How to change Toolbar navigation icon and options menu margin

问题

Is there any way to change the left margin of the Navigation icon and the right margin of the Action items in Toolbar?

回答1:

I went through the Toolbar source code to find a solution and it turned out to be pretty simple.

Toolbar uses two styles to style the toolbar and the navigation icon. Just had to override those styles with my own.

<style name="myToolbarNavigationButtonStyle" parent="@style/Widget.AppCompat.Toolbar.Button.Navigation">
    <item name="android:minWidth">0dp</item>
    <item name="android:padding">12dp</item>
    <item name="android:scaleType">centerInside</item>
</style>

<style name="myToolbarStyle" parent="@style/Widget.AppCompat.Toolbar">
    <item name="android:paddingRight">10dp</item>
</style>

<style name="AppTheme" parent="AppBaseTheme">
    <item name="toolbarStyle">@style/myToolbarStyle</item>
    <item name="toolbarNavigationButtonStyle">@style/myToolbarNavigationButtonStyle</item>
</style>
