To change the navigation icon you can use:
Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.my_icon);
To change the overflow icon you can use the method:
toolbar.setOverflowIcon(ContextCompat.getDrawable(this, R.drawable.ic_my_menu);
If you would like to change the color of the icons you can use:
with a Material Components Theme (with a MaterialToolbar
for example):
<com.google.android.material.appbar.MaterialToolbar
android:theme="@style/MyThemeOverlay_Toolbar"
...>
<style name="MyThemeOverlay_Toolbar" parent="ThemeOverlay.MaterialComponents.Toolbar.Primary">
<!-- color used by navigation icon and overflow icon -->
<item name="colorOnPrimary">@color/myColor</item>
</style>
With an AppCompat Theme:
<android.support.v7.widget.Toolbar
app:theme="@style/ThemeToolbar" />
<style name="ThemeToolbar" parent="Theme.AppCompat.Light">
<!-- navigation icon color -->
<item name="colorControlNormal">@color/my_color</item>
<!-- color of the menu overflow icon -->
<item name="android:textColorSecondary">@color/my_color</item>
</style>
You can also change the overflow icon overriding in the app theme the actionOverflowButtonStyle
attribute:
With a Material Components Theme:
<style name="AppTheme.Base" parent="Theme.MaterialComponents.DayNight">
<item name="actionOverflowButtonStyle">@style/OverFlow</item>
</style>
<style name="OverFlow" parent="Widget.AppCompat.ActionButton.Overflow">
<item name="srcCompat">@drawable/my_overflow_menu</item>
</style>
With an AppCompat theme:
<style name="AppTheme.Base" parent="Theme.AppCompat.Light">
<item name="actionOverflowButtonStyle">@style/OverFlow</item>
</style>
<style name="OverFlow" parent="Widget.AppCompat.ActionButton.Overflow">
<item name="srcCompat">@drawable/my_overflow_menu</item>
</style>
