getSupportMenuInflater().inflate(R.menu.main, menu);
SubMenu subMenu = (SubMenu) menu.getItem(0).getSubMenu();

subMenu.getItem(1).setVisible(false);
return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId()) {
case R.id.Profile:
break;
case R.id.changePword :

How to Dynamically Add Menu Items to an Android Activity. The following specific example adds a MENU_LOGOUT option if the user is logged in. private static final int MENU_LOGOUT = MENU. FIRST + 4; public boolean onPrepareOptionsMenu(Menu menu) { ... if(auth.
On the Navigation page, click the title of the menu that you want to edit. Click Add menu item. Enter a name for the menu item. This name displays in the menu, and can include special characters or emoji.
The Dynamic Menu is a modified concept of the Menu component, used when the number of actions available to the user is dynamic or variable. It can also be useful when the number of actions in the menu is large enough that a search functionality would be required.
Inside the onCreateContextMenu() callback method, you can add menu items using one of the add() methods, or by inflating a menu resource that was defined in XML. Then, register a ContextMenu for the View, with registerForContextMenu() .
Try the following way.
@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, 0, 0, "Option1").setShortcut('3', 'c');
menu.add(0, 1, 0, "Option2").setShortcut('3', 'c');
menu.add(0, 2, 0, "Option3").setShortcut('4', 's');
SubMenu sMenu = menu.addSubMenu(0, 3, 0, "SubMenu"); //If you want to add submenu
sMenu.add(0, 4, 0, "SubOption1").setShortcut('5', 'z');
sMenu.add(0, 5, 0, "SubOption2").setShortcut('5', 'z');
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 0:
// code for option1
return true;
case 1:
// code for option2
return true;
case 2:
// code for option3
return true;
case 4:
// code for subOption1
return true;
case 5:
// code for subOption2
return true;
}
return super.onOptionsItemSelected(item);
}
This may help you.
In the menu.xml
you should add all the menu items. Then you can hide items that you don't want to see in the initial loading.
<item
android:id="@+id/action_newItem"
android:icon="@drawable/action_newItem"
android:showAsAction="never"
android:visible="false"
android:title="@string/action_newItem"/>
Add setHasOptionsMenu(true)
in the onCreate() method to invoke the menu items in your Fragment class.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
You don't need to override onCreateOptionsMenu
in your Fragment class again. Menu items can be changed (Add/remoev) by overriding onPrepareOptionsMenu
method available in Fragment.
@Override
public void onPrepareOptionsMenu(Menu menu) {
menu.findItem(R.id.action_newItem).setVisible(true);
super.onPrepareOptionsMenu(menu);
}
