Hello everyone.
Is it possible to set the font size of numbers for each Text = 30 and the font size of Text = 20 by using GetMetric Device Extension?

I do not believe it is possible to change the font size of just one character, or many individual characters in a textbox. You could probably do something in html with javascript and css.

Android provides a way to change and customize each individual characters to a text based view, maybe someone could implement it.

I hope there is a way to implement it because I tried hard to find some way to change the font size of this character but I was not be able to do it.

I can't test it at the current moment.
The Button related components may not work but the Label and Checkbox components should work.

Show an example for relative size (what are the parameters for this - is it a font size) and for htmlColor - is this a color block/a color name or a hex value ?

But it seems that relativeSize can only be an integer.

Yes. Does that have any problem ?

I'll update it and publish it tomorrow.

Osama was after changing a character in a TEXTBOX :wink:

I think Osama could use labels instead of textboxes, his textbox is readonly.
Rather I wonder what he can do with a multiline textbox or a label.

Thanks @Anke for the help in debugging. I've Solved both and will upload it after I solve the TextBox thing, if possible. Have to dig out through many sources. :sweat_smile:

I didn't notice it was a texbox, sorry.

Waste in Haste.

@Anke and @TIMAI2

Could you please test this version.

Not 100 % sure if it will work, but it should, because EditText extends TextView.

The only next option that I know for now, is SpannableStringBuilder.

My Internet Quota is exhausted so I'm having problems in connecting, so I can't test.

Edit : The toIndex property was taking one less index fixed it and updated this post.

Yes, it seems to work now also with TextBox.

Yes, this seems to work.....

Observations

  1. cannot set a smaller relative size once a larger one is set, without resetting the textbox :frowning:
  2. relative size accepts decimals - e.g. 1.25, 1.5 :slight_smile:
  3. Allows for setting of multiple selections, with different sizes :slight_smile:

Maybe using SpannableStringBuilder might solve this. Wait a while.
