SearchListView | 带搜索栏的 listview，轻拉出现搜索栏，用力拉出现下拉刷新 | Frontend Framework library

I have an activity that has a SearchView that I use to enter a query, my app then uses to query to access an API. My activity further contains a fragment, and within this fragment I have my observer.

Further I have my ViewModel, which makes the API call when given a query. However, my observer is never notified about the update, and thus my view never updates. Unless I call it directly from my ViewModel upon initiation. I'll show it specifically here:

ViewModel

so I am working on my first project with Xamarin Forms and I encountered a problem: Items in my listview are unclickable/Unselectable on Android Emulator. I don't know if it works on iOS. Hope you guys can help me!

Here's what I did: When the user enters a code in a searchbar, the codes from objects in an observableCollection are compared to the text from the searchbar. if it matches with any of the codes from any objects, the concerned objects are put in an IEnumerable<> that I use for my Listview.ItemSource. I am able to display the Collection, but when I click on an Item, absolutely nothing happens.

Important Note: It works sometimes when I spam a certain item.

Here's the matching codes search method in a View:

I'm currently stuck with applying pagination to my Django view codes. Basically, paginate_by seems automatically to work with queryset attribute in CBV. But, in my case, I'm not just using queryset attribute. I'm using filtered queryset on my own. How can I apply pagination to my codes?

As get_queryset() returns only one queryset and I need the length of the queryset search_store to the template file. So, I'm trying to send the value to the template through get_context_data.

I know I can get a length of a queryset through {{ queryset|length }}, but for some reason, it only returns a length of queryset separated by pagination, so I only get a partial length.

As you see the code, I'm trying to print search_stores.count(), and I need get it in get_context_data from get_queryset. Can anyone let me know how I can do that?

I'm currently trying to convert my FBV function to a CBV one.

I'm currently trying to convert my FBV codes to CBV. get_context_data is working well by returning contexts that I put in. However, get_queryset() returns NOTHING for some reason. To double-check, I tried to print search_stores right before returning it and it printed the queryset that is supposed to be printed. However, when I printed it on Django template, by typing {{ search_stores }}, it shows nothing. Am I using get_queryset in a wrong way?

I have 10 movie names in SQLite database. I am searching in the database using SearchView and storing result data into ArrayList and then displaying in custom ListView. The problem is, it works sometimes only. For example, when I search for "the god" or "god" it returns "The Godfather" but when I search for "the shaw" or "shaw" it doesn't return "The Shawshank Redemption". Also, when searching "the" it returns all the movie names starting with "the" like The Godfather, The good, bad and the ugly, the Shawshank redemption etc. I have the below code. Also "Not found" toast is never getting triggered.
