One of the most used layout managers in Android programming is RelativeLayout.
It offers a versatile technique to position UI items in relation to one another or to the parent container. This enables the development of intricate and dynamic user interfaces.
Each view in a RelativeLayout is placed according to how it relates to other views.
Several properties, including alignParentTop, alignParentBottom, alignLeft, alignRight, and others, are used to do this. We can design user interfaces (UIs) that adjust to various screen sizes and orientations by establishing these relationships.
Let’s look at an example to see how RelativeLayout is used. Consider a straightforward form that consists of a TextView, an EditText, and a Button. The TextView and Button should be positioned above and below the EditText, respectively.
Implementation in XML:
To utilize RelativeLayout, define it in XML layout files using the following syntax:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp"
tools:context=".MainActivity">
<!-- All Child views here -->
</RelativeLayout>
This may be done by giving each view in the RelativeLayout the proper layout properties.
The views will be dynamically positioned based on their relationships by utilising these layout parameters. This implies that the other views would automatically adjust if we were to modify the size or position of any view.
In Relative layout we can use other child view like Linearlayout or constrain layout or many other options.
RelativeLayout is especially flexible and gives a wide range of options.
RelativeLayout allows you to centre an element on the screen, centre it on the left, centre it in the middle of the screen, and more.
Because every child view is drawn by default at the top-left of the layout, you must specify each view’s location using one of the available layout attributes.
