Hey guys welcome back to android developer course and the objective for this tutorial is to learn how we interact between the view and the java file that is the xml file and the java file.
when you click a button how you're going to interpret it and what you are going to do to the user as you can see we are able to create an application with a text and two buttons we have button one and button two so we are going to learn if you click button one we are going to perform an event when you click button two we are going to perform an event so uh to capture those events we should do it within our java file that is showing the content view of our activity for example

inside our activity we have button one and button two so i can just have this one go to my main activity

and have button
