Alpha Animation on Label

[Bill Norris]

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.

Take a look at the attached sample project.

When I try to compile your app, I get this:

AndroidManifest.xml:10: error: No resource identifier found for attribute 'hardwareAccelerated' in package 'android'

Maybe you're using an older SDK, ok, I've fixed that.

Take a look at the attached sample project.

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"?)

Yes, it fades the text as the OP requested.

Yes, it fades the text as the OP requested.

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)

This is the APK of the attached sample in case you want to take a look.

Yes, I see what you mean, I think I typed too fast.

But you are still the man, Dude!

Thanks

And thank you for pointing out my mistake.
