you are trying to instantiate MainActivityOderLIstFargmant activity in the switch case R.id.nav_home and put it into a Fragment variable which is called selectedFragment, so both types are different (Fragment & Activity). That is why the screenshot you provided says Incompatible types.

To get your code works you can change the switch case as below

case R.id.nav_home:
    Intent intent = new Intent(NafMaintest.this, MainActivityOderLIstFargmant.class);
    startActivity(intent);
    return true; // use return to avoid triggering the fragment transaction after the `swtich` block
