Displaying text using textView() Android

Question

Unsure of how to display text in the xml file, i have code written to output text in the java file but nothing happens when the application is run

TextView tv = (TextView) findViewById(R.id.my_text_view);
tv.setText("Welcome to the Dungeon");

*

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/my_text_view"
android:text="@string/my_text_view"/>

Use this:

<TextView android:id="@+id/my_text_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Example"
    android:layout_gravity="center"
    android:textColor="#656565"
    android:textSize="20dp" />

And then setText
