Centering drawable-left image in android Button in XML

To center a button drawable left need adjust the padding of button and its drawable left padding.
Giving the Button a fixed width we can do this.

 

 <Button

        android:layout_below="@+id/imgSave"

        android:id="@+id/btninvSearch"

        android:layout_width="170dp"

        android:layout_height="wrap_content"

        android:drawableLeft="@drawable/ic_action_camera"

        android:drawablePadding="0dp"

        android:paddingLeft="40dp"

        android:paddingRight="0dp"

        android:paddingTop="12dp"

        android:paddingBottom="12dp"

        android:gravity="center"
