS CHECKED -->
    <item android:drawable="@color/colorPrimary" android:state_checked="false" />

    <!-- WHEN IS NOT CHECKED -->
    <item android:drawable="@color/colorAccent" android:state_checked="true" />

</selector>

Above file you can use as background of ToggleButton:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ToggleButton
        android:id="@+id/toggleButton_monday"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/toggle_background"
        android:textOff="ON"
        android:textOn="OFF" />

</LinearLayout>

By default button has grey border. When would you like to remove it just add:

style="?android:attr/borderlessButtonStyle"

to your ToggleButton in xml file.

You can also add OnCheckedChangeListener. If you have many buttons you can add all of them to the list, and in loop add that same listener for all of them:

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.widget.CompoundButton;
import android.widget.ToggleButton;

import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {

    private List<ToggleButton> listOfButtons = new ArrayList<>();

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Add ToggleButtons to list
        listOfButtons.add(findViewById(R.id.toggleButton_monday));

        // Create listener for all of them
        CompoundButton.OnCheckedChangeListener listener = (buttonView, isChecked) -> {
            // Do something
        };

        // Add listener to all od buttons
        for (ToggleButton button : listOfButtons) {
            button.setOnCheckedChangeListener(listener);
        }
    }
}

How to set color of toggle buttons

matButtonToggle does not support the color property like matButton.

You can use the css classes .mat-button-toggle and .mat-button-toggle-checked to style the different states.

With material theming you can extract whichever individual palettes you need from the theme and apply the backgrounds default-contrast color to the text color to achieve optimal contrast with light or dark colors.

Here is a Stackblitz with your mat-button-toggle-group example: Stackblitz
angular-t1k1x6

Theming used:

@import '~@angular/material/theming';

@include mat-core();

$app-primary: mat-palette($mat-indigo);
$app-accent:  mat-palette($mat-pink, A200, A100, A400);

$app-theme: mat-light-theme($app-primary, $app-accent);

@mixin mix-app-theme($app-theme) {
  $primary: map-get($app-theme, primary);
  $accent: map-get($app-theme, accent);

  .mat-button-toggle {
    background-color: mat-color($primary);
    color: mat-color($primary, default-contrast);
  }

  .mat-button-toggle-checked {
    background-color: mat-color($accent);
    color: mat-color($accent, default-contrast);
  }
}

// Include the mixin
@include mix-app-theme($app-theme);

Change toggleButton color

try this way.

ToggleButton :

<ToggleButton 
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:textOn="On"
    android:textOff="Off"
    android:textSize="20sp"
    android:background="@drawable/toggle_day_bg_selector" />

toggle_day_bg_selector.xml

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

toggle_on.xml

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

</shape>

toggle_off.xml

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

</shape>

Hope this will help.

EDIT :

use this drawable files for showing images on ToggleButton

toggle_off.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item>
        <shape
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="oval" >
            <solid android:color="@android:color/holo_green_dark" />
        </shape>

            <solid android:color="@android:color/holo_green_dark" />
        </shape>
    </item>

Background color of toggle buttons

True, not selected toggle buttons are transparent... couldn't find anything about setting the background color for them in the official documentation.

So, how about setting the background of the parent container?

Is this solution satisfactory for your needs?

Sample Image

              Container(
                padding: EdgeInsets.zero,
                decoration: BoxDecoration(
                  color: Colors.yellow,
                  border: Border.all(color: Colors.black, width: 1.0),
                  borderRadius: BorderRadius.all(Radius.circular(5.0)),
                ),
                child: ToggleButtons(
                  selectedColor: Colors.white,
                  borderRadius: BorderRadius.circular(5),
                  fillColor: Colors.blue,
                  children: [Text('Option1'), Text('Option2'), Text('Option3')],
                  isSelected: [true, false, false],
                  onPressed: (d) {},
                ),
              ),
