For those using the Appcompat library   If your Activity subclasses ActionBarActivity  you can call supportInvalidateOptionsMenu    Seen here  https   stackoverflow com a 19649877 1562524

You are trying to access a menu item from an activity  which dont  have the access to scope  The call to find the menu item will return null  because the view is not binded with neither the activity nor the layout you are calling from   The menu items are binded with items such as  Navigation Bar  which in turn are binded with the corresponding activity    So initialize those views in activity     and then access the menu items withing that views    Navigation navView  navView   findViewById R id navigationView    MenuItem item   navView getMenu   findItem R id item hosting   item setVisible false

use invalidateOptionsMenu    in order to call onPrepareOptionsMenu menu  Menu       you should use onCreateOptionsMenu   only to create the initial menu state and not to make changes during the activity lifecycle         When an event occurs and you want to perform a menu update  you must call invalidateOptionsMenu   to request that the system call onPrepareOptionsMenu      https   developer android com guide topics ui menus

Create you menu options the normal way see code below and add a global reference within the class to the menu Menu mMenu      global reference within the class  Override public boolean onCreateOptionsMenu Menu menu        getMenuInflater   inflate R menu menu tcktdetails  menu       mMenu menu      assign the menu to the new menu item you just created      return true       Override public boolean onOptionsItemSelected MenuItem item        int id   item getItemId        if  id    R id action cancelticket            cancelTicket             return true             return super onOptionsItemSelected item      Now you can toggle your menu by running this code with a button or within a function if mMenu    null                    mMenu findItem R id action cancelticket  setVisible false

According to Android Developer Official site OnCreateOptionMenu Menu menu  is not recomended for changing menu items or icons  visibility  etc at Runtime   After the system calls onCreateOptionsMenu    it retains an instance of the Menu you populate and will not call onCreateOptionsMenu   again unless the menu is invalidated for some reason  However  you should use onCreateOptionsMenu   only to create the initial menu state and not to make changes during the activity lifecycle  If you want to modify the options menu based on events that occur during the activity lifecycle  you can do so in the onPrepareOptionsMenu   method  This method passes you the Menu object as it currently exists so you can modify it  such as add  remove  or disable items   Fragments also provide an onPrepareOptionsMenu   callback   --AndroidDeveloper Official Site --  As Recomended You can use this onOptionsItemSelected MenuItem item  method track user inputs   Override public boolean onOptionsItemSelected MenuItem item         int id   item getItemId         if  id    R id edit            Intent intent   new Intent this  ExampleActivity class           intent putExtra BUNDLE KEY  mConnection           startActivityForResult intent  PICK CHANGE REQUEST           return true        else if  id    R id delete            showDialog this           return true             return super onOptionsItemSelected item      If you need to change Menu Items at Run time  You can use onPrepareOptionsMenu Menu menu  to change them  Override public boolean onPrepareOptionsMenu Menu menu        if  Utils checkNetworkStatus ExampleActivity this             menu findItem R id edit  setVisible true           menu findItem R id delete  setVisible true        else           menu findItem R id edit  setVisible false           menu findItem R id delete  setVisible false             return true

Get a MenuItem pointing to such item  call setVisible on it to adjust its visibility and then call invalidateOptionsMenu   on your activity so the ActionBar menu is adjusted accordingly   Update  A MenuItem is not a regular view that s part of your layout  Its something special  completely different  Your code returns null for item and that s causing the crash  What you need instead is to do   MenuItem item   menu findItem R id addAction     Here is the sequence in which you should call  first call invalidateOptionsMenu   and then inside onCreateOptionsMenu Menu  obtain a reference to the MenuItem  by calling menu findItem    and call setVisible   on it

P1r4nh4 answer works fine  I just simplified it using a boolean flag   public int mState   0    at the top of the code   where you want to trigger the hide action mState   1     to hide or mState   0  to show invalidateOptionsMenu       now onCreateOptionsMenu      is called again       Override public boolean onCreateOptionsMenu Menu menu           inflate menu from xml     MenuInflater inflater   getSupportMenuInflater        inflater inflate R menu settings  menu        if  mState    1    1 is true  0 is false                 hide only option 2             menu getItem 2  setVisible false

Found an addendum to this question   If you want to change the visibility of your menu items on the go you just need to set a member variable in your activity to remember that you want to hide the menu and call invalidateOptionsMenu   and hide the items in your overridden onCreateOptionsMenu      method     anywhere in your code     mState   HIDE MENU     setting state invalidateOptionsMenu       now onCreateOptionsMenu      is called again       Override public boolean onCreateOptionsMenu Menu menu           inflate menu from xml     MenuInflater inflater   getSupportMenuInflater        inflater inflate R menu settings  menu        if  mState    HIDE MENU                for  int i   0  i  lt  menu size    i                menu getItem i  setVisible false             In my example I ve hidden all items

I think a better approach would be to use a member variable for the menu  initialize it in onCreateOptionsMenu   and just use setVisible   afterwards  without invalidating the options menu

The best way to hide all items in a menu with just one command is to use  group  on your menu xml  Just add all menu items that will be in your overflow menu inside the same group   In this example we have two menu items that will always show  regular item and search  and three overflow items    lt menu xmlns android  http   schemas android com apk res android      xmlns app  http   schemas android com apk res-auto  gt        lt item         android id    id someItemNotToHide1          android title  ITEM          app showAsAction  always    gt        lt item         android id    id someItemNotToHide2          android icon   android drawable ic menu search          app showAsAction  collapseActionView ifRoom          app actionViewClass  android support v7 widget SearchView          android title  Search   gt        lt group android id    id overFlowItemsToHide  gt       lt item android id    id someID       android orderInCategory  1  app showAsAction  never    gt       lt item android id    id someID2       android orderInCategory  1  app showAsAction  never    gt       lt item android id    id someID3       android orderInCategory  1  app showAsAction  never    gt       lt  group gt   lt  menu gt    Then  on your activity  preferable at onCreateOptionsMenu   use command setGroupVisible to set all menu items visibility to false or true   public boolean onCreateOptionsMenu Menu menu       menu setGroupVisible R id overFlowItems  false      Or true to be visible     If you want to use this command anywhere else on your activity  be sure to save menu class to local  and always check if menu is null  because you can execute before createOptionsMenu   Menu menu   public boolean onCreateOptionsMenu Menu menu           this menu   menu      public void hideMenus            if  menu    null  menu setGroupVisible R id overFlowItems  false      Or true to be visible

set a value to a variable and call invalidateOptionsMenu     for example      selectedid arg2              invalidateOptionsMenu       public boolean onPrepareOptionsMenu Menu menu         if selectedid  1           menu findItem R id action setting  setVisible false           menu findItem R id action s2  setVisible false           menu findItem R id action s3  setVisible false             else          if selectedid  2               menu findItem R id action search  setVisible false               menu findItem R id action s4  setVisible false               menu findItem R id action s5  setVisible false                       return super onPrepareOptionsMenu menu

If you did everything as in above answers  but a menu item is still visible  check that you reference to the unique resource  For instance  in onCreateOptionsMenu or onPrepareOptionsMenu   Override public void onPrepareOptionsMenu Menu menu        super onPrepareOptionsMenu menu       MenuItem menuOpen   menu findItem R id menu open       menuOpen setVisible false       Ctrl Click R id menu open and check that it exists only in one menu file  In case when this resource is already used anywhere and loaded in an activity  it will try to hide there
