If you are Using Toolbar set as Actionbar (setSupportActionBar(Toolbar)) or Actionbar alone:

In your Activity:

<pre><code>override fun onCreateOptionsMenu(menu: Menu?): Boolean {
 getMenuInflater().inflate(R.layout.menu_home, menu)
 return true
}
</code></pre>

In <code>res -&gt; menu</code> folder add a new file named <code>menu_home</code> (if menu folder does not exists make one):

Add as many items you need to <code>menu_home</code> file:

<pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"&gt;
 &lt;item
 android:id="@+id/item_01"
 android:title="@string/my_title"
 android:icon="@drawable/my_icon"
 app:showAsAction="ifRoom"/&gt;
 ...
&lt;/menu&gt;
</code></pre>

<code>showAsAction="ifRoom"</code> makes icon available in Toolbar if there is room for it. you also have an option for <code>never</code> as it goes inside the popup menu.

<hr>

If you are using Toolbar only (without setting as Actionbar):

<pre><code>&lt;androidx.appcompat.widget.Toolbar
 android:id="@+id/toolbar"
 android:layout_width="match_parent"
 app:menu="@menu/menu_home"
 android:layout_height="?android:attr/actionBarSize"
 android:background="?attr/colorPrimary"
 app:popupTheme="@style/AppTheme.PopupOverlay" /&gt;

You need to create a menu to achieve this task. For example;

<code>res/menu/menu_main.xml</code>:

<pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"&gt;
 &lt;item
 android:id="@+id/new_item"
 android:icon="@drawable/new_icon"
 app:showAsAction="ifRoom"&gt;
 &lt;/item&gt;
&lt;/menu&gt;
</code></pre>

If you already have a menu then you can continue with it.

After you have created the menu, you need to inflate it.

<pre><code>public class MainActivity extends AppCompatActivity {
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
 // Inflate the menu; this adds items to the action bar if it is present.
 getMenuInflater().inflate(R.menu.menu_main, menu);
 return true;
 }
}
</code></pre>

Refer this for more details about using the menu resource: <a href="https://developer.android.com/guide/topics/resources/menu-resource" rel="nofollow noreferrer">https://developer.android.com/guide/topics/resources/menu-resource</a>

I have create an Android application using <code>NavigationDrawer</code>. When the application is created, there is one icon menu set by default, placed in the left of the toolBar. And my aim is to add another icon placed, for example, in the right of the toolbar. I have tried many tutorials by following them step by step, by I can't achieve it. Could anyone help me?

我使用NavigationDrawer创建了一个Android应用程序。创建应用程序时，默认情况下会设置一个图标菜单，放在toolBar的左侧。我的目标是添加另一个图标，例如，在工具栏的右边。我试过很多教程，一步一步地去做，但我做不到。有人能帮我吗？​​
