Default ActionBar with Settings button

Although I am new in android developing, lately, I have been trying to add a settings button in the default ActionBar that Android Studio provides (as shown in the picture below). However, all the tutorials I have stamped on start with changing the app Theme to: android:theme="@style/Theme.APpCompat.Light.NoActionBar"

Is there any way I can avoid changing Theme and just add that setting about in the default ActionBar?

ActionBar that Android documentation suggests

Solution

  • You can do this by inflating your menu to the toolbar. Override this method in your java class. 

    @Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.your_custom_menu,menu);
    return true;
}

    You custom menu should look something like this:

    <?xml version="1.0" encoding="utf-8"?>


    >
<item
    android:id="@+id/night_mode"
    android:title="?attr/theme_text"
    app:showAsAction="never"
    android:icon="?attr/theme_icon"/>
<item
    android:id="@+id/action_about"
    android:title="@string/about_text"
    app:showAsAction="never"
    android:icon="?attr/about_icon"/>
<item
    android:id="@+id/action_logout"
    android:title="@string/action_logout_text"
    app:showAsAction="never"
    android:icon="?attr/logout_icon"/>
