Kako napraviti da objekti u rasporedu budu raspoređeni u krug?

Za raspoređivanje objekata u krug možete koristiti ConstraintLayout sa Circular positioning.

<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/center_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Centar"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"/>

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Dugme 1"
        app:layout_constraintCircle="@+id/center_view" // ID centralnog elementa
        app:layout_constraintCircleRadius="150dp" // Poluprečnik kruga
        app:layout_constraintCircleAngle="0" /> // Ugao u stepenima (0° - desno)

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Dugme 2"
        app:layout_constraintCircle="@+id/center_view"
        app:layout_constraintCircleRadius="150dp"
        app:layout_constraintCircleAngle="90" /> // 90° - dole

    <Button
        android:id="@+id/button3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Dugme 3"
        app:layout_constraintCircle="@+id/center_view"
        app:layout_constraintCircleRadius="150dp"
        app:layout_constraintCircleAngle="180" /> // 180° - levo

    <Button
        android:id="@+id/button4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Dugme 4"
        app:layout_constraintCircle="@+id/center_view"
        app:layout_constraintCircleRadius="150dp"
        app:layout_constraintCircleAngle="270" /> // 270° - gore

</androidx.constraintlayout.widget.ConstraintLayout>

Atributi za kružno pozicioniranje:

Atribut	Opis
app:layout_constraintCircle	ID elementa oko kojeg se gradi krug.
app:layout_constraintCircleRadius	Poluprečnik kruga u dp.
app:layout_constraintCircleAngle	Ugao u stepenima (0° - desno od centra, povećava se u smeru suprotno od kazaljke na satu).
