how to create a menu in android studio

Android Tutorial

Option Menu:

Option Menu is a drop down menu containing options, and appears when a users clicks on Menu button.
For Ex:

We can create an Option Menu with following :

Create a menu xml
Register the menu in Activity
Write code to Handle the Clicks on menu items

1: Create xml for menu

Create a new folder named " menu " in res folder (if menu folder is not there in res folder)
inside this Menu folder create .xml file

here I have created option.xml xml for the option menu in above Image

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

</menu>

android:id: A resource ID that's unique to the item, which allows the application can recognize the item when the user selects it.
android:icon: An image to use as the item's icon.
android:title: A tittle to show.

2: Register In Activity

Override onCreateOptionMenu method and inflate the .xml (here options.xml) inside method

@Override
                     public boolean onCreateOptionsMenu(Menu menu) {
                        MenuInflater inflater = getMenuInflater();
                        inflater.inflate(R.menu.options, menu);
                          return true;
                     }

3: Handle Click Events

When the user selects an item from the options menu (including action items in the action bar), the system calls your activity's onOptionsItemSelected() method. This method passes the MenuItem selected. You can identify the item by calling getItemId(), which returns the unique ID for the menu item (defined by the android:id attribute in the menu resource

To Handle click events override onOptionsItemSelected method

@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection

                                                                       switch (item.getItemId()) {
                             case R.id.ChangeColor:
// write code to execute when clicked on this option
                                  return true;

case R.id.phoneInformation:
// write code to execute when clicked on this option
return true;

case R.id.callInfo:
// write code to execute when clicked on this option
return true;

                                                            case R.id.email:
   // write code to execute when clicked on this option
                                                              return true;

                                                              default:
                               return super.onOptionsItemSelected(item);
                         }
                     }

Option Menu Full Source Code

public classMainActivity extends Activity
{
            @Override
        public void onCreate(Bundle savedInstanceState)
        {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.main);
        }

// Create Option Menu
     @Override
        public boolean onCreateOptionsMenu(Menu menu)
        {
            MenuInflater inflater = getMenuInflater();
            inflater.inflate(R.menu.options, menu);
            return true;
        }

// Handle click events
   @Override
          public boolean onOptionsItemSelected(MenuItem item)
           {
                         // Handle item selection

                                                                       switch (item.getItemId()) {
                             case R.id.ChangeColor:
// write code to execute when clicked on this option
                                  return true;

case R.id.phoneInformation:
// write code to execute when clicked on this option
return true;

case R.id.callInfo:
// write code to execute when clicked on this option
return true;

case R.id.email:
// write code to execute when clicked on this option
return true;

                                                              default:
                               return super.onOptionsItemSelected(item);
                         }
                     }
