It is encouraged for Android programmers to store String values in res/values/strings. If you add a String here, you can reference it in your xml file like so: android:text="@string/mystring"

Declare this in string.xml and use:

<string name="sna">Synonyms &amp; Antonyms</string>

And simply call this in:

<TextView 
    android:text="@string/s_n_a"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="@color/White"
    android:layout_gravity="center"
    android:textAppearance="?android:attr/textAppearanceLarge"/>
