Answer 1

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
