Did you find the answer?

[@onei3533]

found a solution just use if instead switch

[@alimishazwan3687]

binding.bottomNavigationView.setOnItemSelectedListener(item -> {
if (item.getItemId() == R.id.learn) {
replaceFragment(new LearnFragment());
} else if (item.getItemId() == R.id.game) {
replaceFragment(new GameFragment());
} else if (item.getItemId() == R.id.profile) {
replaceFragment(new ProfileFragment());
} else {
replaceFragment(new SettingFragment());
}
return true;
});
here the example to solve the problem. just use if statement

Everything went well, until the ActivityMainBinding. Good tutorial though.

[@castero465]

change it to name of the class next to name of xml activity Binding
for example if the xml file name is avtivity_editable the binding name will be ActivityEditableBinding not ActivityMainBinding

[@Mirtguitar]

@@castero465 Thank you mate, i had a typo in the binding name, now it works.

[@leychelle]

If your activity name is MainActivity then it will be ActivityMainBinding but for example if your activity name is LoginActivity it will be ActivityLoginBinding.
You have to call binding according to the activity with it's respective layout file

[@azlanahmed2811]

Set on click listener nhi call karna hai set on selected item method call hoga
