Learn About Java Listeners

The path to becoming a great Android developer is not straightforward. To make an application or modify an existing one, you need to know Java. To write a good application, you need to know all of the language’s nuances. Much of this information is available in resources found here on XDA. Applications written in Java use listeners, small functions that launch an activity when you press a certain part of the screen.

XDA Senior Member mohamedrashad wrote a useful guide to help new coders understand listeners better and learn how to use them. The guide explains how to define a button in Java, initialize it, and add a listener to launch the activity. You will also learn how to add Checkboxes and Radio buttons, and how to use them in groups. This is naturally just a small part of the Java language, but it can undoubtedly be useful for many—both newcomers just beginning their journey in Java an experienced coders looking for a refresher.

To learn more about depths of Java programming and how to use listeners in your app, head over to the guide thread.
