I'm new to Android studio.I'm using firestore recyclerview adapter to display list a of leagues after a user signs in; however, the recyclerview of Leaguelist activity isn't showing any items. It only shows the list of leagues when I try to add another league using floatingActionButton(still using the same activity). Then if I move on to the next activity then go back to the Leaguelist activity, I don't see any of league items unless I try to add another league again.
public class LeagueListActivity extends AppCompatActivity implements LeagueRecycleAdapter.OnItemClickListener{
List<League> leagueList;
LeaguesRepository leaguesRepository = new LeaguesRepository();
ListView listView;
LeagueAdapter adapter;
CheckBox checkBox;
static final int GET_LEAGUE_NAME = 1;
FloatingActionButton btnAddLeague;
private CoordinatorLayout coordinatorLayout;

setContentView(R.layout.activity_league_recycleview);

btnAddLeague.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivityForResult(new Intent
(LeagueListActivity.this,
EditNameActivity.class), GET_LEAGUE_NAME);
}
});
// hide the title of this activity

}else{

}
}
if (resultCode == Activity.RESULT_CANCELED) {
//Write your code if there's no result
