How to make text scroll on android screen

Question

I’m wanting to put on a screen a large text.

However I have a small problem when it comes to reading more, the text is simply cut and there is no way to scroll to continue reading.

Someone tells me how to do it?

If I get it right, just put your textview inside a Scrollview.

<ScrollView
  android:layout_width="match_parent"
  android:layout_height="match_parent">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >   

          <TextView
              android:id="@+id/tv_long"
              android:layout_width="wrap_content"
              android:layout_height="match_parent"
              android:text="@string/really_long_string" >
          </TextView>
   </LinearLayout>
</ScrollView>
