Android Paging 3 Tutorial in Hindi - Learn Paging 3 in Android with simple example. In this video, we will learn about paging in android. This tutorial covers step by step on how to implement pagination in android. Learn what is Paging Source, what is Pager and Paging Adapter.
We will be calling an API that supports pagination and use it to implement infinite Scroll in Android. Paging Source defines the way to load data from network i.e. API. Once you have paging source setup - you can define a pager object that is used to define the configuration such as pageSize, maxSize. Paging Adapter is used to show this paging data inside recyclerview.
Pagination improves performance of the app by creating only required objects. Recycler view recycles view whereas pagination library creates only the required objects in the memory. Paging 3 Jetpack Component provides support to implement paging in Android. We have implemented it using HILT and MVVM Architecture Pattern. Learn by creating a simple example in Hindi.
Topics covered -
1. What is Paging?
2. What is Paging Source, Pager, Paging Config, Paging Adapter?
3. Paging Implementation Example
4. MVVM + HILT + Paging 3 Jetpack Component.

I think there is a logical issue in getRefreshKey() fun. First time this function will return null. Then the position of the page will be 1 and it's prevKey will be null and nextKey will be 2 as per the logic in fun load(). Again there will be callback to function getRefreshKey(). As per the logic in this function you minus 1 from the nextKey and it will become 1 and this value i will be used as a position in function load and this fuction will again request for the same page which we have already loaded. Correct me if I am wrong. you can check by this by debugging or dry run.

ye getRefreshKey() function jo h ismey kiya anchor position mee plus 1 ya minus 1 hota h ya phir prevKey ya nextKey mee se plus ya minus karkey return hota h value. Agar anchor position mee plus 1 ya minus 1 hota h tab tu iss function ka logic sahi h hamey desired page milta nahi tu same page milega jo anchor position hold karta h.

Hello sir, hope you will read this comment. I want to implement pagination for firebase's real-time database. Basically, I want to fetch a single model from the database and show it in viewpager2, after that when the user will scroll the screen it should fetch the model again from the database. After searching for 4 days on the internet, I am posting this comment in the hope that you can help me. Questions-> 1. we fetch data from the cloud in the repository class and here we are also calling PagingSource class from the repository, I can not imagining the flow of code. 2. What will be the key for LoadResult

@CheezyCode Жыл бұрын

1. PagingSource is independent of your model class. Paging happens on the model object that you want to show inside your pager. 2. Key depends on the data you are fetching. API should support paging support. (For firebase - Use Firebase Paging Implementation) 3. With/Without DI depends on you. How you have implemented the structure of your app.

override fun getRefreshKey(state: PagingState): Int? . The logic return state.anchorPosition?.let { state.closestPageToPosition(it)?.prevKey?.plus(1) ?: state.closestPageToPosition(it)?.nextKey?.minus(1) will always return 1. I think this logic is not correct because at the begning the prevKey = null and the nextKey =2. this is the first page. And in this function you are substracting 1 from the next key because prevKey is null. So it will return 1. Again in override suspend fun load(params: LoadParams): LoadResult params.key will return 1. the prevKey = null and the nextKey =2 again as per the logic inside override suspend fun load(params: LoadParams) function. So it will always make api request for the same page , i.e 1. Are you getting my point?

@CheezyCode Жыл бұрын

Getrefreshkey first time pe call nahi hota...put a breakpoint and try to debug...do let me know...will add more info

@RahulYadav-vs2wd Жыл бұрын

first time pe agar call nahi hota h tu this function should not return null at all because if it is not called first time , it means page or pages already exist in memory and when page or pages already exist in memory it will never return null. This function also returns null that means it is also called first time and also when you scroll up or down in Recyclerview.
