Hi all,
I wanted to fit long text in a label but it seems that CharSequences don't work well with the B4XCanvas MeasureText. I think that the cause is the use of different fonts in the text. Is there another method to do so?
Here is my code:
Thank you
I wanted to fit long text in a label but it seems that CharSequences don't work well with the B4XCanvas MeasureText. I think that the cause is the use of different fonts in the text. Is there another method to do so?
Here is my code:
B4X:
Sub Activity_Create(FirstTime As Boolean)
'Do not forget to load the layout file created with the visual designer. For example:
Activity.LoadLayout("1")
FitTextInLabel(Label1,"One very long text in Android")
Label3.Text = Label1.Text
Dim cs As CSBuilder
cs.Initialize.Color(Colors.Green).Typeface(Typeface.FONTAWESOME).Append(Chr(0xF17B)).PopAll.Append(" One very long text in Android")
FitTextInLabel(Label2,cs)
Label4.Text = cs
End Sub
Private Sub FitTextInLabel(lbl As Label, txt As Object)
Private dt As Float
Private limit = 0.5 As Float
Private stp = 0.5 As Float
Private cnv As B4XCanvas
Dim mylbl As B4XView = lbl
cnv.Initialize(lbl)
Dim r As B4XRect = cnv.MeasureText(txt, mylbl.Font)
Dim w As Float = r.Width
dt = mylbl.Font.Size
Do While (dt > limit Or w > mylbl.Width)
dt = dt / 2
r = cnv.MeasureText(txt, mylbl.Font)
w = r.Width
If w > mylbl.Width Then
mylbl.TextSize = mylbl.TextSize - stp
End If
Loop
lbl.Text = txt
End SubThank you
