Pass in an instance of EndlessRecyclerViewScrollListener and implement the onLoadMore which fires whenever a new page needs to be loaded to fill up the list.
Open adle (Module:app) file and add the following implementation ‘ :recyclerview-v7:26.1. The LayoutManager, which is responsible in the RecyclerView for rendering where items should be positioned and manages scrolling, provides information about the current scroll position relative to the adapter. To use RecyclerView, we need to add recycler view dependency. We can use a similar approach with the RecyclerView by defining an interface EndlessRecyclerViewScrollListener that requires an onLoadMore() method to be implemented. You can see this guide for more information. For more advanced cases, Google released its own Paging Library.
For Android University courses it's recommended to use this approach for simplicity.
NOTE: This page is describing a straightforward yet a bit dated solution. Adding a threshold value therefore helps anticipate the need to append more data. To provide the appearance of endless scrolling, it's important to fetch data before the user gets to the end of the list. This data can be used to decide when to load more data from an external source: In both cases, the information needed to implement the scrolling include determining the last visible item within the list and some type of threshold value to start fetching more data before the last item has been reached.
Both are similar in code except that the LayoutManager in the RecyclerView needs to be passed in to provide the necessary information to implement infinite scrolling. The approaches for ListView, GridView and RecyclerView (the successor to ListView) are documented here. They cover a wide range of topics such as Android Wear, Google Compute Engine, ARCore, and Google APIs on iOS. This is done by triggering a request for more data once the user crosses a threshold of remaining items before they've hit the end. a new feature to an existing application. To help us triage faster, please check to make sure you are using the latest version of the library.A common application feature is to load automatically more items as the user scrolls through the items (aka infinite scroll).
Further, edit text should be focusable when contents are empty.Īndroid API version: 29,30 (tested, might be more/all)ĭevice: Pixel 4 Simulator, Note 10 on android 10 Translation animation, moving in from top, anim/moveinfromtop.xmlAlso, when the keyboard shows, focus is lost even if text is in the view requiring 2 clicks by the user.Įxpected behavior: Focus should be gained and kept when a user clicks on an edit text, until keyboard dismissed or focus cleared. If the user deletes all contents, focus is lost. When the user clicks on the view with text inside it, focus will be gained and cursor will show.
Further, when the user clicks the view the keyboard gains pseudo focus and will accept input into the edit text without any cursor showing. How to use RecyclerView using Java in Android Studio with custom Adapter and Modal class - GitHub - sashish2/RecyclerViewJava: How to use RecyclerView using Java in Android Studio with custom Adapt. To request focusing an item view, the view must be focusable and you call View.requestFocus (). Description: An empty edit text is not focusable at all when a user clicks on it. You call RecyclerView.scrollToPosition (position) to request the RecyclerView's LayoutManager to scroll to the given position during the next layout pass (it's asynchronous).
