B Bill Norris Active Member Licensed User Longtime User Mar 9, 2012 #1 I wish to have a label and its text be invisible, then use animatealpha to make it fade in and stay visible in response to a particular event. The particular event is not relevant here, just the steps for the fade in. If I set the aspha to 0 in designer, the text of the label is still visible when the activity loads. I want the text to be invisible as well until the animation make it appear. Last edited: Mar 9, 2012

I looked at your code in a text editor (since I couldn't load it into B4A) and saw the line: Label1.TextColor = Colors.ARGB(AlphaValue, 255, 255, AlphaValue) Did you intend to put the AlphaValue at the end? (That changes the font color as it's fading in/out, which maybe you intended as a "feature"?) Upvote 0

The first "AlphaValue" (in the Alpha spot) fades the text. The second one is changing the color, isn't it? You have: Colors.ARGB(AlphaValue, 255, 255, AlphaValue) And the format for ARGB is Colors.ARGB(Alpha As Int, R As Int, G As Int, B As Int) I think that the 2nd AlphaValue should just be 255 (or whatever color is wanted) Last edited: Mar 9, 2012 Upvote 0
