}
Layout XML
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

<variable
name="handler"
type="com.example.ClickHandler"/>
</data>
<RelativeLayout

<Button
android:layout_width="wrap_content"

Handle event in your Activity
public class MainActivity extends Activity implements ClickHandler {
private ActivityMainBinding binding;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = DataBindingUtil.setContentView(this,R.layout.activity_main);
binding.setHandler(this);
}
@Override
public void onButtonClick(View v) {
Toast.makeText(context,"Button clicked",Toast.LENGTH_LONG).show();
}
}
