Android Tutorial => Binding Listeners using ButterKnife

Example

OnClick Listener:

@OnClick(R.id.login)
public void login(View view) {
  // Additional logic
}

All arguments to the listener method are optional:

@OnClick(R.id.login)
public void login() {
   // Additional logic
}

Specific type will be automatically casted:

@OnClick(R.id.submit)
public void sayHi(Button button) {
  button.setText("Hello!");
}

Multiple IDs in a single binding for common event handling:

@OnClick({ R.id.door1, R.id.door2, R.id.door3 })
public void pickDoor(DoorView door) {
  if (door.hasPrizeBehind()) {
    Toast.makeText(this, "You win!", LENGTH_SHORT).show();
  } else {
    Toast.makeText(this, "Try again", LENGTH_SHORT).show();
  }
}

Custom Views can bind to their own listeners by not specifying an ID:

public class CustomButton extends Button {
  @OnClick
  public void onClick() {
    // TODO 
  }
}
