Android Question different colors in the text of a label

[Andie]

I know that parts of a label's text can have different colors. This is done via csbuilder.

But how can I change the color of a certain word, which beforehand is not known, but will be set later by the user?
The structure of a solution could be:

Dim text as String = "big problems need big solutions"
Dim word as String = "big" 'is set by user during runtime
Dim colored_text as CSBuilder = ColorChange(text, word, "red")

label.text = colored_text

However, the question is: How can I realize ColorChange?

CharSequence / CSBuilder Tutorial

B4A v6.80 adds several new features related to the ability to format rich strings. CharSequence is a native interface in Android SDK. A String is one implementation of CharSequence. There are other implementations of CharSequence that provide more features and allow us to format the string...

Of course I know this tutorial, Manfred. But it doesn't solve my problem.

Maybe I was not clear enough: The part of the label's text, which will have a different color, is not known beforehand. The user, when running the code, should be able to select a word which then is displayed in a different color.

you need to build it using CSBuilder based on the Text the user selected. You need to build a solution for yourself for this.

Okay, I can use Regex.Split with the user's word as split parameter and then put it together like: part1 + word + part2.
My hope was, that a more elegant method would exist.

Not that i know of. At least i can´t remember.

You can try to search the forum; maybe there is a similar question asked in the past and hopefully a suiteable answer

My hope was, that a more elegant method would exist.

You should look at @Erel 's example here: https://www.b4x.com/android/forum/t...ul-alternative-to-autocompleteedittext.19379/
Specifically the "AddItemsToList" method, since Erel wrote it I'm pretty sure the method he uses will be the most elegant available

 

[Andie]

The answer was already given (by Erel):
This sub searches for matches and uses CSBuilder to mark the matches.

Another option is to use BBLabel: [B4X] BCTextEngine / BBCodeView - Text engine + BBCode parser + Rich Text View

Is it suitable for a label which is a view in an item layout of a PCLV?

 

[Erel]

It is a BBLabel not Label. Better to reuse the BBLabels with PCLV.
