NestedRadioButton lets you have any number of ViewGroup intermediates between your RadioButton and RadioGroup. This allows to embed your RadioButton in more complex selectable views (examples in sample).

NestedRadioButton is available on Maven Central. To use in your project, simply add the following dependency to your app:

dependencies {
    ...
    implementation 'com.github.jbvincey:nestedradiobutton:1.1'
    ...
}

NestedRadioButton used to be available on JCenter under the package name com.jbvincey:nestedradiobutton. Due to JCenter shutdown, the NestedRadioButton library has been migrated to Maven Central with a different package name com.github.jbvincey:nestedradiobutton. If you were pulling the NestedRadioButton library from JCenter, make sure to add Maven Central repository in your configuration and to update the package name of NestedRadioButton library.

<com.jbvincey.nestedradiobutton.NestedLinearRadioGroup
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:checkedButton="@+id/radioButton1">

    <LinearLayout
        android:id="@+id/l1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <com.jbvincey.nestedradiobutton.NestedRadioButton
            android:id="@+id/radioButton1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:clickableParent="@+id/l1" />
...

In your layout, use one of the 4 nested ViewGroup implementation among :

• NestedLinearRadioGroup
• NestedConstraintRadioGroup
• NestedRelativeRadioGroup
• NestedFrameRadioGroup

Then you can use NestedRadioButton at any hierarchy level under your nested ViewGroup.

The app:checkedButton attribute in the nested ViewGroup allows to define the radio button checked by default in your layout. The app:clickableParent attribute in NestedRadioButton lets you define a parent ViewGroup that will check the RadioButton on click to this ViewGroup.
