I have a RadioGroup that will be populated programmatically (I'm using kotlin) and I want to change the circle color of the radio button (try to avoid the accent color solution).

** XML

<RadioGroup
    android:id="@+id/radio_group"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="8dp" />

** Kotlin

for (entry in entries) {

    val rb = RadioButton(applicationContext)

    rb .text = entry
    rb .id = entries.indexOf(entry) + 100
    rb .setTextColor(Color.BLACK)
    rb .isChecked = (entries.indexOf(entry) == 0)

    rbg.addView(rb)
}

  • IT works fine for api > 21 but I consider api 16 – Mohamed Jihed Jaouadi Feb 07 '20 at 08:35

You can use 

android:buttonTint="your color"

For API<21

app:buttonTint="your color"

to change the color of circle in RadioButton
