I have a fragment with that needs to build its own action bar :
public class CalendarFragment extends Fragment {
public CalendarFragment() {
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
getActivity().supportInvalidateOptionsMenu();
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.calendar_menu1, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
TextView textView = new TextView(getActivity());
textView.setGravity(Gravity.CENTER);
textView.setText("Calendar Fragment");
return textView;
}
}
the problem is it doesnt create a new menu with items from calendar_menu1 but just adds the items from it to the old menu, as if invalidateOptionsMenu doesnt work (i tried getActivity().invalidateOptionsMenu() too)
You must call in onCreate():
setHasOptionsMenu(true);
It is normal, looking into the javadoc of the MenuInflater, "The items and submenus will be added to this Menu":
public void inflate (int menuRes, Menu menu)
Inflate a menu hierarchy from the specified XML resource. Throws InflateException if there is an error.
Parameters
menuRes Resource ID for an XML layout resource to load (e.g., R.menu.main_activity)
menu The Menu to inflate into. The items and submenus will be added to this Menu.
Did you try to call menu.clear() before to inflate your fragment menu?
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
menu.clear();
inflater.inflate(R.menu.calendar_menu1, menu);
}

I have a rare problem. I have an activity that has tabs populated dynamically (up to 20 tabs). Each fragment has an implementation of OnCreateOptionsMenu and a menu which contains a bookmark icon that changes color when pressed. There is a class variable menu of type Menu which is set when fragment's OnCreateOptionsMenu is called. This is to enable me set the bookmark menu item outside the onCreateOptionsMenu(This is also done dynamically).
Problem:
When the parent activity have only a single tab(One fragment instance), this implementation works fine. However with more than one tab, the app crashes with the error:
Attempt to invoke interface method android.view.MenuItem android.view.Menu.findItem(int)
What I think: I think the problem is that the OnCreateOptionsMenu is called once i.e Class variable: menu is set only once for the first tab (fragment) hence when other tabs are added, menu is null
Some codes:
Fragment
Menu menu;
...
...
#Override
public View onCreateView(#NonNull LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setMenuBookmark(ques_obj);
}
private void setMenuBookmark(QuestionAnswerList ques_obj){
MenuItem menuBookmark = this.menu.findItem(R.id.action_bookmark);
if (ques_obj.getIs_bookmarked().equals("1")) {
menuBookmark.setIcon(R.drawable.ic_bookmark_white_24dp);
} else {
menuBookmark.setIcon(R.drawable.ic_bookmark_border_white_24dp);
}
}
...
...
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.cbt_fragment_menu, menu);
this.menu = menu;
super.onCreateOptionsMenu(menu, inflater);
}
P.S setHasOptionsMenu() is set to true in Fragment's OnCreate
Try this way
#Override
public View onCreateView(#NonNull LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
getActivity().invalidateOptionsMenu()
}
}, 500 );
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.cbt_fragment_menu, menu);
MenuItem menuBookmark = menu.findItem(R.id.action_bookmark)
if (ques_obj.getIs_bookmarked().equals("1")) {
menuBookmark.setIcon(R.drawable.ic_bookmark_white_24dp);
} else {
menuBookmark.setIcon(R.drawable.ic_bookmark_border_white_24dp);
}
return true;
}
I'm trying to disable the MenuItem's in my navigationdrawer from my
fragment, but it just wont work...
Fragment code:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.waiting_for_terminal, container, false);
setHasOptionsMenu(true);
return rootView;
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.activity_main_drawer, menu);
menu.findItem(R.id.nav_amount).setEnabled(false);
menu.findItem(R.id.nav_return).setEnabled(false);
menu.findItem(R.id.nav_about).setEnabled(false);
menu.findItem(R.id.nav_settings).setEnabled(false);
super.onCreateOptionsMenu(menu, inflater);
}
I can call getTitle() for the MenuItems, and it will return correct value. But for some reason setEnabled(), setTitle(), setVisible() etc. does not work, the value stays the same...
to disable menuitem in fragment use it with fragment:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(false);
}
Remove onCreateOptionsMenu() inside the Activity,and use inside a fragment as:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.main, menu);
}
Try This:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
oldDescription= ActivityConstantUtils.sBlogDescriprtion;
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_act_add_section, menu);
MenuItem item = menu.findItem(R.id.action_preview);
item.setIcon(null);
item.setTitle("");
super.onCreateOptionsMenu(menu, inflater);
}
I think you are trying to disable that Home Button on the AppBar which toggles the NavigationDrawer.
