Android Button – Remove Shadow and Border from Button with Image on it

We can remove the border and shadows from a button by adding the following style code in your activity_main.xml file. Or what ever your XML file is.

style="?android:attr/borderlessButtonStyle"

Code for button. We are setting an image as the background.

  <Button
        android:id="@+id/button"
        style="?android:attr/borderlessButtonStyle"
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:background="@drawable/gear"
        android:onClick="launchSettings"
        android:textSize="12sp"/>

Inkscape – Center objects on page

Select the objects you want to center

Go to Object -> Align and Distribute… or Ctrl + Shift + A

In the right hand side you should get the Align and Distribue box. Make sure that “Treat selection as group” is selected if you want the objects to mantain the distance between themselves.

Hit the “Center on vertical axis” and “Center on horizontal axis”
