I want to change the color of the circle of RadioButton in one of my project, 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.
This question is related to
android
android-radiobutton
The answer is
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" />
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 used for unchecked state and colorAccent for checked.
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 >
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.
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>
@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.
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:
See the android reference link for more detail.
To change the radio button color programmatically you can use following:
yourradio button name.buttonDrawable?.setColorFilter(Color.parseColor( color_value), PorterDuff.Mode.SRC_ATOP)
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>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
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!
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>
just use android:buttonTint="@color/colorPrimary" attribute on tag, hope it will help
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.
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"/>
Set the buttonTint property. For example, android:buttonTint="#99FF33".
<android.support.v7.widget.AppCompatRadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:buttonTint="@color/Color" />
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.
There is an xml attribute for it:
android:buttonTint="yourcolor"
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.
<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.
