public class Example12
extends java.lang.Object

This example illustrates the BASELINE alignment to align comoponents which contain text. This example is taken from an article on Relative Layout. Without the use of BASELINE alignment in the top level cell, the text on the label Sample Text and the check box Strikethrough would not be properly aligned.
