I am using Navigation Bar + Fragments in my app.

Question

I am using Navigation Bar + Fragments in my app.

It is taking a lot of time in switching the fragments.
I am using this code ->
navigationView.setNavigationItemSelectedListener(
item -> {
item.setChecked(true);
drawerLayout.closeDrawers();
switch (item.getItemId()){
case R.id.places :
PlacesFragment fragment1 = new PlacesFragment();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.main_content, fragment1);
transaction.addToBackStack(null);
transaction.commit();
break;
case R.id.restaurants :
RestaurantsFragment fragment2 = new RestaurantsFragment();
FragmentTransaction transaction1 = getSupportFragmentManager().beginTransaction();
transaction1.replace(R.id.main_content, fragment2);
transaction1.addToBackStack(null);
transaction1.commit();
break;
case R.id.about :
AboutFragment fragment3 = new AboutFragment();
FragmentTransaction transaction2 = getSupportFragmentManager().beginTransaction();
transaction2.replace(R.id.main_content, fragment3);
transaction2.addToBackStack(null);
transaction2.commit();
break;
case R.id.hotels :
HotelsFragment fragment4 = new HotelsFragment();
FragmentTransaction transaction3 = getSupportFragmentManager().beginTransaction();
transaction3.replace(R.id.main_content, fragment4);
transaction3.addToBackStack(null);
transaction3.commit();
}

return true;
}
);
Is there any faster way to do that ?

Is there need to define 3 different transactions?? You could define only one transaction outside switch... And call it inside different cases

It looks like you posted long piece of code, consider editing it out and putting it on hastebin.com and pasting link to it instead. Alternatively, send your code in a file.
