android – Change Circle color of radio button

Posted by: admin March 10, 2020 Leave a comment

Questions:

I want to change the color of circle of RadioButton, I could not understand which property to set. The background color I am having is black so it gets invisible. I want to set the color of the circle to white.

How to&Answers:

More simple, just set the buttonTint color: (only works on api level 21 or above)

<RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/radio"
    android:checked="true"
    android:buttonTint="@color/your_color"/>

in your values/colors.xml put your color in this case a reddish one:

<color name="your_color">#e75748</color>

Result:

Colored Android Radio Button

If you want to do it by code (also api 21 and above):

if(Build.VERSION.SDK_INT>=21)
{

    ColorStateList colorStateList = new ColorStateList(
            new int[][]{

                    new int[]{-android.R.attr.state_enabled}, //disabled
                    new int[]{android.R.attr.state_enabled} //enabled
            },
            new int[] {

                    Color.BLACK //disabled
                    ,Color.BLUE //enabled

            }
        );                       


    radio.setButtonTintList(colorStateList);//set the color tint list
    radio.invalidate(); //could not be necessary
}

Answer:

Update:
1. use this one instead

   <android.support.v7.widget.AppCompatRadioButton
        android:id="@+id/rbtn_test"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:buttonTint="@color/primary" />

2. Then add this line into parent layout or Alt + Enter in Android Studio to auto-add
xmlns:app="http://schemas.android.com/apk/res-auto"

Minimum Example should look like this:

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

    <android.support.v7.widget.AppCompatRadioButton
        android:id="@+id/rbtn_test"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:buttonTint="@color/primary" />

</LinearLayout>

3. In your program, should call like this.

AppCompatRadioButton radioButton = (AppCompatRadioButton) view.findViewById(R.id.rbtn_test);

Basically, this kind of pattern can be applied for all AppCompact types such as AppCompatCheckBox, AppCompatButton and so on.

Old Answer:

In order to support below android API 21, you can use AppCompatRadioButton. Then use setSupportButtonTintList method to change the color. This is my code snippet to create a radio button .

    AppCompatRadioButton rb;
    rb = new AppCompatRadioButton(mContext);

    ColorStateList colorStateList = new ColorStateList(
            new int[][]{
                    new int[]{-android.R.attr.state_checked},
                    new int[]{android.R.attr.state_checked}
            },
            new int[]{

                    Color.DKGRAY
                    , Color.rgb (242,81,112),
            }
    );
    rb.setSupportButtonTintList(colorStateList);

Tested result at API 19:

This one is tested on API 19

See the android reference link for more detail.

Answer:

<android.support.v7.widget.AppCompatRadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:buttonTint="@color/Color" />

Answer:

Working on API pre 21 as well as post 21.
In your styles.xml put:

<!-- custom style -->
<style name="radionbutton"
       parent="Base.Widget.AppCompat.CompoundButton.RadioButton">
    <item name="android:button">@drawable/radiobutton_drawable</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">false</item>
    <item name="android:backgroundDimEnabled">true</item>
</style>

Your radio button in xml should look like:

<RadioButton
    android:layout_width="wrap_content"
    style="@style/radionbutton"
    android:checked="false"
    android:layout_height="wrap_content"
    />

Now all you need to do is make a radiobutton_drawable.xml in your drawable folder. Here is what you need to put in it:

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

Your radio_unchecked.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
  android:shape="oval">
  <stroke android:width="1dp" android:color="@color/colorAccent"/>
  <size android:width="30dp" android:height="30dp"/>
</shape>

Your radio_checked.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item>
    <shape android:shape="oval">
      <stroke android:width="1dp" android:color="@color/colorAccent"/>
      <size android:width="30dp" android:height="30dp"/>
    </shape>
  </item>
  <item android:top="5dp" android:bottom="5dp" android:left="5dp" android:right="5dp">
    <shape android:shape="oval">
      <solid android:width="1dp" android:color="@color/colorAccent"/>
      <size android:width="10dp" android:height="10dp"/>
    </shape>
  </item>
</layer-list>

Just replace @color/colorAccent with the color of your choice.

Answer:

You have to use this code:

<android.support.v7.widget.AppCompatRadioButton
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:buttonTint="@color/black"
                    android:text="Radiobutton1"
                    app:buttonTint="@color/black" />

Using app:buttonTint instead of android:buttonTint and also android.support.v7.widget.AppCompatRadioButton instead of Radiobutton!

Answer:

  1. Declare custom style in your styles.xml file.

    <style name="MyRadioButton" parent="Theme.AppCompat.Light">  
      <item name="colorControlNormal">@color/indigo</item>
      <item name="colorControlActivated">@color/pink</item>
    </style>  
    
  2. Apply this style to your RadioButton via android:theme attribute.

    <RadioButton  
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:checked="true"
        android:text="Radio Button"
        android:theme="@style/MyRadioButton"/>
    

    only if your activity extends AppCompatActivity

Answer:

For under API 21

Create custom style RadioButton
style.xml

 <style name="RadioButton" parent="Theme.AppCompat.Light">
     <item name="colorAccent">@color/green</item>
     <item name="android:textColorSecondary">@color/mediumGray</item>
     <item name="colorControlNormal">@color/red</item>
 </style>

In layout use theme:

<RadioButton
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:theme="@style/RadioButton" />

For API 21 and more

Just use buttonTint

 <RadioButton
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:buttonTint="@color/green" />

Answer:

The question is old but i think my answer will help people.
You can change the color of radio button’s unchecked and checked state by using style in xml.