The best way i can think of doing that is:
In Method onOptionItemSelected:
protected onOptionItemSelected(MenuItem item)
{
if(item.getItemId() == android.R.id.home)
{
// do anything you want here
}
}
This will help you override that Home Button.
More over if you want to replace that Hamburger Icon with an Default Arrow Icon, you can use
mNavigationDrawer.setDrawerIndicatorEnabled(false);
Additionally if you want to disable the drawer Swipe Functionality also,
you can use
drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
Hope it Helps. :)
Omg, my bad...
It was MenuItems in the NavigationView I wanted to disable...
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.getMenu().findItem(R.id.nav_amount).setEnabled(false);
Thanks for the help though :)
I want to load another menu xml when I load the fragment.I am using this code in main activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
I am using this code in fragment:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu,MenuInflater inflater) {
getActivity().getMenuInflater().inflate(R.menu.fragment_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
When user loads the fragment,activity menu should remove then fragment menu should load to actionbar.
And when user clicks the back button from fragment,fragment menu should remove then main activity menu should load to action bar.
Now this code is not removing the old menu,it's adding new menu to near of old menu.
How can I do this ?
You Can use menu.clear(); method.
It remove all existing items from the menu, leaving it empty as if it had just been created.
Try this..
#Override
public void onCreateOptionsMenu(Menu menu,MenuInflater inflater) {
menu.clear(); // clears all menu items..
getActivity().getMenuInflater().inflate(R.menu.fragment_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
You Should call setHasOptionsMenu(true); method in onCreateView.
It tells fragment got a menu.
Then Try below codes...
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
setHasOptionsMenu(true);
return inflater.inflate(R.layout.fragment_manage, container, false);
}
#Override
public void onCreateOptionsMenu(Menu menu,MenuInflater inflater) {
menu.clear(); // clears all menu items..
inflater.inflate(R.menu.fragment_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
Try this:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.fragment_menu, menu);
super.onCreateOptionsMenu(menu,inflater);
}
Hope it helps
I using menu drawer which has more Fragments. In some Fragments I have menu item REFRESH but in some fragments I want hide this menu item (I don't want show menu but I don't want hide ActionBar).
I try add override onCreateOptionsMenu() to Fragment where I don't want show this menu item but I can not get it to work. I try many way see commented line in code. Does any idea where is problem? And last this menu item go to hide when I activate menu drawer when is called onPrepareOptionsMenu() in MainActivity but I need do this when I'm in Fragment.
Fragment where I want hide menu item REFRESH:
public class FindPeopleFragment extends Fragment {
public FindPeopleFragment(){}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_find_people, container, false);
//setHasOptionsMenu(false);
return rootView;
}
private Menu menu=null;
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
inflater.inflate(R.menu.main, menu);
this.menu=menu;
menu.findItem(R.id.refresh).setVisible(false);
getActivity().invalidateOptionsMenu();
//setHasOptionsMenu(false);
super.onCreateOptionsMenu(menu,inflater);
}
}
MainActivity where is defined MENU DRAWER:
//Slide menu item click listener
private class SlideMenuClickListener implements
ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// display view for selected nav drawer item
displayView(position);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// toggle nav drawer on selecting action bar app icon/title
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
switch (item.getItemId()) {
case R.id.refresh:
Toast.makeText(this, "Refreshing data...", Toast.LENGTH_SHORT).show();
return true;
}
return super.onOptionsItemSelected(item);
}
// Called when invalidateOptionsMenu() is triggered
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
// if nav drawer is opened, hide the action items
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.refresh).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
In the fragment where you want to hide the Item
#Override
public void onPrepareOptionsMenu(Menu menu) {
MenuItem item=menu.findItem(R.id.action_search);
if(item!=null)
item.setVisible(false);
}
and in onCreate() of your fragment
setHasOptionsMenu(true);
In the Fragment where you don't want to show any menu options, you need setHasOptionsMenu(false); in the onCreate(), like this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(false);
}
However, the menu that is being shown that you would like to hide (REFRESH), belongs to MainActivity. That is why it is always shown. Since you want to control the menu at the Fragment level (and not show an Activity options menu), my suggestion is to delete the menu code from the Activity and implement it in your Fragment.
