RelativeLayout

RelativeLayout is a layout where the positions of the children can be described in relation to each other or to the parent.

1. Ensure to change the minSDKVersion to 8, or greater if using match_parent. If using the deprecated, fill_parent, any API level will work.

2. In your main.xml file, add the following code for a RelativeLayout.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

</RelativeLayout>

3. Compile and run!
