I need some help with this, please. I'm using Android Studio.

Your application will be very similar to your Module 2 application. You need to implement an event handler for the "LOGIN" button. When user clicks on the button, you will validate the username and password fields. For testing purpose, you will hard code the correct username and password as "test". If user enters "test" for username and password, you will display a "Success" message and a "Failed" message otherwise.

As a review, to compare strings in Java, use the "equals" method: if ( userName.equals("test")&& password.equals("test")) { //success else { // failed
