change automatically select for bottonavigation selected

Question

I'm working on this code

private void setupViews(){
    frameLayout = (FrameLayout) findViewById(R.id.frame_id);
    bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottom_nav_id);
    getSupportFragmentManager().beginTransaction().replace(R.id.frame_id,new ProfileFragment()).commit();
}

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
    int navID = menuItem.getItemId();
    switch (navID){
        case R.id.home:
            getSupportFragmentManager().beginTransaction().replace(R.id.frame_id,new HomeFragment()).commit();
            break;
        case R.id.search:
            getSupportFragmentManager().beginTransaction().replace(R.id.frame_id,new SearchFragment()).commit();
            break;
        case R.id.profile:
            getSupportFragmentManager().beginTransaction().replace(R.id.frame_id,new ProfileFragment()).commit();
            break;
    }
    return true;
}

When I launch my app, it's automatically going on first bottom (I have 3 bottoms) I want to change this to second bottom in navigation view. Please help me

"it's automatically going on first bottom (I have 3 bottoms)" When you say "bottom" what are you referring to? It looks like your code is trying to go the the `ProfileFragment` on startup. Is this what you want? — ChrisMcJava, Apr 02 '20 at 02:07

Try this:

bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottom_nav_id);
bottomNavigationView.setSelectedItemId(R.id.search);
getSupportFragmentManager().beginTransaction().replace(R.id.frame_id,new SearchFragment()).commit();
