Manage the options menu at runtime using Java.

Introduction

In this application we have created an options menu in action bar using java code.

Note :

In this project ActionBar_OptionMenu_Xml_Android_Github we have inflate menu items using xml file.

Defining Options Menu using Java

To create menu items using java code, override onCreateOptionsMenu(Menu menu){ } and add this piece of code inside it,

        MenuItem menuItemOne = menu.add(Menu.NONE,Menu.NONE,101,"Menu Item One");
        menuItemOne.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                Toast.makeText(getApplicationContext(),"Menu 1 Clicked",Toast.LENGTH_SHORT).show();
                return false;
            }
        });
        MenuItem menuItemTwo = menu.add(Menu.NONE,Menu.NONE,102,"Menu Item Two");
        menuItemTwo.setEnabled(false);
        MenuItem menuItemThree = menu.add(Menu.NONE,Menu.NONE,103,"Menu Item Three");
        menuItemThree.setEnabled(false);
        MenuItem menuItemFour = menu.add(Menu.NONE,Menu.NONE,104,"Menu Item Four");
        menuItemFour.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                Toast.makeText(getApplicationContext(),"Menu 4 Clicked",Toast.LENGTH_SHORT).show();
                return false;
            }
        });
        MenuItem menuItemFive = menu.add(Menu.NONE,Menu.NONE,105,"Menu Item Five");
        menuItemFive.setEnabled(false);
        return true;
    }

In above code I’ve added Toast message on MenuItemOne & MenuItemFour. I have dimmed out MenuItemTwo , Three & Five by adding this piece of code menuItemTwo.setEnabled(false); to each

Note :

Using Java code, we can also remove or disable menu items programmatically.

Thank You.
