:sign0060: , Great work, I can make good, thank you

Very nice, thanks for sharing

Looks really great. Thank you for sharing this. Consider making it a custom view. It should probably be simple to add the two required methods.

Yes. I will do it soon.

Man, it never stops with you, does it?

I can't fathom where you come up with these ideas? Just DON'T stop! We love it.

All your contributions are Great! I use many... and shall (soon) contribute (donate).

Personally, I prefer classes over libs since I can learn and modify them to suit my needs.

Check out my latest work in progress - you shall see your handy work at play..

I prefer too, but most of my recent works cannot be written directly in B4A.

It's always nice to see my code in other projects than mine.

Great!

I was creating a class to implement the mask in the EditText, but your solution is better.

I would only suggest the following:

In property "Format":
- Add something like "@l" for all characters in lowercase.
- Add something like "@u" for all characters in uppercase.
- Add a property (or method) to return the text without the mask:
example:
If the format is "##.###.###-##" and typed "12.345.678-90", return is "1234567890".
(this is useful for recording in the database without the mask)

Thanks and congratulations!

Edit :
A function that removes the mask of a string (I used in the class that I was developing):

B4X:

Sub WithoutMask(cString As String, cMask As String) As String
  Dim I As Int
    Dim MaskElements As String
    Dim Result As String
   
    Result      = ""
    MaskElements = "#LAH?"
    For I = 0 To cMask.Length-1
      If (MaskElements.Contains(cMask.CharAt(I))) AND (I<=cString.Length-1) Then
          Result = Result & cString.CharAt(I)
        End If
    Next
    Return Result
End Sub

This EditText fixes a few issues with the standard EditText and adds new features:
- Filter: you can transform any input before the text is changed;
- Mask: you can define an input mask;
- Read-only: you can protect your EditText against changes;
- Error popup: you can display a message in a popup to warn the user:

v1.1:
- It is now a custom view supported by the designer
- I fixed a bug when Format was set after WithSuggestions

v1.2:
- I moved the CompactText function from the example to the library;
- I fixed a bug with SelectionStart;
- I fixed a bug when InputType is set to NONE.

This library does not work with Android versions < 2.

That was my first intent but I realized during the development that it was better to use the filter event. A mask for a name, for example, is too complex to do with mask characters only. If you set something like U???????????????? (with U = upper case), you allow any character, but a name cannot accept numbers. If you set something like ULLLLLLLLLLLLL (with L = lower case), you don't allow space or hyphen and you don't handle properly names with two capitals like "Leneuf-Magaud" or "Di Gregorio".

In the example provided with the library, you should look at the RawText function. It returns the text without the mask characters and it's more efficient than your own example (when you create strings by appending characters, it is a lot faster to use a StringBuilder).

yes ... validating the name only through the mask is complex. The idea was not to validate, it was only to force all characters are uppercase or all lowercase.
For fields of e-mail, for example.
But of course the solution at the time of recording in the database is simple. It was just to avoid typing was possible to type in uppercase when I know that the field will only accept lowercase.

sorry.. I have not seen in the example...my main source of reference was the "Methods and properties.html" file that accompanies the library.

Thanks for the tip of the StringBuilder and explanations.

Today i have first contact with this lib trying to create inputs for serials like 1234-5678-9012-3456 or DF4G-5TR6-ZU8G-BCT5...

I got that easy running including regex-checking the result (decide to show error or not)).

REALLY GREAT Lib, Frederic! *thumbs up*

Very interesting library.

I have a request: when I insert data with format mask "##/##/####", if the Text it's still filled
for example 31/03/2014 and I try to change the first character for example from 3 to 2, the entire text
starting from postition 2 is shifted by one to the right.
Result I must to re enter the entire text because the date become wrong.
It would be nice if only the character typed was changed, keeping unchanged the rest of the text .
Eg:
before 31/03/2014
I type 2 on first position
after result is 23/10/3201
instead of 21/03/2014

All text fields under Android are in Insert mode by default; they switch in Replace mode only when you select some text, and switch back to the Insert mode when the text has been replaced. Thus, to replace the first char, you have to position the cursor behind, hit the delete key, then enter the new char, or you can select the first char and type the new char. If, in my code, I try to force a replacement while I'm in Insert mode, I'll have to handle many particular cases to avoid a big mess in the most common situations, so I prefer to stick to the Android guidelines.

First of all, thanks for this great library.

I have only one question, should be posible to change the definition of mask characters? I'm spanish, and if i put 'Horas: ##:##' for a time input, H is recognize as Hexadecimal. Can i change something in the xml or in the jar to make my 'custom' definition? Thanks.

By laziness, I put a descriptive text directly in the EditText field in my example, but this text should be displayed in a label before the EditText. Same thing for you. Horas should not be in the EditText, but in a separate Label.

Hello, I hope you are doing fine.
I'm trying to use this library to capture a currency field but I have some troubles when assigning the value directly from code (I read the value from a table, but is the same when I assign it directly); for example I have the value "220.50" the expected result when I assign it to the maskedit is: "000,220.50" but I'm getting "000,022.05", I attached a sample of the current result, the code I'm using is the following.

B4X:

          txtAmount.Format = "###,###.##"
          txtAmount.SingleLine = True
          txtAmount.InputType = txtAmount.INPUT_TYPE_DECIMAL_NUMBERS
          txtAmount.Text = sf.Pad(tblExpense.GetValue(6, Row),"0",9,False)

Thanks for your help.

Best Regards,
Robert

I don't know what is sf.Pad. It seems the problem comes from this function.
