What is the difference between using RelativeLayout and LinearLayout in Android development?

LinearLayout and RelativeLayout are two different types of ViewGroup in Android that manage the arrangement of child elements.

• LinearLayout arranges child elements in a single row — vertically or horizontally. All elements are placed one after another, and you can set a weight to distribute free space.

• RelativeLayout allows positioning elements relative to each other or relative to the parent container. For example, you can specify that one element should be to the right of another or centered.

Example:

<!-- LinearLayout with vertical orientation -->
<LinearLayout
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <Button android:text="Button 1" />
    <Button android:text="Button 2" />
</LinearLayout>

<!-- RelativeLayout with positioning -->
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <Button
        android:id="@+id/button1"
        android:text="Button 1"
        android:layout_alignParentLeft="true" />
    <Button
        android:text="Button 2"
        android:layout_toRightOf="@id/button1" />
</RelativeLayout>

Summary: LinearLayout is simpler for sequential arrangement, while RelativeLayout is more flexible for complex layouts where elements need to be positioned relative to each other.
