I want to create n app like this video.

When I long click on a button it should be selected. And when I click selected
again it should be removed.
Please help please
What have you done so far? Show your blocks.
Use on long click event
I used long click event but after that click event wprk
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select “Download Blocks as Image”. You might want to use an image editor to crop etc. if required. Then post it here in the community.

I have no idea.
Please help
Use the OnLongClick block. When the user long click a button, add the component name or any information that will help you identify which button was long clicked into a list. I don’t know about the color over the image but you can add the checked symbol by just changing the button text.
Also you have to be able to unselect a previously selected button. So when the user long click, first check if the button is already in the list. If it is, then remove that item from the list and change the text to a space.
Thank you Italo for your great information. But One problem that when user LONG CLICK on a particular button ,after release fingers from that button CLICK event working automatically.
I can’t understand that how to prevent automatic CLICK event after pressing long click on that button
That shouldn’t be happening. Are you sure? Please show your blocks.

Yes I am sure. After pressing long click event , automatically click event work
Okk I am showing you
Here Button1. Image = check mark icon
Button 6.image = play button png
if this is really the case, then you could fix it using the not Already Handled parameter…
if not Already Handled
then <add here your existing blocks of the Any button click event>

Dear taifun it’s not working. After
I tried your suggestion I found the same problem. Any Button Click Event automatically occurred after pressing LONG CLICK EVENT
The user is right in my opinion. The clicked event shouldn’t be triggered after the long click event is registered.
I made my own test and it replicates the wrong behavior the user described.

Oops, you are right on that. Thanks @dora_paz.
But we are still trying to find a workaround to what seems to be a bug. The OnButtonClick event is triggered together with the OnButtonLongClick event. It shouldn’t be like that.

yes, this is a bug…
did you try it in MIT App Inventor? In case there is the same issue, then the MIT App Inventor team should fix it, else the Kodular team…
