It is not obligatory to create the separate class MyHandlers and call setHandlers for processing android:onClick. You can just use the methods: public void onClickFriend(View view) and public void onClickEnemy(View view) in MainActivity. The activity view:

public class MainActivity extends AppCompatActivity {
    User user;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ActivityMainBinding binding =
                DataBindingUtil.setContentView(this, R.layout.activity_main);
        user = new User("Pankaj", "Kumar", true, true);
        binding.setUser(user);
    }

    public void onClickFriend(View view) {
        Log.i(MyHandlers.class.getSimpleName(), "Now Friend");
    }

    public void onClickEnemy(View view) {
        Log.i(MyHandlers.class.getSimpleName(), "Now Enemy");
    }
}
