Android Question Clear edit field immediatly

[andredamen]

I want to clear an editfield. I program it with edtfield.clear. When I log the editfield I see it is empty but on the screen I stil see the old text. Later in the app I fill the editfield. It clears and fill with new text.
What I want: I want the clear the edit field and want to see a clear editfield immediatly on the screen. How can I do this?

editfield.Text = ""

Sorry I already programmed it with edithfield.text = "" I later fill the edit field but I want it on the screen imediatly empty.

Upload a small project showing the problem. It is a bit unclear based on the infos you provided.

editfield.Text = ""

- as mentioned above - does clear the text in the given editfield.

What is an EditField?
Do you mean EditText or B4XFloatTextField or you are using other custom view?

 

[andredamen]

I use: Private edtVeld As B4XFloatTextField

 

[andredamen]

I clear it with: edtVeld.text = "" It clears the field, but not immeditaly on the screen. When I later in the program fill the field I can see it was cleared before.

try to call after setting the text to = ""
Activity.invalidate
this will redraw the whole screen and you should get a cleared textfield

Private Sub btnOpnieuwTossen_Click
	TossenIsGelukt=False
	edtVeld.Text=""

	For ot = 1 To 40
		ToastMessageShow("Toss ronde nummer "& ot,False)
		GaOpnieuwTossen(ot)
	   If TossenIsGelukt Then Exit
	Next
	
End Sub


Private Sub GaOpnieuwTossen(hoevaak As Int)
Dim Doorgaan As Boolean

btnOpnieuwTossen.Enabled=False
MetSterkte= chkSterkte.Checked

txt="DELETE FROM '"& Main.DBTableName1 & "' where datum =  '"&  Main.WelkeTossDatum & "' "   ' alle wedstrijden deze datum verwijderd
Main.SQL1.ExecNonQuery(txt)

'from here it fills a database afther making a toss



    VulEditVeld     ' this will fill the edit field with new data

End Sub

Private Sub VulEditVeld
	Dim Oudetijd As String
	Dim Dummy As Int
	
	
	WieNietIngetost 
	If TossenIsGelukt=False Then Return

	edtVeld.Text = "Indeling toss-wedstrijden "& Main.WelkeTossDatum & CRLF & CRLF

'from here it will fill the field further

End Sub
[\CODE]

It doesn't clear the field on the screen when I say edtVeld.text = "" . It fills from a cleared field when I fill the edtVeld later in the program.

Activity.invalidate

This doesn't work Ilan.

 

[ilan]

does the floatingtextfield has a invalidate method?
if yes try to call it.
or a redraw method.

 

[zed]

I see the code should work.
you are sure not to use edtVeld.Text in another line of code
Personally, this but already happened

 

[andredamen]

No invalidate and no redraw possible.

 

[DonManfred]

It doesn't clear the field on the screen when I say edtVeld.text = ""

If you still dont want provide a example project i´m out here.
I don´t plan to post any further answers here.
Good Luck

I tried to call

B4XFloatTextField1.Text = ""

and it's cleared immediately.

 

[felixl]

Maybe this helps:

textfield.text = ""
sleep(0)

I think your sub is doing some heavy task? sleep allows the UI to refresh, without need to wait for the end of sub execution.

Greetings

You are a lucky one Sagenut.

private Sub LeegEditVeld
	edtVeld.Text=""
	
	edtVeld.TextField.Text = "" 

	edtVeld.Text = "Indeling toss-wedstrijden "& Main.WelkeTossDatum & CRLF & CRLF
	
End Sub

Doesn't work with me.

The question is some how odd, thats why you should upload a minimal example project that demonstrates the following code which you claim it doesn't clear the text. It should cleared the text in any case

B4XFloatTextField1.Text = ""
