I attach the test I did on the
Samsung S6 .......... Xiaomi Mi 9

Here the tests on Samsung Tab3 - 7" (T310)

All tests were successful. Now we can continue to post images and photos all day. But it wouldn't solve the problem.
Are you using the original project I have attached?

Yes, as I said, I'm using aSample1 from post #2. I didn't make any changes to your project. But don't worry about it. I might take a look at your code and let you know if I find the problem. Thanks.

Unfortunately, if I can't reproduce the error, I can't correct it. I am using your own devices.

My tests are done on Samsung Tab2, Tab3, S6. Asus Zenfone 2, Xiaomi Mi 9, Honor 9, Huawey MediaPad M3, Huawey MediaPad T3, Viko Jam, iPhone 6.

Hi SD, I had a look at your code and the reason I am seeing the corruption is that TransitionAnimated doesn't necessarily complete before the user clicks the label again. Adding a Wait For to TransitionAnimated fixes that problem but then the GUI is less responsive. Adding a flag to TransitionAnimated to terminate the animation early and go straight to the end state fixes the problem. Dangles has a similar issue which I didn't bother fixing since I think I prefer BottoMenu without the Dangles animation. Also, removing the call to Dangles and the following Sleep(500) makes the interface a lot more responsive. Anyway, thanks for the great library.

 

[Star-Dust]

I deliberately avoided speeding up the closing of the previous animation, because it could create other problems.

In rel. 1.41 with the "semaphore" flag I can stop the following animations until the previous one completes.
You may have used a version earlier than 1.41, otherwise you have not experienced this problem

If semaphore=False Then 
    semaphore=True
    ' .... other code
    Dangles(B4XL)
    Sleep(500) 'It waits 500ms, i.e. the duration of the animation, before reactivating the semaphore FLAG
    semaphore=False
END IF

 

[CaptKronos]

I am definitely using 1.41 since I can see your semaphore code. I don't think it is safe to assume the animation will complete within the exact specified duration, at least it doesn't seem to work on my devices. Anyway, I have now also fixed the Dangles code. I'll PM the code to you, just in case you want to take a look. (I have only changed the B4A elements.) It is strange that the problem doesn't show up on your devices since on the two devices (S8 and an old Yotaphone) I have tried the problem materializes almost immediately.

 

[Star-Dust]

The animation lasts around 400ms, so 500ms is enough. It may be that for some reason your devices are slower, perhaps some other app installed. I always keep my devices efficient and cleaned up to prevent external factors from affecting the tests.

In any case, I will try to find a solution for devices that can present such problems. I'll probably use Wait For's suggestion

 

[CaptKronos]

The version I sent you doesn't require Wait For. You are probably correct about slower devices. It's a shame that my S8 now falls within that bracket!

My S6 is older it doesn't have this problem, so I suggest you check it out

Update rel. 1.6

Good day,

Very good work. Is it possible to change the color at runtime?
set BackGroundColor is not working

[Star-Dust]

In the first post there is the source code, you can modify it to get this function

Thank you very much, I found it.
