ConstraintRadioGroup

This is a custom RadioGroup library that inherits from ConstraintLayout. You can use ConstraintLayout attributes, easily changing text font and color for checked/unchecked statuses. RadioGroup uses CompoundButton so you can use RadioButton as well as CheckBox components.

Usage

Gradle

dependencies {
    implementation 'com.wayne:constraint-radiogroup:1.0.0'
}
