RelativeLayout is a layout manager in Android that allows you to position views relative to each other. It's a flexible layout that allows you to create complex layouts by specifying the position of child views relative to each other or the parent layout.
When we should use Relative Layout?
RelativeLayout in Android is a versatile layout that can be used to create complex UI designs. There are many cases where we can use the relative layout but are some scenarios where it can be useful:
When you need to position views relative to each other: RelativeLayout is ideal when you need to position views relative to each other, rather than specifying their positions using absolute coordinates. This allows you to create flexible layouts that can adapt to different screen sizes and orientations.
When you need to create complex layouts: If you need to create a layout that contains multiple views that are positioned in a specific way, RelativeLayout can make this task easier. It allows you to position views above or below each other, align them to the left or right edges of the screen, or center them horizontally or vertically.
Now here are some comman attributes that can be used in Relative Layout
android:layout_above: Positions the view above another view.android:layout_below: Positions the view below another view.android:layout_alignTop: Positions the top edge of the view to the top edge of another view.android:layout_alignBottom: Positions the bottom edge of the view to the bottom edge of another view.android:layout_alignLeft: Positions the left edge of the view to the left edge of another view.android:layout_alignRight: Positions the right edge of the view to the right edge of another view.android:layout_centerHorizontal: Centers the view horizontally in the parent layout.android:layout_centerVertical: Centers the view vertically in the parent layout.android:layout_centerInParent: Centers the view both horizontally and vertically in the parent layout.
