Android Question [Solved] canvas.drawtext with csbuilder: colors

[Pflichtfeld]

It is possible, to pass a csbuilder-object to the text-parameter of a canvas.drawtext. But its colors are overwritten by the color-parameter of the drawtext-method. It is not accepted, to pass anything else then an int for the color-parameter.
Is there a way, to get the colors of the csbuilder-object in drawtext of canvas?

Canvas.DrawText doesn't work with CSBuilder.

I don't know what you are trying to do but you should check BBCodeView.

Thank you Erel,
I wanted to display severel numbers in one line in different colors in a drawing. Did it now with canvas.measuretext.

Another option is to set Label.Text and then draw it with Label.Snapshot (set the label type to B4XView).

 

[Pflichtfeld]

Even if the label is invisible?

See TextToBitmap: https://www.b4x.com/android/forum/threads/drawing-multiline-text.103845/#content

Perfect! Thank you!
May I ask you a question about the given example?

Sub TextToBitmap (Width As Int, Fnt As B4XFont, Clr As Int, Text As Object) As B4XBitmap
   Dim lbl As Label
   lbl.Initialize("")
   Dim x As B4XView = lbl

1. are the lines:

   Dim lbl As Label
   lbl.Initialize("")

cross-platform?

2. Would this also do? (but there is no initialize-Method for a b4xview)

Sub TextToBitmap (Width As Int, Fnt As B4XFont, Clr As Int, Text As Object) As B4XBitmap
   Dim x As B4XView

2. Would this also do?

no. You are not doing anything useful here.

 

[Pflichtfeld]

It seems that I have not understood this crossplattform topic:
I thought that all the b4xviews are crossplatform and the 'normal' b4a-views are not.
So I assumed, that

Dim lbl As Label
lbl.Initialize("")

would not be crossplatform. Isn't that right?

 

[Erel]

1. Yes they are cross platform because Label type exists in all three platforms.
2. As @DonManfred wrote it is not doing anything. The view must be initialized and you can't initialize a B4XView directly as it is a wrapper for all types of views.

Again a big step forward for me! Thank you Erel an DonManfred!
