Handling User Input
Respond to button clicks, read text from EditText, validate input, and provide user feedback with Toast messages.
Connecting UI to Code
Building a layout is just the first step. You also need to:
- Read what the user typed in an EditText
- Respond to button clicks
- Update TextViews with new values
This lesson shows how to wire up UI elements using ViewBinding — the modern, type-safe approach.
Enabling ViewBinding
Enable ViewBinding in your app/build.gradle:
// app/build.gradle (inside android { })
android {
...
buildFeatures {
viewBinding = true
}
}
