There’re 2 small questions.
1.how to Slide the slider to browse the text.
2. When the slider reaches the bottom, the button appears and can be clicked, Like most user agreement.

About question 2, I can set the value of the slider, when it equals 1, the button appears.

All you need is solve question 1, thank you all guys.

I think I use scrollbox to build it. But I wish to get better plan

Put the text in scroll box. To detect reaching the end:

Thank you, my old friend, Everynone.

I thought you wanted the button to become visible only if the user scrolls to the bottom of the User Agreement, somewhat forcing the user to read it.

Anyhow, consider marking one of those as Solved.

but in fact, I see the button only when I scroll to the bottom.
