Now we need to add some action buttons in Toolbar, Let’s open menu_main.xml located under res ⇒ menu and add the search menu item as mentioned below.

<menu xmlns:android=""

    <!-- Search -->

    <!-- Settings, should always be in the overflow -->
    <item android:id="@+id/action_settings"

The app:showAsAction attribute specifies whether the action should be shown as a button on the app bar.

ifRoomThe action is displayed as a button if there is room in the app bar for it; if there is not enough room, excess actions are sent to the overflow menu.
alwaysThe action is displayed as a button in the app bar.
neverThe action is always listed in the overflow menu, not displayed in the app bar.

Tip: You can find some icons on the Google Material Icons page.

Tip: If necessary, you can re-order the menu items with the android:orderInCategory attribute in each <item> you need to move.

Adding Images in Application

To import the Image in Android Studio, right click on res ⇒ New ⇒ Image Asset. It will show you a popup window to import the resource. Browse the search icon that you have downloaded from Google Material Icons page , select Action Bar and Tab Icons for Asset Type and give the resource name as ic_search_action and proceed.

To specify the options menu for an activity, override onCreateOptionsMenu() method. For example:

public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(, menu);
    return true;

Handling click events

When the user selects an item from the options menu (including action items in the app bar), the system calls your activity’s onOptionsItemSelected() method. For example:

public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
            // some code
            return true;

            // some codes like toast message
            Toast.makeText(getApplicationContext(), "Congratulations!!!", Toast.LENGTH_SHORT).show();
            return true;

            return super.onOptionsItemSelected(item);


Now you can run you app for testing action buttons.
