Android: how to determine the last fully visible email in TextView?

Question

I am trying to create a book. And now I have a long text that fills the entire screen, and even part of the text goes beyond the screen. I want to know how to find the last letter that is fully displayed on the screen so that I can split the text into pages.

For example, all lines before

"Bad news, Vernon," she said ...

- fully visible text, and the remaining text should be moved to another page.

Like this (another page of text begins with "Bad News")

Here is the layout I used in the example above

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="10dp">

<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="...some text..." />
</RelativeLayout>