<RadioButton
    android:id="@+id/rb"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/RadioButtonStyle" />

In style.xml

<style name="RadioButtonStyle" parent="Theme.AppCompat.Light">
        <item name="colorAccent">@android:color/white</item>
        <item name="android:textColorSecondary">@android:color/white</item>
</style>

You can set the desired colors in this style.

Answer:

Set the buttonTint property. For example, android:buttonTint="#99FF33".

Answer:

I made it short way like this (Working on API pre 21 as well as post 21)

Your radio button in xml should look like this

  <RadioButton android:id="@+id/radioid"                    
                android:layout_height="wrap_content"
                android:layout_width="wrap_content"                 
                android:button="@drawable/radiodraw" />

in radiodraw.xml

  <?xml version="1.0" encoding="utf-8"?>
  <selector xmlns:android="http://schemas.android.com/apk/res/android">    
      <item android:state_checked="false" >
          <shape  android:shape="oval" >
              <stroke android:width="1dp" android:color="#000"/>
              <size android:width="30dp" android:height="30dp"/>
              <solid android:color="@android:color/transparent"/>
          </shape>
      </item>
      <item android:state_checked="true">
          <layer-list>
              <item>
                  <shape android:shape="oval">
                      <stroke android:width="1dp" android:color="#000"/>
                      <size android:width="30dp" android:height="30dp"/>
                      <solid android:color="@android:color/transparent"/>
                  </shape>
              </item>
              <item android:top="5dp" android:bottom="5dp" android:left="5dp" android:right="5dp">
                  <shape android:shape="oval">
                      <solid android:width="1dp" android:color="#000"/>
                      <size android:width="10dp" android:height="10dp"/>
                  </shape>
              </item>
          </layer-list>
      </item>
  </selector>

have to add color transparent for drawing the unchecked status ;else it draw solid black oval.

Answer:

Sometimes you just need to override colorControlNormal like this:

    <style name="RadioButtonStyle" parent="AppTheme">
       <item name="colorControlNormal">@color/pink</item>
       <item name="colorAccent">@color/colorPrimary</item>
       <item name="android:textColorSecondary">@color/black</item>
    </style>

And you will get a button like this:

enter image description here

colorControlNormal used for unchecked state and colorAccent for checked.

Answer:

There is an xml attribute for it:

android:buttonTint="yourcolor"

Answer:

<RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/radio"
    android:buttonTint="@color/my_color"/>

All button will change color, the circle box and the central check.

Answer:

For those who want to change disable, checked and enabled states you cat do the following steps:

<!-- Or androidX radio button or material design radio button -->
<android.support.v7.widget.AppCompatRadioButton
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:buttonTint="@color/black"
                    android:text="Radiobutton1"
                    app:buttonTint="@color/radio_button_color" />

then in color res folder make a file named “radio_button_color.xml”:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/yellow900" android:state_selected="true" />
    <item android:color="@color/yellow800" android:state_checked="true" />
    <item android:color="@color/gray800" android:state_enabled="false" />
    <item android:color="@color/yellow800" android:state_enabled="true" />
</selector>

Answer:

RadioButton by default takes the colour of colorAccent in res/values/colors.xml file.
So go to that file and change the value of

<color name="colorAccent">#3F51B5</color>

to the colour you want.

Answer:

The easiest way is to change colourAccent color in values->colours.xml
but be aware that it will also change other things like edit text cursor color etc..

< color name="colorAccent">#75aeff</color >

Answer:

If you want to set different color for clicked and unclicked radio button just use:

   android:buttonTint="@drawable/radiobutton"  in xml of the radiobutton and your radiobutton.xml will be:  
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#1E88E5"/>
<item android:state_checked="true" android:color="#00e676"/>
<item android:color="#ffffff"/>

Answer:

just use android:buttonTint="@color/colorPrimary" attribute on tag, hope it will help

Answer:

I had this problem. If your app has a black background and you have a lot of RadioButtons that are invisible due to the background, it is complicated to edit the android: buttonTint of each one, the best solution is to change the parent theme in your styles.xml file

I changed

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

to

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">

So the RadioButtons’ circles became a lighter shade of gray and now they are visible even with a black background.

This is my style.xml file:

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

Answer:

@jh314 is correct.
In AndroidManifest.xml,

 <application
    android:allowBackup="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"></application>

In style.xml

  <!-- Application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorAccent">@color/red</item>
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

the item name must be colorAccent,it decides the application’s widgets default color.

But if you want to change the color in code,Maybe @aknay’s answer is correct.
