How to Easily Replace an Option Menu Item in Android Toolbar

If you're developing an Android application, you might find yourself in a situation where you need to change an option menu item in your toolbar when a specific action is performed. For example, you may have an edit icon that, when tapped, opens a TextView for editing and replaces the edit icon with a save icon once the user is ready to save their changes. This guide will walk you through how to implement this functionality in your app.

Understanding the Problem

In many applications, user editing is common. When the user clicks an edit icon, you typically want to allow them to modify some text. However, once editing is complete, the idea is to replace the edit icon with a save icon. This indicates to the user that their changes can be saved.

The Scenario:

The user clicks the edit icon on the toolbar.

The TextView becomes editable.

After the user has finished editing, the edit icon is removed, and a save icon is displayed instead.

This change in the toolbar helps to inform the user of their current actions and what options are available next.

Implementing the Solution

To achieve this menu item replacement, you'll need to create a method that toggles the visibility of the menu items based on user interaction. Here’s a step-by-step guide:

Step 1: Create the Method For Switching Menu Items

You need to define a method that will handle the visibility of the menu items. This method will take an int id to determine which menu item was clicked.

Here, menu.findItem(id_save) and menu.findItem(id_edit) are used to reference the respective menu items.

The method checks if the edit item was clicked. If so, it hides the edit icon and shows the save icon; otherwise, it does the opposite.

Step 2: Call the Method in onOptionsItemSelected

Next, you need to call your newly created method when a menu item is selected. This is done inside the onOptionsItemSelected method.

The onOptionsItemSelected method listens for user actions on the menu. By calling switchMenuItem(item.getItemId()), the toolbar dynamically responds to user selections.

Conclusion

Replacing option menu items in the toolbar is a straightforward process that enhances user experience in your Android applications. By implementing the above method, you can easily switch the menu items based on user actions, allowing for a more intuitive and responsive interface.

By following the steps provided, you now have the ability to change the edit icon to a save icon with just a click, streamlining the editing and saving process in your apps. Happy coding!
