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:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/someItemNotToHide1"
        android:title="ITEM"
        app:showAsAction="always" />

    <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"/>

    <group android:id="@+id/overFlowItemsToHide">
    <item android:id="@+id/someID" 
    android:orderInCategory="1" app:showAsAction="never" />
    <item android:id="@+id/someID2" 
    android:orderInCategory="1" app:showAsAction="never" />
    <item android:id="@+id/someID3" 
    android:orderInCategory="1" app:showAsAction="never" />
    </group>
</menu>

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       
}

Try this   MenuItem myitem   menu findItem R id my item   myitem setVisible false

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

By setting the Visibility of all items in Menu  the appbar menu or overflow menu will be Hide automatically  Example  private Menu menu change language               Override public boolean onCreateOptionsMenu Menu menu                        menu change language   menu      menu change language findItem R id menu change language              setVisible true        return super onCreateOptionsMenu menu       Before going to other fragment use bellow code   if menu change language    null                        menu change language findItem R id menu change language          setVisible false

You can call this   MenuItem item   menu findItem R id my item   item setVisible false     Update   Make sure your code doesn t returns null for item or it may crash the application

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

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

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

Initially set the menu item visibility to false in the menu layout file as follows     lt  xml version  1 0  encoding  utf-8   gt   lt menu xmlns android  http   schemas android com apk res android      xmlns app  http   schemas android com apk res-auto  gt       lt item         android visible  false          android id    id action do something          android title   string txt do something          app showAsAction  always withText          android icon   drawable ic done   gt   lt  menu gt    You can then simply set the visibility of the menu item to false in your onCreateOptionsMenu   after inflating the menu    Override public void onCreateOptionsMenu Menu menu  MenuInflater inflater        super onCreateOptionsMenu menu  inflater       inflater inflate menu R menu menu       MenuItem item   menu findItem R id menuItemId       if  item    null           item setVisible false

didn t work for me  I had to explicitly use onPrepareOptionsMenu to set an item invisible   So use onCreateOptionsMenu to create the menu and onPrepareOptionsMenu to change visibility etc

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

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

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

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
