For what you need a loop if you only want to set the text from one file to the Label?
Your first code will put the

B4X:

"3.text"

into your label
Your second code will put the

B4X:

"1.text"

into your label

Before getting a code sample you must explain more in detail what exactly you want to do!

I could not work to change the article by clicking forward and back.

What does clicking forward and back mean.
Clicking where on what?

When I click on the button, I get the text files in the label.


next(forward) button click =1.txt(label)
next(forward) button click =2.txt(label)
next(forward) button click= 3.txt(label)
.....


back button click =3.txt(label)
back button click =2.txt(label)
back button click= 1.txt(label)
.....
.....

I tried a different method.
It works very well.
But he wants long code. Is there a shortcut?

How to do it with for-next?

you should work with a counter that you increase or decrease depending on which button is pressed.

if button2 is your next button it could be something like this

B4X:

Sub Button2_Click
if counter <3 then
  counter=counter+1
  label1.Text=File.ReadString(File.DirAssets,counter&".txt")
End If
End Sub

I guess I did not need the (for-next) method.