Activitys and Fragments can each have their own separate menus. See this link.
please try this
#Override
public void onPrepareOptionsMenu(Menu menu) {
menu.clear();
}
and put this on your fragmen's onCreate()
setHasOptionsMenu(true);
In Fragment Class
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
menu.clear();
}
in Kotlin for those who needs it
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setHasOptionsMenu(true)
}
override fun onPrepareOptionsMenu(menu: Menu) {
super.onPrepareOptionsMenu(menu)
menu.clear()
}
I used the code below for hiding menu items in a fragment where I don't want to use it.
Note: Please read comment
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
Fragment whichFragment=getVisibleFragment();//getVisible method return current visible fragment
String shareVisible=whichFragment.getClass().toString();
if(shareVisible.equals(AccFragment.class.toString())
||shareVisible.equals(SocFragment.class.toString())
||shareVisible.equals(DevFragment.class.toString())
){
MenuItem item=menu.findItem(R.id.action_share);
item.setVisible(false);
}
return super.onCreateOptionsMenu(menu);
}
in Kotlin
override fun onPrepareOptionsMenu(menu: Menu) {
val item: MenuItem = menu.findItem(R.id.action_search)
item.isVisible = false
}
in onCreate() of your fragment
setHasOptionsMenu(true)
There are many different versions of similar solutions but unfortunately, none of them worked for me. I am sharing what eventually was useful for me to hide the whole overflow menu with multiple menu items. Thought maybe it's useful for anyone.
I grouped my menus with an id and then referred that id
#Override
public void onPrepareOptionsMenu(Menu menu) {
menu.setGroupVisible(R.id.menu_overflow, false);
super.onPrepareOptionsMenu(menu);
}
If you want to hide any individual menu item then you can use
menu.getItem(R.id.action_licenses).setVisible(false);
Important thing is that you should have setOptionsMenu(true) in onViewCreated()
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
setHasOptionsMenu(true);
Call setHasOptionMenu(true) in onCreateView()
and Do not call super.onCreateOptionsMenu() in fragment's onCreateOptionMenu() instead call menu.clear() because this will override the existing menu with the activity's menu
This worked in my case.
Or solve it in the same Fragment which created the menu, if you host the Actionbar on Activity level. This way you don't have to add it on every other Fragment where you don't want to show it:
public override void OnDestroy()
{
base.OnDestroy();
HasOptionsMenu = false;
}
Add these functions to your Fragment
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onPrepareOptionsMenu(Menu menu) {
MenuItem item=menu.findItem(R.id.delete);
item.setVisible(false);
}
Firstly in your Activity that has the toolbar, create a method that sets up the overflow menu for you:
public void setUpOptionMenu(Toolbar toolbar){
this.setSupportActionBar(toolbar);
}
In your fragments onCreateView() method, get the reference of your current activity and call your activities setUpOptionMenu() method:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
...
...
public void ((YourActivityName)this.getActivity()).setUpOptionMenu(null);
...
...
}
Cheers!!!
Overrride the following method just in your fragment and it will do the trick.
#Override
public void onCreateOptionsMenu(Menu menu,MenuInflater inflater) {
// Do something that differs the Activity's menu here
getActivity().getMenuInflater().inflate(R.menu.drawer, menu);
}

On your activity, where you navigate to fragments, You can try like below, On below code, Tested on Side Navigation view, It has been shown wherever needed using toolbar.inflateMenu(R.menu.toolbar_menu) and hidden using toolbar.menu.clear() on toolbar reference.
