How do I use an event to return true in an if condition in Java

I am new to Java and I am making an app where I need to have multiple containers do the same kind of thing. What I plan to do is use the event objects to find out which one was selected and then call the same function. I don’t have any code at the moment.
How would I use the event object to do so? Or is there a better way?

Pascal case not accepted for binding data variable name in kotlin in android studio

here’s my data

          type="com.example.practice.MyName" />

here’s the MainActivity

class MainActivity : AppCompatActivity() {
    lateinit var binding: ActivityMainBinding
    private val name:MyName = MyName("hello")
    override fun onCreate(savedInstanceState: Bundle?) {
        binding = DataBindingUtil.setContentView(this,R.layout.activity_main)
        binding.Name = name
        binding.button.setOnClickListener { change(it) }

I get error "Unresolved reference: Name"at binding.Name = name

It works perfectly fine when I set name to any name of Camel case i.e.,starting with small letter, but it doesn’t work for the name starting with capital letters.
Why ?

When I run Android project all components land on top of each other

I’m very new to Android Studio and I’m trying to make my 1st app, where you enter 2 numbers and it adds them together. I’m having an issue with all the view components, because in studio, they look fine, but when I run it on my phone, all the components land on top of each other, as you can see in the image. As I said, I’m very new to Android, so I’m probably making a stupid mistake.Thanks for helping!
