How to Click on a Recycler List View

[Dogukan_TV (Doğukan TV)]

I created a list for my movie application using Recycler List View. Normally, I was using dynamicComponents, and clicking on a movie required the movie details page to open.But it’s not opening. I click, but nothing happens. Why?

The Extension I’m using

[F/OS] Recycler List View - Render larger data sets efficiently using `RecyclerView` for AppInventor & Distros

Hi dear,

Well, it’s very simple, replace the isDynamic from Dynamic Components with the one from RecyclerList.
Of course, to get the component ID, you also need to replace the GetId block

@zainulhassan

4. Now we can handle click events using Any Button.OnClick event from AnyComponent section. First we will verify whether the click event was not already handled and the component is dynamic using IsDynamic block. Next we will save the uique id of button to id variable by using GetUniqueId block. We will also create a position variable. To extract the position from unique id, we will replace the word button from unique id. Now we can use this position to show a snackbar.

I did as you said. When I clicked on the movie, the details page opened, but the images, movie title, and movie description didn’t load. Why?

I’m sorry, I forgot to do what you said, I did it now but I got an error.
Runtime Error No error message
Note: You will not see another error reported for 5 seconds

I followed your instructions, but I’m still getting the same error.

[Vega_Star]

remove all blocks from then, use this and see the result.

Nope. you are not following the way. see in the OnCreateView you have used kart but in the GetUniqueId you are using kart_ so obviously no surprise to get such error

[Dogukan_TV (Doğukan TV)]

I already did that, but it still didn’t work. I keep getting the same error.

In RecyclerList it’s also important to set the uniqueId in OnBindView

@zainulhassan

3. Inside OnBindView event, we will bind data to the UI. Here we have access to the root view and position. Here we will set the position as text of the button by using SetProperties block.To handle click events on a component, it is recommended to set a unique id by joining component name with the position to that component using SetUniqueId block so that you can access the position later in OnClick event.

In such case upload your sample aia here to resolve your error.

I also tried the blog above. The details page opened, but the text inside, such as the image, movie title, description, and category, did not load.
Also, the movie doesn’t load when you press the “Watch” button; the same applies to the trailer.
Please help, this is my AIA file.

Be careful, while I was testing the AIA, I noticed that you left your Firebase URL without any security rules

Anyway, you just need to add “film” to the search key

[Dogukan_TV (Doğukan TV)]

It didn’t get fixed. Only the first 9 films were fixed, the rest weren’t. Why?

@Dogukan_TV

Only the first 9 films were fixed,

What do you mean by that?
What error are you getting exactly?

[Dogukan_TV (Doğukan TV)]

I normally have 52 movies in the app, but only 9 of them show their detail pages. The detail pages for the remaining movies open, but…Text such as Image, Film Title, Description, Category, and Date is not visible.
Here’s the APK for you to try.

I hadn’t deleted your project yet and I noticed that you have different keys like filma1, filmb1.

You’re setting the uniqueId with "kart" + position, getting values like kart1, kart2.
Then, when a CardView is clicked, you remove "kart" from the uniqueId, ending up with 1, 2, 3, and then you add the prefix "film", getting film1, film2.

When you reach the tenth item, which is filma10,

a uniqueId kart10 is set, and when you click the CardView you generate film10, which of course doesn’t exist.

Below is your project,
I modified the creation of the CardViews by assigning them IDs based not on the position, but on the dictionary key.
