title: How to disable a tab in bottom navigation view?
body: <p>I have 4 tabs in my app. In which one is accessible without log-in but others can't be. So, I need to implement a functionality in which if a user clicks on that tab then rest 4 will be disabled and when I click on those tabs I only want toast but if I click on those tabs I get toast but it also got selected but fragment not changed. I want to disable that tab
  I have assigned a value to a variable to check whether it is without logging or after logging.</p>
  
  <p>Code:</p>
  
  <pre><code>  case R.id.home:
                  if(value.equals("1")){
                      Toast.makeText(CarerSeekerActivity.this,R.string.login_signup,Toast.LENGTH_SHORT).show();
                      navigation.getMenu().getItem(0).setEnabled(false);
  
                  }
                  else {
                      fragment = new CreatePersonalizedPackageCareSeekerFragment();
                      changeFragments(fragment);
                  }
                  return true;
  </code></pre>
