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.
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
}
Update:
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" />
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>
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.
<android.support.v7.widget.AppCompatRadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:buttonTint="#color/Color" />
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.
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>
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.
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" />
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.
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!
Set the buttonTint property. For example, android:buttonTint="#99FF33".
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.
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>
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.
There is an XML attribute for it:
android:buttonTint="yourcolor"
<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.
Just use the android:buttonTint="#color/colorPrimary" attribute on the <RadioButton> tag.
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.
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);
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 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>
To change the radio button color programmatically you can use following:
yourradio button name.buttonDrawable?.setColorFilter(Color.parseColor( color_value), PorterDuff.Mode.SRC_ATOP)
If you have android:buttonTint it wont work and you have to change it to app:buttonTint.
I had to do this after uprading to androidx.
use app:buttonTint instead of android:buttonTint like this:
<com.google.android.material.radiobutton.MaterialRadioButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="English"
android:checked="true"
app:buttonTint="#FF0000"
android:textAppearance="#style/TextAppearance.Material3.TitleSmall"
android:layout_marginHorizontal="16dp"
android:layoutDirection="rtl"
/>
or
<RadioButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="English"
android:checked="true"
app:buttonTint="#FF0000"
android:textAppearance="#style/TextAppearance.Material3.TitleSmall"
android:layout_marginHorizontal="16dp"
android:layoutDirection="rtl"
/>
create a drawable file my_compound_button_color_selector.xml
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#color/text_app_color"/>
<item android:state_checked="true" android:color="#color/text_app_color"/>
<item android:color="#color/gray"/> </selector>
add style in style.xml file
<style name="AppRadioAppStyle" parent="Widget.AppCompat.CompoundButton.RadioButton">
<item name="android:textColor">#drawable/my_compound_button_color_selector</item>
<item name="drawableTint">#drawable/my_compound_button_color_selector</item>
</style>
layout file
<RadioButton
android:id="#+id/radio1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:button="#null"
android:drawableBottom="?android:attr/listChoiceIndicatorSingle"
android:gravity="center_horizontal|bottom"
android:background="#drawable/app_border_0"
android:padding="#dimen/_15sdp"
android:text="#string/no"
android:fontFamily="#font/poppins_medium"
style="#style/AppRadioAppStyle"
android:layout_marginStart="#dimen/_10sdp"/>
should be add android:button="#null" in your radiobutton
For different colors according to checked and unchecked states please try this -
Create a color resource file #color/radio_button -
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#color/grey" android:state_enabled="false" />
<item android:color="#color/grey" android:state_checked="false" />
<item android:color="#color/green" android:state_enabled="true" />
<item android:color="#color/green" android:state_checked="true" />
</selector>
And then use it like this -
<androidx.appcompat.widget.AppCompatRadioButton
android:id="#+id/radio_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:buttonTint="#color/radio_button" />
This kotlin Extension
fun RadioButton.setLangRadioColor(isCheck: Boolean) {
val color = if (isCheck) {
intArrayOf(
ContextCompat.getColor(rootView.context, R.color.light_red),
ContextCompat.getColor(rootView.context, R.color.light_red)
)
} else {
intArrayOf(
ContextCompat.getColor(rootView.context, R.color.sortRadioUnselectColor),
ContextCompat.getColor(rootView.context, R.color.sortRadioUnselectColor)
)
}
val colorStateList = ColorStateList(
arrayOf(
intArrayOf(-android.R.attr.state_enabled), // disabled
intArrayOf(android.R.attr.state_enabled) // enabled
),
color
)
this.buttonTintList = colorStateList
}
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>
#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.
I got a custom spinner, and I'm trying to replace the 9-patch background / the triangle in the DropDownSelector.
I just can't get it to work right though. I end up with (the white box is a test asset):
the new 9 patch gets shown, but it messes up the padding, and it looks like a Spinner inside a Spinner.
Here's what it looks like without the 9 patch added:
This is what I want it to look like, but then with the new 9patch instead of the old one, not the Spinner in Spinner effect.
