Change the circle color of radio button

Question

I want to change the color of the circle of RadioButton in one of my projects, but I could not understand which property to set. The background color is black, so it gets invisible. I want to set the color of the circle to white.

Answer 1

It is simpler just setting 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 file, put your color, in this case a reddish one:

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

Result:

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 2

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"

A 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, you should call it 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:

See the Android reference link for more detail.

Answer 3

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

Answer 4

This is 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 file:

<?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 file:

<?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 5

1. Declare a 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 the 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"/>
   

But only if your activity extends AppCompatActivity.

Answer 6

For under API 21

Create a custom style RadioButton:

File 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 the layout, use the theme:

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

---

For API 21 and higher

Just use buttonTint:

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

Answer 7

You have to use this code:

<android.support.v7.widget.AppCompatRadioButton
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    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 8

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 9

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

Answer 10

I made it the 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 file 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>

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

Answer 11

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:

colorControlNormal is used for the unchecked state and colorAccent for checked.

Answer 12

For those who want to change disable, checked and enabled states you can 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 the 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 13

There is an XML attribute for it:

android:buttonTint="yourcolor"

Answer 14

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

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

Answer 15

Just use the android:buttonTint="@color/colorPrimary" attribute on the <RadioButton> tag.

Answer 16

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 17

You can do it this way in XML with the android:buttonTint attribute:

<RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/radio"
    android:checked="false"
    android:padding="5dp"
    android:buttonTint="@color/radio_color"/>

You can do it this way in Java using android:buttonTint:

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

    new int[]{
        DataUtils.getColorResource(mContext, R.color.colorBlack), // Unchecked
        DataUtils.getColorResource(mContext, R.color.colorPrimary) // Checked
    }
);

RadioButton radio = findViewById(R.id.radio);   
radio.setButtonTintList(colorStateList);

Answer 18

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 19

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 attribute 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>

</resources>

Answer 20

To change the radio button color programmatically you can use following:

yourradio button name.buttonDrawable?.setColorFilter(Color.parseColor( color_value), PorterDuff.Mode.SRC_ATOP)

Answer 21

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

android:buttonTint="@drawable/radiobutton" in the XML content of the radiobutton and your radiobutton.xml file 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"/>
</selector>

Answer 22

@jh314 is correct.

In file AndroidManifest.xml,

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

In file 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.
