How to get SelectedItemId of BottomNavigationView in android
0
I have implemented BottomNavigationView in my app. Everything going easy and perfect but there is one problem i.e. on back press I want to get the currently active tab selected but now selected tab does not change when back press. Fragment changes but tab selection does not change. How can I detect the current tab and change the selected tab on back press. I tried a lot of things to do but not able to get selected tab ID.Please help.
Code:
int i = getSelectedItem(bottomNavigationView);
Log.e("TAG", "onCreate:tab "+i );
private int getSelectedItem(BottomNavigationView bottomNavigationView){
Menu menu = bottomNavigationView.getMenu();
for (int i=0;i<bottomNavigationView.getMenu().size();i++){
MenuItem menuItem = menu.getItem(i);
if (menuItem.isChecked()){
return menuItem.getItemId();
}
}
return 0;
}

take a global variable for id and update it when your select the tab from BottomNavigationView. hence when you press back button it will give you last selected tab item id.

If you want to find the checked item id, try this:
int checkedItemId = bottomNavigationView.getSelectedItemId();
To change current selected item, use this:
bottomNavigationView.getMenu().findItem(R.id.target_item_nemu).setChecked(true);

If I understand correctly, you want to show home fragment in onBackPressed if another fragment is showing, else (if the home fragment is the currently showing), exit the app. Right?
