Is there a short way to repeat this code without typing it all ?

    Define a style containing all the common attributes and set style in textview . In your case style may contain , textAlignment , textColor , textSize and if you want layout_width and layout_width also . If you want to change value for only one textview , you can always override that parameter in xml file.

      <style name="TextCommanStyle">
        <item name="android:layout_width">match_parent</item>
        <item name="android:layout_height">wrap_content</item>
        <item name="android:textColor">@color/black</item>
        <item name="android:textSize">20sp</item>
    </style>

    your xml file.

       <TextView
        android:id="@+id/titleTextView"
        style="@style/TextCommanStyle"
        tools:text="Text 1" />

    <TextView
        android:id="@+id/descTextView"
        style="@style/TextCommanStyle"
        android:layout_marginTop="10dp"
        tools:text="Text 2" />


    <TextView
        android:id="@+id/desc2TextView"
        style="@style/TextCommanStyle"
        android:layout_marginTop="10dp"
        android:textColor="@color/teal_200"  // override color if you want
        tools:text="Text 3" />

    In case you want to change textColor or add new attribute to each textview, add to a commom style and it will reflect on all view using that style.
    You can create multiple styles depending upon your use case
