Run the B4J Example rather.

If you want to use B4A, then you have to copy the layout from B4J to B4A and replace all the Textfield to Edittext.

The best cross-platform solution is to use B4XFloattext found in the Xui Views library.

As mcqueccu said, this is about B4J. Examples are almost identical to B4A except some slightly differences in some views names. For example Pane in B4J is Panel in B4A or TextField in B4J is EditText in B4A. On the other hand B4XFloattext is more flexible but not in the purpose of tutorial.

Thank you and mcqueccu for the reply.The example Ex1.b4a is put into the sub-directory Lesson 6 Ex1\B4A

Hello everybody!

I am uploading a series of courses for a B4X (B4J) teaching program for middle and high school students.
The total project consists of 20 different modules with a total duration of approximately 60 hours.

The program is divided into courses where each is accompanied by:

• Brief Theory (in pdf and docx) in English and Greek Language (Spanish translation also available here )
• Power Point Presentations (pptx)
• Examples (solved)
• Exercises (also solved for the teacher).

Since the program is aimed at students with little or no programming knowledge, an attempt was made to hide enough details in order to make it more understandable. So forgive some omissions.

The material uploaded to my github here.
You can download full v2.0 pdf for printing here.
Changes Log file here

If you liked my work a cup off coffee is always welcome. Thank you.

New word files includes and Greek Translation. Some changes to curriculum also made.

There is also a Spanish translation. Many thanks to user profeberja. You can find it on his github here
