RadioButton is leaving black checked circle after unchecking

Question

My RadioButtons in my RadioGroup are leaving a black checked circle after I uncheck them or click on another RadioButton in the group. How do I prevent this from happening?

<RadioGroup
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <RadioButton
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Test"
            android:textAlignment="textStart"
            android:layoutDirection="rtl"
            android:layout_gravity="start"
            android:background="?android:selectableItemBackground"/>

        <RadioButton
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textAlignment="textStart"
            android:layoutDirection="rtl"
            android:layout_gravity="start"
            android:background="?android:selectableItemBackground"/>

</RadioGroup>

Happens on my API 19 real device, not my API 27

Edit:_________________________________________________

Have tried using a custom selector which doesn't work

<RadioGroup
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/qrmenu_toolbar"
        android:orientation="vertical">

<RadioButton
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Resume"
            android:layoutDirection="rtl"
            android:layout_gravity="start"
            android:drawablePadding="12dp"
            android:paddingStart="16dp"
            android:paddingTop="12dp"
            android:paddingEnd="16dp"
            android:paddingBottom="12dp"
            app:drawableLeftCompat="@drawable/ic_resume"
            android:button="@drawable/radiobutton_selector"

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

Theme:

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

Bump still can't find a solution

Have also tried using custom radio buttons.. still doesn't work:

<RadioButton
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:button="@drawable/custom_radio_button"/>

Custom RadioButton:

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

Answer 1

Remove the background from the radio button

android:background="?android:selectableItemBackground"

and use android:button="@drawable/radiobutton_selector"

Here is an example of a custom radio button in Android. please look into this. Maybe this help for you. http://www.apnatutorials.com/android/android-radiobutton-customization-and-usage.php?categoryId=2&subCategoryId=62&myPath=android/android-radiobutton-customization-and-usage.php

Answer 2

Use MaterialRadioButton from support library(com.google.android.material). The problem may occur because of different implementation of RadioButton depending on API version in conjunction with themes and selectors. Usage of MaterialRadioButton will unify behaviour across the API versions.

Here is a small give for this component.

'com.google.android.material:material:1.0.0' dependency should be imported to the project and one of Material themes used for the app.

Hope it will help.
