Android - ConstraintLayout, RadioGroup and two columns of RadioButton

To create a layout with a ConstraintLayout, a RadioGroup, and two columns of RadioButtons in Android, you can use a combination of nested layouts and constraints. Here's how you can do it:

<?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <RadioGroup android:id="@+id/radioGroup" android:layout_width="0dp" android:layout_height="wrap_content" android:orientation="vertical" app:layout_constraintTop_toTopOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintEnd_toStartOf="@+id/guideline" app:layout_constraintBottom_toBottomOf="parent"> <RadioButton android:id="@+id/radioButton1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="RadioButton 1" /> <RadioButton android:id="@+id/radioButton2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="RadioButton 2" /> <!-- Add more RadioButtons as needed --> </RadioGroup> <androidx.constraintlayout.widget.Guideline android:id="@+id/guideline" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" app:layout_constraintGuide_percent="0.5" /> <RadioGroup android:id="@+id/radioGroup2" android:layout_width="0dp" android:layout_height="wrap_content" android:orientation="vertical" app:layout_constraintTop_toTopOf="parent" app:layout_constraintStart_toEndOf="@+id/guideline" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintBottom_toBottomOf="parent"> <RadioButton android:id="@+id/radioButton3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="RadioButton 3" /> <RadioButton android:id="@+id/radioButton4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="RadioButton 4" /> <!-- Add more RadioButtons as needed --> </RadioGroup> </androidx.constraintlayout.widget.ConstraintLayout>

In this layout:

  • Two RadioGroup elements are used, each representing a column of RadioButtons.
  • The Guideline is used to separate the two columns of RadioButtons horizontally.
  • Each RadioGroup is constrained to the top and bottom of the parent ConstraintLayout and to the start and end of the Guideline.
  • Each RadioButton is placed inside its respective RadioGroup.

Adjust the layout as needed and add more RadioButtons to each column as required.
