The default size of the android checkboxes were too small for my purposes, so I changed their overall size, however with their new size their borders now are horribly thick.
In what way could I change the thickness? I quite like the default behavior of the checkboxes, so the only thing I would like to change is the thickness of the border.
Code used to make the checkbox larger:
<CheckBox
android:id="@+id/item_switch"
android:layout_width="160dp"
android:layout_height="160dp"
android:button="@null"
android:background="?android:attr/listChoiceIndicatorMultiple"/>
From this SO answer.