binding.naviSideNav.setNavigationItemSelectedListener(NavigationView.OnNavigationItemSelectedListener {
when (it.itemId) {
R.id.side_nav_home->{
toolbar.title=""
toolbar.menu.clear()
toolbar.inflateMenu(R.menu.toolbar_menu)
toolbar.setBackgroundColor(ContextCompat.getColor(this,R.color.home_screen_bg))
navController.navigate(R.id.navigation_home)
}
R.id.side_nav_appointments->{
}
R.id.side_nav_ehr->{
}
R.id.side_nav_invoices->{
}
R.id.side_nav_settings->{
toolbar.title=getString(R.string.nav_menu_Settings)
toolbar.menu.clear()
toolbar.setBackgroundColor(ContextCompat.getColor(this,R.color.home_screen_bg))
navController.navigate(R.id.navigation_settings)
}
R.id.side_nav_logout->{
}
}
binding.dlt.closeDrawer(GravityCompat.START)
true
})
Clean and redraw menu item
override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
menu.clear()
inflater.inflate(R.menu.main_menu, menu)
menu.findItem(R.id.id_menu_search)?.isVisible = true
super.onCreateOptionsMenu(menu, inflater)
}
I have checked the answers but now the optionMenu has been deprecated in the latest Android api level
setHasOptionsMenu(false)
so for the people who are using MenuProvider for optionMenu can use the
setMenuVisibility(false)
like this in fragment
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setMenuVisibility(false)
}
Just find the item you want to hide using findItem then set its visibility to false.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
MenuItem item = menu.findItem(R.id.action_settings);
item.setVisible(false);
}
I have placed setHasOptionsMenu(true) inside onCreateView, but I still can't call onCreateOptionsMenu inside fragments.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setHasOptionsMenu(true);
return inflater.inflate(R.layout.facesheet, container, false);
}
Below is my onCreateOptionsMenu code.
#Override
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
getSupportMenuInflater().inflate(R.menu.layout, menu);
return (super.onCreateOptionsMenu(menu));
}
The error message I get:
The method onCreateOptionsMenu(Menu) of type Fragment must override or implement a supertype method.
try this,
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_sample, menu);
super.onCreateOptionsMenu(menu,inflater);
}
Finally, in onCreateView method, add this line to make the options appear in your Toolbar
setHasOptionsMenu(true);
Your already have the autogenerated file res/menu/menu.xml defining action_settings.
In your MainActivity.java have the following methods:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (id) {
case R.id.action_settings:
// do stuff, like showing settings fragment
return true;
}
return super.onOptionsItemSelected(item); // important line
}
In the onCreateView() method of your Fragment call:
setHasOptionsMenu(true);
and also add these 2 methods:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.fragment_menu, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (id) {
case R.id.action_1:
// do stuff
return true;
case R.id.action_2:
// do more stuff
return true;
}
return false;
}
Finally, add the new file res/menu/fragment_menu.xml defining action_1 and action_2.
This way when your app displays the Fragment, its menu will contain 3 entries:
action_1 from res/menu/fragment_menu.xml
action_2 from res/menu/fragment_menu.xml
action_settings from res/menu/menu.xml
I tried the #Alexander Farber and #Sino Raj answers. Both answers are nice, but I couldn't use the onCreateOptionsMenu inside my fragment, until I discover what was missing:
Add setSupportActionBar(toolbar) in my Activity, like this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.id.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
I hope this answer can be helpful for someone with the same problem.
Call
setSupportActionBar(toolbar)
inside
onViewCreated(...)
of Fragment
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
((MainActivity)getActivity()).setSupportActionBar(toolbar);
setHasOptionsMenu(true);
}
Set setHasMenuOptions(true) works if application has a theme with Actionbar such as Theme.MaterialComponents.DayNight.DarkActionBar or Activity has it's own Toolbar, otherwise onCreateOptionsMenu in fragment does not get called.
If you want to use standalone Toolbar you either need to get activity and set your Toolbar as support action bar with
(requireActivity() as? MainActivity)?.setSupportActionBar(toolbar)
which lets your fragment onCreateOptionsMenu to be called.
Other alternative is, you can inflate your Toolbar's own menu with toolbar.inflateMenu(R.menu.YOUR_MENU) and item listener with
toolbar.setOnMenuItemClickListener {
// do something
true
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_add_customer, container, false);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_sample, menu);
super.onCreateOptionsMenu(menu,inflater);
}
You can do easily as,
inside your fragment on Create method,
setHasOptionsMenu(true)
and now you can override,
override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
super.onCreateOptionsMenu(menu, inflater)
menu.clear()
}
