QUESTION
I am designing a shopping app via Kotlin & Firebase. I am using recycler view in an inbuilt fragment . There is one activity which is responsible for multiple fragments , for example one fragment is responsible for displaying orders , one fragment is responsible displaying all products etc. I get all my data from firebase & display it in fragments via a recycler view. The issue is that the recycler view scrolls but it does not scroll to the end of the page. Can someone guide me. I have attached two screenshots
(Recycler view does not scroll to the end of the last child i.e "TAP TO KNOW MORE" textview is not visible for the last element of recycler view, it just stops scrolling)
This is how my activity is designed ->

QUESTION
I'm writing an app for playing different audio files (play them in loops). In the app I want multiple files to be able to play simultaneously , but they need to start at the same point. This means additional audio tracks I have activated would only start playing upon completion of an already playing audio file's loop.
My components are currently two -
- App.js (presents different audio files), parent.
- Play.js (present the option to play and stop each audio file), child . I'm trying to pass an update (via hooks) to the parent once an audio file has started to play, but each time I do such an update I lose the functionality the children i.e. I can start playing a file but can't stop it.
This is the code of my child:

QUESTION
I have a code that generates 12 buttons with names from a list. I'd like to pass those names to a function but currently only last text from button is remembered and it's being used for all buttons. Is there a way (except creating all buttons manually), to have it worked, meaning that proper button name will be passed further?
...ANSWER
Answered 2021-May-26 at 13:28It is because you used i inside clicked(). When clicked() is executed, i will be the last button created in the main for loop.
You should instead pass the required note to clicked() using functools.partial() and use this note to update the test label.
Also better create the test label outside clicked() and update its text inside the function.

I've been trying to solve this error for 3 days now and I can't figure out. I keep getting
...TypeError: Object(...)(...).data is undefined whenever i try to go to a specific post using it's id. Importing it from db.
ANSWER
Answered 2021-May-25 at 10:59At first time when query is being executed, data will be undefined so when you try to extract getPost from undefined, it will show error.
To solve this try to use loading state from useQuery and extract data after query is executed.

QUESTION
I have a little web app, that I want to run within a page in a custom post type on my WordPress site. So I thought to just create a new template to put the specific code for this app there and assign this template to the custom post types page.
Sadly Wordpress is not showing me the template in my cpt.
The template file is called fretfind.php and the first lines contain:
...ANSWER
Answered 2021-May-23 at 12:09If this was a page, you could have used a template file called page-{slug}.php, where {slug} is the slug of the specific page (see here: https://developer.wordpress.org/themes/template-files-section/page-template-files/#page-templates-within-the-template-hierarchy).
But since we're talking about CPT there is unfortunately only single-{$posttype}.php and no single-{$posttype}-{$slug}.php (see here: https://developer.wordpress.org/themes/template-files-section/custom-post-type-template-files/#custom-post-type-templates)
However, you can add support for such template files for CPT by adding this code to your theme's functions.php:
QUESTION
I understand that in R it is best to avoid loops where possible. In that regard, I would like to perform the function of the code below but without using the nested loops.
The loops check whether the f'th element of the vector things_I_want_to_find is present in the i'th row of thing_to_be_searched. For example, when both i and f are 1, the code checks whether "vocals" is present in john's row. Because "vocals" is present in john's row, the name and instrument are added to vectors instrument and name. When both loops are complete these two vectors can be combined in a data.frame.
I know that there is the apply() family of functions in R but I don't know if they are able to be used in this case. Has anyone got any helpful hints or suggestions?

Answered 2021-May-18 at 05:23You're using .filter on undefined variable: "Cannot read property 'filter' of undefined".
The issue comes from the way you use the Axios response and not the function you give to the .filter method.
As mentionned in the Axios documentation, you can retrieve response data in the data property from the response:
When using then, you will receive the response as follows:
