Does anybody know how to set padding between the ActionBar\'s home icon and the title?
If you are using toolbar from AppCompat (android.support.v7.widget.Toolbar, >= revision 24, June 2016), the padding between the icon and the title can be changed with the following value :
app:contentInsetStartWithNavigation="0dp"
To improve my answer, you can use it on your toolbar directly inside your activity or you can create a new layout file for your toolbar. In this case, you just have to import your toolbar's @id using the include property on each needed views.
You can then import your layout on your activity.xml
