QUESTION
I added a context that contains a useReducer
hook to my Ionic React app. I'm seeing some strange behavior: when I update the context value with a dispatch
call, then a consumer component will be updated on the page, but the exact same component on the tab bar does not get updated.
I followed this tutorial.
When I add console.log
statements to check whether the components are being reloaded, I see that the component placed in the tab bar () is not being reloaded even though the context value has changed.
When I add console.log
statement to check for re-rendering in my context provider, I see that it doesn't get re-rendered when a dispatch
is called, either.
It seems like the context is being updated locally rather than globally. There is a comment in this answer:
You are updating your state correctly using a reducer but it will only update local component state not the global context state.
That sounds a lot like the problem I am having here.
Here's some code:
MyContext.tsx
...ANSWER
Answered 2022-Feb-10 at 11:29Take a look at your reducer. Instead of modifying state in immutable way you simply overwrite property without creating new reference, therefore context value never updates.
Some components may 'see' this change when they get rerendered because of some reason - local state change, prop change etc. They will reach context, look into provided object and see new value.
To fix it use spread operator to create new objects with keys from previous state and updated total
property.
QUESTION
Using Jetpack Compose and the accompanist pager, I'm trying to create a HorizontalPager
where:
- Edges of items to the left and right of current item are shown
- There is a max width to the
Pager
items
As an example, I wrote the following code (for simplicities sake, I made Text
items, but in reality, I'm actually making more complex Card
items):
ANSWER
Answered 2021-Nov-02 at 21:45The page size is controlled by the HorizontalPager.contentPadding
parameter.
Applying widthIn(max = 200.dp)
to your text only reduces the size of your element inside the page, while the page size remains unchanged.
Applying more padding should solve your problem, for example, contentPadding = PaddingValues(100.dp)
looks like this:

QUESTION
I'm trying to learn how to scrape webpages with dynamic HTML using requests
library in Python. I've been able to get the HTML but I can't figure out how to actually get the data for different pages. If you notice on the bottom of the image there are page numbers:
- How can I specify page number with
requests.post
- How can I know how many pages are available? Would it be as easy as a page range and then
try
andexcept
? - How can I know which arguments could be used for my
data
dictionary inrequests.post
?
Here's how I access the requests:
...ANSWER
Answered 2020-Oct-21 at 22:23The data on that page is loaded dynamically using javascript so you can't just get it with requests from that page. Working with the Developer tag in the browser, you can intercept the xhr generating the data and use that with requests. That's what it looks like in this case.
QUESTION
I'm trying to build an Android application using the new ViewPager2. I've added two ViewPagers, separated by a view, and when you swipe, both viewpagers should move. Both view pagers are moving correctly but upon completion of the gesture, the swiped view flashes and the non swiped view reloads, as demonstrated by the attached gif. Here is my code for the Activity, ViewPagerAdapter, and Fragment. Any help is appreciated
...ANSWER
Answered 2020-Oct-12 at 17:24You can try to use adapter.setOffscreenPageLimit = n
. It sets the number of pages that should be retained to either side of the currently visible page(s). Pages beyond this limit will be recreated from the adapter when needed If you have a limited number of pages.
More details are here.