Here's my code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Spinner xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/spinner2"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:gravity="center_horizontal"/>
</RelativeLayout>
I add this RelativeLayout to the Actionbar, and set a custom spinner adapter:
SpinnerAdapter mSpinnerAdapter = (new SpinnerCustomAdapterDark(this, R.layout.customSpinnerTitleLayout, categoryNames ));
spinner = findViewById(R.id.spinner2);
categorySpinnerMenuitem = (Spinner) spinner;
categorySpinnerMenuitem.setAdapter(mSpinnerAdapter);
This is the CustomSpinnerTitleLayout set to the adapter:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
style="?android:attr/spinnerDropDownItemStyle"
android:paddingRight="0dp" >
<ImageView
android:id="#+id/spinner_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/icon"
android:layout_gravity="center"
android:paddingRight="0dp"
/>
</LinearLayout>
This is the Theme where I add the 9 patch
<resources>
<style name="CustomTheme" parent="#style/Theme.AppCompat.Light.DarkActionBar">
<item name="android:spinnerDropDownItemStyle">#style/customActionBarDropDownStyle</item>
</style>
<style name="customActionBarDropDownStyle" parent="#android:style/Widget.Holo.Light.ListView" >
<item name="android:background">#drawable/spinner9patch</item>
</style>
</resources>
I'm obviously doing something wrong, but what? I've tried to set the spinnerDropDownItemStyle and the spinnerStyle at the Spinner in the first layout file, what didn't do anything. What am I doing wrong here?
Thanks in advance!!
Create an XML in drawable folder with any name for example spinner_bg.xml and add the following lines
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item><layer-list>
<item><shape>
<gradient android:angle="90" android:endColor="#ffffff" android:startColor="#ffffff" android:type="linear" />
<stroke android:width="1dp" android:color="#504a4b" />
<corners android:radius="5dp" />
<padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp" />
</shape></item>
<item ><bitmap android:gravity="bottom|right" android:src="#drawable/spinner_ab_default_holo_dark_am" /> // you can use any other image here, instead of default_holo_dark_am
</item>
</layer-list></item>
</selector>
Add the following lines to your styles.xml which is inside values folder
<style name="spinner_style" >
<item name="android:background">#drawable/spinner_bg</item>
<item name="android:layout_marginLeft">10dp</item>
<item name="android:layout_marginRight">10dp</item>
<item name="android:layout_marginBottom">10dp</item>
<item name="android:paddingLeft">8dp</item>
<item name="android:paddingTop">5dp</item>
<item name="android:paddingBottom">5dp</item>
Now add this style to your spinner as
<Spinner
android:id="#+id/spinner1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/spinner_style"
android:popupBackground="#cccccc" />
I really recommended you check this out online Generator just make your custom spinner then download file http://jgilfelt.github.io/android-actionbarstylegenerator/
I am beginner in android, and of course i have a problem with ColorStateList.
I want to set it to ListView, but it doesn't work, maybe someone know why?
it is declaration of TextView
<TextView
android:textColor="#color/text_color"
android:id="#+id/tv"
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/in"
android:onClick="onClick"
android:clickable="true"
android:duplicateParentState='true'/>
and content of text_color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:color="#ffff0000"/> <!-- pressed -->
<item android:state_focused="true"
android:color="#ff0000ff"/> <!-- focused -->
<item android:color="#ff000000"/> <!-- default -->
</selector>
It is code from StackOverflow reply, should work :/
Try by setting listview.setItemsCanFocus(true);
I'm trying to implement DashboardLayout (Pattern 3).
All ok when orientation is portrait:
But when orientation of app changes to album it looks like:
Here is the source code of DashboardLayout.java
Activity layout file as in example:
<?xml version="1.0" encoding="utf-8"?>
<com.example.ui.DashboardLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/dashboard_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white" >
<Button
android:id="#+id/posts"
style="#style/DashboardButton"
android:drawableTop="#drawable/ic_db_posts"
android:onClick="onClick"
android:text="posts" />
***and four same buttons***
</com.example.ui.DashboardLayout>
style/DashboardButton:
<style name="DashboardButton">
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:gravity">center_horizontal</item>
<item name="android:layout_gravity">center_vertical</item>
<item name="android:background">#drawable/db_buttons</item>
<item name="android:textStyle">bold</item>
<item name="android:textSize">16sp</item>
<item name="android:textColor">#000000</item>
</style>
Background only for button pressed state:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:state_pressed="true"
android:drawable="#drawable/db_button_bd_pressed" />
</selector>
Pressed:
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<padding
android:left="10dp"
android:top="20dp"
android:right="10dp"
android:bottom="20dp" />
<corners android:radius="10dp" />
<solid android:color="#a6cee1" />
</shape>
Where is the problem? Help me, please.
The Dashboardlayout just works if the number of buttons is even. You have an odd number, just insert an extra button with:
android:background="#null" or "#ffffffff"//transparent
So it will handle it like a extra button but it is transparent.
