[Question] Copy and Paste & Extension

[XverhelstX]

Hello everyone,

I have some more questions about Basic4Android.

1) Is it possible to press a button, and then it copies the text of another label ?

for example, you touch button btnClick, then it copies the text of lblClick (lblClick.text) to a clipboard or something, and then when you are typing in an EditText box, you can paste the text of lblClick.text.

This is a very important feature I need for my app

2) Is it possible to view '.html' files in your browser?
like on your pc: you have file:/.../index.html and you can see it in your browser.

3) Can you detect files with extension?
for example, if you open *.txt* files with the file dialog, a msgbox appear with "TXT file opened and when you open *.html*files, a msgbox appear with "HTML file opened".

Those 3 are important features for my app.

Hope you can help me.

King regards,

XverhelstX


Thank you very much!

1. If it is in the same application then you do not need to copy the text to a clipboard.
Just fetch the text and add it to EditText.Text.
For clipboard you can use this library: http://www.b4x.com/forum/additional-libraries-official-updates/7382-clipboard-library.html#post42139
2. Yes. You can either send an intent to start the browser or you can show the html file in a WebView control. See PhoneIntents for opening the browser with a file/url.
3. Something like: If file.ToLowerCase.EndsWith(".txt") Then msgbox("Text File.", "")

Thanks a lot Erel!

I just found out n°3 though.
but I have a new problem.

So I have one save button and one load button.
when I press the Save button, then I do the following:

DocTypeExt.Add(txtDocType.text)
File.WriteList(File.DirRootExternal, "Doc." & outcome, DocTypeExt)

So it writes from my editText box to a file "Doc.file.ext" in my SD card, but the edittext containts CRLF, so enters. then, when I press the load button:

BodyOutcome = "Body." & outcome
List3 = File.ReadList(File.DirRootExternal, BodyOutcome)
BodyRead = List3
txtBodyDisplay.text = BodyRead

I receive the outcome, but all the CRLF/Enters, are changed with 'Comma's' "," and it starts and ends with "[" and "]" (open and closed brackets).

So I found a way by doing the .replace(",", CRLF) and then all the comma's will be changed by enters. But what then, if the editText already has comma's in the text. something like:

"I go to the market, eat a bagel and go home."

will change in:

"I go to the market
eat a bagel and go home."

I hope u understand what I mean ;D


Thanks (again),

EDIT2: How should I open the file that is in the SD card then? something like:

   Dim tit As InputStream
   tit = File.OpenInput(File.DirRootExternal,"index.html")
   StartActivity(PhoneIntents1.OpenBrowser(tit))

THANKS A LOT! ClipBoard works smooth!

File.WriteList writes each item in a single line. You can replace each CRLF with some unique text (like: ~~~!~~~). Then when you read it you should replace the special text with CRLF.

oh, ok thanks.

is there also a way to replace multiple characters?
like .replace("[","]", crlf) or something?

and

How should I open the file that is in the SD card then? something like:
Code:
Dim tilt As InputStream
tilt = File.OpenInput(File.DirRootExternal,"index.html")
StartActivity(PhoneIntents1.OpenBrowser(tilt))
