<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:orientation="vertical"
   android:gravity="center"
   android:background="#000"
   tools:context=".MainActivity">
   <DigitalClock android:id="@+id/digital"
      android:layout_width="wrap_content"
