Android Question [b4X] [SOLVED] BBLabel line spacing

[Andrew (Digitwell)]

I am using BBLabel to display formatted text.

I am getting different effects on iOS and Android.

iOS Output

Android Output

Relevant code:

    lblWarning.Text = $"[TextSize=${Globals.StdFontSize}][Alignment=Left][Color=#${Misccode.ColorToHex(Globals.gcol_sectext).substring(2)}][Font=MainFont]"$
    lblWarning.Text = lblWarning.Text & $"${Globals.loginwarning}"$   
    lblWarning.Text = lblWarning.Text & $"[/Font][/Color][/Alignment][/TextSize]"$

I have tried to strip to label down to the minimum.
I have tried using Vertical, but it has no effect.

Anyone have any ideas?

Thanks

The textengine seems to have 2 properties:

SpaceBetweenLines and SpaceBetweenCharacters but there is no documentation on how these should be used.

Smart strings can be multiline:

    lblWarning.Text = $"[TextSize=${Globals.StdFontSize}][Alignment=Left][Color=#${Misccode.ColorToHex(Globals.gcol_sectext).substring(2)}][Font=MainFont]
${Globals.loginwarning}
[/Font][/Color][/Alignment][/TextSize]"$

Can you upload a project with the BBLabel and text?

 

[Andrew (Digitwell)]

Here is an example. Displaying as a BBLabel or a CSString

I am targetting a tablet so I am using the 800 x 1280 standard variant. (No other variants in the app)

The output is:

edit: Has to reduce the size of the Attachment as it was too large.

The output is

Where is the requested example project-upload with the BBLabel and text?

 

[Andrew (Digitwell)]

Yes, The file was too large. Have now uploaded a smaller version without iOS.

 

[DonManfred]

Try to reproduce it in a small app and upload it.

 

[Andrew (Digitwell)]

It is now attached to the reply post.

No reason to put this code in B4XPage_Appear.

Update to BCTextEngine v1.92 and add:

te.SpaceBetweenLines = 15dip
te.MinGapBetweenLines = 2dip

 

[Andrew (Digitwell)]

Ok, Thanks.
That has done the trick.

Why 15dip for Spacebetweenlines?

Will this work for any size font?

 

[Erel]

SpaceBetweenLines = the minimum line height
MinGapBetweenLines = minimum gap between lines.
Actual height = Max(measured size + gap, space between lines)
